SECURITY BOUNDARY

Attestation is necessary.
It is not magic.

01

Attestcoin proves

Transaction inclusion and continuity to a finalized, attested Sepolia history.

02

ChargeProof verifies

Receipt status, source chain, canonical target, sender, selector, calldata, signer, amount, expiry, and replay keys.

03

The device represents

Physical delivery authenticity for this MVP. Secure elements and OCPP integration are production roadmap work.
