OpenClaw 评估

The skill's stated purpose (a crypto CLI) matches the commands and behavior in SKILL.md, but the registry metadata omits the multiple sensitive environment variables the skill actually requires and there are inconsistencies in env-var names and provenance — this mismatch and the unknown source warrant caution.

# Onchain CLI

CLI for crypto portfolio tracking, market data, and CEX history.

## First-Time Setup (Required)

Before using most features, users must configure their API keys:

```bash
onchain setup
```

This interactive wizard helps configure:
- **Coinbase/Binance** - For CEX balances and trade history
- **DeBank** - For EVM wallet data (Ethereum, Polygon, Arbitrum, etc.)
- **Helius** - For Solana wallet data

**Without setup**: Only `onchain price` and `onchain markets` work (using free CoinGecko tier).

**Verify setup**: Run `onchain test` to check which providers are configured and working.

**Agent note**: If a command fails with "not configured" or "API key required", guide the user to run `onchain setup` first, then `onchain test` to verify.

## Invocation

```
onchain <command>
```

## Commands

### Market Data

```bash
onchain price <token>         # Token price (btc, eth, sol, etc.)
onchain markets               # Market overview with trending
onchain search <query>        # Search tokens by name or symbol
onchain gas                   # Current gas prices (Ethereum default)
onchain gas --chain polygon   # Gas prices for other EVM chains
```

### Wallet Data

```bash
onchain balance [address]           # Token balances (auto-detects EVM/Solana)
onchain balance --chain polygon     # Filter by chain
onchain history [address]           # Transaction history
onchain portfolio [address]         # Full portfolio with DeFi positions
```

### Transaction Lookup

```bash
onchain tx <hash>                   # Lookup transaction details (auto-detects chain)
onchain tx <hash> --chain base      # Specify chain explicitly
onchain tx <explorer-url>           # Paste block explorer URL directly
```

Supports EVM chains (Ethereum, Polygon, Base, Arbitrum, Optimism, BSC, Avalanche, Fantom) and Solana. Accepts raw hashes or explorer URLs (etherscan.io, basescan.org, solscan.io, etc.).

#### Example Output
```

```

**This output contains all available transaction data.** The CLI queries Etherscan/Solscan APIs directly - there is no additional data available from other sources.

### CEX Data

```bash
onchain coinbase balance      # Coinbase balances
onchain coinbase history      # Coinbase trade history
onchain binance balance       # Binance balances
onchain binance history       # Binance trade history
```

### Prediction Markets

```bash
onchain polymarket tags              # List all available tags/categories
onchain polymarket tags --popular    # Show popular tags by market count
onchain polymarket trending          # Trending markets (respects config filters)
onchain polymarket trending --all    # Show all markets (ignore config filters)
onchain polymarket trending --exclude sports,nfl   # Exclude specific tags
onchain polymarket trending --include crypto,ai    # Only show specific tags
onchain polymarket search <query>    # Search markets (respects config filters)
onchain polymarket view <slug>       # View market details
onchain polymarket sentiment <topic> # Analyze market sentiment for a topic
```

**Sentiment analysis**: Analyzes prediction markets to determine bullish/bearish expectations:
```bash
onchain polymarket sentiment fed        # Fed rate expectations
onchain polymarket sentiment bitcoin    # Bitcoin market sentiment
onchain polymarket sentiment ai         # AI-related predictions
onchain polymarket sentiment trump      # Political sentiment
onchain polymarket sentiment fed --json # JSON output for agents
```

**Tag filtering**: Configure default excludes in `~/.config/onchain/config.json5`:
```json5
{
  "polymarket": {
    "excludeTags": ["sports", "nfl", "nba", "mlb"],
    "includeTags": []  // empty = all non-excluded
  }
}
```

### Configuration

```bash
onchain setup                 # Interactive setup wizard
onchain config                # View current config
onchain config wallet add <name> <address>
onchain config wallet set-default <name>
```

## Global Options

- `--json` - Output as JSON (agent-friendly)
- `--plain` - Disable colors and emoji
- `--timeout <ms>` - Request timeout

## Configuration

Config file: `~/.config/onchain/config.json5`

onchain polymarket trending --all            # All markets, ignore config
onchain polymarket trending --exclude sports # Filter out sports on-the-fly
```

### Lookup a transaction
```bash
onchain tx 0xd757e7e4cdb424e22319cbf63bbcfcd4b26c93ebef31d1458ab7d5e986375f31
onchain tx https://basescan.org/tx/0x...  # Or paste explorer URL
```

### Search for tokens
```bash
onchain search pepe               # Find tokens matching "pepe"
onchain search "shiba inu" -l 5   # Limit to 5 results
```

### Check gas prices
```bash
onchain gas                   # Ethereum gas prices
onchain gas --chain polygon   # Polygon gas prices
onchain gas --json            # JSON output
```

### JSON output for scripts

onchain --json price eth | jq '.priceUsd'
```

## Supported Chains

### EVM (via DeBank)
Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Base, zkSync Era, Linea, Scroll, Blast, Mantle, Gnosis, Fantom, Celo, and more.

### Solana (via Helius)
Full Solana mainnet support including SPL tokens and NFTs.

## Agent Integration

This CLI is designed for agent use. Key patterns:

1. **Always use `--json`** for programmatic access
2. **Check exit codes** - 0 for success, 1 for error
3. **Use saved wallets** - Configure once with `onchain setup`, reference by name
4. **Rate limiting** - APIs have rate limits, add delays between rapid calls

### Example Agent Usage

```bash
# Get portfolio value
VALUE=$(onchain --json portfolio main | jq -r '.totalValueUsd')

# Get price with change
onchain --json price btc | jq '{price: .priceUsd, change24h: .priceChange24h}'

# Check if market is bullish
CHANGE=$(onchain --json markets | jq '.marketCapChange24h')

# Get transaction details as JSON
TX=$(onchain --json tx 0x... --chain base)
echo $TX | jq '{status: .status, from: .from, to: .to, method: .methodId}'
```

### Transaction Lookup Guidance

**IMPORTANT: Trust the CLI output.** The `onchain tx` command queries Etherscan (EVM) or Solscan (Solana) APIs directly and returns all available data.

**DO NOT:**
- Use curl to hit Etherscan/Basescan APIs directly
- Use `cast` or other CLI tools as "fallbacks"
- Use WebFetch to scrape block explorer websites
- Assume the CLI is missing data - it returns everything available

**DO:**
- Use `onchain tx <hash>` or `onchain tx <explorer-url>`
- Use `--json` for structured data parsing
- Interpret the output directly to answer user questions

**Example interpretation:**
```bash
onchain tx 0x... --chain base
```
If output shows `Status: SUCCESS`, `From: 0x...`, `To: 0x...`, `Method ID: 0x6a761202` - that's a successful contract interaction. The method ID `0x6a761202` is `execTransaction` (Gnosis Safe). No additional lookups needed.
