TD TrustDrop

Fair file exchange without blind trust.

TrustDrop coordinates payment, proof, data availability, and key release so a buyer only pays when the protocol can verify the seller has fulfilled the exchange path.

Atomic purchase path

Funds are locked on-chain while fulfillment, proof verification, and settlement progress through a single exchange thread.

Proof-backed delivery

Seller actions are connected to zk verification and data availability checks before settlement can complete.

Buyer protection

If the exchange is not completed before the protocol deadline, the buyer keeps a refund path instead of relying on seller goodwill.
