npm i xrpio
```
# How it works
Transactions on the ripple blockchain are allowed to carry up to 1kB of arbitrary data via the memo field.
We can use this to store data of any size by building a tree of references between these transactions that can then be reassembled by reading them back from the blockchain.
In order to generate these transactions xrpio sends payments with the minimum denomination between two wallets controlled by the user.
xrpio automatically takes care of the logistics behind this technique as well as compression of the data.
Highly simplified, you can visualize the process like this:
![xrpio treewrite](https://i.imgur.com/G2HofSE.gif)
In practice each node does of course store significantly more data.
# 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**.
## <span style="color:red"> Operation on the main-net is untested and should not be used in production! </span>

# Quickstart
```typescript
import {RippleAPI} from 'ripple-lib'
import {treeRead, treeWrite} from 'xrpio'
import { xrpIO } from "xrpio"
const api = new RippleAPI({ server: "..." })
const api = new xrpIO("wss://some_ripple_node.net:51233")
await api.connect()
const dataRootHash = await treeWrite(
api,
"Arbitrary string data 123",
{
address: "Sender address",
secret: "Sender private key"
},
"Receiver address"
)
txHash = await api.treeWrite("arbitrary text 123", receiveWallet.address, sendWallet.secret)
data = await api.treeRead([txHash])
const data = await treeRead(api, [dataRootHash])
console.log(data) //"Arbitrary string data 123"
```
console.log(data) //"arbitrary text 123"
# A simple ready-to-run example for the testnet
```typescript
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)
})()
