Develop secure smart contracts using OpenZeppelin Contracts libraries. Use when users need to integrate OpenZeppelin library components — including token standards (ERC20, ERC721, ERC1155), access control (Ownable, AccessControl, AccessManager), security primitives (Pausable, ReentrancyGuard), governance (Governor, timelocks), or accounts (multisig, account abstraction) — into existing or new contracts. Covers pattern discovery from library source, MCP generators, and library-first integration. Supports Solidity, Cairo, Stylus, and Stellar.
Deploy contracts to SKALE chains. Covers chain selection, RNG, bridge, deployment setup. Use for deploying smart contracts to SKALE.
Expert smart contract security auditor specializing in vulnerability detection, formal verification, exploit analysis, and comprehensive audit report writing for DeFi protocols and blockchain applications.
Provides domain knowledge and guidance for the Flare Data Connector (FDC)—attestation types, request flow, Merkle proofs, verifier/DA Layer, and smart contract integration. Use when working with FDC, cross-chain attestations, EVMTransaction, Web2Json, Payment, AddressValidity, XRPPayment, XRPPaymentNonexistence, proof-of-reserves, weather insurance, or Flare Developer Hub FDC guides and starter repos.
Adversarial security audit playbook for Plutus V3 Aiken DEX contracts (threat model, invariants, findings, tests, tx repro shapes).
Build and test Solidity smart contracts with Foundry toolkit. Use when developing Ethereum contracts, writing Forge tests, deploying with scripts, or debugging with Cast/Anvil. Triggers on Foundry commands (forge, cast, anvil), Solidity testing, smart contract development, or files like foundry.toml, *.t.sol, *.s.sol.
Work with NFDomains (NFDs), the Algorand Name Service (.algo domains), using the @txnlab/nfd-sdk TypeScript SDK. Use when building features that involve resolving .algo domain names to addresses (or reverse), displaying NFD avatars and metadata, searching for NFDs, minting new NFDs, purchasing NFDs from the marketplace, managing NFD metadata and linked addresses, working with NFD segments (subdomains), interacting with NFD vaults, or integrating NFD name resolution into Algorand applications.
Configure session keys and policies for Cartridge Controller to enable gasless, pre-approved transactions. Use when defining contract interaction policies, setting spending limits, configuring signed message policies, or implementing error handling for session-based transactions. Covers SessionPolicies type, policy definitions, verified sessions, and error display modes.
Add an ERC-721 NFT contract to a Scaffold-ETH 2 project. Use when the user wants to: create an NFT collection, deploy an ERC-721, add NFT minting, build an NFT gallery or transfer UI, or work with non-fungible tokens in SE-2.
Generates secure Aptos Move V2 smart contracts with Object model, Digital Asset integration, security patterns, and storage type guidance. Includes comprehensive storage decision framework for optimal data structure selection. Triggers on: 'write contract', 'create NFT collection', 'build marketplace', 'implement minting', 'generate Move module', 'create token contract', 'build DAO', 'implement staking'. Ask storage questions when: 'store', 'track', 'registry', 'mapping', 'list', 'collection'.
Audits Move contracts for security vulnerabilities before deployment using 7-category checklist. Triggers on: 'audit contract', 'security check', 'review security', 'check for vulnerabilities', 'security audit', 'is this secure', 'find security issues'.
Reference for Uniswap V3/V4 concepts used in Doppler development, including tick math, sqrtPriceX96, concentrated liquidity formulas, and V4 hooks/singleton architecture.
