How it works.

@ lets you send SOL or any SPL token to an email address. Funds lock in a non-custodial Solana escrow. The recipient gets an email, signs in with Google, and a wallet is created for them automatically.

Using the bot

/start — create your wallet (a one-time email code proves it's yours)
/send 1 SOL to alice@gmail.com — send to any email
/balance — view balances
/sent · /inbox — track envelopes
/reclaim <id> — recover expired funds

The vault

Emails are SHA-256-hashed before they ever reach the chain — plaintext stays off-chain. A claim is authorized by an off-chain verifier signature, checked in-program through Solana's native ed25519 program. Replay is blocked by a per-envelope nonce; each envelope can be claimed once, then the account closes. After expiry, anyone can return the funds to the sender — they can never get stuck.

Fees

0.5% per envelope goes to the treasury, which buys $@ daily and burns 100% of it.
