Can I change the email that is associated with my wallet address?

Ramper does not support changing the emails associated with your wallets.

In case you log in to Ramper using social media accounts: the email associated with your wallet is typically linked to your social media account. To change it, you'll need to update the email on your social media account.

In any case, you may consider creating a new wallet with the new email and then transferring your assets from the current wallet to this new wallet.
