SEC effectiveness opened Arca’s Ethereum-based Treasury fund

The U.S. Securities and Exchange Commission made Arca U.S. Treasury Fund’s Form N-2 registration effective at 9:00 a.m. Eastern on July 6, 2020, clearing the fund to begin a continuous offering of shares represented as ArCoin tokens on Ethereum. Arca announced the offering that morning, while the definitive prospectus dated July 6 described a registered closed-end fund joining a conventional Treasury portfolio to blockchain-based share transfer.

The distinction matters. ArCoin was not a cryptocurrency exposure product, and effectiveness did not amount to an SEC endorsement of the investment. The prospectus said the fund would not invest directly or indirectly in digital assets. Instead, under normal circumstances, at least 80% of assets would be invested in U.S. Treasury bills, notes and bonds. The blockchain component concerned how the fund’s shares could be represented and transferred.

A regulated share with a blockchain rail

The offering set an initial net asset value of $1 per share and a $1,000 minimum initial investment, with later purchases permitted from $100. The fund sought maximum total return consistent with preserving capital. ArCoins used the ERC-1404 standard, an extension of Ethereum’s ERC-20 design that allowed compliance-related transfer restrictions to be enforced in the smart contract.

That design made the product a hybrid rather than a permissionless token. A prospective holder had to complete anti-money-laundering and know-your-customer checks and be whitelisted by DTAC, the transfer agent, before buying directly or receiving shares peer to peer. Ethereum would provide a publicly viewable transaction record, but DTAC’s books remained the official record of legal and beneficial ownership. The prospectus required the transfer agent to reconcile Ethereum transactions with those records at least daily.

This split was central to the experiment. Investors could initiate transfers between approved wallets without a central clearing agency, yet the regulated administrator retained the power to freeze, revoke and reassign tokens when necessary. ArCoin therefore tested whether a public blockchain could serve as a transaction and audit layer inside the controls of a registered investment company, not whether fund ownership could exist outside securities law.

What the launch did—and did not—prove

Arca called the vehicle the first fund registered under the Investment Company Act of 1940 to issue shares as digital securities. CoinDesk’s July 6 report similarly described it as apparently the first regulated fund represented by digital shares after nearly 20 months of regulatory work. The SEC’s notice verifies the registration’s effectiveness and the dated prospectus verifies the structure; neither record independently certifies every promotional “first” asserted by the sponsor.

The launch also did not establish a liquid market. The prospectus said ArCoins were not listed on a national securities exchange or another exchange. Peer-to-peer prices could be negotiated away from the fund’s daily NAV, and only whitelisted counterparties could transact. The filing warned that low or nonexistent transaction volume could mean limited or no liquidity and that an exchange market might never develop.

Those constraints explain why July 6, 2020 was institutionally significant without implying immediate scale. The offering put Ethereum-based transfer mechanics inside a familiar federal fund framework, backed primarily by Treasurys and administered through identified service providers. It offered a concrete test of tokenized securities infrastructure while leaving adoption, secondary-market liquidity and operational reliability unresolved.

Record limits

The contemporaneous records establish effectiveness, offering terms and announced availability on July 6, 2020. They do not establish the value of subscriptions accepted that day, the number of outside investors, or meaningful peer-to-peer trading volume. No market-price performance claim is warranted from the launch-day evidence.
