VoteExtensions will allow validators to vote and agree on the oracle price at each block, enabling a more efficient price discovery and liquidation system for the protocol. Aleksandr is an experienced Cosmos developers that will prioritize the development of VoteExtensions to ensure release ahead of the dYdX mainnet. This will allow the integration and testing of VoteExtensions on dYdX v4 ahead of mainnet launch. This grantee will be working closely with the other grant in similar scope.
