DA_VERIFY_FAILED

DA proof verification failed

What happened

The Merkle proof returned by the DA layer didn't verify against the expected digest — either the digest is wrong or the proof is corrupted.

How to fix

Recompute the digest from the original payload (DA.digest(bytes)) and re-verify. If still failing, re-fetch the proof from a different DA node.

Example

import { DA } from "@foundryprotocol/0gkit-da";
const digest = DA.digest(payload);
const ok = await da.verify(digest, proof);
