이 패키지가 제공하는 것

• 라이트코인 Client 구현 (UTXO‑스타일 체인)
• 주소 생성 및 검증
• 잔액, 거래 내역, 거래‑데이터 조회
• 수수료‑예측 도우미 (getFeeRates, getFeesWithMemo 등)

XChainJS docs:

기능

• ✅ TypeScript‑first 라이트코인 SDK
• ✅ BIP44/84 주소 파생 지원 (메인넷 및 테스트넷)
• ✅ 니모닉 구문으로 주소 생성
• ✅ 주소 검증
• ✅ 잔액, 거래 내역 및 해시별 거래 데이터 조회
• ✅ LTC 전송
• ✅ 수수료 추정 도우미 (getFeeRates, getFeesWithMemo, …)

How it works (under the hood)

• bitcoinjs-lib을 사용하여 UTXO 트랜잭션을 빌드하고 서명합니다.
• 기본 공개 데이터 제공 엔드포인트로 SoChain API v2를 사용합니다.
• 탐색기 URL은 Blockstream을 참조합니다.
• 공유 XChainJS 패키지에 의존합니다: @xchainjs/xchain-client, @xchainjs/xchain-crypto, @xchainjs/xchain-util.

기본 사용 예시

새 Litecoin 클라이언트에 지갑 연결하기

import { Client } from '@xchainjs/xchain-litecoin'
import { Network } from '@xchainjs/xchain-client'
import { baseToAsset } from '@xchainjs/xchain-util'

const connectWallet = async () => {
  const phrase = 'your mnemonic phrase here'
  const ltcClient = new Client({ network: Network.Mainnet, phrase })

  const address = ltcClient.getAddress()
  console.log('Address:', address)

  const isValid = ltcClient.validateAddress(address)
  if (!isValid) throw new Error('Invalid address')

  const balances = await ltcClient.getBalance(address)
  const readable = baseToAsset(balances[0].amount).amount()
  console.log('Balance:', readable.toString())
}

connectWallet().catch(console.error)

Litecoin (LTC) 전송

import { Client, LTC_DECIMAL } from '@xchainjs/xchain-litecoin'
import { assetToBase, assetAmount } from '@xchainjs/xchain-util'

const transferLitecoin = async () => {
  const phrase = 'your mnemonic phrase here'
  const recipient = 'ltc recipient address here'

  const ltcClient = new Client({ phrase })

  const amount = assetToBase(assetAmount(0.01, LTC_DECIMAL))

  const txid = await ltcClient.transfer({
    amount,
    recipient,
    memo: 'memo',
  })

  console.log('TX sent:', txid)
  console.log('Explorer:', ltcClient.getExplorerTxUrl(txid))
}

transferLitecoin().catch(console.error)

전송 수수료 및 수수료‑비율 추정값 가져오기

import { Client } from '@xchainjs/xchain-litecoin'
import { baseToAsset } from '@xchainjs/xchain-util'

const returnFees = async () => {
  const phrase = 'your mnemonic phrase here'
  const ltcClient = new Client({ phrase })

  const { fast, fastest, average } = await ltcClient.getFees()
  console.log('Fast:', baseToAsset(fast).amount().toString())
  console.log('Fastest:', baseToAsset(fastest).amount().toString())
  console.log('Average:', baseToAsset(average).amount().toString())

  const feeRates = await ltcClient.getFeeRates()
  console.log('FeeRates:', feeRates)
}

returnFees().catch(console.error)

transfer 매개변수에 feeRate를 전달할 수 있습니다:

// feeRates.fastest is a number
await ltcClient.transfer({
  amount,
  recipient,
  memo: 'memo test',
  feeRate: feeRates.fastest,
})

거래 데이터 및 거래 내역 가져오기

import { Client } from '@xchainjs/xchain-litecoin'

const transactionData = async () => {
  const phrase = 'your mnemonic phrase here'
  const ltcClient = new Client({ phrase })

  const hash = 'your tx hash'
  const txData = await ltcClient.getTransactionData(hash)
  console.log('TxData:', txData)
}

transactionData().catch(console.error)
