    OpenZeppelin Contracts

    OpenZeppelin Contracts

    OpenZeppelin Contracts is a library for secure smart contracts

    A library for secure smart contract development. Build on a solid foundation of community-vetted code. OpenZeppelin Contracts uses semantic versioning to communicate backward compatibility of its API and storage layout. To keep your system secure, you should always use the installed code as-is, and neither copy-paste it from online sources nor modify it yourself. The library is designed so that only the contracts and functions you use are deployed, so you don't need to worry about it needlessly increasing gas costs. ...

    Solidity

    Solidity

    The Smart Contract Programming Language

    Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum. Solidity 0.8.4 adds custom structured errors, allows more flexible configuration of the SMTChecker and fixes a bug in the Solidity ABI decoder v2. Read more about the bug here. With v0.8.4, errors can be defined inside and outside of contracts (including interfaces and libraries). This provides a convenient and gas-efficient way to explain to users why an operation failed. ...

    Echidna

    Echidna

    Ethereum smart contract fuzzer

    Echidna is a weird creature that eats bugs and is highly electrosensitive (with apologies to Jacob Stanley) More seriously, Echidna is a Haskell program designed for fuzzing/property-based testing of Ethereum smarts contracts. It uses sophisticated grammar-based fuzzing campaigns based on a contract ABI to falsify user-defined predicates or Solidity assertions. We designed Echidna with modularity in mind, so it can be easily extended to include new mutations or test specific contracts in specific cases. Optional corpus collection, mutation and coverage guidance to find deeper bugs. ...

    BlockScout

    BlockScout

    Blockchain explorer for Ethereum based network

    ...Blockscout currently supports a wide range of projects and hosts chains such as Ethereum, Ethereum Classic, Gnosis Chain, RSK, LUKSO, Astar, and many more. BlockScout is an Elixir application that allows users to search transactions, view accounts and balances, and verify smart contracts on the Ethereum network including all forks and sidechains. Currently available full-featured block explorers (Etherscan, Etherchain, Blockchair) are closed systems which are not independently verifiable. As Ethereum sidechains continue to proliferate in both private and public settings, transparent, open-source tools are needed to analyze and validate transactions.
