Truffle is a development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier. With Truffle, you get:
- Built-in smart contract compilation, linking, deployment and binary management.
- Automated contract testing with Mocha and Chai.
- Configurable build pipeline with support for custom build processes.
- Scriptable deployment & migrations framework.
- Network management for deploying to many public & private networks.
- Interactive console for direct contract communication.
- An instant rebuilding of assets during development.
- External script runner that executes scripts within a Truffle environment.

This library supports Synchronized transactions for better control flow (i.e., transactions won’t finish until you’re guaranteed they’ve been mined). It also supports “Promises” and works well with
async/await. It provides default values for transactions, like
from address or
gas. The library returns logs, transaction receipt and transaction hash of every synchronized transaction.

Created by the Zeppelin team, 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.

Linting is the process of checking the source code for Programmatic as well as Stylistic errors. This is most helpful in identifying some common and uncommon mistakes that are made during coding.[source]
Ethlint analyzes your Solidity code for style & security issues, and fixes them. Standardize Smart Contract practices across your organization. Integrate with your build system. Deploy with confidence! Solium does not strictly follow Solidity Style Guide. The practices it enforces by default are best practices for the community at large.

Embark is a framework that allows you to easily develop and deploy Decentralized Applications (DApps). A Decentralized Application is a serverless html5 application that uses one or more decentralized technologies. Embark currently integrates with EVM blockchains (Ethereum), Decentralized Storages (IPFS), and Decentralized communication platforms (Whisper and Orbit). Swarm is supported for deployment.
