#Installation
Magic interacts with the Bitcoin blockchain via Magic's extension NPM package @magic-ext/bitcoin. The Bitcoin extension also lets you interact with the blockchain using methods from Bitcoinjs-lib.

NPM
Yarn
01npm install --save @magic-ext/bitcoin
#Initialization
Typescript
01import { Magic } from 'magic-sdk';
02import { BitcoinExtension } from "@magic-ext/bitcoin";
03
04const magic = new Magic('YOUR_API_KEY', {
05 extensions: [
06 new BitcoinExtension({
07 rpcUrl: 'BTC_RPC_NODE_URL',
08 network: 'testnet' // testnet or mainnet
09 }),
10 ],
11});
#Common Methods
#Sign Transaction
To send a standard Bitcoin blockchain transaction, you can call the magic.bitcoin.signTransaction method to get the signature and raw transaction then send to blockchain by yourself.
Javascript
01import { Magic } from 'magic-sdk';
02import { BitcoinExtension } from "@magic-ext/bitcoin";
03import * as bitcoin from 'bitcoinjs-lib'

05const magic = new Magic('YOUR_API_KEY', {
06 extensions: [
07 new BitcoinExtension({
08 rpcUrl: 'BTC_RPC_NODE_URL',
09 network: 'testnet' // testnet or mainnet
10 }),
11 ],
12});
13
14const TESTNET = bitcoin.networks.testnet;
15
16const tx = new bitcoin.TransactionBuilder(TESTNET);
17tx.addInput('fde789dad13b52e33229baed29b11d3e6f6dd306eb159865957dce13219bf85c', 0);

21const txHex = tx.buildIncomplete().toHex();

23const signedTransactionHex = await magic.bitcoin.signTransaction(txHex, 0);
