How Synapse Bridge moves a swap across chains
Synapse Bridge keeps the flow direct: your wallet starts the transfer, the app shows the live route, and your confirmation sends the transaction on-chain.
Connect your wallet
Open the app with a self-custody wallet. You stay in control of approvals and signatures from the first step.
Choose route and asset
Select the source chain, destination chain and supported asset. Use ETH, USDC or another listed token when that route is available in the app.
Review and confirm
Check the quoted output, timing, route and network cost, then sign only if the transaction matches what you want to do.
A sharper way to bridge without leaving self-custody
Bridge from your wallet, not an account
Synapse Bridge is built for users who want cross-chain access without creating an exchange account. Keep custody in a wallet such as MetaMask, review each approval and sign the final transfer yourself.

Useful chain coverage
Move between Ethereum and popular EVM ecosystems from one interface, with supported routes and assets shown in the live app.
Live costs before action
Bridge pricing depends on liquidity, route design and gas. The app gives you the current quote before you confirm.
Clear confirmation flow
See what you are sending, where it is going and what the wallet asks you to approve before funds move.
Supported routes show live in the app
Synapse Bridge is designed for cross-chain DeFi users moving between Ethereum, L2 networks and other EVM chains tracked across the broader bridge market. Assets such as ETH and USDC appear when the selected route supports them.

01What is Synapse Bridge?
Synapse Bridge is a non-custodial DeFi bridge and swap app for moving supported assets across chains. You connect a wallet, choose a route and sign the transfer yourself.
02Is Synapse Bridge non-custodial?
Yes. You keep the private keys, approvals and transaction signatures in your wallet. The app gives you a bridge route, but it does not create a custodial account for your funds.
03Which chains and assets can I bridge?
Available routes depend on live app support. Ethereum, L2 ecosystems and EVM networks are typical bridge destinations; see the supported chains page before planning a transfer.
04How long does a bridge transfer take?
Time depends on the selected networks, confirmation conditions and route. Synapse Bridge shows the current estimate in the app before you sign.
05What does Synapse Bridge cost?
The final cost depends on the route and on-chain fees such as Ethereum gas. Review the live quote and wallet prompt before confirming.
06How should I think about safety?
Use the app from the correct URL, inspect the wallet request, avoid blind approvals and understand bridge risk. Independent dashboards such as L2Beat network research can help you compare chain assumptions.
