Question

What is the best way to detect account switching in Phantom Wallet? I am using Nextjs.

Answer 1

From the docs: establishing-a-connection#changing-accounts

There are different methods to detect the provider.

provider.on('accountChanged', (publicKey) => {
    if (publicKey) {
        // Set new public key and continue as usual
        console.log(`Switched to account ${publicKey.toBase58()}`);
    } 
});
