Matrixdock Short-term Treasury Bill Token (STBT)Updated 7 Nov 2026

A tokenised Treasury bill product from Matrixport's Matrixdock, launched in early 2023 and pitched as one of the first in Asia. It gives eligible stablecoin holders exposure to Treasuries maturing within six months and repo backed by them, with a one-dollar token and Chainlink proof of reserve on Ethereum. It has shrunk to a small size.
