Sealed media proof
Send sensitive files with proof they were not changed.
Transfer sensitive files with verified sender identity, encrypted contents, and independent proof.
Anchored on Base
Encrypted before it leaves you
Files are sealed in your browser. Kirk Ledger stores ciphertext and proof — never your plaintext.
Anchored on Base
A hash of the sealed envelope is anchored on Base L2, so anyone can prove it was not changed after sealing.
Scoped recipient access
Only the recipients you authorize can decrypt the contents. Access is bound to verified identity.
Independently verifiable
Share a verify link. A third party confirms the proof without trusting Kirk Ledger with the contents.
