    Library to assist in processing cryptocurrency payments.

    Getting Started

    npm i @faast/coin-payments
    import { CoinPayments } from '@faast/coin-payments'
    const coinPayments = new CoinPayments({
      seed: '5cf2d4a8b0...ca676651f'

    To begin processing payments, select your asset

    const xrpPayments = coinPayments.forAsset('XRP')
    await xrpPayments.init()

    Generate a deposit address. This is useful if you are a hot wallet and don't store the private key. You will need to keep track of which path node you are on (increasing int):

    let { address, extraId } = xrpPayments.getPayport(1234)
    // Customer sends deposit to `address` with destination tag `extraId`

    Validate an address:

    if (xrpPayments.isValidAddress(depositAddress)) {
      // do something

    Get the balance of an address:

    let { confirmedBalance, unconfirmedBalance } = await xrpPayments.getBalance(1234)

    Generate a sweep transaction for an address, then broadcast it:

    let unsignedTx = await xrpPayments.createSweepTransaction(1234, to)
    let signedTx = await xrpPayments.signTransaction(unsignedTx)
    let { id: txHash } = await xrpPayments.broadcastTransaction(signedtx)

    Generate a simple send transaction

    let unsignedTx = await xrpPayments.createTransaction(1234, to, '1.234')
    // Then sign and broadcast the transaction

    Get a transaction and check if it is confirmed:

    let txInfo = await xrpPayments.getTransactionInfo(txHash)
    if (txInfo.isConfirmed) {
      // txInfo.confirmations > 0

    In some circumstances, you may want a read-only copy that can do everything but sign. First create it with your seed as usual, then get the public config to use for read only version.

    const readOnlyConfig = coinPayments.getPublicConfig()
    const readOnlyCoinPayments = new CoinPayments(readOnlyConfig)

    See tests or types for more utilities
