The Lock
A sealed box built against the recipient wallet’s ed25519 key, derived to x25519. Encryption happens in your browser. The key never leaves it.

Your Money
Cash is being phased out. Your ledger should not become your biography. EYM adds one toggle to a real Solana transfer: open or sealed.

Honest row: in sealed mode an explorer still sees lamports moving. What it does not get is the note, the identity pairing inside the product, or the social graph. Level B removes the amount too.
Three parts
Fig. 03 / Anatomy
The Chain
Value moves as a normal Solana transfer through a single-use envelope account. Real signature, real slot, real explorer link.
The Cash
The recipient signs once to open. Unclaimed value returns to the sender after the window closes. Nothing is ever held by us.
AShipping
Social Seal
One-time envelope account. Note encrypted client-side. Amount, sender and note hidden inside the product.
BNext
Confidential Seal
Token-2022 confidential transfers where the stack allows it. The amount stops being trivially readable.
CLater
Hard Seal
A stronger shielded path. Not promised as live, not required to explain the product.
