What problem does it solve? Monitoring what profitable wallets, KOLs, and whales are buying on-chain requires manually watching dozens of addresses across multiple chains. This Skill aggregates that activity into transaction feeds, buy-only signal alerts, and ranked trader leaderboards through the OKX Onchain OS CLI. ## Core Features & Use Cases - Address Tracker: Fetch raw DEX transaction feeds for smart money, KOL, or up to 20 custom wallet addresses, with filters for trade direction, chain, volume, market cap, liquidity, and holder count. - Aggregated Buy Signals: Retrieve buy-only signal alerts showing which tokens are being collectively bought by smart money, KOLs, or whales, including trigger wallet count and sold ratio. - Trader Leaderboard: Rank top traders by PnL, win rate, transaction count, volume, or ROI across time frames from 1 day to 3 months, with wallet-type filters like sniper, dev, or fresh wallets. - WebSocket Protocol Reference: Build real-time subscription clients for the OKX DEX WebSocket using the documented authentication, channel, and heartbeat specifications. - Use Case: Ask "what are smart money buying on Solana" to get a live transaction feed, then drill into a token's signals and buy it through the swap workflow. ## Quick Start Ask the agent to show what smart money wallets are buying on Solana and it will run the tracker command and present the trade feed.
