Fork of bitcoinjs-message

A TypeScript library for Bitcoin transaction management, based on Bitcoin Descriptors for defining inputs and outputs. It facilitates optimal UTXO selection and transaction size calculation.

This library parses and creates Bitcoin Miniscript Descriptors and generates Partially Signed Bitcoin Transactions (PSBTs). It provides PSBT finalizers and signers for single-signature, BIP32 and Hardware Wallets.

A TypeScript library for retrieving Bitcoin funds from ranged descriptors, leveraging @bitcoinerlab/explorer for standardized access to multiple blockchain explorers.

Bitcoin Blockchain Explorer: Client Interface featuring Esplora and Electrum Implementations.

Bitcoin Miniscript, a high-level language for describing Bitcoin spending conditions. It includes a compiler/analyzer with a signer‑agnostic satisfier that derives symbolic witnesses (e.g., <sig(key)>).

Bitcoin Miniscript policy compiler

A library for performing elliptic curve operations on the secp256k1 curve. It is designed to integrate into the BitcoinJS & BitcoinerLAB ecosystems and uses the audited noble-secp256k1 library. It is compatible with environments that do not support WASM, such as React Native.
