Embedded Cross-chain 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 cross-chain actions so fast and cheap that it feels like a single-chain experience.

The Cross-chain 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 GET /suggested-fees 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)
