Atomic lend-execute-verify pattern for MultiversX smart contracts. Use when building flash loans, atomic swaps, temporary grants, or any operation that lends assets, executes a callback, and verifies repayment within a single transaction.
Audit and assurance advisory skill for consulting engagements. Use when preparing audit readiness assessments, control environment evaluations, SOC reporting guidance, ESG assurance readiness, or stakeholder materials for audit partners, audit committees, CFOs, and internal audit directors.
TypeScript library for NEAR Protocol blockchain interaction. Use this skill when writing code that interacts with NEAR Protocol, including viewing contract data, calling contract methods, sending NEAR tokens, building transactions, creating type-safe contract wrappers, integrating wallets (Wallet Selector, HOT Connect), React hooks and providers (@near-kit/react), managing keys, testing with sandbox, meta-transactions (NEP-366), and message signing (NEP-413).
Analyze compiled WASM binaries for size optimization, panic analysis, and debugging with DWARF symbols. Use when troubleshooting contract deployment issues, optimizing binary size, or debugging runtime errors.
Production-grade project structure patterns for MultiversX smart contracts. Use when starting a new contract project, refactoring an existing one, or building multi-contract systems with shared code.
Complete security audit methodology for MultiversX smart contracts. Covers context building, entry point analysis, static analysis patterns, and automated Semgrep scanning. Use when performing security audits, code reviews, or setting up automated vulnerability detection.
Cryptographic operations in MultiversX smart contracts. Use when hashing data (SHA256, Keccak256, RIPEMD160), verifying signatures (Ed25519, secp256k1, secp256r1, BLS), or encoding signatures in on-chain logic.
Make cross-contract calls in MultiversX smart contracts. Use when calling another contract, handling callbacks, managing back-transfers, using typed proxies, or sending tokens via the Tx builder API (.tx().to()).
Read on-chain state in MultiversX smart contracts. Use when accessing caller info, account balances, block timestamps, ESDT token metadata, local roles, code metadata, or any data from self.blockchain().
Gas-optimized cache patterns for MultiversX smart contracts using Drop-based write-back caches. Use when building contracts that read/write multiple storage values per transaction, DeFi protocols, or any gas-sensitive contract.
Validates smart contract audit findings against platform-specific judging criteria. Predicts acceptance likelihood, scores quality, flags automatic invalidators, and generates a detailed Validation-Report.md. Use when asked to validate, score, or predict acceptance of audit findings, bug reports, or security research writeups before submission. Supports Code4rena, Sherlock, Cantina, HackenProof, and generic criteria.
Comprehensive code analysis toolkit for MultiversX smart contracts. Covers differential review (version comparison, upgrade safety), fix verification (validate patches, regression testing), and variant analysis (find similar bugs across codebase). Use when reviewing PRs, verifying security patches, or hunting for bug variants.
