Evidence-reviewed provider snapshot

Evidence reviewed

Regulation / role

Securitize operates through regulated affiliates including an SEC-registered broker-dealer, an SEC-registered transfer agent and an ATS. Reviewed materials distinguish these roles from the legal custodian of underlying fund assets.

Security assurance

No custody-specific key-management assurance was treated as applicable because Securitize is classified here as tokenization/securities infrastructure rather than the legal third-party custodian.

Asset protection

Underlying securities custody depends on the product structure and appointed custodian. For example, Securitize materials for VanEck VBILL name State Street Bank and Trust Company as custodian of fund assets.

Institutional services

Securitize provides end-to-end tokenization and regulated securities infrastructure. In reviewed tokenized-fund examples, underlying asset custody is performed by separate custodians such as State Street.

Procurement caveat: Previous profile language implying that Securitize itself managed custody for BUIDL or offered custody under one regulated perimeter was too broad and has been corrected.
