-There is an open [PR](https://github.com/cosmos/ibc-go/pull/208) that implements support for Wasm-based light clients, but it needs to be updated after the finalization of the [ICS28](https://github.com/cosmos/ibc/tree/master/spec/client/ics-008-wasm-client) specification. The PR will also need a final review from ibc-go core team members.

This is basically adding a new proof spec that will be used during connection handshake with a chain that has migrated to SMT to verify that the light client of the counterparty chain uses the correct proof specs to be able to verify proofs for that chain.
