Use the Widget for a configurable drop-in interface. Use the SDK when the DEX needs to own the entire presentation, connect deposits to its balance model or trigger a specific action after completion.

How to Add Cross-Chain Deposits to Your DEX in One Integration

Configure the destination

Set the destination chain, preferred destination asset and any app-level constraints. Present only eligible sources and keep the expected received amount visible before confirmation.

Connect completion to the DEX

After a successful deposit, refresh balances and return the user to the relevant trade, market or portfolio state. The deposit should feel like the first step of a trade, not a disconnected utility.

Test the failure states

Test unsupported assets, insufficient balance, wallet rejection, quote expiry, route unavailability, delayed completion and recovery. Give the user a clear next action without forcing them to diagnose the underlying protocol stack.

Ship with measurement

Instrument the journey from deposit opened to first trade. Compare eligible-source selection, quote success, confirmation and trade completion so the team can separate funding friction from trading friction.

Use the Avail SDK for a custom experience. Build the funding journey into your own UI while controlling the destination, user flow and what happens after the deposit completes.
