IL Observer
IL Observer is a read-only on-chain LP impermanent-loss tracker.
Paste a wallet address and we replay every open LP position
on-chain, then compare current value against a HODL benchmark.
Fees and rewards are reported separately from IL. The core
scan/share API is free and public; x402 may be used for paid
deep JSON exports.
This page is JavaScript-driven. If you can't run JS, the
following links go straight to verified demo positions rendered
as static HTML, and the public API at
/api/openapi.json works without
a browser.
