Use when running Slither static analysis on Solidity contracts. Covers running slither, key detectors, false positive filtering, severity levels, upgradeability checks, CI integration, and triage methodology.
Core Solidity design patterns for safe, maintainable smart contracts. Use when writing new contracts, reviewing architecture, or refactoring existing protocol code. Covers checks-effects-interactions, pull-over-push, guard checks, state machines, access…
Security-focused Solidity development patterns. Use when writing contracts that handle funds, interact with external tokens, or accept user input. Covers reentrancy guards, SafeERC20, access control, input validation, integer safety, and safe external calls.
Use when implementing staking contracts, reward distribution systems, or yield farming. Covers the Synthetix reward model, per-second accrual, cooldown periods, and boosted reward mechanics.
EVM storage layout expertise for struct packing, proxy storage patterns, and collision avoidance. Use when designing data structures, working with upgradeable proxies, optimizing storage costs, or debugging storage-related issues.
Use when building or maintaining The Graph subgraphs. Covers subgraph.yaml manifest, schema.graphql design, AssemblyScript mappings, event handlers, data source templates, testing with matchstick, deployment, and indexing optimization.
Use when setting up test environments for Solidity protocols. Covers mock contracts, fork-based fixtures, shared setUp, factory patterns, token deployments, and reusable test helpers.
Time-based vulnerability patterns and safe usage for Solidity contracts. Use when implementing unlock schedules, cooldowns, auctions, or any time-dependent logic. Covers block.timestamp manipulation, epoch boundary attacks, and safe time patterns.
Use when implementing bonding curve token sales, automated market makers with supply-dependent pricing, or continuous token models. Covers linear, polynomial, logarithmic, and Bancor-style curves.
Safe integration patterns for non-standard ERC-20 tokens. Use when building protocols that accept arbitrary tokens. Covers USDT (no return value), USDC (6 decimals, blacklist), fee-on-transfer, rebasing tokens, ERC-777 callbacks, pausable tokens, and Permit2.
Upgrade vulnerability detection and prevention for Solidity proxy contracts. Use when implementing UUPS, Transparent, or Diamond proxy patterns. Covers uninitialized proxy attacks, storage collisions, selector clashing, and upgrade safety validation tools.
Use when integrating USDC into smart contracts, handling stablecoin transfers, approvals, or checking balances. Covers the 6-decimal rule, production contract addresses on all major chains, native vs bridged USDC variants, FiatTokenV2_2 proxy architecture,…
Use when integrating wallets into dApps. Covers WalletConnect, injected providers, EIP-1193, account abstraction (EIP-4337, EIP-7702), Safe SDK, multi-sig interaction, hardware wallets, and network switching.
Use when building ERC-4626 tokenized vaults, yield aggregators, or share-based deposit/withdraw systems. Covers share math, rounding, first depositor attack mitigation, and complete implementation patterns.
