Quick Answer

Opinion publishes five third-party audit reports covering conditional-token contracts, the exchange engine and fee manager, and OPN token contracts. The auditors named in the official report index are ScaleBit, Zellic and Pashov. These reports are useful evidence that specific code and scopes were reviewed at a point in time. They are not a guarantee that Opinion.trade, every later deployment, a user’s wallet or every transaction is completely safe.

​
Key Takeaways

  • The official Docs currently link to five audit reports from three audit providers.
  • Conditional Tokens were reviewed by ScaleBit and Zellic.
  • The Exchange Engine and Fee Manager were reviewed by ScaleBit.
  • OPN token contracts were reviewed by ScaleBit and Pashov.
  • Audit scope, reviewed commit or version, findings and remediation status must be read in the individual PDF.
  • Audits do not remove wallet, phishing, front-end, oracle, liquidity or market risk.

Published Opinion Audit Reports

This table mirrors the official OPINION audit index, verified on August 13, 2026. If the index and this Blog page ever differ, the current Docs and the report itself take precedence.

​
What an Audit Can Establish

A smart-contract audit can provide evidence about a defined codebase and review scope. Depending on the report, it may document:
  • which contracts, files or commits were reviewed;
  • the audit period and methodology;
  • findings grouped by severity;
  • the team’s response or remediation status;
  • limitations and areas outside the review.
The useful question is therefore not only “Was Opinion audited?” but also “Which component, which version, by whom, and what did the final report say?”

​
What an Audit Does Not Prove

An audit cannot establish that a product is risk-free. It may not cover:
  • code deployed after the reviewed version;
  • a user’s wallet, device or private-key security;
  • phishing or a lookalike domain;
  • third-party wallet, network or infrastructure failures;
  • market wording, resolution disputes or oracle evidence;
  • spread, liquidity or loss from a trading decision;
  • every possible interaction between audited and unaudited components.
Opinion’s Terms also identify risks including smart-contract and front-end vulnerabilities, hacks, phishing, social engineering, cryptoasset volatility and irreversible transactions.

​
How to Review an Audit Before Using the Product

  1. Start from the official audit index, not a PDF shared by an unknown account.
  2. Confirm the component you care about appears in the report scope.
  3. Read the report date, version or commit information.
  4. Review unresolved and acknowledged findings, not only the executive summary.
  5. Check whether the current product may have changed since the review.
  6. Apply separate wallet and domain-safety checks before signing a transaction.
For verified domains and social accounts, use the Official Opinion.trade Links page. For wallet responsibilities, read Opinion Custody and Fund Safety.

Where This Fits in a Legitimacy Check

Published audits are one positive verification signal. Other signals include official documentation, consistent domains, transparent market rules and a documented dispute process. None should be treated as a promise of profit or complete safety. Our broader Is Opinion.trade Legit? guide combines these signals with the risks a user should still evaluate.

​
What to Watch

  • New reports added to the official audit index.
  • Whether a report covers the current deployed version.
  • Changes to audited contracts or supported networks.
  • Newly disclosed risks, incidents or remediation updates.
  • Links that do not originate from an official Opinion domain.
