okx-dex-swap

What This Skill Does

The okx-dex-swap skill is a specialized agentic capability designed to automate the entire lifecycle of on-chain token swaps. Unlike quote-only tools, this skill manages the complex orchestration of interacting with the OKX DEX Aggregator API (v6). It fetches transaction calldata for optimal swap routes and enables the submission of signed transactions directly to the blockchain. By leveraging this skill, you can automate token-to-token swaps while maintaining robust security via slippage protection, MEV-resistance mechanisms, and optional Jito tip support for high-priority transactions on the Solana network. It simplifies the developer experience by abstracting the handshake between API data retrieval and transaction broadcasting.

Installation

To add this skill to your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/aaronllee/easy-swap

Ensure you have configured your environment variables, including OKX_ACCESS_KEY, OKX_SECRET_KEY, and OKX_PASSPHRASE. For transaction signing, verify that your local environment includes necessary libraries such as web3.py or ethers.js for EVM chains, and solders or @solana/web3.js for Solana transactions.

Use Cases

1. Automated Trading Bots: Build scripts that respond to market price changes by triggering immediate swaps on decentralized exchanges without manual intervention.
2. DeFi Portfolio Rebalancing: Programmatically swap high-volatility assets into stablecoins when specific portfolio allocation thresholds are breached.
3. Cross-Chain Aggregation: Integrate liquidity sourcing across multiple chains into a single interface for seamless asset conversion.
4. Yield Farming Entry: Quickly swap base tokens into liquidity pool tokens to maximize yield opportunities during high-demand windows.

Example Prompts

1. "Swap 500 USDT for ETH on Ethereum using the OKX DEX aggregator, ensuring slippage is set to 0.5% and apply MEV protection."
2. "Perform an exactIn swap of 10 SOL to USDC on the Solana network; please include a Jito tip to ensure the transaction hits the next block."
3. "Execute a swap of 2000 DAI to LINK on BSC, use my current wallet address for signing, and confirm the transaction broadcast status once complete."

Tips & Limitations

• Slippage Management: Always define a reasonable slippage tolerance. Excessive slippage increases the risk of front-running, while too low may cause transactions to revert.
• Wallet Security: Never hardcode your private keys in scripts; use environment-based secrets or hardware wallets for signing.
• Pre-check Approval: Remember that for ERC-20 tokens, you must have approved the router contract to spend your tokens before the swap can succeed.
• Gas Estimates: While the OKX API provides optimized routes, network congestion can still impact execution speed. Ensure sufficient native gas tokens are available in your wallet to cover the final broadcast cost.
