Summary

Different types of end users:
  • CLI users who want to manually incentivize IBC packets
  • Client developers
The Fee Middleware module allows end users to add a ‘tip’ to each IBC packet which will incentivize relayer operators to relay packets between chains. gRPC endpoints are exposed for client developers as well as a simple CLI for manually incentivizing IBC packets.
