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.
