Aptos-AIP-62

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. AIP-62 also upgrades the data interfaces for interaction between DApps and wallets, such as the encapsulated RawTransaction, etc.

💡

Tip

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 Bitget 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: 'Bitget Wallet', icon: '...'}]

Connect Wallet

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

Parameters

name - string：wallet name

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

Get Wallet Address

        
         
        
import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
const { account } = useWallet(); // {address: '...', publicKey: '...'}

Get Network

        
         
        
import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
const { network } = useWallet();

Sign Message

Parameters

options
- message - string
- nonce - string

        
         
        
import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
const { signMessage } = useWallet();
 
const res = await signMessage({
  message: "The message to be signed and displayed to the user",
  nonce: "1",
});

Send Transaction

        
         
        
import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
const { signTransaction } = useWallet();
 
const transaction = {
  arguments: ["100000", "330679"],
  function:
    "0xc7efb4076dbe143cbcd98cfaaa929ecfc8f299203dfff63b95ccb6bfe19850fa::router::swap_exact_input",
  type: "entry_function_payload",
  type_arguments: [
    "0x1::aptos_coin::AptosCoin",
    "0x159df6b7689437016108a019fd5bef736bac692b6d4a1f10c941f6fbb9a74ca6::oft::CakeOFT",
  ],
};
try {
  const res = await signTransaction(transaction);
} catch (error) {
  // see "Errors"
}

Sign and Submit

        
         
        
import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
const { signAndSubmitTransaction } = useWallet();
 
try {
  const pendingTransaction = await signAndSubmitTransaction({
    data: transaction,
  });
} catch (error) {
  // see "Errors"
}

Verification

Signing information is intended to verify ownership of private resources.

        
         
        
import nacl from 'tweetnacl';
import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
const { signMessage, account } = useWallet();
 
const message = "hello";
const nonce = "random_string"
 
try {
  const response = await signMessage({
    message,
    nonce,
  });
  // Remove the 0x prefix
  const key = account.publicKey!.slice(2, 66);
  const verified = nacl.sign.detached.verify(Buffer.from(response.fullMessage),
                                             Buffer.from(response.signature, 'hex'),
                                             Buffer.from(key, 'hex'));
  console.log(verified);
} catch (error) {
  console.error(error);
}
