Improving Web3 Safety. Automatically preserve the credibility of your audits with scans on every code change
Fidesium LTD is a smart contract security firm, incorporated in March 2023 and registered in the UK. We audit code for DeFi, RWA, gaming and infrastructure teams building on EVM and Solana.
A manual audit starts at $5,000. Continuous automated scanning starts at $399 a month. Penetration testing, security services and SOC 2 advisory are quoted against your scope.
23 of our audit reports are published in full at our public audit portfolio, covering 16 protocols. You can read the findings, the severities and the remediation before you speak to anyone here. That is why they are public.
| What you buy | Price | Where it is described |
|---|---|---|
| Manual smart contract audit | From $5,000 | Manual smart contract audits |
| Penetration testing | From $10,000 | Blockchain penetration testing |
| Continuous automated scanning | $399, $799 or $1,499+ a month | Pricing |
| Monitoring, bug bounties, architecture review | Quoted | Security services |
| SOC 2 advisory for Web3 | Quoted | SOC 2 field guide |
We publish our prices. You should not have to book a call to find out whether a range is anywhere near your budget. Knowing the floor before you start is worth more to you than a discount is.
A manual audit includes line-by-line human review, logic and economic risk analysis, and two rounds of fix verification. You get a public report, a badge and an on-chain NFT record, plus one month of continuous scanning after delivery. We are chain agnostic with an EVM specialism.
The first question anyone asks about a $5,000 audit is what was left out of it. It is a fair question and the answer is not a sentence on this page.
Every report we are permitted to publish is published in full, with the findings table, the severity breakdown and the commit hashes we reviewed. Among them.
The full list of 23 reports across 16 protocols is at the audit portfolio. Two of them are written up as case studies: Fidesium x Adrena and Fidesium x Sumvin, auditing a soulbound identity protocol on Sei.
Each audit is also minted as an on-chain NFT. The record of what was reviewed, at which commit, on which date, is verifiable and permanent, and it does not depend on us being around to confirm it.
| Protocol | Chain | Type | Report |
|---|---|---|---|
| Adrena | Solana | Perpetuals DEX | April 2026 |
| Sumvin | EVM | DeFi | February 2026 |
| Banana Zone | Solana | Gaming | December 2025 |
| Fore Protocol | EVM | DeFi | June 2025 |
| BlockAsset | Solana | RWA | January 2025 |
A building passes inspection on the day it is inspected. Then the owner adds a floor.
That is the problem Fidesium was built to address. An audit validates a set of assumptions about a specific commit at a specific moment. Then the team ships. Dependencies move, parameters change, a new module lands, and the conclusion in the report quietly stops describing the code that is actually running. Nobody did anything wrong. The audit simply decayed.
So our tooling re-runs audit-grade analysis on every commit, pull request and deployment. It integrates with GitHub and GitLab, checks meaningful logic changes at pull request level, and

15 years leading dev teams and using large data sets to compute actuarial risk in real time. Writing and auditing many smart contracts along the way.
