This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@trezor/utxo-lib) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@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:

History timeline

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

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.
