• bindings/erc20 provides generated code for working with ERC20 contracts
• bindings/oneinch/v2 provides generated code for working with OneInch V2 router contracts
• bindings/oneinch/v3 provides generated code for working with OneInch V3 router contracts
• unicrypt/presalefactory provides generated code for working with UniCrypt presale factories

sushiswap

Wrapper around go-ethereum's ethclient package for using sushiswap v2.

uniswap

Wrapper around go-ethereum's ethclient package for using uniswap v2.

testenv

Provides a wrapper around the SimulatedBackend allowing for an in-memory blockchain. It is particularly useful for local smart contract development, or developing backend dApps.

utils

Provides utility functions including all goethereum book utils, a helper to make bind.TransactOpts safe for concurrent use, as well as a general Blockchain interface that satisfies all functions provided by simulated backend, as well as ethclient which is useful for drop-in replacement of actual RPC clients, and test environments.
