# 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

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