Investigates completed DEX sandwich-style MEV from public blocks and bundles—front-victim-back ordering on EVM and Solana, Jito bundle traces, swap decoding, victim slippage vs searcher profit estimates, and evidence-style case studies. Use when the user asks for sandwich attack analysis, MEV sandwich post-mortems, high-slippage swap forensics, or searcher clustering—not for building sandwich bots, mempool manipulation for profit, or harassing labeled wallets.
Complete authentication guide for Orderly Network - EIP-712 wallet signatures for EVM accounts, Ed25519 message signing for Solana accounts, and Ed25519 signatures for API requests
Use when the user asks anything about blockchain wallets, transactions, signing, token transfers, supported chains, wallet balances, perpetual futures trading, prediction markets, token swaps, cross-chain bridges, market data, token discovery, decoding EVM calldata, DeFi earn/yield vaults, or authentication via the MetaMask Agentic CLI; also when an HTTP request returns 402 Payment Required / x402 or the agent needs to pay for a paywalled API, endpoint, file, or resource over HTTP. Single entry point for all mm CLI operations.
Trace cryptocurrency addresses and transactions on public blockchains using block explorers like Etherscan, Blockchair, mempool.space and Blockscout. Use when following a Bitcoin, Ethereum or EVM wallet, investigating a ransom or scam payment, clustering addresses with common-input heuristics, resolving an ENS name, identifying exchange deposit addresses, mixers, CoinJoin, Tornado-style pools or cross-chain bridges, or checking an address against OFAC sanctions listings.
Write SQL, TypeScript, and dynamic table transforms for Goldsky Turbo pipelines. Use this skill for: decoding EVM event logs with _gs_log_decode (requires ABI) or transaction inputs with _gs_tx_decode, filtering and casting blockchain data in SQL, combining multiple decoded event types into one table with UNION ALL, writing TypeScript/WASM transforms using the invoke(data) function signature, setting up dynamic lookup tables to filter transfers by a wallet list you update at runtime (dynamic_table_check), chaining SQL and TypeScript steps together, or debugging null values in decoded fields. For full pipeline YAML structure, use /turbo-pipelines instead. For building an entire pipeline end-to-end, use /turbo-builder instead.
MANDATORY — invoke this skill BEFORE making any Blockscout MCP tool calls or writing any blockchain data scripts, even when the Blockscout MCP server is already configured. Provides architectural rules, execution-strategy decisions, MCP REST API conventions for scripts, endpoint reference files, response transformation requirements, and output conventions that are not available from MCP tool descriptions alone. Use when the user asks about on-chain data, blockchain analysis, wallet balances, token transfers, contract interactions, on-chain metrics, wants to use the Blockscout API, or needs to build software that retrieves blockchain data via Blockscout. Covers all EVM chains.
Look up metadata for any Injective token or denom. Resolves native tokens (INJ), Peggy ERC-20 bridged tokens (USDT, USDC, WETH), IBC assets (ATOM, OSMO), TokenFactory tokens, and EVM ERC-20s to their human-readable symbol, decimals, and type. Also supports sending tokens between addresses and depositing/withdrawing from trading subaccounts. Requires the Injective MCP server to be connected.
Use when user asks about blockchain data or building Web3 applications — token balances, NFT ownership, transaction history, ENS resolution, on-chain statistics, JSON-RPC calls, webhooks, real-time monitoring, or any Nodit API integration across EVM, Solana, Sui, Aptos, and other chains
Use this skill when writing, reviewing, auditing, or deploying Solidity smart contracts. Triggers on Solidity development, smart contract security auditing, DeFi protocol patterns, gas optimization, ERC token standards, reentrancy prevention, flash loan attack mitigation, Foundry/Hardhat testing, and blockchain deployment. Covers Solidity, OpenZeppelin, EVM internals, and common vulnerability patterns.
Use for Cobo Agentic Wallet operations via the `caw` CLI: wallet onboarding, token transfers (USDC, USDT, ETH, SOL, etc.), smart contract calls, balance queries, and policy denial handling. Covers DeFi execution on EVM (Base, Ethereum, Arbitrum, Optimism, Polygon) and Solana: Uniswap V3 swaps, Aave V3 lending, Jupiter swaps, DCA, grid trading, Polymarket, and Drift perps. Use when: user mentions caw, cobo-agentic-wallet, MPC wallet, TSS node, Cobo Portal, agent wallet, or needs any crypto wallet operation — even without explicit "Cobo" mention. NOT for: fiat payments, bank transfers, or crypto-to-fiat off-ramp.

Use when the task spans multiple topics or the user needs help picking which named skill to load.
Gas optimization patterns for Solidity smart contracts. Use when optimizing contract deployment costs, runtime gas usage, or storage efficiency. Covers storage packing, custom errors, immutable variables, calldata optimization, loop patterns, assembly usage, and Solady gas-optimized alternatives. Triggers on tasks involving gas optimization, storage layout, deployment cost reduction, or EVM efficiency.
