Minimal example
-
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.
avail-js
- Inside
your-file-name.ts
, add the following code:
avail-js
import * as dotenv from 'dotenv';
import { Account, SDK, Pallets } from 'avail-js-sdk';
dotenv.config();
export async function nominationPoolsNominate() {
// 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);
// Pool ID to nominate from
const poolId = 1;
console.log(`Pool ID: ${poolId}`);
// Validator targets to nominate
const validators = [
"5GNJqTPyNqANBkUVMN1LPPrxXnFouWXoe2wNSmmEoLctxiZY", // Alice Stash
"5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty", // Bob
];
// Create nominate transaction
const tx = sdk.tx.nominationPools.nominate(poolId, validators);
console.log("Submitting pool 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("\nPool nomination completed successfully");
// Log all transaction details
console.log("\nTransaction Details:");
console.log(`Transaction Hash: ${res.txHash}`);
console.log(`Block Hash: ${res.blockHash}`);
console.log(`Block Number: ${res.blockNumber}`);
process.exit(0);
}
// Execute the function
nominationPoolsNominate();
- Run the code using:
