@trezor/utxo-lib

Javascript Bitcoin and Bitcoin-like altcoins library for node.js and browsers.

This library is a fork of the bitcoinjs-lib and it is profiled to work with Trezor environment.

It enables standard operations such as generating addresses, creating transactions, importing/exporting keys etc.

Not all the modules/methods from the upstream are present here (like ecpair, psbt...) since we didn't use them for now, however they might be easily added in the future.

You probably don't want to use this package directly. Try one of the alternatives instead:

• bitcoinjs-lib
• @bitgo/utxo-lib
• bcoin
• bitcore

History timeline

This is the fifth and hopefully the ultimate attempt to fork and maintain bitcoinjs-lib.

1. https://www.npmjs.com/package/bitcoinjs-lib-zcash
2. https://github.com/trezor/bitcoinjs-trezor
3. https://github.com/BitGo/bitgo-utxo-lib
4. https://github.com/trezor/trezor-utxo-lib

Main differences

Differences are explicitly described in each file.

• Transaction class is extended by each custom altcoin implementation.
• Transaction class is parsing amounts as strings.
• address module uses different encoding for Decred and handles Bitcoin Cash addresses.
• added coinselect and compose modules (origin source: https://github.com/trezor/hd-wallet/tree/master/src/build-tx)
• removed unused modules: block, classify, ecpair, psbt.

Publishing

This package is published to the npm registry because it is a dependency of @trezor/connect which can be installed as a standalone package.
