Every successful mainnet decode is added automatically - there's no manual "save" step. The classification filter below starts on Fully + Partly On-Chain; check External there to bring in collections whose metadata and artwork were both found hosted elsewhere (HTTP, IPFS, or Arweave), or Unverified for the rarer cases where there isn't enough evidence to say either way. Bookmarks Only is a browser-local favourites list, separate from this automatic catalogue and not shared with anyone else.

Classifications come from the score and band the Decoder page itself computed live at the moment of decode - the same check that produces that page's own verdict banner - trusted as-is here rather than re-verified independently each time this catalogue loads. Fully on-chain means that decode scored a perfect 10/Excellent. Partly on-chain means it scored Strong or Hybrid, or its metadata was itself identified as coming from an on-chain source. External means its metadata source was HTTP, IPFS, or Arweave and it scored Mostly External or Off-Chain. Unverified covers whatever's left - not enough signal to place it in the other three. Automated findings are not a contract audit or a guarantee about every token ID or future changes.
