solidity-utils is a utility package for the development of smart contracts written in Solidity. It includes useful contracts, interfaces and libraries, bringing some test tools as well.

Contracts

  • Dust Collector: collects small amounts of leftover tokens or ETH (also known as "dust") and transfers them to a designated recipient.

  • Governable: provides a mechanism for managing a governor role, which has the authority to administrate the contract.

  • OnlyEOA: validates whether a caller is an externally owned account (EOA) or not.

  • Pausable: provides pausable functionalities to a given contract.

  • Roles: manages roles for interactions with a smart contract, leveraging OpenZeppelin's AccessControl.

Interfaces

  • IBaseErrors: provides a set of custom error messages that helps to catch and handle errors that may occur during contract execution.

Libraries

  • Create2Address: deterministically computes a contract address using the Create2 opcode.

Test

  • DSTestPlus: includes utility functions for measuring gas consumption, labeling addresses, mocking contracts, simulating time, computing a contract address using Create2, and more. It extends the DSTest contract.
