What is Token-2022 (SPL)?

Token-2022 is Solana's programmable token standard: everything the classic SPL token does, plus an extension system that lets an issuer configure transfer hooks, transfer fees, freeze and mint authorities, confidential transfers, and metadata directly on the token itself.

For regulated assets that is the unlock: compliance powers (who may hold, when transfers pause) live on-chain in the token program rather than bolted on by each venue. The same machinery that makes a token compliant also makes its powers visible: the extensions are public data, and U.CASH lists them on every Token-2022 asset page.

Token-2022 (SPL) on U.CASH

Every Solana asset on U.CASH, from the xStocks to the pegged stablecoins, is a Token-2022 token; each asset page shows its program, decimals, authorities, and the exact extension set the issuer configured.

Token-2022 (SPL): FAQ

Why do issuers want freeze powers on a token?
Regulated issuers must be able to freeze or pause for compliance (sanctions, court order, error). On Token-2022 that power is a disclosed on-chain configuration, not a surprise.
What is a transfer hook?
A program the token calls on every transfer, letting the issuer enforce rules (eligibility, limits) at the protocol level. Transfers that fail the hook revert on-chain.
