Enterprise capital fund a16z crypto has introduced that Professor Craig Lewis, a Vanderbilt professor and former SEC Chief Economist, has submitted an financial evaluation to the SEC concerning the enterprise capital agency’s proposal for a protected harbor for software program. 

Lewis, who beforehand served because the Director of the SEC’s Division of Financial and Danger Evaluation, argues that tokenized securities on decentralized finance (DeFi) platforms can cut back prices, allow 24/7 markets, and improve transparency, regardless of sure regulatory challenges.

The evaluation, commissioned by a16z and carried out by Professor Lewis, examines the financial prices and advantages of tokenized securities. The evaluation provides insights into how blockchain know-how might doubtlessly overhaul conventional monetary programs. Although a16z funded the work, Lewis utilized an impartial and rigorous methodology in assessing the proposal’s deserves.

In his findings, Lewis identifies 5 key advantages the protected harbor might allow. First, atomic settlement can remove counterparty credit score dangers tied to delayed settlement home windows, in addition to mitigate the systemic dangers related to central counterparty failures. Second, on-chain transparency might exchange opaque proprietary ledgers with publicly verifiable data of all transactions. Third, steady 24/7 buying and selling would enable for expanded worth discovery and liquidity, unrestricted by conventional trade hours. Fourth, sensible contracts might result in direct price reductions by automating company actions equivalent to dividend funds and compliance capabilities. Fifth, tokenization might decrease entry boundaries, fostering innovation by enabling new builders to problem established monetary establishments.

Nevertheless, Lewis additionally highlights 4 potential prices. One concern is that investor protections might erode, particularly since qualifying purposes wouldn’t have the capability to freeze belongings or reverse transactions, as broker-dealers at present can. One other threat recognized is regulatory arbitrage, the place conventional broker-dealers would possibly restructure to keep away from sure regulatory obligations, though Lewis argues that the operational hurdles would doubtless forestall this. Moreover, increasing tokenized securities buying and selling would possibly fragment the market, doubtlessly introducing dangers to conventional programs, particularly if leverage in DeFi protocols spreads stress to broader markets.

Lastly, Lewis notes potential buying and selling prices for retail buyers, equivalent to variable gasoline charges and slippage, although he factors out that these prices should be weighed in opposition to current charges in conventional finance, that are additionally appreciable. Moreover, he mentions that DeFi charges are quickly reducing, as seen with Ethereum’s Dencun improve, which decreased Layer 2 posting charges by over 90%.

Lewis additional explains that the evaluation is particularly targeted on front-end purposes that meet the protected harbor proposal’s standards. These purposes are passive software program interfaces that, by design, don’t create the dangers that the SEC’s Trade Act seeks to handle. The standards for eligibility embody non-custodial structure, no discretionary commerce execution, no solicitation of funding, and unique integration with decentralized protocols.

Evaluating these blockchain apps to conventional broker-dealer programs, Lewis argues that the latter carry quite a few hidden prices, equivalent to clearing and settlement expenses, middleman markups, and insurance coverage buffers, which contribute to the inefficiency of current monetary infrastructure.

Lewis concludes {that a} formal SEC financial evaluation of those prices and advantages would doubtless affirm that the protected harbor proposal would enable for the conclusion of serious financial advantages tied to tokenized securities.
