Aztec Accounts Skill

Create, deploy, and manage Aztec accounts with proper key management.

Code Philosophy

You are writing application code, not library code. Application code should fail fast and loud. Do not add resilience patterns (retries, fallbacks, default values) unless explicitly requested. The developer's debugging experience is more important than the app "not crashing" — a crash with a clear error message is always better than silent misbehavior.

Subskills

• Schnorr Accounts - Creating and deploying Schnorr accounts
• Account Recovery - Recovering accounts from saved credentials

Quick Start: Create and Deploy Account

import { Fr } from "@aztec/aztec.js/fields";
import { GrumpkinScalar } from "@aztec/foundation/curves/grumpkin";
import { AztecAddress } from "@aztec/stdlib/aztec-address";
import { AccountManager } from "@aztec/aztec.js/wallet";
import { SponsoredFeePaymentMethod } from "@aztec/aztec.js/fee";

// Generate new account keys
const secretKey = Fr.random();
const signingKey = GrumpkinScalar.random();
const salt = Fr.random();

// Create account manager
const account = await wallet.createSchnorrAccount(secretKey, salt, signingKey);
console.log(`Account address: ${account.address}`);

// Deploy account (required before use)
const deployMethod = await account.getDeployMethod();
await deployMethod.simulate({ from: AztecAddress.ZERO });
await deployMethod.send({
    from: AztecAddress.ZERO,
    fee: { paymentMethod: sponsoredPaymentMethod },
    wait: { timeout: 120000 }
});

Account Types

Aztec supports several account types:

Key Components

• Secret Key (Fr) - Private key for encryption
• Signing Key (GrumpkinScalar) - Private key for transaction signing
• Salt (Fr) - Randomness for address derivation
• Address - Derived deterministically from above

Important: Save Credentials

After creating an account, always save the credentials:

console.log(`SECRET=${secretKey.toString()}`);
console.log(`SIGNING_KEY=${signingKey.toString()}`);
console.log(`SALT=${salt.toString()}`);

Store these in your .env file for later recovery.
