--- title: "What we observe, and what we do not" description: "The derived coverage matrix: every observation class against every chain we know, with the depth we actually reach — and `none` stated rather than left out." canonical: "https://scvd.store/coverage" url: "https://scvd.store/coverage" --- # What we observe, and what we do not The derived coverage matrix: every observation class against every chain we know, with the depth we actually reach — and `none` stated rather than left out. ## What Stated coverage: observation class × chain × depth. Absence is `none`, never implied. Derived from the modules that already know the chain ids — not a brochure. ## Schema scvd-coverage/v1 ## Matrix URL ## Depths - **None** — This class does not operate on this chain. - **Challenge** — We will read a 402 that offers this chain. We do not settle, walk, or read the chain. - **Read** — We read public chain state (a claimed tx, a wallet window, an oracle). - **Till** — We accept payment on this rail. - **Walk** — We pay someone else's door on this rail from the field wallet. ## Chains - eip155:8453 - eip155:84532 - eip155:137 - solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp - eip155:1 - eip155:42161 - eip155:10 - eip155:43114 - eip155:480 ## Sandbox chain eip155:84532 ## Sandbox note Listed so a subject on it is valid.
