Crypto Exchange & Web3 Security

The Risk

One bug in a smart contract or withdrawal flow and users' funds are gone — permanently, with no chargeback. A single exploit can empty your treasury and end your project overnight.

What We Test

✓ Smart contracts (Solidity, Rust, Move)
✓ Wallets & custody
✓ Deposit / withdrawal logic
✓ Trading engine
✓ KYC / AML flows
✓ Oracles & price feeds
✓ Bridge & cross-chain logic
✓ Admin keys & multisig

What We Find

✓ Reentrancy
✓ Flash-loan attacks
✓ Signature replay
✓ Price / oracle manipulation
✓ Withdrawal race conditions
✓ Private-key exposure
✓ Integer overflow / underflow
✓ Access-control flaws

Outcome

Hard proof your contract and exchange logic hold — before the market tests them for you. Every finding ships with a working proof-of-concept and a code-level fix.

How We Test a Crypto Exchange

A crypto audit covers the smart contracts, the custody, and every flow that moves funds — because one bug means permanent, irreversible loss.

✓ Smart contract audit — reentrancy, flash-loan, overflow, access control
✓ Custody and wallets — private keys, multisig, hot/cold storage
✓ Trading engine — order integrity and market manipulation
✓ Deposit / withdrawal — race conditions and double-spend
✓ Oracles and price feeds — manipulation resistance

Proof for Investors and Regulators

You get a technical audit report with a working proof-of-concept for every critical finding — the kind of evidence investors, listing partners and regulators ask for before trusting your exchange.
