Frax Community,
Given recent conversations surrounding treasury management preempting the upcoming launch of FXBs in 2024, we wanted to formally introduce ourselves as Adapt3r Digital, the General Partner of tfBILL, our on-chain treasury bill product. We are proposing an initial maximum allocation limit of $20 million to tfBILL, in line with Centrifuge’s recent proposal.
tfBILL is a purpose-built, scalable, already live solution that allows direct access to U.S. Treasury Bill yields so that protocols can leverage all of the benefits of RWAs. Users deposit USDC into a smart contract vault, obtaining tfBILL tokens representing Limited Partner interest in a BVI-registered fund holding exclusively treasury bills. The entity, designed for bankruptcy remoteness, assures investment security with full legal recourse for tfBILL holders. Launched in September 2023, the vault currently accepts USDC deposits from KYC'd non-U.S. investors, with a Total Value Locked (TVL) of ~$8,600,00 and an estimated yield of 5.32%. We can adopt any structure that aligns with FRAX requirements/goals and have the flexibility to provide both onshore and offshore US operations. If FRAX decides to operate in the US through FinresPBC, we have the capacity to participate. Importantly, we are fully compliant and have a clean cohort of investors in our fund. No anonymous users today. tfBILL differentiates itself through compliance-focused strategies, emphasis on regulated counterparties, enhanced transparency via on-chain Net Asset Value attestations, and on-demand liquidity. Utilizing battle-tested smart contracts from TrueFi ensures robust security and operational independence. tfBILL redefines simplicity, transparency, and security in on-chain treasury instruments.
Our flagship product, the Adapt3r Short-Term U.S. Treasury Bill Fund, offers on-chain stablecoin holders 24/7, direct access to US Treasury Bill yield. Upon depositing USDC to the smart contract vault, investors are issued tfBILL tokens which represent Limited Partner interest in a BVI registered professional fund that exclusively holds treasury bills. The entity is bankruptcy remote and solely owned by the holders of tfBILL, who have full legal recourse to tfBILL’s underlying securities. The vault is built on TrueFi’s open, transparent, and battle-tested smart contracts and is conveniently offered on Archblock’s institutional-grade frontend marketplace.
The vault was deployed in September 2023 and currently accepts USDC deposits from KYC’d non-US investors. At the time of writing, the TVL of the vault is approximately $8,600,000 and offers an estimated yield of over 5%.
tfBILL was built in response to compliance and complexity concerns we continually heard from DAOs and on-chain investors about existing treasury bill offerings. Specifically, many DeFi entities and users expressed difficulty evaluating existing options due to contrived and opaque legal structures with uncertain investor recourse, hidden layers of fees, and aggressive operation in regulatory “grey areas.”
Since the beginning, the primary goal has been to build an on-chain treasury instrument that is simple, transparent, and secure for all users. Here are some of the key ways tfBILL differentiates itself:

Ultimately, Adapt3r Digital and our affiliate, MJL Capital, are deeply aligned with the Frax mission and purpose. We want to see the project succeed. If you are looking to learn more about tfBILL check out our documentation or reach out via DM or email.
The pricing for this proposal is structured to streamline fees. The potential usage of FXS as also helps to align incentives towards long-term interests versus short-term benefits. The fee structure is as follows:
| Portfolio Fee | 0.30% p.a. on assets in tfBILL up to $50M, 0.2% $50-100M, 0.1% >$100M | 0.30% is paid on an ongoing basis to Adapt3r, payable in stablecoins and/or FXS tokens. The difference between 0.30% and the effective fee is rebated from Adapt3r back to Frax on an ongoing basis. |
|---|---|---|
| Protocol Fee | 0.20% | This fee is currently on holiday and not applicable to Frax’s potential investment. |
For: Support for onboarding the Frax protocol to Adapt3r Digital with mentioned fees and an initial maximum allocation limit of $20 million to tfBILL.
Against: Do nothing.
