# Developer Resources {#developer-resources}

<div class="featured">Guides, resources, and tools for developers building on Ethereum.</div>

## Getting started {#getting-started}

**If you’re new to developing with Ethereum, you’re in the right place.** These guides written by the Ethereum community will introduce you to the basics of the Ethereum stack and introduce core concepts that might be different from other app development you’re familiar with.

Need a more basic primer first? Check out [ethereum.org/learn.](/learn/)

## Smart Contract Languages {#smart-contract-languages}

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](https://github.com/ConsenSys/ethereum-developer-tools-list#smart-contract-languages).

**Solidity -** ***The most popular language on Ethereum, inspired by C++, Python and JavaScript.***

## Standards {#standards}

The Ethereum community has adopted many standards that are helpful to developers. Typically these are introduced as [Ethereum Improvement Proposals](http://eips.ethereum.org/) (EIPs), which are discussed by community members through a [standard process](http://eips.ethereum.org/EIPS/eip-1).

- [List of EIPs](http://eips.ethereum.org/)
- [EIP github repo](https://github.com/ethereum/EIPs)
- [EIP discussion board](https://ethereum-magicians.org/c/eips)
- [Ethereum Governance Overview](https://blog.bmannconsulting.com/ethereum-governance/) *March 31, 2019 - Boris Mann*
- [Playlist of all Ethereum Core Dev Meetings](https://www.youtube.com/playlist?list=PLaM7G4Llrb7zfMXCZVEXEABT8OSnd4-7w) *(YouTube Playlist)*

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

- [List of ERCs](http://eips.ethereum.org/erc)

- [ERC721 - A standard interface for non-fungible tokens](https://eips.ethereum.org/EIPS/eip-721)
