CardanoWall builds proofs in four layers: a plain hash timestamp, an optional signature, an encrypted sealed copy, and private delivery to specific recipients. You use only the layers a situation needs.

CardanoWall publishes a small proof record on Cardano, not your file. A hash-only proof exposes only a digest, while a sealed proof keeps the content encrypted off-chain — here's exactly what becomes public.

Share a receive address. Your client scans the public Label 309 feed and locally decrypts the records your keys can open — no server-side mailbox, no recipient list on chain.

CardanoWall Desktop is an open-source, cross-platform client for Label 309 — local identities, an offline-first record mirror, a sealed inbox, sent-record tracking, and your choice of gateway. Here is how it works.

In CardanoWall, signing, sealing, and decryption all happen locally — the gateway publishes proofs and stores ciphertext but is designed never to receive your private keys.

Publishing a CardanoWall proof costs money because the gateway pays real Cardano transaction fees and, for files, real Arweave storage — then adds a service margin to run a hosted service. Verifying stays free and needs no server.
