New Features
Rate Limiting Middleware
This release adds the IBC rate-limiting middleware, migrated from ibc-apps. It applies configurable per-channel, per-denomination quotas to ICS-20 transfers and supports both IBC v1 and IBC v2.
The middleware tracks packet flow across sends, receives, acknowledgements, timeouts, and asynchronous acknowledgements to ensure accurate quota accounting. Rate limits can be managed through governance, queried over gRPC and CLI, and are initialized through genesis.
