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. As a relatively young language, Solidity is advancing at a rapid speed. We aim for a regular (non-breaking) release every 2-3 weeks, with approximately two breaking releases per year. ...

...Import and export JSON wallets (Geth, Parity and crowdsale) Import and export BIP 39 mnemonic phrases (12 word backup phrases) and HD Wallets (English as well as Czech, French, Italian, Japanese, Korean, Simplified Chinese, Spanish, Traditional Chinese. Meta-classes create JavaScript objects from any contract ABI, including ABIv2 and Human-Readable ABI. Connect to Ethereum nodes over JSON-RPC, INFURA, Etherscan, Alchemy, Ankr or MetaMask. ENS names are first-class citizens; they can be used anywhere an Ethereum addresses can be used. Tiny (~104kb compressed; 322kb uncompressed). Modular packages; include only what you need. Complete functionality for all your Ethereum desires. ...

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. Powered by Slither to extract useful information before the fuzzing campaign. ...

fuels-rs is a Rust-native Software Development Kit (SDK) for the Fuel blockchain. It facilitates compilation, deployment, transaction crafting, contract interaction, and testing of Sway smart contracts, as well as launching and controlling local Fuel nodes for development or CI workflows.

...Nethereum is developed targeting netstandard 1.1, netstandard 2.0, netcore 2.1, netcore 3.1, net451 and also as a portable library, hence it is compatible with all the operating systems (Windows, Linux, MacOS, Android, and OSX) and has been tested on cloud, mobile, desktop, Xbox, hololens and windows IoT. Simplified smart contract interaction for deployment, function calling, transaction and event filtering and decoding of topics. ABI to .Net type encoding and decoding, including attribute-based for complex object deserialization. Transaction, RLP, and message signing, verification, and recovery of accounts. The simplified account life cycle for both managed by third-party client (personal) or stand-alone (signed transactions).

...This wastes time and might introduce bugs that will be triggered only in runtime. TypeChain solves these problems (as long as you use TypeScript). TypeChain is a code generator - provide ABI file and name of your blockchain access library (ethers/truffle/web3.js) and you will get TypeScript typings compatible with a given library.

...Visit our developer portal for a comprehensive list of core & community-maintained packages. All packages maintained with this monorepo are listed. You will also need to have Python 3 installed, in order to build and run the tests of abi-gen's command-line interface, which is integrated with the yarn build, yarn test, and yarn lint commands described below. More specifically, your local pip should resolve to the Python 3 version of pip, not a Python 2.x version.
