If the record is useful, keep it running.
The census, the free checker and the detector are read-only public goods. Nothing here is paywalled and nothing is asked of you. If what is published saves you time, you can send something — it offsets compute, not anyone's pocket.
What it funds
Nothing here is a product pitch
- The census — a longitudinal record of which contracts put upgrade authority on a single key, kept because it cannot be reconstructed later.
- The free checker — runs in your browser, holds no keys, needs no server of ours.
- The detector — MIT, dependency-free, readable in full.
- Compute — the scans run continuously; that is the running cost this offsets.
Addresses
Every chain we can receive on
Listed in rough order of how much survives the trip. Nano is feeless, so everything you send arrives. Monero arrives private. After that, network fees apply and can be larger than a small gift — send what is sensible for the chain.

These are receive-only. There is no key here to leak, and no request for one — if a message ever asks you for a seed phrase or a signature on our behalf, it is not us.
