OpenZeppelin - A Framework to build secure smart contracts on Ethereum

  •        262

OpenZeppelin is a library for writing secure Smart Contracts on Ethereum. With OpenZeppelin, you can build distributed applications, protocols and organizations. It is meant to provide secure, tested and audited code to enable the new generation of distributed applications, protocols and organizations. OpenZeppelin is a community effort to reduce the hurdle to develop and use them.

openzeppelin-solidity - OpenZeppelin is a library for secure smart contract development

  •    Javascript

OpenZeppelin is a library for secure smart contract development. It provides implementations of standards like ERC20 and ERC721 which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems. To write your custom contracts, import ours and extend them through inheritance.

Solidity - The Solidity Contract-Oriented Programming Language

  •    C++

Solidity is a contract-oriented, high-level language for implementing smart contracts. It was influenced by C++, Python and JavaScript and is designed to target the Ethereum Virtual Machine (EVM). It is statically typed, supports inheritance, libraries and complex user-defined types among other features. With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets.

mythril-classic - Mythril Classic: Security analysis tool for Ethereum smart contracts

  •    Python

Mythril Classic is an open-source security analysis tool for Ethereum smart contracts. It uses concolic analysis, taint analysis and control flow checking to detect a variety of security vulnerabilities. If you a smart contract developer who wants convenience and comprehensive results, you should be using MythX, our next-gen smart contract security API that integrates with Truffle Framework and other development environments.

porosity - *UNMAINTAINED* Decompiler and Security Analysis tool for Blockchain-based Ethereum Smart-Contracts

  •    C++

Ethereum is gaining a significant popularity in the blockchain community, mainly due to fact that it is design in a way that enables developers to write decentralized applications (Dapps) and smart-contract using blockchain technology. Ethereum blockchain is a consensus-based globally executed virtual machine, also referred as Ethereum Virtual Machine (EVM) by implemented its own micro-kernel supporting a handful number of instructions, its own stack, memory and storage. This enables the radical new concept of distributed applications.
