How this service works
Is this chain alive: TVL trend over 1y/6m/90d/30d
Output
Returns a JSON object with a boolean 'ok' field, a 'verdict' string summarizing chain health, an array of 'flags' (each with a 'code' and 'msg') indicating issues like COLLAPSED, STILL_FALLING, or TINY TVL, and a 'disclaimer'. An empty flags array means no checks failed.
Example use cases
Pre-deployment chain viability check
“Before I deploy any liquidity on the Fantom chain, can you check whether it's still alive and growing, or if the TVL has collapsed over the past year?”
Abandoned chain detection for portfolio review
“I hold assets on the Celo chain — is it still active? Check the TVL trend across 1 year, 6 months, 90 days, and 30 days and flag anything concerning.”
Chain due diligence for DeFi protocol launch
“We're considering launching a protocol on Moonbeam — can you verify if the chain ecosystem is still healthy or if TVL has been falling significantly?”
Technical details
Endpoint
POSThttps://poolproof.qalibr.ru:7443/v1/chainWhen to prefer
Use this endpoint when you need a quick, opinionated verdict on whether a blockchain is still alive or has been effectively abandoned, based on multi-window TVL trend analysis rather than a single snapshot price or raw TVL number. Prefer this over generic TVL APIs when you specifically need abandonment/collapse detection with structured flags for automated decision-making in DeFi agent workflows.
Side effects
- Unknown or unsupported chain identifier returns an error or empty result
- Chain data unavailable due to missing historical TVL data
- Payment not completed results in 402 response
- Malformed request body returns validation error
- Chain is so new that insufficient historical windows exist to evaluate trends
