Find the flaw Before Hackers do

DSA · Dowsers Static Analyser

The first check on the path to provable security with formal method
You fix bugs in development. You can’t fix them on-chain. DSA gives you 500+ automated checks across security vulnerabilities, token standards, DeFi integrations, and code quality.
Totally free.

What is DSA

You won’t know your contract has a flaw until it’s exploited.

DSA gives you 500+ automated checks to find them first — before you deploy, before it costs you. Submit your repository. Get a structured security report covering every risk domain your contract operates in.

Smart contracts fail in more ways than most teams check. DSA runs 500+ automated checks across 11 risk domains — from access control and upgradeability to DeFi protocol integrations, governance logic and more. Every category your contract touches, systematically inspected.

Access Control
Tokens & Standards
Security
DeFi Protocols
Upgradeability
Governance & DAO
Cross-chain
Transactions & Signatures
Math & Arithmetic
External Integrations
Compliance

Risk Classification

Every finding in your DSA report is mapped to one of four risk categories — so you know not just where the issue is, but what it costs you if left unaddressed.

WITHDRAW

Funds can be extracted to an unauthorized external address — exposing holders to partial or total capital loss through theft or access control exploits.

LOSS

Funds can be permanently destroyed or corrupted within the contract — through hidden burns, supply manipulation, or irreversible bugs — with no possibility of recovery.

BLOCK

Funds can become locked or untransferable, making them permanently inaccessible to their rightful owners and eliminating any liquidity or exit options.

CHANGE

The contract’s behavior can be altered after deployment — through undocumented admin rights or upgrade paths — enabling manipulation or fraud without holder consent.

How It Works

3 steps from repository to report.

DSA is designed to fit your development loop — not slow it down. Run it early, run it often, and use each report to close the gap before deployment.

01

Submit your repository

Paste your GitHub repository URL. DSA fetches, compiles, and runs 500+ automated checks on your smart contract code.

github.com/yourorg/your-contract
02

Accept terms and complete profile

Agree to terms of use — code is deleted after analysis, results are confidential. A form captures your name, role, and organisation.

03

Receive and iterate

Your structured report is delivered within 24 hours. Review, fix, resubmit. Use DSA at every iteration until the output is clean.

Fix → Resubmit → Repeat until clean

Who Uses DSA

Built for everyone who touches smart contract code.

DSA is the first tool any developer should run. It is also the first check any technical reviewer should perform.

Primary

Smart Contract Developers

Run DSA at the start of each development loop. Check 1 surfaces findings A, B, C. Fix. Check 2. Fix. Check 3 returns clean. Ship with evidence.

Technical

Protocol Teams & Web3 Agencies

A consistent, repeatable baseline across every contract in your stack — whether you are building for your own protocol or delivering for a client.

Technical Review

Anyone Who Reads Code Before Committing

Integrating a third-party contract. Evaluating a token before listing. Backing a project before investing. DSA gives you a fast, structured baseline on any smart contract — before you have skin in the game.
