What This Skill Does

The kimchi-premium skill provides a streamlined interface for tracking the 'Kimchi Premium'—a distinct market phenomenon where Bitcoin trades at a higher price on South Korean exchanges (specifically Upbit) compared to global exchanges (specifically Binance). By programmatically fetching real-time ticker data from both platforms, this skill calculates the spread and returns the premium percentage. This is an essential tool for crypto traders operating in the South Korean market, helping them identify arbitrage opportunities or monitor market sentiment shifts that often correlate with retail trading activity in Korea.

Installation

To integrate this skill into your OpenClaw environment, use the provided package management command. Ensure you have Node.js installed in your environment before executing the installation command:

clawhub install openclaw/skills/skills/seungdols/kimchi-premium

After installation, the skill is ready for invocation via the OpenClaw agent interface. No additional API keys are typically required as the skill pulls from public exchange endpoints.

Use Cases

• Arbitrage Monitoring: Quickly identify when the price gap between Upbit and Binance exceeds historical averages, signaling potential entry or exit points for arbitrage traders.
• Sentiment Analysis: Use the premium as a proxy for 'retail FOMO.' A rising Kimchi Premium often indicates heavy buying pressure from South Korean retail investors, which can act as a leading indicator for broader market rallies.
• Risk Management: Avoid overpaying for Bitcoin by checking if the local Korean market is currently overheated compared to global liquidity providers.

Example Prompts

1. "What is the current Bitcoin Kimchi Premium right now?"
2. "Compare the BTC prices on Upbit and Binance and give me the percentage difference."
3. "Is the Kimchi Premium spiking today? Check the latest data."

Tips & Limitations

• Market Hours: Be aware that price volatility can cause rapid fluctuations in the premium; consider looking at the premium over a time-weighted average rather than a single point in time.
• Liquidity: Always verify the trade volume on Upbit before assuming an arbitrage opportunity exists; thin order books may make it difficult to execute large orders at the displayed ticker price.
• Execution Risk: This skill provides data, not execution. Automated arbitrage involves significant risks including exchange transfer times, withdrawal fees, and regulatory restrictions on KRW-based accounts.
