Deployment manifest chain identity does not match the chain

Error message

Deployment manifest chain identity does not match the chain anchor

What it means

The validator requires the deployment manifest's chain identity (chain_id and chain_name) to match the corresponding chain anchor's. A mismatch means the manifest describes a different chain than the anchor it is being verified against, which could route verification against the wrong network. Validation fails with this message.

Solutions

1. Regenerate the deployment manifest for the target chain so chain_id and chain_name match the anchor.
2. Correct the anchor's chain_id/chain_name if the manifest is the source of truth.
3. Add a pre-deploy script that asserts manifest chain identity equals the anchor before submitting configs.

Example fix

// before
let anchor = ChainAnchor { chain_id: 8453, chain_name: "base".into(), ..anchor }; // manifest is for sepolia (11155111)
// after
let manifest = build_manifest_for(8453, "base"); // regenerate manifest for the anchored chain

assert_eq!(
    config.deployment_manifest.chain_id, anchor.chain_id,
    "manifest chain_id must match anchor"
);
assert_eq!(
    config.deployment_manifest.chain_name, anchor.chain_name,
    "manifest chain_name must match anchor"
);

When it happens

Trigger: Validating a DeploymentConfig where `manifest.chain_id != anchor.chain_id` or `manifest.chain_name != anchor.chain_name` (e.g. manifest generated for mainnet, anchor configured for a testnet).

Common situations: Reusing a manifest across environments (mainnet vs Sepolia) with different anchors; renaming a chain in the anchor config without regenerating the manifest; copying a deployment bundle between chains with the same contracts.
