aicoin-onchain

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. 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.

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.

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.
