TypeScript audits, read line by line.
Source-level security audit of your TypeScript backend, dApp, or SDK. We read the code, follow the data flow, and find the bugs that type checking can't catch.
Types catch bugs. They don’t catch attackers.
TypeScript catches the bugs that look like type errors. It does nothing about race conditions, business logic abuse, or what happens when the data crossing your trust boundary is hostile. A serious TypeScript audit reads the code with the assumption that every input is adversarial — because in production, sometimes it is.
What’s in the audit.
TypeScript-specific risk classes
NestJS, Express, Next.js, Hono, Fastify
Source-level review + runtime testing
Recent TypeScript engagements.
Hyperlines Audit and Pentest
TypeScript audit of the Hyperlines insights marketplace — API surface, business logic, and integration risk.
Initia Protocol Infrastructure
L1 TypeScript infrastructure audit covering the off-chain services around the Initia chain.
Spicenet TypeScript Audit
Source-level TypeScript audit of the Spicenet backend, focused on data flow and auth boundaries.
Scoped to your codebase.
TypeScript audits are sized to LOC, framework complexity, and integration surface. No fixed packages. Talk to us for a scope and quote.
Questions.
A code-level security review of TypeScript application code — backend services, dApp frontends with business logic, indexers, relayers. Source-level depth, not just outside-in pentesting.
Critical paths, yes — auth, payment, signing, state mutations. Lower-risk code gets review proportional to its blast radius. Same approach we use on smart contract audits.
TypeScript audit is source-level (we read the code). Pentest is runtime-level (we attack the running system). Both are valuable; usually you want both — book them together as a combined engagement.
We review the dependency graph for known vulnerabilities, supply-chain risk, and unmaintained packages. Deep audit of the dependency code is out of scope unless you've forked it.
Yes. Wallet SDKs, signing libraries, and integration shims are common scope items. Anywhere user keys or signed payloads flow through TypeScript code.
Two to four weeks for typical scope. Sized to lines of code, framework complexity, and the off-chain/on-chain integration surface.
