Fly a note on Solana.
Public letter. The chain is the envelope. Your note rides along as a memo on a dust payment to your friend, and it stays there forever.
You send your friend 0.000001 SOL, and your note travels inside that same transaction. They read it by pasting the signature — no wallet connection, ever.
Who is it for?
What does it say?
what they will see
your note, in his handwriting
This is public. Anyone with the signature can read it.
Sign it in your own wallet
Moon Harvey builds the transaction unsigned and hands it to your wallet. It has never held a key.
Send it with my walletFill in the address and the note first.
No wallet extension? Send it by hand.
In whatever wallet you already use, send 0.000001 SOL to the address below and paste the memo into the memo field. Most wallets call it “memo” or “note”.
The memo must start with HARVEY| exactly, or Harvey will not recognise it.
Send them the link
Your wallet gives you a signature after it sends. Paste it here and you get a link that plays Harvey opening the letter.
Not an NFT and nothing is minted. It is a memo on a transfer, which is why it costs a fraction of a cent, why it cannot be taken down, and why anyone with the signature can read it.
