B20 Control Audit
🆕 b20-safety tells you WHICH powers a B20 has; this tells you WHO holds them. Reads the token's role-based access control (mint / burn / seize-via-burnBlocked / pause / admin) from onchain role events and reports the exact controllers, how centralized they are, and whether admin has been renounced. The issuer-control map an agent needs before holding a regulated Base-native asset.
com.tr-$0.05listed
B20 Guard
The live layer over B20 Policy Watch: a network-wide onchain webhook captures every B20 PolicyUpdated/Paused sub-second. Pass a token address for its live guard status, or call with no address for the feed of tokens that JUST attached a sender blocklist (turned seizable) across all of Base.
com.tr-$0.05listed
B20 Policy Watch
The B20-only rug vector: a token can launch clean and later attach a sender blocklist (PolicyUpdated) — silently becoming seizable via burnBlocked. This reads the token's full policy/pause event timeline (CDP-indexed onchain events) plus the live policy state, and tells you if — and exactly WHEN — it turned seizable.
com.tr-$0.03listed
B20 Rebase Tracker
Reads a B20 Asset token's rebase multiplier — the factor that scales every holder's balance. Flags whether balances are being scaled (invisible dilution/inflation the issuer controls). Stablecoin variants return no-rebase.
com.tr-$0.02listed
B20 Token Safety
🆕 Live — B20 is Base's native precompile token standard, and unlike ERC-20 a B20 issuer can freeze holders (Policy Registry) and even SEIZE your balance (burnBlocked) at the protocol level. This reads exactly those powers — seizable, freezable, paused, rebase, uncapped-mint — into one hold/caution/avoid verdict. The first B20-aware safety check on Base.

BFSG Accessibility Quickcheck
Checks a web page for accessibility (a11y) problems from caller-supplied HTML: document language, title, image alt text, form labels, heading order, zoom, landmarks, link text, table headers, iframes, autocomplete. Anchored in the German accessibility act (BFSG), with the WCAG success criteria named per finding as a professional classification, not as a legal claim. States what a pattern parser cannot decide. Not legal advice.
