okx-dex-swap

Execute token swaps on-chain via OKX DEX Aggregator API (v6). Use this skill when a user wants to: 1. Build a complete swap flow: get swap calldata -> sign transaction -> broadcast to chain 2. Execute token-to-token swaps with slippage protection, MEV protection, and Jito tips (Solana) 3. Integrate OKX DEX swap + broadcast into applications, bots, or scripts This skill covers the FULL lifecycle: /swap endpoint (get tx data) + /broadcast-transaction endpoint (submit signed tx). For quote-only (no execution), use the okx-dex-quote skill instead.

security

Token security auditing and transaction simulation for OneKey CLI. Use whenever the user asks if a token is safe, wants to check for honeypots, rug pulls, scam tokens, or suspicious contracts, or wants to simulate a transaction before signing. Also triggered as a mandatory pre-check before any swap or trade operation.
