name	aicoin-onchain
description	Use this skill for on-chain DEX operations: token search, swap quotes, DEX trading, wallet portfolio/balance queries, gas estimation, and transaction broadcasting across 20+ blockchains (Ethereum, Solana, Base, BSC, Arbitrum, Polygon, etc.). Use when user says: 'swap ETH for USDC', 'buy token on-chain', 'DEX swap', 'token search on-chain', 'wallet balance', 'portfolio value', 'gas price', 'broadcast transaction', 'trending on-chain tokens', 'hot tokens', 'token holders', 'token liquidity', 'smart money signal', 'whale signal', 'K-line on-chain', '链上交易', '链上swap', 'DEX交易', '买币', '链上行情', '钱包余额', '持仓', 'gas费', '广播交易', '链上热门币', '聪明钱', '巨鲸信号'. Powered by OKX Web3 DEX API with 500+ liquidity sources. MUST run node scripts — NEVER fabricate on-chain data. 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.

Skill Routing

• 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)

Scripts

Action	Params	Description

price_info	address, chain?	Price, market cap, liquidity, 24h change
hot_tokens	chains?, ranking_type?	Hot tokens by trending score
holders	address, chain?	Token holder distribution
liquidity	address, chain?	Top liquidity pools
advanced_info	address, chain?	Risk level, creator, dev stats

market.mjs — Market Data

Action	Params	Description
price	address, chain?	Current token price
prices	tokens, chain?	Batch price query (comma-separated chain:address)
kline	address, chain?, bar?, limit?	K-line / candlestick data
index	address, chain?	Aggregated index price
signal_list	chain, wallet_type?, token_address?	Smart money / whale / KOL signals
signal_chains	(none)	Supported chains for signals

swap.mjs — DEX Swap

Action	Params	Description
quote	from, to, amount, chain, swap_mode?	Get swap quote (read-only)
swap	from, to, amount, chain, wallet, slippage?	Get swap tx data (unsigned)
approve	token, amount, chain	Get ERC-20 approval tx data
chains	(none)	Supported chains for DEX aggregator
liquidity	chain	Available liquidity sources on a chain

portfolio.mjs — Wallet Portfolio

Action	Params	Description
total_value	address, chains	Total portfolio value in USD
all_balances	address, chains	All token balances
token_balances	address, tokens	Specific token balances
chains	(none)	Supported chains for balance queries

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.

Add to .env:

OKX_API_KEY=your-api-key
OKX_SECRET_KEY=your-secret-key
OKX_PASSPHRASE=your-passphrase

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.
