Basic Example

Inside your-file-name.ts, add the following code:

avail-js

import { Keyring } from "@polkadot/api"
import { SDK } from "avail-js-sdk"
import { WaitFor } from "avail-js-sdk/sdk/transactions"
import { BN } from "@polkadot/util"
 
const main = async () => {
  const providerEndpoint = "wss://turing-rpc.avail.so/ws";
  const sdk = await SDK.New(providerEndpoint)
 
  const Alice = 'This is a random seed phrase please do not use it';
  const account = new Keyring({ type: "sr25519" }).addFromUri(Alice)
  const dest = "5HGjWAeFDfFCWPsjFQdVV2Msvz2XtMktvgocEZcCj68kUMaw" // Eve
  const amount = new BN(10).pow(new BN(18)) // one Avail
 
  const result = await sdk.tx.balances.transferKeepAlive(dest, amount, WaitFor.BlockInclusion, account)
  if (result.isErr) {
    console.log(result.reason)
    process.exit(1)
  }
 
  console.log("From=" + result.event.from + ", To=" + result.event.to + ", Amount=" + result.event.amount)
  console.log("TxHash=" + result.txHash + ", BlockHash=" + result.blockHash)
 
  process.exit()
}
main()
