How to Use ZKSync for Faster and Cheaper Ethereum Transactions

ZKSync revolutionizes Ethereum transactions by making them faster and up to 100x cheaper through its innovative Layer 2 scaling technology. Built on zero-knowledge rollup technology, ZKSync processes transactions off-chain while maintaining Ethereum’s security guarantees, addressing the network’s persistent congestion and high gas fee challenges. For crypto futures traders and DeFi users, ZKSync offers a practical solution to execute transactions efficiently without sacrificing the security and decentralization that Ethereum provides. According to the official ZKSync documentation, the protocol batches hundreds of transactions into a single Ethereum transaction, dramatically reducing per-transaction costs while maintaining cryptographic proof of validity. As Ethereum continues to face scalability limitations, understanding how to leverage Layer 2 solutions like ZKSync becomes essential for anyone looking to trade, swap, or interact with Ethereum-based protocols cost-effectively.

Key Takeaway: ZKSync significantly reduces Ethereum transaction costs by up to 100x through zero-knowledge rollup technology that batches transactions off-chain. It processes transactions faster than Ethereum’s base layer while inheriting its security model. The platform is accessible to beginners through simple wallet integration, supports real-world applications including DeFi, NFTs, and payments, and outperforms many Layer 2 alternatives in scalability and cryptographic security. For traders managing frequent transactions or small-value transfers, ZKSync eliminates the cost barrier that makes Ethereum Layer 1 impractical for everyday use.

How to Speed Up an Ethereum Transaction?

Ethereum’s base layer faces inherent speed limitations that affect every user from casual traders to institutional participants. Understanding these constraints and how Layer 2 solutions address them is fundamental to optimizing transaction execution.

What Makes Ethereum Transactions Slow?

Ethereum’s Layer 1 processes approximately 15-30 transactions per second, a limitation rooted in its proof-of-stake consensus mechanism and block structure. Every transaction must be validated by the entire network, creating a bottleneck during periods of high demand. When network activity spikes—during NFT mints, DeFi protocol launches, or market volatility—the mempool fills with pending transactions competing for limited block space. This competition drives gas prices higher as users bid to prioritize their transactions.

The block time of approximately 12 seconds means that even under optimal conditions, transaction finality takes time. For traders executing time-sensitive operations like liquidation prevention, arbitrage, or futures position management, these delays create execution risk. Network congestion can push confirmation times to several minutes or even hours during extreme periods, making Ethereum Layer 1 unsuitable for high-frequency or cost-sensitive operations.

How ZKSync Solves the Speed Problem

ZKSync addresses Ethereum’s speed limitations through zero-knowledge rollup technology, which processes transactions off-chain while posting cryptographic proofs to Ethereum Layer 1. According to Nansen’s analysis, ZKSync can process thousands of transactions per second by batching multiple operations into a single proof submitted to Ethereum.

The rollup architecture works by executing transactions in a separate environment, generating a zero-knowledge proof that validates all state changes, and then submitting only this compact proof to Ethereum. This approach reduces the data load on Ethereum’s base layer while maintaining security guarantees. Each ZKSync block contains a validity proof—a cryptographic guarantee that all transactions in the batch were executed correctly according to the protocol rules.

For practical trading applications, this means near-instant transaction confirmation on ZKSync with final settlement to Ethereum occurring in batches. A trader swapping tokens on a ZKSync-based DEX experiences confirmation in seconds rather than minutes, with transaction costs reduced by 90-100x compared to Ethereum Layer 1. The speed improvement becomes particularly valuable for strategies requiring multiple transactions, such as yield farming position management, NFT trading, or frequent portfolio rebalancing.

Is ZKSync Built on Ethereum?

Understanding ZKSync’s relationship with Ethereum clarifies both its capabilities and its security model, which directly impacts trading risk assessment.

Understanding Layer 2 Solutions

Layer 2 solutions are protocols built on top of existing blockchains to enhance scalability without modifying the base layer. They operate by moving transaction execution off-chain while using the underlying blockchain for security and final settlement. This architecture allows Layer 2 networks to achieve higher throughput and lower costs while inheriting the security properties of the base layer.

Layer 2 solutions differ fundamentally from sidechains or independent blockchains. Sidechains maintain their own consensus mechanisms and security assumptions, creating additional trust requirements. Layer 2 solutions, by contrast, derive their security directly from Ethereum through cryptographic proofs or fraud-proof mechanisms. This means that even if every ZKSync validator acted maliciously, users’ funds remain protected by Ethereum’s security guarantees.

For traders, this distinction matters when assessing platform risk. Funds on ZKSync are ultimately secured by Ethereum’s validator set and consensus mechanism, not by a separate token or validator network. This security inheritance makes Layer 2 solutions like ZKSync fundamentally different from bridging to alternative Layer 1 blockchains, where security depends entirely on the destination chain’s consensus.

ZKSync’s Connection to Ethereum

ZKSync functions as a Layer 2 scaling solution that settles all transactions to Ethereum Layer 1. Every batch of ZKSync transactions is accompanied by a zero-knowledge proof submitted to an Ethereum smart contract, which verifies the proof and updates the state accordingly. This means that ZKSync’s security is mathematically guaranteed by Ethereum—if a proof is accepted on Ethereum, the transactions it represents are as secure as any Ethereum transaction.

The protocol maintains account balances and transaction history in its own state tree, but this state is anchored to Ethereum through regular proof submissions. Users can withdraw funds from ZKSync to Ethereum Layer 1 at any time by submitting a withdrawal request, which is processed through the Ethereum smart contract after the relevant proof is verified. This exit mechanism ensures that users always maintain control over their funds regardless of ZKSync’s operational status.

For practical trading purposes, this architecture means that assets on ZKSync carry the same security guarantees as assets on Ethereum Layer 1, with the added benefits of faster execution and lower costs. A trader holding USDT on ZKSync can interact with ZKSync-based protocols with confidence that their funds are ultimately secured by Ethereum’s consensus mechanism. The trade-off involves slightly longer withdrawal times when moving funds back to Layer 1, typically ranging from a few hours to a day depending on proof submission frequency.

How to Avoid Ethereum Transaction Fees?

Reducing transaction costs on Ethereum requires moving operations to Layer 2, and ZKSync provides one of the most cost-effective solutions available as of 2026-06-17. This section provides a complete workflow for setting up and using ZKSync.

Step 1: Setting Up a Wallet

ZKSync supports integration with popular Ethereum wallets including MetaMask, WalletConnect-compatible wallets, Argent, and hardware wallets like Ledger and Trezor. MetaMask remains the most widely used option for its simplicity and broad compatibility with Ethereum applications.

To connect MetaMask to ZKSync, users must first ensure they have the latest version installed. The ZKSync network can be added manually by navigating to MetaMask settings, selecting “Networks,” and clicking “Add Network.” Enter the following ZKSync Era network details: Network Name (ZKSync Era Mainnet), RPC URL (available from the official ZKSync documentation), Chain ID (324), Currency Symbol (ETH), and Block Explorer URL (explorer.zksync.io).

Alternatively, many ZKSync-based applications offer automatic network addition through a simple confirmation prompt when users first connect their wallet. For traders prioritizing security, hardware wallet integration provides the same Layer 2 benefits while maintaining private key isolation. The setup process for hardware wallets follows the same network addition steps but requires transaction confirmation on the physical device.

Once configured, the wallet displays ZKSync as a selectable network alongside Ethereum Mainnet and other networks. Users can switch between networks to view their balances on each layer. It’s important to note that assets on Ethereum Layer 1 and ZKSync Layer 2 are tracked separately—ETH on Ethereum Mainnet will not appear in the ZKSync network view until bridged.

Step 2: Depositing Funds into ZKSync

Moving funds from Ethereum Layer 1 to ZKSync requires a deposit transaction through the official ZKSync bridge or through integrated bridge functionality in wallets and applications. The official ZKSync bridge interface (accessible through the ZKSync ecosystem portal) provides the most direct method.

To deposit ETH or ERC-20 tokens, connect your wallet to the bridge interface while on the Ethereum Mainnet network. Select the asset and amount to deposit, then review the transaction details including the one-time Layer 1 gas fee required to process the deposit. This initial deposit transaction occurs on Ethereum Layer 1 and therefore incurs standard Ethereum gas costs, typically ranging from $5 to $50 depending on network congestion (as of 2026-06-17).

After confirming the transaction, the deposit typically completes within 15-30 minutes as the transaction is confirmed on Ethereum and the corresponding funds are credited to your ZKSync address. The bridge maintains a 1:1 representation of assets—depositing 1 ETH on Layer 1 results in 1 ETH on ZKSync Layer 2. Users can verify their ZKSync balance by switching their wallet to the ZKSync network.

For traders planning multiple transactions, depositing a larger amount initially minimizes the relative impact of the one-time Layer 1 deposit fee. For example, depositing $1,000 worth of assets with a $20 gas fee represents a 2% cost, while depositing $100 with the same fee represents 20%. Once funds are on ZKSync, subsequent transactions cost a fraction of a cent, making the initial deposit fee negligible for active users.

Step 3: Conducting Transactions on ZKSync

With funds deposited on ZKSync, users can interact with ZKSync-native applications including decentralized exchanges, lending protocols, NFT marketplaces, and payment applications. Transaction execution on ZKSync follows the same pattern as Ethereum Layer 1 but with dramatically reduced costs and faster confirmation.

To execute a token swap on a ZKSync-based DEX like Syncswap or Mute, connect your wallet (ensuring the ZKSync network is selected), navigate to the swap interface, select the tokens and amount, and confirm the transaction. The wallet displays the estimated gas fee, typically $0.01-0.10 depending on transaction complexity and network activity (as of 2026-06-17). After confirmation, the transaction processes within seconds, with the new token balance immediately reflected in the wallet.

For more complex operations like providing liquidity, staking, or NFT purchases, the process remains similar. Each transaction requires a small gas fee paid in ETH on ZKSync. Users must maintain a small ETH balance on ZKSync to pay for gas—even when transacting with other tokens. A balance of 0.01-0.05 ETH typically covers hundreds of transactions.

Transaction history can be viewed through the ZKSync block explorer (explorer.zksync.io) by entering your wallet address. The explorer displays all deposits, transfers, swaps, and smart contract interactions with transaction hashes, timestamps, gas costs, and status. This transparency allows traders to verify execution and track their ZKSync activity independently of wallet interfaces.

Step 4: Withdrawing Funds Back to Ethereum

Withdrawing assets from ZKSync to Ethereum Layer 1 involves initiating a withdrawal through the ZKSync bridge or through application-specific withdrawal interfaces. The withdrawal process differs from deposits due to the zero-knowledge proof verification requirement.

To withdraw, connect your wallet to the bridge interface while on the ZKSync network, select the asset and amount to withdraw, and confirm the transaction. The withdrawal transaction on ZKSync costs minimal gas (typically under $0.10 as of 2026-06-17). However, the funds do not immediately appear on Ethereum Layer 1. ZKSync batches withdrawals and submits proof to Ethereum periodically, typically every few hours.

After the proof containing your withdrawal is submitted and verified on Ethereum, the funds become available for claim. Users must then execute a final claim transaction on Ethereum Layer 1, which incurs standard Ethereum gas costs. This two-step process (withdraw on ZKSync, claim on Ethereum) is necessary because the withdrawal must be cryptographically proven to Ethereum’s smart contract before funds can be released.

The total withdrawal time typically ranges from a few hours to 24 hours depending on proof submission frequency and Ethereum network conditions. For traders who need faster Layer 1 access, some third-party services offer instant withdrawal by providing liquidity in exchange for a small fee, though this introduces additional counterparty risk. For most use cases, the standard withdrawal process provides the most secure and cost-effective option.

What Are the Real-World Applications of ZKSync?

ZKSync’s scalability improvements enable practical use cases that are economically unfeasible on Ethereum Layer 1, particularly for high-frequency or low-value transactions.

DeFi and Decentralized Exchanges

Decentralized finance protocols on ZKSync offer the same functionality as their Layer 1 counterparts—token swaps, lending, borrowing, yield farming—but with transaction costs reduced by 90-100x. This cost reduction makes strategies viable that would be unprofitable on Ethereum Layer 1.

For example, a trader executing a $100 token swap on Ethereum Layer 1 might pay $10-30 in gas fees (as of 2026-06-17), representing 10-30% of the transaction value. The same swap on a ZKSync-based DEX costs $0.05-0.20, reducing fees to 0.05-0.20% of transaction value. This difference makes small-value trading, frequent rebalancing, and active liquidity provision economically rational.

ZKSync hosts several established DeFi protocols including Syncswap (DEX), Mute (DEX and farming), ZigZag (order book DEX), and Velocore (AMM). These platforms support major tokens bridged from Ethereum including USDC, USDT, DAI, WBTC, and various governance tokens. Liquidity on ZKSync DEXs has grown substantially, with several pools exceeding $10 million in total value locked (as of 2026-06-17).

For yield farmers and liquidity providers, ZKSync enables profitable position management that would be cost-prohibitive on Layer 1. Claiming rewards, compounding yields, and rebalancing positions can be performed daily or even more frequently without gas costs consuming returns. This accessibility democratizes DeFi participation, making it viable for users with smaller capital allocations.

NFTs and Gaming

NFT minting, trading, and gaming applications benefit significantly from ZKSync’s low transaction costs. Minting an NFT on Ethereum Layer 1 can cost $20-100 in gas fees, making it economically unfeasible for artists or projects targeting lower price points. On ZKSync, minting costs drop to under $1, enabling new use cases.

Several NFT marketplaces operate on ZKSync, including Mintsquare and Element, supporting both one-time mints and collection launches. The reduced costs make it viable to mint generative art series, gaming items, or utility NFTs without requiring high floor prices to justify minting costs. For collectors, purchasing and trading NFTs on ZKSync eliminates the gas fee barrier that often exceeds the NFT’s value on Layer 1.

Gaming applications particularly benefit from ZKSync’s scalability. Blockchain games require frequent transactions for item transfers, character actions, reward claims, and marketplace interactions. On Ethereum Layer 1, these micro-transactions are economically impossible. ZKSync enables true in-game economies where players can trade items worth $1-10 without gas fees consuming the transaction value.

Projects like zkApes and zkSync-native gaming platforms demonstrate this potential, offering play-to-earn mechanics, item ownership, and marketplace functionality without the cost barriers that limit Layer 1 gaming adoption. As gaming and metaverse applications continue developing, Layer 2 solutions like ZKSync provide the infrastructure necessary for mass-market viability.

Everyday Payments

ZKSync’s low costs and fast confirmation make it suitable for everyday payment use cases including remittances, merchant payments, and peer-to-peer transfers. Sending $50 to another wallet on Ethereum Layer 1 might cost $5-15 in gas, representing 10-30% overhead. On ZKSync, the same transfer costs under $0.10, reducing fees to less than 0.2%.

This cost structure makes cryptocurrency payments competitive with traditional payment rails for the first time. A merchant accepting cryptocurrency payments through ZKSync can receive funds with near-instant confirmation and minimal fees, comparable to credit card processing costs but without chargebacks or intermediary risk.

Payment applications built on ZKSync include zkSync-integrated wallets with payment functionality, merchant payment gateways, and remittance services. For cross-border transfers, ZKSync offers particular advantages—a user can send USDC from one country to another with sub-second confirmation and negligible fees, bypassing traditional banking infrastructure and its associated delays and costs.

The accessibility of ZKSync payments extends cryptocurrency utility beyond speculation and trading into practical everyday use. As more merchants and services integrate ZKSync payment options, the protocol serves as infrastructure for a more accessible and efficient payment system built on Ethereum’s security foundation.

How Does ZKSync Compare With Other Ethereum Layer 2 Solutions?

Ethereum hosts multiple Layer 2 solutions, each with distinct technical approaches and trade-offs. Understanding these differences helps traders and users select the most appropriate platform for their needs.

Comparison Table: ZKSync vs. Other Layer 2 Solutions

Note: Data reflects approximate values as of 2026-06-17 and may vary with network conditions.

Optimistic rollups (Optimism and Arbitrum) achieve scalability by assuming transactions are valid by default, with a challenge period allowing fraud proofs if invalid transactions are detected. This approach requires a 7-day withdrawal delay to allow time for challenges. Zero-knowledge rollups like ZKSync prove transaction validity cryptographically, eliminating the need for challenge periods and enabling faster withdrawals.

Polygon PoS operates as a sidechain with its own validator set and consensus mechanism, offering fast and cheap transactions but with different security assumptions than Ethereum Layer 2 solutions. Polygon’s security depends on its validator set rather than Ethereum’s consensus, representing a trade-off between independence and security inheritance.

For traders prioritizing capital efficiency, the withdrawal time difference matters significantly. Optimistic rollup users must wait 7 days to withdraw funds to Layer 1, locking capital during this period. ZKSync users can complete withdrawals within hours, providing greater flexibility for moving funds between Layer 2 and Layer 1 or between different protocols.

Why ZKSync Stands Out

ZKSync’s zero-knowledge rollup architecture provides distinct advantages in security, capital efficiency, and long-term scalability. The validity proof mechanism offers mathematical certainty that all transactions are correct, unlike optimistic rollups which rely on economic incentives and challenge periods to detect fraud.

The shorter withdrawal time on ZKSync improves capital efficiency for traders who need to move funds between layers or protocols. A trader can move funds from ZKSync to Ethereum Layer 1 within hours to access a Layer 1 protocol or bridge to another chain, while an Optimism or Arbitrum user faces a 7-day lockup period.

ZKSync’s zkEVM implementation enables Ethereum smart contract compatibility, allowing developers to deploy existing Solidity contracts with minimal modifications. This compatibility has accelerated ecosystem growth, with many established DeFi protocols launching ZKSync versions of their applications.

The zero-knowledge proof technology also provides a foundation for future privacy features. While current implementations focus on scalability, the same cryptographic primitives can be extended to enable private transactions, giving ZKSync a potential advantage in privacy-focused applications as regulatory frameworks evolve.

From a practical trading perspective, ZKSync offers an optimal balance of low costs, fast execution, reasonable withdrawal times, and Ethereum security inheritance. The growing ecosystem of DeFi applications, NFT platforms, and payment services makes ZKSync increasingly viable as a primary execution layer for users who want to minimize costs without compromising security.

Common Mistakes Traders Make With ZKSync

Understanding common errors helps users avoid costly mistakes when transitioning from Ethereum Layer 1 to ZKSync Layer 2.

Insufficient ETH for Gas: Users frequently deposit only the tokens they plan to trade without maintaining an ETH balance for gas fees. While ZKSync gas costs are minimal, every transaction requires a small ETH payment. Users who deposit only USDC or other tokens without ETH cannot execute transactions until they bridge additional ETH. Maintaining 0.01-0.05 ETH covers hundreds of transactions.

Wrong Network Selection: Sending funds to an Ethereum Layer 1 address while connected to the ZKSync network, or vice versa, results in failed transactions or lost funds. Always verify the wallet is connected to the correct network before initiating transfers. Most wallets display the active network prominently, but users must consciously check before each transaction.

Underestimating Deposit Costs: While ZKSync transactions are cheap, the initial deposit from Layer 1 to Layer 2 incurs full Ethereum gas costs. Users depositing small amounts may find the deposit fee represents a significant percentage of their deposit. Planning larger deposits or timing deposits during low-gas periods minimizes this relative cost.

Ignoring Withdrawal Times: Users expecting instant withdrawals from ZKSync to Ethereum Layer 1 may be surprised by the 3-24 hour processing time. Trading strategies that require rapid movement between layers must account for this delay. For time-sensitive needs, maintaining separate balances on both layers or using instant withdrawal services (with associated fees) provides flexibility.

Overlooking Token Availability: Not all tokens available on Ethereum Layer 1 are bridged to ZKSync. Users planning to trade specific tokens should verify they are available on ZKSync before depositing funds. The ZKSync block explorer and bridge interface show supported tokens. Attempting to bridge unsupported tokens may result in lost funds or require manual recovery processes.

Risks and Limitations of ZKSync

While ZKSync offers substantial benefits, users must understand the associated risks and technical limitations.

Smart Contract Risk: ZKSync’s smart contracts on Ethereum Layer 1 and its Layer 2 execution environment represent potential attack surfaces. Although the protocol has undergone multiple audits, smart contract vulnerabilities remain a possibility. A critical bug could potentially freeze funds or enable unauthorized withdrawals. Users should only deposit amounts they can afford to risk and should monitor official communications for security updates.

Bridge Risk: The deposit and withdrawal process involves bridge contracts that hold user funds while they are on Layer 2. These contracts are high-value targets for attackers. While ZKSync’s architecture minimizes bridge risk compared to traditional cross-chain bridges, the contracts still represent a central point of potential failure. The protocol’s security depends on the correctness of both the bridge contracts and the proof verification logic.

Liquidity Limitations: ZKSync’s liquidity, while growing, remains significantly lower than Ethereum Layer 1 or more established Layer 2 solutions like Arbitrum (as of 2026-06-17). Large trades may experience higher slippage on ZKSync DEXs compared to Layer 1. Traders executing substantial positions should verify adequate liquidity exists before depositing large amounts.

Withdrawal Delays: The 3-24 hour withdrawal time, while faster than optimistic rollups, still creates capital inefficiency and timing risk. Users needing immediate Layer 1 access face either waiting for standard withdrawal processing or paying fees for instant withdrawal services. This delay can be problematic during periods of high volatility or when responding to time-sensitive opportunities.

Ecosystem Maturity: ZKSync’s ecosystem, though expanding, offers fewer applications and integrations than Ethereum Layer 1 or more established Layer 2 solutions. Users may find that specific protocols, tokens, or services they rely on are not yet available on ZKSync. This limitation requires users to maintain presence on multiple layers or chains, fragmenting liquidity and complicating portfolio management.

Regulatory Uncertainty: Layer 2 solutions exist in a regulatory gray area in many jurisdictions. Future regulatory frameworks may impose requirements on Layer 2 protocols, bridge operators, or users that affect accessibility or usability. Users in jurisdictions with restrictive cryptocurrency regulations should consider potential compliance implications.

FAQ

What is the difference between Layer 1 and Layer 2 solutions?

Layer 1 refers to the base blockchain (Ethereum) where all transactions are validated by the entire network through consensus. Layer 2 solutions process transactions off-chain and submit proofs or summaries to Layer 1, achieving higher throughput and lower costs while inheriting Layer 1 security. Layer 1 provides security and settlement, while Layer 2 provides scalability and efficiency. Users maintain self-custody on both layers, but Layer 2 requires bridging assets through smart contracts.

Are there any risks to using ZKSync?

Yes, ZKSync carries smart contract risk, bridge risk, and liquidity limitations. The protocol’s smart contracts could contain vulnerabilities despite audits, potentially affecting fund security. Bridge contracts represent high-value targets for attackers. Liquidity on ZKSync remains lower than Layer 1, potentially causing slippage on large trades. Withdrawal delays create timing risk, and regulatory uncertainty may affect future accessibility. Users should only deposit amounts they can afford to risk and should monitor official communications for security updates.

Can I use ZKSync with any Ethereum wallet?

ZKSync supports most popular Ethereum wallets including MetaMask, WalletConnect-compatible wallets, Argent, and hardware wallets like Ledger and Trezor. Users must manually add the ZKSync network to their wallet or confirm automatic network addition when prompted by ZKSync applications. The same wallet address works across Ethereum Layer 1 and ZKSync Layer 2, but assets on each layer are tracked separately. Users must switch networks in their wallet to view and access funds on different layers.

Does ZKSync support all Ethereum tokens?

No, ZKSync supports a growing but limited set of tokens that have been bridged from Ethereum Layer 1. Major tokens including ETH, USDC, USDT, DAI, WBTC, and many governance tokens are available. Users can check supported tokens through the official ZKSync bridge interface or block explorer before attempting to deposit. Attempting to bridge unsupported tokens may result in lost funds or require manual recovery. The supported token list expands as projects deploy bridges and as ecosystem adoption grows.

How does ZKSync ensure security?

ZKSync ensures security through zero-knowledge validity proofs submitted to Ethereum Layer 1. Every batch of transactions is accompanied by a cryptographic proof that mathematically guarantees all state transitions are valid according to protocol rules. Ethereum’s smart contract verifies these proofs before accepting state updates. This means ZKSync inherits Ethereum’s security—if a proof is accepted on Ethereum, the transactions it represents are as secure as any Ethereum transaction. Users maintain self-custody through cryptographic key control, and withdrawal rights are enforced by Ethereum smart contracts.

How long does it take to withdraw from ZKSync to Ethereum?

Standard withdrawals from ZKSync to Ethereum Layer 1 typically complete within 3-24 hours. The process involves two steps: initiating the withdrawal on ZKSync (costs under $0.10 in gas as of 2026-06-17), then claiming the funds on Ethereum after the proof is verified (costs standard Ethereum gas). ZKSync batches withdrawals and submits proofs periodically, creating variable timing. Some third-party services offer instant withdrawals by providing liquidity in exchange for a fee, though this introduces counterparty risk. The withdrawal time is significantly faster than the 7-day delay required by optimistic rollups.
