# aicoin-onchain

On-chain trading skill: pulls swap quotes, reads wallet balances and estimates gas. Useful when the agent has to touch a DEX instead of a centralized exchange.

## What it does

The skill covers on-chain actions: token search, swap quotes, gas estimation, wallet portfolio, holder distribution, top liquidity pools. It runs on the OKX Web3 DEX API across Ethereum, Solana, Base, BSC, Arbitrum, Polygon and other chains.

Under the hood are Node scripts — `token.mjs`, `market.mjs`, `swap.mjs`, `portfolio.mjs`, `gateway.mjs`, `trade.mjs` — invoked from the skill directory as `node scripts/swap.mjs quote '{...}'`. Swaps and wallet queries need `OKX_WEB3_API_KEY`, `OKX_WEB3_SECRET_KEY` and `OKX_WEB3_PASSPHRASE` in `.env`. The key is free, and it is a different pair from the one used for CEX trading. Scripts load `.env` themselves, so credentials never go on the command line.

The skill does not sign transactions. It hands back unsigned data and you sign with your own wallet. Before `swap swap` runs, the agent has to show the quote with gas, price impact and honeypot status and wait for your explicit approval. Ask about large on-chain money flows and you get routed elsewhere — those questions belong to `aicoin-hyperliquid` and `aicoin-market`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aicoincom/coinos-skills --skill aicoin-onchain -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/aicoin-onchain/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/aicoin-onchain/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aicoincom/coinos-skills --skill aicoin-onchain -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/aicoin-onchain/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aicoincom/coinos-skills --skill aicoin-onchain -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/aicoin-onchain/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aicoincom/coinos-skills aicoin-onchain
```

2. **Manually: put the files in place**

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aicoincom/coinos-skills --skill aicoin-onchain -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aicoincom/coinos-skills --path skills/aicoin-onchain
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/aicoin-onchain/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aicoincom/coinos-skills --skill aicoin-onchain -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aicoincom/coinos-skills/tree/HEAD/skills/aicoin-onchain/SKILL.md

## When to use it
- compare swap quotes between two tokens before trading
- check token balances held in a wallet
- estimate gas cost on a specific chain
- find a token by name, symbol or contract address
- inspect holder distribution and liquidity pools

## Example prompts
- quote a swap of 1 ETH to USDC on ethereum
- show balances for wallet 0x... on ethereum and solana
- what does gas cost on base right now

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.
