Evidence in. Verifiable receipt out.

PactVerity's operational browser engine applies published deterministic rules to measurable service evidence, creates a portable SHA-256 receipt and re-verifies imported receipts locally.

Public MVP:The engine evaluates user-supplied evidence. It does not independently monitor a service, escrow funds, execute settlement, publish receipts on-chain or prove that supplied evidence is true.

04 / What it proves

Consistency and key control—within clear limits.

The verifier exposes what can be recomputed and what still requires trusted evidence collection or on-chain enforcement.

Proves

Deterministic result

The normalized inputs reproduce the listed checks, outcome and domain-separated SHA-256 digest under engine version 1.0.0.

Optional

Wallet key control

A valid Ed25519 signature proves that the corresponding Solana key signed that exact receipt digest. It does not prove a real-world identity, role or evidence source.

Does not prove×

Evidence truth

The MVP does not independently collect evidence, establish trusted time, confirm service delivery, move funds or execute a refund.
