I'm working on a project where I need to encrypt a message and send it over the blockchain so that only the intended recipient can decrypt it. The challenge is that I only have the recipient's Ethereum address, but encryption typically requires their public key.
Since Ethereum addresses are derived from the public key but don’t expose it directly, I’m looking for the best approach to encrypt data for a recipient without having their full public key beforehand.
How to tackel this any idea??
