Easy to use Blockbook Provider and Signer object for Bitcoin-like Coins
-
Ethers.js like Provider & Signer object for Bitcoin-fork coins (Bitcoin, Litecoin, Dogecoin, etc.)
-
Provider library for Blockbook & Mempool (electrs) API
-
Can compose necessary signed & unsigned PSBT Transaction Object from BIP39 Mnemonic Seed / Private Key (WIF) / View only (Public Key)
-
Does not require deep understanding of how to compose bitcoin transactions from scratch (the reason why this library exists).
-
Taproot Support (HD Taproot Signer still WIP)
-
Blockbook (Recommended as it supports xpub addresses and have various coin support like Dogecoin and ZCash)
-
Mempool (Electrs) Instances (mempool.space, litecoinspace, blockstream.info)
-
[] Blockchair (Maybe at the future)
-
[] More API integration (Blockchair, etc)
-
[] Migrate PSBT generation from bitcoinjs to @scure/btc-signer to support bigint (to support Dogecoin, etc)
-
[] Deprecate number input, only accept bigint for sat amounts
-
[] Custom decimals (if possible)
-
[] Dogecoin / Bitcoin Cash / Bitcoin Gold / Zcash (transparent) support
-
[] Add test cases with mocking provider
-
[] Add example networks like ethers.js ( that could be loaded from string, tickers. btc, ltc, would be great )
// bitcoin reexports bitcoinjs lib
import { bitcoin, MnemonicWallet, MempoolProvider } from 'btc-signer';
const provider = new MempoolProvider({

const wallet = new MnemonicWallet(mnemonic, provider, {
