AiCoin Onchain
On-chain DEX toolkit powered by OKX Web3 DEX API. Token discovery, swap execution, wallet portfolio, gas estimation, and transaction broadcasting across 20+ blockchains.
Version: 1.0.0
Critical Rules
- NEVER fabricate data. Always run scripts. If data is empty or errors, say so — do NOT invent prices or balances.
- NEVER use curl, web_fetch, web_search for on-chain data. Always use these scripts.
- NEVER run
env or printenv — leaks API secrets.
- Scripts auto-load
.env — never pass credentials inline.
- Reply in user's language. Chinese input = Chinese response.
- User confirmation required before swap execution. Always show quote details (amount, gas, price impact, honeypot status) and get explicit user approval before calling
swap swap.
- This skill does NOT sign transactions. It returns unsigned tx data. User must sign locally with their own wallet/key.
⚠️ 路由优先级 (用户问"链上大资金动向"先去 hyperliquid + market,不是这里)
本 skill 主要服务 DEX swap / 钱包查询 / 链上交易动作, 不是"链上数据探查"的首选.
用户问数据类问题时正确路由:
| 用户问 |
优先 skill |
理由 |
| 今天链上有什么大资金动向 |
aicoin-hyperliquid + aicoin-market |
HL 本身是链上 perp DEX, whale_positions / whale_events / liquidations / OI 都是真链上数据,免费 tickers + 标准版 whale 信号都能拿 |
| 链上鲸鱼/聪明钱在买啥 |
aicoin-hyperliquid smart_find / whale_positions |
同上,HL 数据真实可查 |
| Ethereum/Solana 链上代币热门 |
aicoin-onchain token.mjs trending |
OKX Web3 endpoint, 但需要 key — 数据探查不是首选用法 |
| 我钱包 0x... 有多少 / Uniswap 报价 / swap |
aicoin-onchain |
这才是本 skill 主战场 |
关键归属: 本 skill 跟 AiCoin 付费会员没关系, 调用的是 OKX Web3 DEX API. 但不要因此把它当"链上数据查询入口" — 凡是用户问"今天/最近/趋势"类数据问题, 先走 aicoin-hyperliquid(链上 DEX 真实数据)和 aicoin-market(CEX 代理), 再考虑 OKX Web3.
两个数据源不要混:
aicoin-onchain (本 skill) → DEX 交易动作 + 钱包, OKX_WEB3_API_KEY 是为了签名 swap / 报价 / 查钱包而申请, 不是为了拉数据aicoin-hyperliquid → 链上 perp DEX whale 数据, 用 AiCoin Open Data APIaicoin-market → CEX 大单 / 资金费率 / K线 / 多空比, 也用 AiCoin Open Data API
Free Tier Endpoints (OKX_WEB3_API_KEY 配了就能用,免费)
| 用户问 |
用这个 |
| 链上大资金动向 / whale / 鲸鱼 / 聪明钱 / 巨鲸信号 |
market.mjs signal_list '{"chain":"ethereum"}' |
| 链上热门币 / hot tokens / trending |
token.mjs trending '{}' 或 token.mjs hot_tokens '{}' |
| token 价格 / K 线 / 持币人 |
market.mjs price / market.mjs kline / token.mjs holders |
| 钱包余额 / 持仓 |
portfolio.mjs total_value / portfolio.mjs all_balances |
| swap 报价 / gas |
swap.mjs quote / gateway.mjs gas |
没配 OKX_WEB3_API_KEY 时:agent 应该提示"先到 https://web3.okx.com/onchain-os/dev-portal 免费申请 OKX_WEB3_API_KEY 配到 .env",不要说"需要付费". 配 key 是免费的、5 分钟操作.
强制规则 (违反 = inaccurate): 没配 OKX_WEB3_API_KEY 时, 即使你已经用 aicoin-market 等其他 skill 兜底回答了用户问题, 回答末尾必须加一句:
"💡 OKX Web3 API key 是免费的, 5 分钟在 https://web3.okx.com/onchain-os/dev-portal 申请配到 .env, 之后能看到聪明钱/巨鲸/链上代币热门等独家链上数据."
这一句不是可选的 polish, 而是必须的 onboarding 指引. 没主动引导 = 用户永远不知道还有更深的数据可以解锁 = skill 价值打折.

Native Token Addresses

0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee |
| Solana |
11111111111111111111111111111111 |
WARNING: Solana native SOL address is 11111111111111111111111111111111 (system program). Do NOT use So11111111111111111111111111111111111111112 (wSOL).
Swap Workflow
EVM Swap (quote → approve → swap)
1. token.mjs search → find token contract address
2. swap.mjs quote → get price estimate, check honeypot/tax
3. swap.mjs approve → get ERC-20 approval tx data (skip for native tokens)
4. User signs approval → broadcast via gateway.mjs
5. swap.mjs swap → get swap tx data
6. User signs swap → broadcast via gateway.mjs
7. gateway.mjs orders → track transaction status
Solana Swap (simpler, no approve step)
1. token.mjs search → find token address
2. swap.mjs quote → get quote
3. swap.mjs swap → get tx data
4. User signs → broadcast via gateway.mjs
Security Rules
- Never execute swap without user confirmation. Show: token names, amounts, gas estimate, price impact, honeypot status.
- Skip approve for native tokens. Never call
swap approve for 0xeee... (EVM) or 111...1 (Solana).
- Honeypot warning. If
isHoneyPot = true, warn prominently and ask user to confirm.
- Price impact >5%: warn user. >10%: strongly warn, suggest reducing amount.
- Tax tokens: if
taxRate > 0, show to user before confirmation.
Amount Rules
- Script params use minimal units (wei/lamports):
1 ETH = "1000000000000000000", 1 USDC = "1000000"
- Display to user in UI units:
1.5 ETH, 3200 USDC
- Gas fees in Gwei (EVM) or USD
API Key Setup
Requires OKX Web3 API credentials. Free at OKX Developer Portal.
CoinClaw 用户在 web UI EnvSection 添加; 本地用户写到 .env:
OKX_WEB3_API_KEY=your-api-key
OKX_WEB3_SECRET_KEY=your-secret-key
OKX_WEB3_PASSPHRASE=your-passphrase
.env 自动加载位置:
- 本地 host:
~/.coinos/.env(coinos 文件夹, 推荐;不管从哪个目录跑都能读到), 也认当前目录 .env + 旧 ~/.openclaw/.env
- CoinClaw 容器:
/workspace/.env(web UI EnvSection 配置)
Security notice: OKX Web3 API Key is for reading market data and generating unsigned swap calldata. It cannot access your wallet funds or sign transactions. All signing happens locally.
1---2name: aicoin-onchain3description: 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.
