SignEscrow

The SignEscrow contract acts as a trusted intermediary between the customer and the shipper, managing funds in a secure and transparent manner. By utilizing Sign Protocol, the contract automates the escrow process with verifiable attestations that confirm each step of the transaction.

Key Features

•	Secure Fund Management: The contract holds the customer’s payment in escrow until the shipment and receipt of goods are confirmed by both parties, ensuring the shipper is paid only when conditions are met.
•	Blockchain Attestations: Using the EthSign Protocol, the contract creates on-chain attestations to verify that both the shipment and receipt have been confirmed, adding an extra layer of trust and transparency.
•	Decentralized and Trustless: No intermediaries or third parties are required; the contract executes transactions based on coded rules, minimizing the risk of fraud.
•	Flexible Cancellation: The owner of the contract can cancel the escrow and refund the customer if shipment and receipt are not confirmed, allowing for resolution in case of disputes.
