50+ Cryptocurrency & Web3 targets assessed

Crypto platform security
where vulnerabilities mean lost funds

Cryptocurrency exchanges and DeFi platforms are high-value targets. Attackers specifically hunt for auth bypasses, wallet manipulation, and smart contract interactions that lead to direct fund theft.

How a Cryptocurrency & Web3 engagement runs

Crypto platforms get tested the way attackers actually work them: account-takeover chains through reset and session flows, withdrawal-path abuse, rate-limit bypasses on trading endpoints, and API keys that leaked into a client bundle. Because transactions are irreversible, we verify exploitability end-to-end rather than stopping at 'suspicious response'.

Assessment windows are coordinated around market hours and release cycles — trading systems cannot pause for a test. Findings arrive with impact stated in the terms that matter here: funds at risk, accounts exposed, and the exact request sequence that proves it.

Regulatory and compliance context

Crypto platforms sit between regimes: custody and transfer rules vary by jurisdiction, Travel Rule obligations apply to VASPs, MiCA now governs EU-facing services, and most institutional partners still expect SOC 2-style evidence before integrating. Regulators increasingly treat a wallet or exchange bug as a consumer-protection event, not an IT incident — which means a finding that leaks balances or enables an unauthorized withdrawal carries regulatory exposure on top of the direct loss. Our reports are written so a compliance lead can lift the relevant section straight into an incident or vendor review.

What we typically find in Cryptocurrency & Web3

The repeat offenders in crypto testing are withdrawal-flow logic flaws — a signed request that can be replayed with a different amount, a two-step confirm that skips the second check — and IDORs on portfolio, transaction-history, and KYC-document endpoints. We regularly find API keys with withdrawal scope exposed in client bundles or CI artifacts, webhook handlers for custodial deposits that trust unsigned callbacks, and session tokens that survive a password reset. Wallets that bridge to smart contracts frequently trust the contract's view of state without server-side verification, which turns a benign API bug into a fund-moving one.

What the report includes

Every verified finding with a reproducible proof-of-concept: the exact request sequence, the role it ran under, and the data or action it reached.

Severity rated on impact in your sector — funds moved, records exposed, tenants crossed — not a generic CVSS guess.

Remediation guidance per finding, written for the team that will implement the fix, plus a re-test window to verify each patch.

Cryptocurrency & Web3 assessment FAQ

Do you test smart contracts?

Our focus is the web and API layer around the platform — wallets, exchanges, custody flows, and integrations. Pure contract audits are a different discipline; we flag boundary issues where contracts meet the web stack.
