tension of ERC20 to support Compound-like voting and delegation.

NOTE: If exact COMP compatibility is required, use the {ERC20VotesComp} variant of this module. This extension keeps a history (checkpoints) of each account's vote power. Vote power can be delegated either by calling the {delegate} function directly, or by providing a signature to be used with {delegateBySig}. Voting power can be queried through the public accessors {getVotes} and {getPastVotes}. By default, token balance does not account for voting power. This makes transfers cheaper.

Vote power can be delegated either\n by calling the {delegate} function directly, or by providing a signature to be used with {delegateBySig}. Voting\n power can be queried through the public accessors {getVotes} and {getPastVotes}.\n By default, token balance does not account for voting power. This makes transfers cheaper. The downside is that it\n requires users to delegate to themselves in order to activate checkpoints and have their voting power tracked.\n _Available since v4.2._" }, "fullyImplemented": false, "id":

Voting power can be queried through the public accessors {getVotes} and {getPastVotes}. By default, token balance does not account for voting power. This makes transfers cheaper.
