The mint is Token-2022. Compliance is a layer on top. Stack: Token ACL (sRFC 37) and the Solana Attestation Service. Accounts are born frozen. Gate decides thaw. npm @metaplex-foundation/mpl-permission. Live on mainnet in early access. Docs: not audited. Do not custody real assets without coordinating with Metaplex.

SECZ went live on the NYSE and on Solana on the same day. On Solana every Securitize asset is a Token-2022 mint that enforces its own compliance — but the tokenized stock uses defaultAccountState + pausable + scaled UI amount, while the funds use a transfer hook.
