Review and write Solidity smart contracts with security in mind. Address reentrancy, where external calls trigger repeated execution, along with numeric overflow and access control issues, using implementation patterns, security tests, and documentation for audit preparation.
Audit Solidity contracts in Foundry projects before deployment using code analysis, randomized tests, manual review, and private key checks. Produces a JSON report with findings, remediation, test coverage, and a pass or fail deployment decision.
Analyze Solidity smart contracts with Slither and Mythril before Ethereum deployment. Combine code inspection with execution path analysis, review potential vulnerabilities, remove duplicate findings, and produce an audit report with severity ratings and suggested fixes.

Pre-deployment security audit of Solidity smart contracts in a Foundry project. Combines static analysis (Slither, Aderyn), symbolic execution (Mythril), and property-based testing (forge fuzz + invariant tests with handlers) to catch reentrancy, access-control, oracle/price manipulation, and arithmetic bugs BEFORE deploying to an EVM chain. Also enforces key hygiene (no plaintext private keys, encrypted cast keystore) and a secure deploy workflow. Use when writing, reviewing, testing, or deploying Solidity/Foundry contracts, building a dApp, or working with forge/cast/anvil, MetaMask, or Web3/DeFi code.

Review Solidity automated market makers, liquidity pools, and token swaps using security checklists and safer code examples. Check repeated calls during transfers, manipulated prices, share calculations, swap limits, and administrator permissions.
Provides a reference for reviewing DeFi smart contracts, programs that manage blockchain transactions. It organizes vulnerability types with causes, code examples, search patterns, and fixes to help investigate accounting, permissions, boundary conditions, and pricing logic.
Smart contract security audit — 10 DeFi bug classes (accounting desync, access control, incomplete path, off-by-one, oracle, ERC4626, reentrancy, flash loan, signature replay, proxy), pre-dive kill signals (TVL < $500K etc), Foundry PoC template, grep patterns for each class, and real Immunefi paid examples. Use for any Solidity/Rust contract audit or when deciding whether a DeFi target is worth hunting.

Smart contract and Web3 security audit skill for Solidity, Vyper, Move, and Cairo. Covers reentrancy, access control, oracle manipulation, MEV/sandwich exposure, signature replay, upgrade safety, ERC token edge cases, bridge risk, and DeFi invariants. Tooling includes Slither, Mythril, Echidna, Foundry, Halmo, Certora, and custom invariant tests. Use for design review, code audit, and incident analysis on contracts you own or are authorized to assess.

Use when a task needs the judgment of a Blockchain Engineer — applying the checks-effects-interactions pattern to prevent a reentrancy exploit, auditing a privileged/administrative function for missing access control, designing a manipulation-resistant oracle for on-chain price data, minimizing gas cost through storage-write design, or deciding whether a smart contract needs an upgradability pattern before deployment.
