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. Powered by Slither to extract useful information before the fuzzing campaign. Source code integration to identify which lines are covered after the fuzzing campaign. Curses-based retro UI, text-only or JSON output. -

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. 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. You can follow the implementation status of new features in the Solidity Github project. You can see the upcoming changes for the next breaking release by switching from the default branch (develop) to the breaking branch. -

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. Reduce the risk of vulnerabilities in your applications by using standard, tested, community-reviewed code. -

Neoblog
Neoblog is a public blogging platform that's completely serverless
Neoblog is a public blogging platform that's completely serverless. Reading and posting articles to our platform require no servers and runs completely on the NEO Blockchain and IPFS. The traditional way of setting up a blog is to set up a server that will store your content. With modern technologies, we are advancing into an age that moves away from traditional servers. Combine this with the decentralization of storage (IPFS) and blockchain, we now have a toolkit to provide an application that's completely serverless. Neoblog is a serverless application that uses these these technologies: built on the NEO blockchain, articles are posted to our smart contract, while the content is stored on IPFS. -

TypeChain
TypeScript bindings for Ethereum smart contracts
TypeChain generates only TypeScript typings (d.ts) files, if you're looking for "opinionated", "batteries included" solution check out our new project: eth-sdk. It generates typesafe, ready to use ethers.js wrappers and uses etherscan/sourcify to automatically get ABIs based only on smart contract addresses. Under the hood, eth-sdk relies on TypeChain. Interacting with blockchain in Javascript is a pain. Developers need to remember not only a name of a given smart contract method or event but also it's full signature. 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. -

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. zkSNARKs are the most widely used zero-knowledge protocols, with the anonymous cryptocurrency Zcash and the smart-contract platform Ethereum among the notable early adopters. Ethereum runs computations on all nodes of the network, resulting in high costs, limits in complexity, and low privacy. zkSNARKs have been enabling to only verify computations on-chain for a fraction of the cost of running them, but are hard to grasp and work with. -

BOOM POOL
A new type of utility token with self-destructing mechanism
BOOM is a new type of utility token with self-destructing mechanism, based on Ethereum smart contract. BOOM project is a social experiment, aiming at exploring the market influence of an extremely deflationary cryptocurrency, and it will validate the effect of BOOM token as a hedge against the rapid inflation in token ecosystem. The origin of BOOM is simple, once users transfer BOOM to others, 1% of the total transfer amount is automatically destroyed at the same time. The initial total supply of BOOM is 1 billion. The supply will decrease due to transactions, and no new BOOM will be issued then. The destruction of BOOM token will run automatically on chain, written in Ethereum smart contract. No one can interfere. When taking insight into bitcoin and litecoin supply halving history, you can find that destroying the liquidity can cause positive market expectations, and may cause a value increase. Now Boom provides a whole new supply curve, which is much more radical. -

BlockScout
Blockchain explorer for Ethereum based network
Blockscout provides a comprehensive, easy-to-use interface for users to view, confirm, and inspect transactions on EVM (Ethereum Virtual Machine) blockchains. 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. -

Cy
Hackers terminal browser of Cyber blockchains
Cy - a nushell wrapper, a client for the Cyber family blockchains (bostrom, pussy) and IPFS. Bostrom is the name of the consensus computer that maintains a general-purpose, permissionless informational graph where nodes are CIDs of files in the IPFS network, and edges are Cyberlinks (consisting of source, destination, author, height - records) written into the blockchain. The information written into the blockchain is secured to remain in existence as long as the blockchain is operative. The blockchain is designed with economic incentives that motivate validators to sustain the network. For further information about Cyber blockchains, please refer to Bostrom Journal. -
