Smart Contract Security Audit
In Web3, code is money — and bugs are irreversible. Our auditors combine manual review with tooling to find the vulnerabilities that lead to drained funds and broken logic, before your contract goes live on-chain.

What this means. An authorized Solvex administrator registered and approved this exact public identity. What it does not. Solvex has not inspected the account on the platform, and this is not the platform's own verification.
Solvex specialists never ask for your passwords, recovery phrases, one-time codes, or payments to a personal account. Work, scope and invoices are agreed in writing through the official channels on this site.
Signed authorization required. This engagement is performed only against systems you own or are contractually authorized to have tested, under an agreed scope. See the responsible testing policy.
What's covered
- Manual line-by-line review of contract source
- Common vulnerability classes: reentrancy, overflow, access control
- Business-logic and economic-attack analysis
- Gas optimisation and best-practice review
- Automated analysis and fuzzing to support manual work
- Verification of fixes after remediation
What you receive
- Detailed audit report with severity-ranked findings
- Proof-of-concept for critical issues
- Remediation guidance with secure-code examples
- Re-audit of fixes
- Public audit summary for your community (optional)
Evidence and reporting
How the work is kept honest- Evidence, frozen at issuanceFindings tie to something observed. When the report is issued, the evidence behind it is frozen in the same transaction and cannot be edited afterwards.
- A signed reportAn Ed25519 signature covers both the report content and the delivered file. Alter a byte of either and verification fails.
- Signed scope firstTesting starts only after written scope and signed authorization for systems you own or are entitled to have tested.
Anyone holding a Solvex report can verify it publicly without seeing its contents.
Our boundaries
What this engagement does not do, stated before it starts.
- Audit of the contract version provided at a point in time
- No guarantee against all future exploits or dependency risk
- Off-chain and infrastructure components scoped separately
- No investment or financial advice on the project
How this engagement runs
- 01
Intake
Tell us the system, the goal and the constraints. If the work is not a good fit, we say so before anyone is invoiced.
- 02
Scope and authorization
Written scope and signed authorization before anything is touched. Security testing runs only against systems you own or are contractually entitled to have tested.
- 03
Investigation or build
Specialists matched to the work. Findings are proven by hand — scanner output is a lead, never a finding.
- 04
Evidence
Every finding ties to something observed. When a report is issued, its evidence is frozen in the same transaction, so what backed the report cannot change afterwards.
- 05
Delivery
A signed report: an Ed25519 signature over both the content and the file, with a short verification reference you can read down a phone.
- 06
Verification and retest
Anyone holding the report can verify it publicly without seeing its contents. Fixes are retested as part of the engagement — “fixed” means we confirmed it.
Questions we are asked
- Why is a smart contract audit so important?
- Because deployed contracts are immutable and hold real value. A single missed vulnerability can mean irreversible loss of funds. An audit before launch is far cheaper than an exploit after.
- What do you need from us?
- The contract source (ideally with tests and documentation), the commit to audit, and context on the intended behaviour and economic model. Frozen code speeds the audit.
- Do you provide a public report?
- Yes, if you'd like one for your community — a published audit summary builds trust. We agree what's disclosed, especially around any findings, before publication.
