Usage

Initialize client and use class methods:

import { Client, Network } from '../src/client'

// Create a new client interface
const btcClient = new Client({ network: 'mainnet', nodeUrl: 'https://sochain.com/api/v2' })

// Set phrase
btcClient.setPhrase('phrase here')

// Get address
const address = btcClient.getAddress()

// Get balance
const balance = await btcClient.getBalance()

// Transfer with feeRate
const txid = await btcClient.transfer({ asset: AssetBTC, recipient: 'recipient address here', amount: baseAmount(100, BTC_DECIMAL), feeRate: 1 })

// Transfer with default feeRate (default is `fast`)
const txid = await btcClient.transfer({ asset: AssetBTC, recipient: 'recipient address here', amount: baseAmount(100, BTC_DECIMAL) })

// Get fee estimations
const { fast, fastest, average } = await btcClient.getFees()

// Get feeRate estimations
const { fast, fastest, average } = await btcClient.getFeeRates()

// Search transactions
const transactions = await btcClient.getTransactions({ address: 'address here', limit: 4 })

// Get a transaction with a given txId/hash
const txData = await btcClient.getTransactionData('b660ee07167cfa32681e2623f3a29dc64a089cabd9a3a07dd17f9028ac956eb8')
