Upgrade Stylus smart contracts using OpenZeppelin proxy patterns on Arbitrum. Use when users need to: (1) make Stylus Rust contracts upgradeable with UUPS or Beacon proxies, (2) understand Stylus-specific proxy mechanics (logic_flag, WASM reactivation), (3) integrate UUPSUpgradeable with access control, (4) ensure storage compatibility across upgrades, or (5) test upgrade paths for Stylus contracts.
Ethereum token and protocol standards — ERC-20, ERC-721, ERC-1155, ERC-4337, ERC-8004, and newer standards. When to use each, how they work, key interfaces. Use when building tokens, NFTs, or choosing the right standard for a project.
Verified contract addresses for major Ethereum protocols across mainnet and L2s. Use this instead of guessing or hallucinating addresses. Includes Uniswap, Aave, Compound, Aerodrome, GMX, Pendle, Velodrome, Camelot, SyncSwap, Lido, Rocket Pool, 1inch, Permit2, MakerDAO/sDAI, EigenLayer, Across, Chainlink CCIP, Yearn V3, USDC, USDT, DAI, ENS, Safe, Chainlink, and more. Always verify addresses against a block explorer before sending transactions.
Solidity security patterns, common vulnerabilities, and pre-deploy audit checklist. The specific code patterns that prevent real losses — not just warnings, but defensive implementations. Use before deploying any contract, when reviewing code, or when building anything that holds or moves value.
Smart contract and secure API contract security analysis — invariant checking, access control, reentrancy, and integer overflow patterns. Implements Checks-Effects-Interactions pattern, formal invariant verification, and OpenSCV vulnerability taxonomy for Solidity/EVM and Rust/Solana contracts.
Guide for integrating Ika dWallet 2PC-MPC protocol into Sui Move contracts. Use when building Move contracts that need cross-chain signing, dWallet creation, presigning, signing, future signing, key importing, or any Ika on-chain integration. Triggers on Move/Sui contract tasks involving dWallets, cross-chain signing, or Ika protocol operations.
Create production grade smart contracts. Use this skill when the user asks to write smart contracts, specially if they are going to be deployed to production (to a mainnet, or used in a mainnet script).

Expert guidelines for Ethereum smart contract development with Solidity, OpenZeppelin, and Hardhat
Detects and modernizes outdated Move V1 syntax, patterns, and APIs to Move V2+. Use when upgrading legacy contracts, migrating to modern syntax, or converting old patterns to current best practices. NOT for writing new contracts (use write-contracts) or fixing bugs.
Token and address risk assessment. Use this skill whenever the user asks about token, contract, or address safety. Trigger phrases include: is this token safe, check contract risk, is this address safe, honeypot, rug. MCP tools: info_compliance_check_token_security, info_coin_get_coin_info; Address mode: info_onchain_get_address_info.
Design Solana/Anchor instructions with clear inputs, constraints, authority checks, and invariants. Use when defining or reviewing instruction APIs.
