This is a collection of libraries and utilities for Ethereum.

Use cases

Creating an online wallet?

Check out keythereum for managing keys and ethereumjs-tx for creating transactions with them.

Creating a Dapp?

You will need to interface with the Ethereum network. web3.js provides a complete RPC interface from Javascript. If looking for a more lightweight option, ethereumjs-abi or solidity.js can handle the ABI encoding.

Interested in running a node?

See node-blockchain-server. It is in a pretty rough state at the moment, but at least can download the blockchain.

Ethereum JS projects not tracked here

• web3.js: the complete API as seen in the wiki
• solidity.js: ABI encoding and decoding (the relevant code split out from web3.js)
