What It Does

Pulls the full DefiLlama protocol list and flags protocols with abnormal 24h TVL movement. Anomalies are classified by type and severity so you can triage at a glance.

Anomaly Types

Type	Severity	Description
`rug_or_drain`	Critical	TVL collapsed to near-zero from significant prior value
`severe_drain`	High	−70%+ TVL change in 24h (likely hack, exploit, or mass exit)
`major_drain`	Medium	−40%+ TVL change (significant capital flight)
`suspicious_spike`	Medium	+500%+ TVL spike (likely TVL manipulation or bootstrapped farming)
`major_inflow`	Info	+100%+ TVL growth (new incentive program, major partnership)

Input

Field	Type	Default	Description
`minTvlMillion`	number	`0.1`	Min protocol TVL in $M to include. Filters dust/micro-protocols.
`minChangeAbsPct`	number	`40`	Min absolute 24h change % to report.
`severityFilter`	string	`""`	Filter to one severity: `critical`, `high`, `medium`, `info`
`sortBy`	string	`"severity"`	Sort: `severity`, `change_1d`, or `tvl`
`limit`	integer	`100`	Max results (up to 500)

Key Value Store

A SUMMARY object is saved with:

total_anomalies: count of anomalies found
by_severity: counts per severity level
by_type: counts per anomaly type
critical_alerts: top 10 critical findings
high_alerts: top 10 high-severity findings

Pricing

$0.005 per run — flat rate. No API key required.

Use Cases

Security monitoring: schedule every hour to catch exploits early
Risk management: check exposure before entering large DeFi positions
Research signals: large inflows often precede token price movements
Portfolio protection: alert when protocols you use have anomalous TVL drops

Data Source

DefiLlama free API (api.llama.fi/protocols) — public, no auth required.

Notes

TVL data is delayed ~1 hour from real-time blockchain state
A "suspicious spike" is not necessarily malicious — it can be genuine growth from new farms
rug_or_drain detection uses 7d TVL to estimate prior value; may fire on newly listed protocols
For hacks specifically, cross-reference with Rekt.news or DeFiYield Shield
