Aztec TypeScript Integration

Generate TypeScript code for interacting with Aztec contracts.

Subskills

• Contract Client - Type-safe contract interaction wrapper
• Wallet Setup - Wallet and node connection patterns
• Transaction Patterns - Common transaction patterns
• AuthWit Frontend - Client-side authorization witness implementation

Quick Start: Contract Interaction

Copyimport { MyContract } from "../artifacts/MyContract.js";
import { SponsoredFeePaymentMethod } from "@aztec/aztec.js/fee/testing";
import { TxStatus } from "@aztec/stdlib/tx";

// Get contract instance
const contract = MyContract.at(contractAddress, wallet);

// Call a method
const tx = await contract.methods.myMethod(arg1, arg2).send({
    from: account.address,
    fee: { paymentMethod }
}).wait({ timeout: 60000 });

if (tx.status === TxStatus.SUCCESS) {
    console.log('Transaction successful');
}

Generated Artifacts

After running aztec codegen, you get TypeScript bindings:

Copy// src/artifacts/MyContract.ts
import { MyContractContract } from "../artifacts/MyContract.js";

// Available methods
MyContractContract.deploy(wallet, ...args)  // Deploy new contract
MyContractContract.at(address, wallet)       // Connect to existing
contract.methods.myFunction(args)            // Call contract method

Key Imports

Copy// Contract and wallet
import { Wallet } from "@aztec/aztec.js/wallet";
import { AztecAddress } from "@aztec/stdlib/aztec-address";

// Transaction handling
import { TxStatus } from "@aztec/stdlib/tx";
import { TxReceipt } from "@aztec/stdlib/tx";

// Fee payment
import { SponsoredFeePaymentMethod } from "@aztec/aztec.js/fee/testing";

// Fields and types
import { Fr, GrumpkinScalar } from "@aztec/aztec.js/fields";

// Logging
import { Logger, createLogger } from "@aztec/aztec.js/log";

Transaction Flow

1. Get contract instance (at() or deploy())
2. Call method via contract.methods.xxx()
3. Send with fee payment .send({ from, fee })
4. Wait for confirmation .wait({ timeout })
5. Check status tx.status === TxStatus.SUCCESS
