Freelance proof of delivery
Prove you sent it.
Stampedr fingerprints every file or delivery you send and locks a timestamp for it permanently on the blockchain. When a client says “I never got that” or “that wasn't due yet,” you send them a link instead of arguing.

How it works
Upload or paste
Add the file, text, or link you're delivering. It's fingerprinted right in your browser — never uploaded anywhere.
Stamp it
That fingerprint plus a timestamp gets locked permanently on Monad. Nobody — including you — can alter it afterward.
Share the link
If a client ever disputes what was sent or when, you send one link instead of arguing.
“We never received your file, and you missed the deadline.”
That's the argument Stampedr ends. Your fingerprinted, timestamped record was locked on Monad the moment you sent it — independently verifiable by anyone, and impossible for either side to alter after the fact. No more he-said-she-said. Just a link that settles it.
