Introduction
Connext provides the simplest possible experience for building xchain applications (xApps).
Building a xApp requires only two straightforward steps:
- 1.Implement
xReceive
in the destination chain contract. This is the function that receives the payload you pass across chains. - 2.Call
xcall
on the origin chain, passing in your payload and relayer fees.
