zkSync Bridge: how to bridge to and from zkSync
zkSync is a zero-knowledge rollup on Ethereum. Its official bridge relies on validity proofs, so withdrawals finish once a proof is accepted on Ethereum, usually within hours rather than a week. Fast bridges still deliver sooner.
Quick answer
Services supporting zkSync: 8. Most used in our guides: ZKsync Portal, Across, Relay, Bungee. Direct transfers possible to: Ethereum, Bitcoin, Solana, BNB Chain, Arbitrum, Base, TRON, Hyperliquid.
Popular services
ZKsync PortalCanonical bridge
Official zkSync bridge: the network's own route to and from Ethereum. Slower to withdraw, but no extra parties to trust.
Across
Across moves coins between Ethereum, its layer 2 networks and several other chains, usually in seconds. You send funds on one network, and an independent relayer pays you on the other side from its own money. The relayer gets paid back later, so you do not have to wait.
Relay
Relay moves and swaps coins between networks, usually in seconds. You say what you want, and a solver pays you on the destination network right away from its own funds. The solver settles up with Relay afterwards.
Bungee
Bungee is an aggregator made by the Socket team. It compares bridges between Ethereum-style networks and shows you the options side by side.

Alternative ways to move funds
The official rollup bridge
The bridge run by zkSync itself relies only on Ethereum and the rollup. It is the safest option, but withdrawals to Ethereum are slower than with third-party bridges.
Move stablecoins instead
Converting to USDC or USDT and moving it through the issuer’s own transfer protocol often has the widest coverage and the least slippage. Swap back on the destination if you need another asset.
Through a centralised exchange
Deposit on zkSync, trade if needed, and withdraw on the destination network. Simple and often cheap, but the exchange holds your funds in between and needs identity verification.
Two steps through a well-connected chain
If no single route exists, first move to a chain with many connections (Ethereum, Solana or a major rollup), then on to the destination. It costs two fees, but each step uses a well-tested route.
How transfers work on zkSync
- The official bridge is the most trust-minimised route to and from Ethereum.
- Liquidity bridges and intent networks cover most rollup-to-rollup routes in minutes.
- Stablecoins can move through issuer transfer protocols where zkSync is supported.
What to watch out for
- Proof and finalisation times vary between rollups and can grow during busy periods.
- Smaller rollups are supported by fewer bridges, so compare quotes before you send.

Frequently asked questions
How can I bridge from zkSync?
8 of the projects we review support zkSync, including Across, Bungee, Relay. We have 2 route guides that involve zkSync.
Which major chains can I reach from zkSync directly?
Directly: Ethereum, Bitcoin, Solana, BNB Chain, Arbitrum, Base, TRON, Hyperliquid. Other destinations need two steps or an exchange.
What if there is no bridge for my zkSync route?
Use a centralised exchange, take two steps through a well-connected chain such as Ethereum or Solana, or move a stablecoin instead and swap on arrival.
