01
Switch on
Sign one message with Phantom. It becomes your inbox key, made right in your browser. It's free, and it's not a transaction.
02
Write
Paste any wallet and type. Your message is sealed with a fresh 256-bit key that only the two of you can unwrap.
03
Delivered on Solana
One transaction puts the sealed message on-chain. It lands in their inbox anywhere they open psst, and only their wallet can read it.
