Web3 & DeFi Pentesting & VAPT
Smart contract audits, dApp pentesting and bridge security for DeFi, NFT and Web3 infrastructure.
On-chain bugs are unfixable once deployed. StartSecure combines manual smart contract audits (Solidity, Vyper, Rust) with off-chain dApp, oracle and bridge pentesting — so the whole stack, not just the contract, is hardened before launch.
Attack patterns specific to Web3 & DeFi
Re-entrancy & arithmetic bugs
Classic and cross-function re-entrancy, unchecked low-level calls, integer over/underflow.
Bridge & oracle manipulation
Validator collusion, message-replay across chains, oracle price manipulation.
Front-end / wallet drainer paths
Compromised RPCs, malicious approvals, signature-phishing flows, EIP-712 abuse.
Off-chain infra attacks
Sequencer, indexer, relayer and admin-key compromise.
Our web3 & defi testing approach
Manual smart contract audit
Line-by-line review by senior auditors; we benchmark against Trail of Bits / OpenZeppelin rigor.
Economic & game-theory analysis
Flash-loan, MEV, governance-attack and incentive-misalignment scenarios modeled.
Off-chain dApp pentest
Web/mobile dApp UI, RPC nodes, indexer APIs and admin tooling included.
What you get
- Audit reports recognized by tier-1 launchpads, exchanges and underwriters.
- Reduced bug-bounty severity post-launch.
- Full stack coverage — contract, dApp and infra — in one engagement.
