@tatumio/utxo-wallet-provider v1.0.3

🌍 UTXO Wallet Provider

UTXO Wallet Provider integrates seamlessly with Tatum SDK to provide extended wallet capabilities for UTXO-based blockchains.

📖 Description

The UTXO Wallet Provider provides an array of tools for:

• Generating mnemonics for seed phrases.
• Creating extended public keys (xpubs) from mnemonics.
• Deriving private keys and addresses from mnemonics and xpubs.
• Signing and broadcasting transactions to the UTXO-based networks.

It is built upon popular packages like bitcoinjs-lib, bitcore-lib, bip39, and bip32, ensuring a robust and secure foundation.

🚀 Quick Start

1. Installation

   Firstly, ensure that the @tatumio/utxo-wallet-provider package is set as a dependency within your project. Next, import the UTXO Wallet Provider extension:

   import { UtxoWalletProvider } from '@tatumio/utxo-wallet-provider';

2. Initialization

   Create an instance of Tatum SDK passing UtxoWalletProvider as one of wallet providers.

   const tatumSdk = await TatumSDK.init<Bitcoin>({
        network: Network.BITCOIN,
        configureWalletProviders: [
            UtxoWalletProvider,
        ]
    })

⚙️ Configuration

You can configure the UtxoWalletProvider as below to have all the checks skipped. This is useful for development and testing purposes.

const tatumSdk = await TatumSDK.init<Bitcoin>({
     network: Network.BITCOIN,
     configureWalletProviders: [
        {type: UtxoWalletProvider, config: {skipAllChecks: true}},
     ]
 })

🛠️ How to Use

1. Generate Mnemonic

   const mnemonic = tatumSdk.walletProvider.use(UtxoWalletProvider).generateMnemonic()

2. Generate xpub with or without Mnemonic

   const xpubDetails = await tatumSdk.walletProvider.use(UtxoWalletProvider).generateXpub(mnemonic)

3. Generate Private Key from Mnemonic

   const privateKey = await tatumSdk.walletProvider.use(UtxoWalletProvider).generatePrivateKeyFromMnemonic(mnemonic, 0)

4. Generate Address from Mnemonic or xpub

   const addressFromMnemonic = await tatumSdk.walletProvider.use(UtxoWalletProvider).generateAddressFromMnemonic(mnemonic, 0)
   const addressFromXpub = await tatumSdk.walletProvider.use(UtxoWalletProvider).generateAddressFromXpub(xpubDetails.xpub, 0)

5. Sign and Broadcast a Transaction

   Define your payload according to the UtxoTxPayload type using address as the source of payments:

   const payloadUtxo = {
      fromAddress: [{ address: 'YOUR_WALLET_ADDRESS', privateKey: 'YOUR_PRIVATE_KEY'}],
      to: [{ address: 'TARGET_WALLET_ADDRESS', value: 0.0001 }], // BTC_AMOUNT
      fee: '0.00001', // BTC_AMOUNT
      changeAddress: 'CHANGE_WALLET_ADDRESS',
      }
   const txHash = await tatumSdk.walletProvider.use(UtxoWalletProvider).signAndBroadcast(payloadUtxo)

   or using UTXOs as the source of payments:

   const payloadUtxo = {
      fromUTXO: [
         {
            txHash: '9bfddffd79a7af830a4070173b1f93547ee4eae9cdb542b153e2daaea1885f3d',
            index: 1,
            privateKey: 'YOUR_PRIVATE_KEY',
         },
        ],
      to: [{ address: 'TARGET_WALLET_ADDRESS', value: 0.0001 }], // BTC_AMOUNT
      fee: '0.00001', // BTC_AMOUNT
      changeAddress: 'CHANGE_WALLET_ADDRESS',
      }
   const txHash = await tatumSdk.walletProvider.use(UtxoWalletProvider).signAndBroadcast(payloadUtxo)

Remember to always ensure the safety of mnemonics, private keys, and other sensitive data. Never expose them in client-side code or public repositories.
