BaseTBILL tokens represent shares in a BVI professional fund holding short-dated US Treasury bills, minted and redeemed through an ERC-4626 smart contract vault. OpenEden was the first tokenized treasury issuer to receive an investment-grade rating from Moody's, and publishes daily reserve and NAV reports.
Moody's-rated tokenized T-bill vault with ERC-4626 composability.
Prism analyst note
TBILL pioneered the ERC-4626 vault interface for treasuries, making it the most DeFi-composable of the rated products. The Moody's rating and Chainlink proof-of-reserve integration give it above-average transparency for its size. Scale is the main limitation: liquidity and depth trail the megafunds, so it suits mid-size allocations rather than institutional block flows.
