# Aptos-AIP-62

The AIP-62 standard is a new standard officially introduced by Aptos. It is a set of chain-agnostic interfaces and conventions designed to improve the interaction between applications and injected wallets. It uses the Wallet Standard method to detect installed wallets and automatically display a list of connectable wallets. The AIP-62 also upgrades the data interfaces for interaction between DApps and wallets, such as the encapsulated RawTransaction, etc.

Note:

In the near future, as wallets adopt the new standard, wallet adapters will deprecate the old standard and only retain support for the AIP-62 wallet standard.

When running a DApp in the SafePal Wallet App or in the Chrome browser with the Chrome Extension installed, the app can achieve wallet injection by wrapping AptosWalletAdapterProvider.

import { AptosWalletAdapterProvider } from "@aptos-labs/wallet-adapter-react";
<AptosWalletAdapterProvider autoConnect>
  <App />
</AptosWalletAdapterProvider>;

# Get wallet list

DApps can directly use hooks to get the list of wallets registered via registerWallet:

import { useWallet } from "@aptos-labs/wallet-adapter-react";
const { wallets } = useWallet(); // [{name: 'SafePal Wallet', icon: '...'}]

# Connect to SafePal Wallet

Pass the wallet name to the connect method to connect to a specified wallet:

Note:

After the user has approved the connection for the first time, the web app's domain will be remembered for the future sessions.

See the example code below:

import { useWallet } from "@aptos-labs/wallet-adapter-react";
const { connect } = useWallet(); // [{name: 'SafePal Wallet', icon: '...'}]
await connect("SafePal Wallet");
