# EXA

The EXA smart contract encapsulates the functionality of the EXA ERC20 token. This smart contract uses OpenZeppelin's [`ERC20VotesUpgradeable`](https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/blob/master/contracts/token/ERC20/extensions/ERC20VotesUpgradeable.sol) implementation.
