Any program that runs on the Ethereum Virtual Machine (EVM) is commonly referred to as a “smart contract”. The most popular languages for writing smart contracts on Ethereum are Solidity and Vyper, though there are others under development.

* Solidity is the most popular language on Ethereum, inspired by C++, Python, and Javascript

* Vyper is a security-focused language for Ethereum, based on Python.

Ethereum has a large and growing number of tools to help developers build, test, and deploy their applications. Below are the most popular tools to get you started. If you want to dive deeper, check out this comprehensive list.

* Truffle is a development environment, testing framework, build pipeline, and other tools.

* Embark is a development environment, testing framework, and other tools integrated with Ethereum, IPFS, and Whisper.

Waffle is a framework for advanced smart contract development and testing (based on ethers.js).

Etherlime is an Ethers.js based framework for dapp development (Solidity & Vyper), deployment, debugging, testing and more.

Block explorers are services that let you browse the Ethereum blockchain (and its testnets), by finding information about specific transactions, blocks, contracts, and other on-chain activity.

The Ethereum community maintains multiple testnets. These are used by developers to test their applications under different conditions before deploying to the Ethereum mainnet.

Goerli Cross-client Proof of Authority blockchain, built and maintained by the Goerli community

The Ethereum network is made up of many nodes who run compatible client software. The majority of these nodes run Geth or Parity, each of which can be configured in different ways according to your needs.

Parity Ethereum client written in Rust

Pantheon Ethereum client written in Java

Ethnode Run an Ethereum node (Geth or Parity) for local development.

The Ethereum community has adopted many standards that are helpful to developers. Typically these are introduced as Ethereum Improvement Proposals (EIPs), which are discussed by community members through a standard process.

Certain EIPs relate to application-level standards (e.g. a standard smart-contract format), which are introduced as Ethereum Requests for Comment (ERC). Many ERCs are critical standards used widely across the Ethereum ecosystem.
