Bitcoin SDK is used to interact with the Bitcoin Mainnet or Testnet, it contains various functions can be used to web3 wallet. The SDK not only support Bitcoin, it also supports following chains:

• BTC
• BSV
• DOGE
• LTC
• TBTC

Getting Started

Installing BitCoin SDK

npm install @okxweb3/coin-bitcoin

What Can BitCoin SDK Do

- getMnemonic
- getRandomPrivateKey
- getDerivedPrivateKey 
- getNewAddress
- getAddressByPublicKey
- validAddress
- calcTxHash
- signTransaction
- validSignedTransaction 
- signMessage
- verifyMessage

Using BitCoin SDK

Get Private Key

get random private key

import { BtcWallet } from "@okxweb3/coin-bitcoin";

let wallet = new BtcWallet()
let privateKey = await wallet.getRandomPrivateKey();

get derived private key

import { BtcWallet } from "@okxweb3/coin-bitcoin";

let wallet = new BtcWallet()
let mnemonic = await getMnemonic(128);
let param = {
  mnemonic: mnemonic,
  hdPath: "m/44'/0'/0'/0/0"
};
let privateKey = await wallet.getDerivedPrivateKey(param);

Get New Address

get new address from private key

import { BtcWallet } from "@okxweb3/coin-bitcoin";

let wallet = new BtcWallet()

// legacy address
let params: NewAddressParams = {
  privateKey: "L22jGDH5pKE4WHb2m9r2MdiWTtGarDhTYRqMrntsjD5uCq5z9ahY"
};
let address = await wallet.getNewAddress(params);

// native segwit address
let params2: NewAddressParams = {
  privateKey: "L22jGDH5pKE4WHb2m9r2MdiWTtGarDhTYRqMrntsjD5uCq5z9ahY",
  addressType: "segwit_native",
};
let address2 = await wallet.getNewAddress(params2);

// nested segwit address
let params3: NewAddressParams = {
  privateKey: "L22jGDH5pKE4WHb2m9r2MdiWTtGarDhTYRqMrntsjD5uCq5z9ahY",
  addressType: "segwit_nested",
};
let address3 = await wallet.getNewAddress(params3);

// taproot segwit address
let params4: NewAddressParams = {
  privateKey: "L22jGDH5pKE4WHb2m9r2MdiWTtGarDhTYRqMrntsjD5uCq5z9ahY",
  addressType: "segwit_taproot",
};
let address4 = await wallet.getNewAddress(params4);

get new address from public key

import { BtcWallet } from "@okxweb3/coin-bitcoin";

let wallet = new BtcWallet()
let params5 = {
    publicKey: "03052b16e71e4413f24f8504c3b188b7edebf97b424582877e4993ef9b23d0f045",
    addressType: "segwit_taproot",
}
let address5 = await wallet.getAddressByPublicKey(params5);
