Bridging assets to zkSync Era has become a popular step for users seeking faster, more cost-effective transactions on Ethereum’s Layer 2 ecosystem. With growing adoption, zkSync Era offers scalable infrastructure using zero-knowledge rollup technology, enabling high-throughput and low-fee interactions across decentralized applications (dApps). This guide walks you through the process of transferring digital assets from Ethereum and other supported networks directly to zkSync Era using trusted bridging solutions.
Understanding zkSync Era and Blockchain Bridges
zkSync Era is a Layer 2 scaling solution built to enhance Ethereum’s performance by processing transactions off-chain and submitting cryptographic proofs back to the mainnet. This approach significantly reduces gas fees—averaging just $0.30 per transaction—and accelerates confirmation times. As of mid-2025, zkSync Era supports over 800,000 daily transactions, outpacing even Ethereum on peak days.
To access this network, users must bridge their assets from Ethereum or other chains. Blockchain bridges act as secure conduits, allowing digital assets to move across different networks while preserving ownership and integrity. These bridges use smart contracts, liquidity pools, or message-passing protocols to lock, mint, and release tokens across chains.

Why Bridge to zkSync Era?
- Lower Fees: Save up to 70% on transaction costs compared to Ethereum mainnet.
- Faster Transactions: Benefit from near-instant finality thanks to zk-rollup architecture.
- Growing Ecosystem: Access a rapidly expanding suite of DeFi protocols, NFT marketplaces, and gaming dApps.
- Potential Airdrops: Active users may qualify for future token distributions based on on-chain activity.
Using the Official zkSync Era Bridge
The official zkSync bridge enables seamless transfers between Ethereum (Layer 1) and zkSync Era (Layer 2). It supports major assets like ETH, WETH, USDC, DAI, and more.
How It Works
The bridge operates using two core smart contracts:
- One deployed on Ethereum mainnet.
- One on zkSync Era.
When you deposit:
- Assets are locked in the L1 contract.
- An equivalent amount is minted on zkSync Era.
- Funds appear in your wallet within minutes.
For withdrawals:
- Tokens are burned on zkSync Era.
- The corresponding amount is released from the L1 contract.
- Finalization typically takes 1–2 hours due to Ethereum's block confirmation time.
Step-by-Step: Deposit from Ethereum to zkSync Era
- Go to the zkSync Era Bridge.
- Connect your wallet (e.g., MetaMask) and ensure it’s set to Ethereum Mainnet.
- Select the asset and amount you want to bridge.
- Confirm the receiving address (your connected wallet by default).
- Click Continue, review fees and details, then select Send to zkSync Era.
- Approve the transaction in your wallet.
Once confirmed, your funds will be available on zkSync Era shortly.
Withdrawing from zkSync Era to Ethereum
- Navigate to the Withdraw tab on the same bridge interface.
- Switch your wallet network to zkSync Era.
- Enter withdrawal details—asset, amount, and destination address.
- Click Send to Ethereum Mainnet and confirm the transaction.
Note: Withdrawals require patience due to Ethereum’s finality window.
Alternative Bridging Platforms
While the official bridge is reliable, third-party options offer additional flexibility, multi-chain support, and competitive pricing.

Frequently Asked Questions (FAQ)
Q: Is bridging to zkSync Era safe?
A: Yes, when using reputable bridges like the official zkSync portal, Rhino.fi, or Orbiter Finance. Always verify URLs and avoid phishing sites.
Q: How long does a deposit take?
A: Deposits from Ethereum usually take 5–15 minutes. Withdrawals may take 1–2 hours due to L1 confirmation requirements.
Q: Are there gas fees when bridging?
A: Yes—on Ethereum for deposits; minimal fees apply on zkSync Era for withdrawals and swaps.
Q: Can I bridge stablecoins like USDC or USDT?
A: Yes, both are supported on most bridges including the official zkSync bridge and third-party platforms.
