Security audit and code review checklist. Covers 30+ vulnerability types with real-world exploit cases (2021-2026) and EVMbench Code4rena patterns. Use when conducting security audits, code reviews, or pre-deployment security assessments.
Build USDC bridging with Circle Bridge Kit SDK and Crosschain Transfer Protocol (CCTP). Supports bridging USDC between EVM chains, between EVM chains and Solana, and between any two chains on Circle Wallets (i.e Developer-Controlled Wallets or Programmable wallets). Use when: bridge USDC, setting up Bridge Kit adapters (Viem, Ethers, Solana Kit, Circle Wallets), handling bridge events, collecting custom fees, configuring transfer speed, or using the Forwarding Service. Triggers on: Bridge Kit, bridge USDC, crosschain transfer, CCTP, move USDC between chains, @circle-fin/bridge-kit, adapter-viem, adapter-ethers, adapter-solana-kit, forwarding service, bridge routes.
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.
Integrate EVM blockchains using viem. Use when user says "read blockchain data", "send transaction", "interact with smart contract", "connect to Ethereum", "use viem", "use wagmi", "wallet integration", "viem setup", or mentions blockchain/EVM development with TypeScript.
Deep EVM smart contract security audit system. Use when asked to audit a contract, find vulnerabilities, review code for security issues, or file security issues on a GitHub repo. Covers 500+ non-obvious checklist items across 19 domains via parallel sub-agents. Different from the security skill (which teaches defensive coding) — this is for systematically auditing contracts you didn't write.
Integrate Circle Gateway to hold a unified USDC balance across multiple blockchains and transfer USDC instantly (<500ms) via permissionless deposit, burn, and mint workflows. Available on 11 EVM chains + Solana (mainnet and testnet), plus Arc testnet. Use when: enabling chain-agnostic user experiences, low-latency or instant next-block finality is required, capital needs to be pooled across chains for greater capital efficiency, or building apps with consolidated crosschain balances. Triggers on: Gateway, unified balance, crosschain USDC, instant transfer, chain abstraction, Gateway Wallet, Gateway Minter, gatewayMint, burn intent, crosschain liquidity, payment routing, capital efficiency, permissionless transfer.
Smart contract vulnerability playbook. Use when auditing Solidity/EVM contracts for reentrancy, integer overflow, access control, delegatecall, flash loan, signature replay, and MEV-related attack patterns.
Points to Christoph Michel’s (cmichel.io) long-form guide on becoming a smart contract security auditor—EVM-centric learning path, CTFs, canonical DeFi contracts, finance basics, and an FAQ (tools, scoping, compensation). Use when the user asks how to start in Solidity/EVM auditing or cites this article—not as current salary data, job placement advice, or a substitute for hands-on practice and primary documentation.
Operate Moralis EVM wallet and token reads through UXC with a curated OpenAPI schema, API-key auth, and wallet-intelligence guardrails.
Pay for x402-protected API endpoints with USDC. Use when calling APIs that return HTTP 402 Payment Required, integrating payments into agents, handling x402 payment requirements, building autonomous agents that pay for API access, or discovering paid services via Bazaar. Supports EVM (Base, Ethereum, Avalanche) and Solana networks.
Master Ethereum development including EVM, gas optimization, and client interactions
REST API for optimized token swapping (including executable transaction generation), swap quoting, and pricing using the SushiSwap Aggregator. Use this skill when the user wants to: - Get a swap quote between two tokens on 40+ evm networks - Generate executable swap transaction data - Fetch token prices for a specific network or token - Retrieve token metadata - Discover supported AMM liquidity sources - Integrate SushiSwap swapping or pricing logic via HTTP/REST (and not the SushiSwap Javascript API)
