Fidelity Digital Interest Token
fditWhat is Fidelity Digital Interest Token?
Fidelity Digital Interest Token (FDIT) is an ERC-20-style, compliance-controlled token on Ethereum mainnet. Located sources describe one FDIT as representing one share of the OnChain Class (FYOXX) of Fidelity Treasury Digital Fund, a regulated U.S. government money market mutual fund managed within Fidelity’s fund complex. FDIT is the on-chain representation of a fund interest, not a direct claim to a particular Treasury bill, Fidelity corporate equity, or an independently guaranteed digital dollar.
What problem does Fidelity Digital Interest Token solve?
FDIT brings the record and transfer layer for a traditional money market fund share onto a public blockchain. This can make a regulated cash-management instrument easier to integrate with eligible on-chain financial infrastructure while retaining the fund’s conventional portfolio, shareholder, compliance, expense, and risk framework. It does not eliminate investor-eligibility rules, transfer controls, fund expenses, or the possibility that the fund could fail to maintain a $1.00 share value.
How does Fidelity Digital Interest Token work?
Eligible subscriptions create fund shares represented by FDIT on Ethereum, and redemptions can be reflected through token burns. The fund pools investor assets, invests primarily in cash and short-dated U.S. Treasury securities, and distributes investment income under its governing documents. The verified Ethereum deployment is an upgradeable proxy whose published implementation exposes role-controlled minting, burning, pausing, updating, role-management, and transfer-compliance functions; Etherscan also shows labeled freeze and unfreeze transactions. The current controllers, role assignments, multisig or timelock arrangements, investor-eligibility requirements, and operational redemption path were not established by the reviewed pages and should be checked against Fidelity’s current prospectus, onboarding terms, and live contract state.
Key facts
- FDIT represents a share of Fidelity Treasury Digital Fund’s OnChain Class; FYOXX is the conventional mutual-fund share-class ticker, while FDIT is the blockchain token symbol.
- The identified Ethereum mainnet token contract is 0x48aB4e39AC59F4E88974804B04A991b3a402717f and uses 18 decimals.
- Fidelity’s August 2026 fact sheet lists December 23, 2024 as the fund inception date and August 4, 2025 as the OnChain Class inception date.
- The fund normally invests at least 99.5% of total assets in cash and U.S. Treasury securities and at least 80% in U.S. Treasury securities. Fidelity says it intends to use cash and Treasury securities with 93 days or less remaining or original maturity.
- The fund seeks a stable $1.00 net asset value, but Fidelity warns that investors can lose money and that the fund is neither FDIC-insured nor otherwise government-guaranteed.
- The August 2026 fact sheet reports a 0.25% gross prospectus expense ratio and a 0.20% net prospectus expense ratio, with the contractual expense cap then scheduled through August 31, 2027. These figures can change and require confirmation in the latest prospectus.
- The verified deployment is upgradeable and compliance-controlled, not permissionless. Its published implementation includes mint, burn, pause, update, role-management, and transfer-related functions, and the transaction history includes freeze and unfreeze calls.
- No fixed maximum token supply was established by the located fund materials. Supply can change as fund shares are issued or redeemed, and displayed supply is time-sensitive rather than a permanent cap.
- RWA.xyz records the represented share under CUSIP 31617H813 and ISIN US31617H8135; holders have a fund interest rather than direct title to individually identified Treasury securities.
- Ondo Finance’s dated September 9, 2025 launch account describes Ondo as the initial anchor investor through OUSG and says OUSG then represented more than 99% of FDIT assets. This is a historical launch-era concentration figure, not a statement of the current asset mix.

Frequently asked questions
Is FDIT a stablecoin?
Not in the usual payment-token sense. FDIT represents a share of a government money market mutual fund that seeks to maintain a $1.00 NAV and earn portfolio income. Fidelity states that the fund can lose value and is not insured or guaranteed by the FDIC or another government agency.
What assets support FDIT?
The represented fund normally invests at least 99.5% of total assets in cash and U.S. Treasury securities, with a disclosed emphasis on very short maturities. A holder owns a fund interest under the governing documents, not direct title to specific Treasury bills.
Where is FDIT issued?
The located deployment is on Ethereum mainnet at 0x48aB4e39AC59F4E88974804B04A991b3a402717f. Etherscan identifies it as Fidelity Digital Interest Token, reports 18 decimals, and links it to Fidelity’s fund information.
Can anyone transfer or redeem FDIT freely?
The contract has role-based compliance and administrative controls, including freeze-related functionality. The reviewed public pages do not fully establish current eligibility, whitelisting, transfer, subscription, or redemption requirements, so these conditions must be verified through Fidelity’s current offering documents and onboarding process.
What rights and returns does FDIT provide?
Located sources describe FDIT as representing a share of the OnChain Class. The intended economic return comes from the underlying money market fund’s income, net of expenses, and varies with the portfolio and interest-rate environment. No Fidelity equity, protocol-governance right, direct ownership of specified Treasury securities, or unconditional one-dollar redemption right was established.
