FDIT, issued by Fidelity Distributors Company LLC, is a tokenized money market fund interest that records onchain ownership of the OnChain share class of the Fidelity Treasury Digital Fund, an SEC-registered Rule 2a-7 money market fund [S1].

Each token represents ownership in the Fidelity Treasury Digital Fund OnChain Class (FYOXX), which holds cash and U.S. Treasury (USD) securities and does not invest in crypto assets [S1]. The fund seeks current income consistent with capital preservation and liquidity, providing yield from its Treasury and cash holdings within a 2a-7 structure [S1]. The fund detail page references an Expenses, Fees and Loads section without rendering numeric values [S1].

The Fidelity Treasury Digital Fund OnChain Class (FYOXX) is a United States money market fund within Fidelity's Money Market Funds line, advised by Fidelity Institutional Asset Management and distributed by Fidelity Distributors Company LLC (FDC LLC), a registered broker-dealer, governed by Rule 2a-7 under the Investment Company Act of 1940 [S1]. A holder owns shares of the fund, with the transfer agent's book-entry record serving as the official ownership record and the blockchain as a secondary record [S1]. Shares are redeemable per standard 2a-7 mechanics, and the fund maintains regulatory daily and weekly liquidity buffers [S1].

FDIT is the onchain token representation of the FYOXX share class, recorded on the Ethereum blockchain [S1]. The transfer agent maintains the official book-entry record and reconciles the secondary blockchain record at least daily, and the blockchain recording does not affect the fund's investments [S1].
