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

When traders hold funds outside the chain or asset your DEX accepts, a separate bridge journey can interrupt the path to the first trade. This guide explains how an app-native Deposit Widget or SDK can connect cross-chain funding directly to the user’s trading balance.

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

Choose the integration surface

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.

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.

Integrate Avail Deposits

BUILD WITH AVAIL DEPOSITS

Use the Deposit Widget for a faster integration. Embed a configurable, app-native interface for users to select eligible funds, review the destination and complete the deposit without leaving your app.

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.
