xrpio/README.md

Overview

xrpio is a library that allows you to write and read arbitrary data in the ripple blockchain.

How to install

npm i xrpio

Caution

This library is in an early stage of development and breaking changes may occur spontaneously and without regard of semantic versioning until the v1.0.0 release.

Operation on the main-net is untested and should not be used in production!

Quickstart

import {RippleAPI} from 'ripple-lib'
import {treeRead, treeWrite} from 'xrpio'

const api = new RippleAPI({ server: "..." }) 
await api.connect()

const dataRootHash = await treeWrite(
    api, 
    "Arbitrary string data 123", 
    { 
        address: "Sender address", 
        secret: "Sender private key"
    }, 
    "Receiver address"
)

const data = await treeRead(api, [dataRootHash])
console.log(data) //"Arbitrary string data 123"

A simple ready-to-run example for the testnet

import { treeRead, treeWrite, Wallet } from 'xrpio'
import { RippleAPI } from 'ripple-lib'
import fetch from 'node-fetch'

export const makeTestnetWallet = () : Promise<Wallet> => fetch('https://faucet.altnet.rippletest.net/accounts', {
    method: 'POST',
    headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json'
    },
}).then((raw:any) => {
    return raw.json().then(content => content.account)
});

(async()=>{
    const api = new RippleAPI({server: 'wss://s.altnet.rippletest.net:51233'})
    await api.connect()
    const fromWallet = await makeTestnetWallet()
    const toWallet = await makeTestnetWallet()
    await new Promise((res, rej) => setTimeout(res, 10000)) //it takes a moment for the wallets to become active

    const rootHash = await treeWrite(api, "test123", fromWallet, toWallet.address)
    const data = await treeRead(api, [rootHash])
    console.log(data)    
})()
