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... -

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... -

ZoKrates
A toolbox for zkSNARKs on Ethereum
ZoKrates is a toolbox for zkSNARKs on Ethereum. It helps you use verifiable computation in your DApp, from the specification of your program in a high-level language to generating proofs of computation to verifying those proofs in Solidity. Zero-knowledge proofs (ZKPs) are a family of probabilistic protocols, first described by Goldwasser, Micali and Rackoff in 1985. One particular family of ZKPs is described as zero-knowledge Succinct Non-interactive ARguments of Knowledge, a.k.a. zkSNARKs.... -
