longbridge-onchain

On-chain data analysis framework — MVRV, NVT, SOPR, whale behaviour, TVL, and DEX liquidity.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

Trigger on prompts asking for:

• On-chain valuation — "MVRV 是多少", "BTC MVRV ratio", "NVT 指标"
• Whale or address activity — "鲸鱼地址动向", "whale activity", "active addresses"
• DeFi / TVL — "以太坊 TVL", "DeFi TVL", "链上流动性"
• On-chain sentiment — "SOPR", "链上持仓盈亏", "on-chain profit/loss"

Data scope: Longbridge CLI provides spot crypto price and price history only. On-chain raw data (address activity, TVL, whale transfers) is not available via the Longbridge CLI — the user must supply external data (Glassnode, Dune Analytics, Nansen, etc.) or paste it directly. This skill interprets and synthesises that data.

Workflow

1. Fetch crypto spot quote and recent price history from Longbridge.
2. Ask the user to provide on-chain data, or guide them to a public source:
3. Glassnode: MVRV, NVT, SOPR, active addresses
4. Dune Analytics: DEX volume, TVL by protocol
5. Nansen: whale wallet labels and flows
6. DefiLlama: cross-chain TVL
7. Interpret the metrics using standard thresholds:
8. MVRV > 3.0 → historically overheated; < 1.0 → historically undervalued
9. NVT > 90th percentile → overvalued relative to transaction throughput
10. SOPR > 1 → holders selling at profit (potential distribution)
11. SOPR < 1 → holders selling at loss (potential capitulation)
12. Synthesise a verdict: Undervalued / Fair Value / Overheated / Distribution Zone.
13. Cross-reference with price trend from Longbridge kline data.

If unsure of exact flag names, run longbridge <subcommand> --help before proceeding.

CLI

# Crypto spot quote
longbridge quote BTCUSD.HAS --format json

# Recent daily price trend (ETH example); run --help for period/count flags
longbridge kline ETHUSD.HAS --format json   # run --help for available flags

Supported crypto symbols use the .HAS suffix (e.g. BTCUSD.HAS, ETHUSD.HAS, SOLUSD.HAS).

MCP fallback

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime.
