Minimal example
Note
You will need to set up the dev environment required to run this example.
For instructions, check out our docs here.
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.
Inside your-file-name.ts, add the following code:
import * as dotenv from 'dotenv';import { Account, SDK, Pallets } from 'avail-js-sdk';dotenv.config();export async function stakingNominate() { // Initialize SDK with Turing endpoint const sdk = await SDK.New('wss://turing-rpc.avail.so/ws'); // Create account from seed in .env file const seed = process.env.SEED; if (!seed) { throw new Error("SEED environment variable is not set"); } // Create account from seed const account = Account.new(seed); console.log("Account Address: ", account.address); // Validator targets to nominate const targets = [ "5GNJqTPyNqANBkUVMN1LPPrxXnFouWXoe2wNSmmEoLctxiZY", // Alice Stash "5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty", // Bob ]; console.log("Nominating validators:"); targets.forEach((target, index) => { console.log(` ${index + 1}. ${target}`); }); // Create nominate transaction const tx = sdk.tx.staking.nominate(targets); console.log("Submitting nomination transaction..."); // Execute and wait for inclusion const res = await tx.executeWaitForInclusion(account, {}); // Check if transaction was successful const isOk = res.isSuccessful(); if (isOk === undefined) { throw new Error("Cannot check if transaction was successful"); } else if (!isOk) { throw new Error("Transaction failed"); } console.log("Nomination completed successfully"); console.log(`Transaction Hash: ${res.txHash}`); console.log(`Block Hash: ${res.blockHash}`); process.exit(0);}// Execute the functionstakingNominate();
