$5K CONTENDER PRIZE: ENVELOPE

@envelope_solana brings private payments, gift links and shared event pots to mobile, with proofs generated on your phone.
Some correspondence belongs in a sealed envelope, transmitted through an intergalactic pocket phone.

Send money to someone who isn't on Envelope yet.

Make a gift link in private dollars or SKR, add a message, and share it. The amount stays hidden, claiming costs them nothing, and you can take it back if unclaimed.

@gr8_sol Thanks! Neither.

It's Solana's native Confidential Balances, with proofs from Solana's zk-sdk running as WASM on the phone. No circuits. A relayer and an SKR-fuelled gas tank cover the SOL.

SKR runs Envelope.

Hold and send SKR privately, with the amount encrypted on-chain. SKR pays every fee, no SOL.

Member (100 SKR): pay 2 once.
Business (500 SKR): pay 4 at once, unlimited pots.

Trending feature on Envelope: Statements 🔒

Prove a payment or your balance to an accountant auditor or to a friend, and nothing else. Every figure is checked against Solana with a zero-knowledge proof.

No key shared. Nothing to revoke.
