Web3 security: match the audit to the deployed system

Ethereum’s developer guidance recommends independent security review while cautioning that an audit will not catch every bug. It places review alongside testing and other development practices, rather than treating a report as a complete safety guarantee. That distinction is useful to buyers who encounter an audit badge without the underlying scope or release information.

OpenZeppelin’s access-control documentation describes privileged roles and timelocks that can delay administrative actions. It also identifies availability risks when critical accounts become unavailable. These mechanisms are tools with operational consequences; their presence alone does not establish that a particular contract, role assignment or recovery arrangement is safe.

Our recommended evidence pack begins with a deployment map: network, contract addresses, implementation and proxy relationships where relevant, release identifiers and configuration. Add the report’s reviewed repository or commit, the components explicitly excluded and the disposition of each finding. The buyer should be able to identify the gap between what was reviewed and what is currently deployed without relying on a verbal assurance.

Next map authority. Identify who can upgrade, pause, mint, transfer assets, change permissions or recover administrative access. Distinguish the player’s powers from the studio’s and the infrastructure supplier’s. Request a demonstration of the actual approval and delay settings in a controlled environment. A planned multisignature arrangement is different evidence from the signers and permissions operating today.

The most revealing exercise is a change scenario. Ask what happens when a reviewed contract is upgraded, a dependency is replaced or a privileged signer leaves the business. Record who assesses the change, which evidence needs renewal and what prevents an unapproved release. Include the front end and wallet service in the assessment when their behaviour affects what a player signs; those components may sit outside the contract audit.

Finally rehearse failure and exit. Use test accounts and assets to exercise lost access, a supplier outage and a compromised integration. Capture the recovery path, communication owner and functions that remain unavailable. The acceptance record should state the tested version and unresolved risks. This produces a decision that can be reviewed after the next change, rather than a permanent security claim attached to a logo.
