Minimal example

  1. You will need to set up the dev enviornment required to run this example. For instructions, check out our docs here.

  2. If you're sending an extrinsic (i.e conducting a transaction) you will need to replace the demo seed phrase with your own seed phrase. The rest of the code should work as is.

  1. Inside your-file-name.ts, add the following code:
avail-js
import { SDK, WaitFor, Keyring, BN } from "avail-js-sdk"
 
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 replace with your own';
  const account = new Keyring({ type: "sr25519" }).addFromUri(Alice);
  const amount = new BN(10).pow(new BN(18)).mul(new BN(10000)) // 10_000 Avail
  const poolId = 1
 
  const result = await sdk.tx.nominationPools.join(amount, poolId, WaitFor.BlockInclusion, account)
  if (result.isErr) {
    console.log(result.reason)
    process.exit(1)
  }
 
  console.log(JSON.stringify(result, null, 4))
  process.exit()
}
main()
  1. Run the code using:
ts-node your-file-name.ts
