Audit Services

Four dimensions that cover the real attack surface

From on-chain contracts to off-chain infrastructure, attackers only need the weakest link. We audit your project as one complete system: smart contracts, business and economic model, off-chain infrastructure, and black-box penetration. Senior security experts lead the judgment; umibit AI guarantees the coverage.

Smart-Contract White-Box AuditCore

Contract code is the first thing an attacker targets. Working against the source, we review the contract logic line by line: access control and privileges, reentrancy, integer arithmetic, external calls, event and state consistency, upgradeability, Gas, and logical correctness. umibit AI runs a high-coverage first pass; senior security experts then confirm exploitability finding by finding and write the PoC.

Missing access control / incorrect modifiers	AI
Reentrancy (ERC-777 callbacks, fee-on-transfer + external calls)	AI人工
Integer overflow / underflow, unchecked blocks	AI
Unchecked external call return values, low-level call	AI
approve race conditions / allowance management	AI人工
Upgradeable contracts / proxies: can the logic be silently swapped	AI人工

Business Logic & Economic Model AuditThe Costliest Trap

The most expensive flaws are rarely in the syntax — they're in the design, where AI struggles and senior security experts make the call by hand: whether the protocol's design intent matches the implementation, whether token economics and incentives open arbitrage or manipulation paths, oracle / flash-loan / MEV risk, and centralization risk in governance and privileges.

Gaps between design intent and code implementation	人工
Arbitrage and manipulation paths in token economics / incentive mechanisms	人工
Reflection / fee-on-transfer rounding and compatibility with external protocols	人工
Liquidity: whether the LP is locked and whether the pool can be pulled in a rug	人工
Oracle dependence / flash-loan / MEV risk	人工
Centralization risk in governance and critical privileges	人工

Off-Chain Infrastructure SecurityThe Overlooked Link

The attack surface beyond the contract is just as deadly: backend services and API authentication, key management, admin panels, RPC node configuration. We audit on-chain and off-chain as one system, so you never end up with "a perfectly safe contract and a stolen private key."

Backend services and API authentication / privilege escalation	AI人工
Key management and signing services	人工
Admin panels and operations privileges	AI人工
RPC nodes and infrastructure configuration	AI人工
Key leakage / hardcoded credential scanning	AI

Black-Box / Penetration TestingThe Attacker's View

From the attacker's vantage point, without relying on source code, we test the attack surface of deployed systems, the dApp front end, and public interfaces. Deterministic probes prioritize precision; recall is handed to a controlled autonomous agent. Requires the client's written authorization.

dApp front-end and public API attack surface	AI人工
Reconnaissance / exposure surface and configuration weaknesses	AI
Probes for web vulnerabilities such as injection / privilege escalation / SSRF	AI
Deep exploitation validation by an autonomous penetration agent	AI人工

Compliance Note

Black-box / penetration testing actively probes deployed systems, the dApp front end, and public interfaces, and is carried out only after written client authorization. Autonomous exploitation validation runs entirely within a controlled scope and issues no requests beyond the authorized boundary.

Put your contracts in the hands of an audit that holds up to verification

Tell us your contract scope and time window, and we'll provide an audit plan and quote. The final report carries the version, contract address, and date — so anyone can independently verify it.
