B20 Token Safety$0.04 / call402.com.tr
B20Base-token-standardFreezeSeizeToken-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, and says whether they are the compliance surface a tokenized stock must carry or a token merely wearing an equity ticker. The first B20-aware safety check on Base.
