How this service works
USD/CAD forex exchange rate — US dollar to Canadian dollar loonie rate — Ed25519 signed attestation
Output
Returns the current USD/CAD exchange rate along with an Ed25519 digital signature attesting to the price, enabling downstream verification of data authenticity and provenance.
Example use cases
Cross-border payment verification for merchant
“Before I process this payment from a US customer to a Canadian vendor, I need the latest signed USD to CAD rate so I can lock in the exact conversion and prove it was legitimate at settlement time.”
Smart contract price feed initialization
“I'm deploying a DeFi protocol that needs to know the current USD/CAD rate. Can you fetch me a cryptographically signed attestation so I can verify the price came from a trusted source before writing it on-chain?”
Accounting reconciliation with audit trail
“Pull the current USD to Canadian dollar exchange rate with a digital signature attached. I need to record this in our books with proof that shows exactly what rate we used and that it hasn't been tampered with.”
