Transaction verification

Did this transaction anchor a batch?

Paste a transaction hash. We check its receipt, the Base Sepolia chain, the anchor contract event and the event’s canonical block.

Read-only check. This page never asks for a wallet or private key.

Local proof check · no upload

Does a receipt belong to this batch?

Choose the batch manifest and enter one receipt ID. Your browser recomputes the Merkle root, matches every public batch field, and checks the receipt’s inclusion proof against the verified anchor.

First verify the anchor transaction above. Receipt membership is meaningful only when bound to a confirmed on-chain batch root.

This proves the supplied receipt ID is a leaf in the manifest committed by this anchor. It does not disclose or validate the receipt contents, prove the source data is truthful, or establish that a model outcome was safe.

WHAT THIS PAGE CHECKS

A successful Base Sepolia transaction, its canonical block, the publisher-scoped batch event, and locally recomputed receipt membership against the anchored root when you provide a manifest.

WHAT THIS PAGE DOES NOT CLAIM

Membership proves inclusion of an identifier only. It does not validate the receipt contents, prove the source data is truthful, or prove an AI outcome was correct or safe.

Testnet data only. The anchor stores a commitment and batch metadata, not source prompts, model inputs, outputs or other private evidence. A later authenticated workspace will join private receipts and membership proofs to these public anchors.
