Verify a Proof — TruthAnchor
Three levels of trust for verifying a TruthAnchor proof: Hosted View (fastest, trusts our server), Verify Independently (recommended, OCP-compatible, your browser queries chain RPC directly), and Raw Chain Record (highest, trust only the EVM via Etherscan/Polygonscan/BSCscan/Basescan).
Trust ladder — pick your level of scrutiny
These are three different trust models. We present them explicitly so you can choose the one that matches your audit needs. (1) Hosted View — reads TruthAnchor's cached record, fastest but trusts our backend. (2) Verify Independently — your browser queries the chain RPC directly; TruthAnchor's server is not in the trust path. This is the OCP-compatible mode. (3) Raw Chain Record — opens the transaction in the official block explorer; you decode the event log yourself and trust nothing but the chain state.
How Verification Works
Paste a transaction hash. In Independent mode, TruthAnchor reads the on-chain event directly via your browser, parses the anchored content hash, and confirms it matches what was registered. No account, no API key. The blockchain is the source of truth.
Supported Chains
Product anchoring runs on Polygon, Base, and BNB Smart Chain mainnets plus Sepolia testnet. The verified ERC-8263 reference contract is on Ethereum Mainnet — used for standard credibility and verification, not as the default user anchor path.
