• Connection Management: Connect, disconnect, and manage wallet sessions
• Transaction Signing: Sign messages, transactions, and submit transactions to the network
• Network Management: Handle network changes and multi-network support
• Event System: Subscribe to wallet, account, and network change events
• State Management: Centralized state for connected wallet, account, and network information

Usage

Basic Setup

import { WalletCore } from "@aptos-labs/wallet-adapter-core";
import { Network } from "@aptos-labs/ts-sdk";

// Create wallet core instance
const walletCore = new WalletCore(
  [], // Optional: array of wallet names to opt-in (empty = all wallets)
  { network: Network.MAINNET }, // Optional: dapp configuration
  false, // Optional: disable telemetry (default: false)
  ["Petra Web"] // Optional: wallets to hide from display
);

// Get available wallets
const wallets = walletCore.wallets;
const notDetectedWallets = walletCore.notDetectedWallets;

Connecting to a Wallet

// Connect to a wallet by name
await walletCore.connect("Petra");

// Check connection status
if (walletCore.isConnected()) {
  console.log("Connected account:", walletCore.account);
  console.log("Connected network:", walletCore.network);
}

Signing Messages

const signedMessage = await walletCore.signMessage({
  message: "Hello, Aptos!",
  nonce: "random-nonce-123",
});

console.log("Signature:", signedMessage.signature);
console.log("Full message:", signedMessage.fullMessage);

Signing and Submitting Transactions

const result = await walletCore.signAndSubmitTransaction({
  data: {
    function: "0x1::aptos_account::transfer",
    typeArguments: [],
    functionArguments: [recipientAddress, amount],
  },
});

console.log("Transaction hash:", result.hash);

Listening to Events

// Account change event
walletCore.on("accountChange", (account) => {
  console.log("Account changed:", account);
});

// Network change event
walletCore.on("networkChange", (network) => {
  console.log("Network changed:", network);
});

// Disconnect event
walletCore.on("disconnect", () => {
  console.log("Wallet disconnected");
});

Disconnecting

await walletCore.disconnect();
