The <ahref="https://github.com/ethereumjs/">EthereumJS</a> community builds Javascript tools implementing core <ahref="https://ethereum.org">Ethereum</a>
technologies, protocols and APIs for helping developers to interact with the Ethereum network and build
their own applications.
<ahref="https://github.com/ethereumjs/">EthereumJS</a> is an implementation of the core <ahref="https://ethereum.org">Ethereum</a> Execution Layer (EL) Protocol stack in TypeScript.
Check out [keythereum](https://github.com/ethereumjs/keythereum) or [ethereumjs-wallet](https://github.com/ethereumjs/ethereumjs-wallet) (with HD wallet support) for managing keys and [ethereumjs-tx](https://github.com/ethereumjs/ethereumjs-tx) for creating transactions with them.
[ethereumjs-icap](https://github.com/ethereumjs/ethereumjs-icap) might also come handy for dealing with the ICAP (Ethereum in IBAN) format.

You will need to interface with the Ethereum network. [web3.js](https://github.com/ethereum/web3.js) and [ethers.js](https://github.com/ethers-io/ethers.js) both provide a complete Javascript API to interact with the RPC interface. If looking for a more lightweight option, [ethereumjs-abi](https://github.com/ethereumjs/ethereumjs-abi) or [ethjs-abi](https://github.com/ethjs/ethjs-abi) can handle the ABI encoding.

### Build for the Web?
Most of the EthereumJS libraries can be transpiled with [babel](https://babeljs.io/) to be used in web context.
We provide [browser-builds](https://github.com/ethereumjs/browser-builds) for some EthereumJS libraries, be
warned though that these might often be slightly out of date.
