A pure JavaScript Bitcoin library for node.js and browsers. Backed by (slowly improving) testing, proven by over a million wallet users. The backbone for almost all Bitcoin web wallets in production today.
This is not the original bitcoinjs-lib that was not updated for a while. The current bitcoinjs-lib has been refactored to clean things up, add new functionality and merge improvements from the community. If you are looking for the original, it will be tagged as 0.1.3. We will use 0.2.x for releases based on these changes, so be sure to use the 0.1.3 tag if you need the original version.
- Bitcoin Testnet and Mainnet (production) support
- HD Wallets
- Highly secure random private key / address generation using window.crypto.getRandomValues
- ECDSA signing and verification
- Transaction creation (pay-to-pubkey-hash), support for multisignature transactions
- A (somewhat incomplete) wallet implementation, improvements ongoing
