      • ERC777WithoutBalance.sol: Clone of the OpenZeppelin ERC777 contract, but does not store any token balances
      • WadRawMath.sol: Math library copied from Aave repo
    • balancer
      • Balancer777: Receives ERC777 tokens and swaps into destination token using Balancer
      • BalancerHub: Root contract, stores a mapping of tokens to pools, constructs Balancer777s
    • uniswap
      • UniswapWrapper.sol: Receives 777 tokens and swaps into destination token using Uniswap V2
      • UniswapWrapperFactory.sol: Factory for UniswapWrappers
