 # Need to switch to our own fork of tendermint and tendermint-rpc due to event attribute value being nullable.
 # Can switch back once https://github.com/informalsystems/tendermint-rs/issues/1216 is resolved.
 # The fix for the issue is at https://github.com/axelarnetwork/tendermint-rs/commit/e97033e20e660a7e707ea86db174ec047bbba50d.
