Quick Start

Let's start with installing @perawallet/connect

npm install --save @perawallet/connect

// Connect handler
peraWallet
  .connect()
  .then((newAccounts) => {
    // Setup the disconnect event listener
    peraWallet.connector?.on("disconnect", handleDisconnectWalletClick);

    setAccountAddress(newAccounts[0]);
  })
  .reject((error) => {
    // You MUST handle the reject because once the user closes the modal, peraWallet.connect() promise will be rejected.
    // For the async/await syntax you MUST use try/catch
    if (error?.data?.type !== "CONNECT_MODAL_CLOSED") {
      // log the necessary errors
    }
  });

If you don't want the user's account information to be lost by the dApp when the user closes the browser with user’s wallet connected to the dApp, you need to handle the reconnect session status. You can do this in the following way.

// On the every page refresh
peraWallet.reconnectSession().then((accounts) => {
  // Setup the disconnect event listener
  peraWallet.connector?.on("disconnect", handleDisconnectWalletClick);

  if (accounts.length) {
    setAccountAddress(accounts[0]);
  }
});

After that you can sign transaction with this way

// Single Transaction
try {
  const signedTxn = await peraWallet.signTransaction([singleTxnGroups]);
} catch (error) {
  console.log("Couldn't sign Opt-in txns", error);
}

// Group Transaction
try {
  const signedTxns = await peraWallet.signTransaction([multipleTxnGroups]);
} catch (error) {
  console.log("Couldn't sign Opt-in txns", error);
}

Customizing Style

You can override the z-index using the .pera-wallet-connect-modal class so that the modal does not conflict with another component on your application.

.pera-wallet-connect-modal {
  // The default value of z-index is 10. You can lower and raise it as much as you want.
  z-index: 11;
}

Your app name on Pera Wallet

By default, the connect wallet drawer on Pera Wallet gets the app name from document.title.

In some cases, you may want to customize it. You can achieve this by adding a meta tag to your HTML between the head tag.

<meta name="name" content="My dApp" />
