name: aicoin-onchain
description: "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 Onchain

On-chain DEX toolkit powered by [OKX Web3 DEX API](https://web3.okx.com). Token discovery, swap execution, wallet portfolio, gas estimation, and transaction broadcasting across 20+ blockchains.

**Version:** 1.0.0

## Critical Rules

1. **NEVER fabricate data.** Always run scripts. If data is empty or errors, say so — do NOT invent prices or balances.
2. **NEVER use curl, web_fetch, web_search** for on-chain data. Always use these scripts.
3. **NEVER run `env` or `printenv`** — leaks API secrets.
4. **Scripts auto-load `.env`** — never pass credentials inline.
5. **Reply in user's language.** Chinese input = Chinese response.
6. **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`.
7. **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 API
- `aicoin-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.

- **CEX trading** (buy/sell on Binance, OKX) → use `aicoin-trading`
- **CEX market data** (funding rates, OI, liquidation maps) → use `aicoin-market`
- **Freqtrade strategies** → use `aicoin-freqtrade`
- **Hyperliquid whales** → use `aicoin-hyperliquid`
- **On-chain DEX operations** → use this skill (`aicoin-onchain`)

**Safety**: Auto-blocks honeypot tokens and trades with >10% price impact.

**EVM only** — Solana auto-trade not yet supported.

## Chain Names

The scripts accept human-readable chain names:

| Chain | Name | Also Accepts |
|-------|------|-------------|
| Ethereum | `ethereum` | `eth` |
| Solana | `solana` | `sol` |
| Base | `base` | |
| BSC | `bsc` | `bnb` |
| Arbitrum | `arbitrum` | `arb` |
| Polygon | `polygon` | `matic` |
| XLayer | `xlayer` | `okb` |
| Avalanche | `avalanche` | `avax` |
| Optimism | `optimism` | `op` |

## Native Token Addresses

| Chain | Address |
|-------|---------|
| EVM (ETH, BSC, Polygon, etc.) | `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

1. **Never execute swap without user confirmation.** Show: token names, amounts, gas estimate, price impact, honeypot status.
2. **Skip approve for native tokens.** Never call `swap approve` for `0xeee...` (EVM) or `111...1` (Solana).
3. **Honeypot warning.** If `isHoneyPot = true`, warn prominently and ask user to confirm.
4. **Price impact >5%**: warn user. **>10%**: strongly warn, suggest reducing amount.
5. **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](https://web3.okx.com/onchain-os/dev-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.
