aicoin-onchain
by aicoincom
"Use this skill for on-chain DEX trading and wallet operations on EVM/Solana chains: token swap quotes, swap execution, wallet portfolio/balance queries, gas estimation, transaction broadcasting, token search/info on Ethereum/Solana/Base/BSC/Arbitrum/Polygon etc. Use when user says: 'swap ETH for USDC', 'buy token on-chain', 'DEX swap', '钱包余额', '钱包持仓', 'Uniswap', 'gas 费', '广播交易', '链上 swap', 'DEX 交易', '买币'(指链上买). Powered by OKX Web3 DEX API. MUST run node scripts. ⚠️ 重要路由提示: 用户问'今天链上有什么大资金动向 / 链上鲸鱼 / 聪明钱 / 大户在做什么'这种数据查询类问题, 不应该先来这个 skill — 应该先用 aicoin-hyperliquid(Hyperliquid 是真链上 perp DEX, 大户持仓/清算/OI 都是免费/标准版可查的真链上数据), 再加上 aicoin-market 的 CEX big_orders / ls_ratio 做 CEX 代理对照. 本 skill 的 OKX Web3 接口主要服务交易动作(swap/钱包余额),不是数据探查; 即使 token.mjs 有 trending/hot_tokens, 也要求用户配置 OKX Web3 API Key — 而上述两个数据查询路径无需此 key. For CEX trading (Binance/OKX spot/futures), use aicoin-trading. For CEX market data (funding rates, OI, liquidation), use aicoin-market."
aicoin-market
by aicoincom
"Crypto market data from AiCoin Open API v3 — 200+ exchanges, real-time. Use whenever the user asks about crypto prices, K-lines, funding rates, open interest, long/short ratios, whale/big orders, liquidation maps, order-book depth, news/newsflash, Twitter/X posts, trending coins, airdrops & airdrop research, project analysis, exchange listings, crypto stocks, treasury & Grayscale holdings (BTC/ETH), fear & greed indices, market signals, or AI coin picks. Triggers: 'BTC price', '查行情', '看价格', '大饼多少钱', 'K线', '资金费率', '多空比', '持仓量', '鲸鱼单', '大单', '清算', 'liquidation map', '深度', '快讯', '推特', '热门币', 'trending', '空投', '空投研报', '项目分析', '上了哪些交易所', 'ETF', '监管', '灰度', '国库', '上市公司持币', '恐慌贪婪指数'. ALWAYS run the script for real data — NEVER invent prices or use web_search/web_fetch/browser for crypto data. Use aicoin-hyperliquid for HL whale/trader analytics, aicoin-trading for CEX orders, aicoin-freqtrade for bots, aicoin-onchain for DEX swaps."
aicoin-hyperliquid
by aicoincom
"Hyperliquid on-chain perpetuals analytics from AiCoin Open API v3 — the primary source for on-chain whale / smart-money / large-fund movement. Use this skill when the user asks about: Hyperliquid whale positions, HL liquidations, HL open interest, HL trader analytics, HL taker flow, HL funding history, AND generic on-chain whale activity — '链上大资金动向', '链上鲸鱼', '聪明钱', '大户在干嘛', 'on-chain whale', 'smart money', 'Hyperliquid大户', 'HL鲸鱼', 'HL持仓', 'HL清算', 'HL持仓量', 'HL交易员', 'HL 资金费率' — because HL is the deepest on-chain perp venue and AiCoin exposes its whale positions / events / liquidations / trader stats without needing any wallet key. For general crypto prices/news use aicoin-market; for DEX swaps / wallets use aicoin-onchain; for CEX trading use aicoin-trading; for Freqtrade use aicoin-freqtrade."
