​
useCreateWallet()

Creates a new Argent-compatible wallet on StarkNet. This hook deploys the wallet contract behind the scenes and uses Avnu’s paymaster to sponsor gas fees, resulting in a frictionless onboarding experience.

​
Parameters

  • pin (string): A user-defined numeric code or password used to encrypt the wallet’s private key.

​
Return Value

Returns an object containing:
  • createWalletAsync: Function to trigger wallet creation
  • createWalletResponse: Object with deployment results
  • isLoading: Boolean indicating if the operation is in progress
  • error: Any error that occurred during the process

​
Example Implementation

'use client'

import { useCreateWallet } from "@chipi-pay/chipi-sdk";
import { useState } from "react";

export function CreateWallet() {
  const { 
    createWalletAsync, 
    createWalletResponse, 
    isLoading, 
    error 
  } = useCreateWallet();
  
  const [pin, setPin] = useState('');

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    try {
      await createWalletAsync(pin);
      alert('Wallet created successfully!');
    } catch (err) {
      console.error('Wallet creation failed:', err);
    }
  };

  return (

Code Breakdown

​
1. Form Handling

const [pin, setPin] = useState('');
  • Manages PIN input state
  • Validates minimum length of 4 characters

​
2. Wallet Creation

const handleSubmit = async (e: React.FormEvent) => {
  e.preventDefault();
  try {
    await createWalletAsync(pin);
    // ...
  } catch (err) { /* ... */ }
};
  • Uses createWalletAsync from the SDK hook
  • Handles success/error states

​
3. Security Implementation

<input
  type="password"
  // ...
/>
  • PIN input is masked
  • Never stored in plain text
  • Client-side encryption only

​
4. Result Display

{createWalletResponse && (
  <div className="mt-6">
    {/* ... */}
    <a href={`https://starkscan.co/...`}>
    {/* ... */}
  </div>
)}
  • Shows wallet address and transaction hash
  • Links to StarkScan for verification

​
Production Notes

  1. PIN Security
    • Always collect PINs client-side
    • Never log or store raw PIN values
    • Use secure encryption before any transmission
  2. Error Handling
    • Catch and handle RPC connection errors
    • Monitor paymaster API limits
    • Implement retry logic for failed deployments
  3. Wallet Storage
    • Store encrypted private key securely
    • Associate with user session (not persistent storage)
    • Consider implementing backup/recovery flows
  • Transfer - Send tokens from your new wallet
  • Stake - Participate in staking protocols
:::success Wallet creation is free! Gas fees are covered by our paymaster integration. :::
