Embedded Crosschain Actions

For developers wanting to enable users to seamlessly interact with your dApp or chain using assets from other chains, this guide provides technical instructions for bundling a bridge with user actions.

This solution is a great fit for apps on a single-chain or that want to expose core actions that users can execute with funds on other chains. It is a future-forward solution that aims to abstract bridging from end-users by making crosschain actions so fast and cheap that it feels like a single-chain experience.

The Crosschain Actions Integration Guidecontains technical instructions for bundling a bridge with user actions. The integration process is simple and consists of three steps:

1. Craft the message that is the set of transactions to execute on the destination

2. Request quotes from Across API Reference API, passing in the message parameter defined above

3. Initiate a deposit by using data returned from Across API to call functions on Across smart contracts, specifying a message (set of transactions to execute on the destination)
