bitcoinjs-lib is a client-side Bitcoin library for Node and browsers: build/sign transactions via PSBT, create addresses and payment outputs (P2PKH, P2SH, P2WPKH, P2WSH, P2TR), decode/encode addresses. Keys come from ecpair and bip32; ECC must be initialized with initEccLib for signing and Taproot.
