How FlatBearer Works

1. Commit

Alice enters recipient address and amount, then commits FLAT behind a cryptographic hash.

2. Deliver

Click "Deliver Now" — our relayer calls reveal() on-chain. Bob receives FLAT instantly, paying zero gas.

Alt: Share Link

Or share a claim link for Bob to reveal later from any wallet (preserves privacy).

Privacy: The on-chain commit reveals nothing about the recipient or amount until reveal. Use Flashbots Protect RPC when revealing to prevent mempool snooping.

Safety: If the recipient never reveals, the sender can reclaim after 30 days. If the contract is permanently shut down, reclaim is immediate.

Guardian: A Gnosis Safe multisig can pause the contract in emergencies but cannot access funds. Guardian powers expire in April 2029.
