The relayer supports the following:
- creating IBC connections
- creating IBC transfer channels.
- initiating a cross chain transfer
- relaying a cross chain transfer transaction, its acknowledgement, and timeouts
- relaying from state
- relaying from streaming events
- sending an UpgradePlan proposal for an IBC breaking upgrade
- upgrading clients after a counter-party chain has performed an upgrade for IBC breaking changes
- fetching canonical chain and path metadata from the GitHub repo to quickly bootstrap a relayer instance
- compatible with the icq module and can query a target chain free of charge apart from intial IBC connection tx fees
The relayer currently cannot:
- create clients with user chosen parameters (such as UpgradePath)
- submit IBC client unfreezing proposals
- monitor and submit misbehavior for clients
- use IBC light clients other than Tendermint such as Solo Machine
- connect to chains which don't implement/enable IBC
- connect to chains using a different IBC implementation (chains not using SDK's
x/ibcmodule)
