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