We have privacy-preserving smart contracts built on Inco Network (FHE-enabled blockchain) and need a thorough independent review before mainnet deployment. The main priorities are uncovering security vulnerabilities specific to encrypted state handling and verifying correct implementation of confidential computing patterns; gas optimization is secondary. Here is what we need from you: • Manual and automated analysis of Solidity source code using tools such as Slither, Foundry test suites, or similar — adapted for privacy-focused contract logic. • Testing of edge cases related to encrypted variables, access control for confidential data, and proper handling of FHE operations. • Verification that sensitive data remains encrypted throughout contract execution and cannot be leaked through transaction metadata or events. • A concise PDF/Markdown report detailing every issue by severity, exact code locations, and practical remediation guidance. • A summary document confirming the contract meets Inco Network's privacy standards and best practices. All code and findings must remain strictly confidential. We're looking for someone who can work efficiently while maintaining thoroughness. Please share your relevant experience with privacy tech, ZK, or FHE-related projects if applicable.

Hi there, I will perform a thorough security audit of your privacy-focused Solidity contracts for Inco Network, with emphasis on encrypted state handling and correct confidential computing patterns. My approach combines manual review and automated checks: adapting Slither and Foundry test suites to stress encrypted variables, access control for sensitive data, and FHE-related logic. I’ll validate that confidentiality is preserved during contract execution and that no leakage can occur through transaction metadata or events, and I’ll run edge-case tests around key management, randomization, and possible side-channel vectors. You’ll receive a concise PDF/Markdown report detailing issues by severity, exact code locations, and practical remediations, plus a short summary confirming alignment with Inco Network privacy standards and best practices. All findings will be strictly confidential, with clear remediation steps and risk posture. Do you have a formal privacy standards document or threat model you want us to align to, and can you share the current test vectors for the FHE operations in your contracts? Best regards,

Hi, This is Elias from Miami. I’ve reviewed your request and understand you need an independent pre-mainnet security review of Solidity contracts on Inco (FHE-enabled), with the main focus on privacy-specific risks: encrypted state handling, confidential computing patterns, access control around confidential data, and ensuring nothing leaks via events/metadata. Gas tuning is secondary. I’m interested because privacy contracts fail in different ways than “normal” DeFi: it’s not just reentrancy and auth — it’s also encryption lifecycle mistakes, accidental plaintext surfaces, unsafe event usage, and edge-case behavior around FHE ops and permissioned decrypt paths. I can run automated tooling (Slither + custom rules, Foundry tests/fuzzing) and do a deep manual review tailored to FHE flows. Deliverables: concise PDF/Markdown report with severity, exact code locations, exploit narrative where relevant, and practical fixes, plus a final privacy-standards checklist / sign-off summary aligned to Inco best practices. -Q1 Are you using Inco’s standard FHE libraries/types (and which versions), or any custom encryption wrappers that also need review? -Q2 Do contracts emit any events tied to encrypted values (even hashed/packed), and do you have an explicit “no-sensitive-event” policy to enforce? -Q3 What is the threat model for decrypt/access: who can request decrypt, how is authorization enforced on-chain, and are there admin/upgrade keys involved? Regards.

I can run an independent security review of your Solidity contracts on Inco Network with focus on encrypted state and FHE handling. I’ll combine manual review with Slither plus a Foundry test suite to hit privacy specific edge cases. I will specifically check that sensitive values stay encrypted end to end and are not leaked through events or transaction metadata. Access control around confidential data and any decryption or reveal pathways will be stress tested. I’ve reviewed privacy focused smart contract logic where the main risks were side channels and incorrect state handling. A common risk is subtle leakage in logs or revert reasons, so I will flag and patch those patterns early. You’ll get a clear PDF or Markdown report with severity, exact locations, and fixes, plus a short privacy standards summary. Can you share the repo and any Inco specific privacy guidelines you want me to benchmark against?

Hi, I will conduct a thorough security audit of your Inco Network privacy-preserving smart contracts, covering manual code review, automated analysis with Slither and Foundry, FHE-specific edge case testing, and encrypted state handling verification. The deliverable will be a detailed PDF report with severity-rated findings, exact code locations, and remediation guidance. For FHE-enabled contracts specifically, I will focus on verifying that encrypted variables never leak through event emissions, return values, or storage slot patterns. This is a common vulnerability in confidential computing contracts where the logic is correct but metadata exposure undermines the privacy guarantee. Questions: 1) How many contracts and approximately how many lines of Solidity are in scope for this audit? 2) Do you have an existing Foundry test suite I can extend, or should I write the test cases from scratch? Looking forward to your response. Best regards, Kamran
