# Notice on the Update of STBT Proof of Reserves Data Feed Contract

Dear STBT investors,

Regarding **STBT’s Total Value Of Underlying Assets,** the **reserves feed** will now be maintained through Matrixdock’s **FallbackReserveFeed contract**. The **previous** **Chainlink PoR contract** will be deprecated.&#x20;

This adjustment does not change our principle: **STBT tokens are always fully backed by underlying assets**. By providing daily updates for the proof of reserves, we aim to offer greater clarity and convenience for all users.
