What does the Longbridge Onchain skill do?

On-chain data analysis framework — covers active addresses, whale behaviour, TVL (total value locked), DEX liquidity, and on-chain valuation metrics: MVRV (market cap / realised value), NVT (network value / transaction volume), SOPR. Longbridge provides spot crypto quotes (.HAS); raw on-chain data requires external sources (Glassnode / Dune Analytics). Triggers: "链上数据", "链上分析", "MVRV", "NVT", "活跃地址", "鲸鱼地址", "TVL", "SOPR", "链上指标", "链上估值", "鏈上數據", "鏈上分析", "活躍地址", "鯨魚地址", "鏈上指標", "鏈上估值", "on-chain data", "on-chain analysis", "MVRV ratio", "NVT ratio", "active addresses", "whale activity", "TVL", "SOPR", "on-chain valuation", "DeFi TVL", "crypto on-chain". It is listed under Data & Analytics on SkillMD.

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> --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).

Output structure

ON-CHAIN ANALYSIS — <TOKEN>  <Date>

PRICE CONTEXT (Longbridge)
Current: $xx,xxx   7d: +x.x%   30d: +x.x%
90d Range: $xx,xxx – $xx,xxx

ON-CHAIN METRICS (from <source>)
MVRV:   x.xx  → [Undervalued | Fair | Overheated]
NVT:    xxx   → [Low | Normal | High]
SOPR:   x.xxx → [Accumulation | Neutral | Distribution]
Active Addresses (7d avg): xxx,xxx

DEFI / TVL (if provided)
Total TVL: $xxB   7d change: +x.x%
Top Protocol: <Name>  $xxB

VERDICT
<2–3 sentence synthesis combining price trend and on-chain signals>
Signal: [Bullish | Neutral | Bearish | Cautious]
