Submit Evidence

Hash locally, anchor on-chain.

Evidence files are hashed client-side and only their fingerprints are registered on-chain. Raw content stays under your control.

Evidence Submission

Evidence submission launching with testnet.

The evidence submission interface lets you classify a claim type, hash your evidence file or text locally using SHA-256, and anchor the resulting fingerprint on your chosen settlement chain. Raw files never leave your device. Available when protocol contracts are live on public testnet.
