StarkNet Cairo ZK-Proof Audit Trail Service

In-depth security review of your Cairo 1.0 contracts, focusing on ZK-specific vulnerabilities, arithmetic overflows, and storage logic. We deliver a detailed report with actionable fixes and gas optimization recommendations.

We architect and implement the end-to-end proof generation pipeline for your application's state transitions. This includes STARK proof batching, recursive proof aggregation, and on-chain verification contract deployment.

Every state change, proof, and transaction is cryptographically hashed and anchored to a public ledger (e.g., Ethereum L1). This creates a permanent, tamper-proof record for compliance, dispute resolution, and investor reporting.

Tailored integration of Cairo's prover (e.g., Stone, Lambdaworks) into your application's backend. We handle the complexity of proof computation, witness generation, and managing prover infrastructure at scale.

Structure your audit trail to meet specific regulatory requirements (MiCA, Travel Rule). We map on-chain proofs to off-chain legal entities and generate standardized compliance reports from the immutable log data.

Continuous analysis of your proof generation costs and latency. We implement strategies like proof recursion, state diffs, and efficient Merkle tree updates to reduce operational expenses by up to 60%.

We conduct a deep-dive analysis of your Cairo contracts and business logic to design a comprehensive audit trail strategy. We define the critical events, state transitions, and proof requirements that must be immutably logged.

Our engineers integrate non-invasive logging calls directly into your Cairo codebase. We emit structured events for every critical function and state change, ensuring zero impact on core contract logic or gas efficiency.

We deploy and configure our off-chain prover service to consume emitted events, generate STARK proofs of state transitions, and index them into a queryable database. This creates an immutable, verifiable chain of custody.
