Editor's Note: When regulators begin actively promoting "traditional securities going on-chain," the question is no longer whether the technology is feasible, but whether the system is ready to keep up.
This article revolves around a key proposal: Against the backdrop of the U.S. Securities and Exchange Commission (SEC) advancing the on-chaining of financial markets, a16z and the DeFi Education Fund proposed a "Software Safe Harbor" framework, attempting to delineate regulatory boundaries for a new class of market participants—non-custodial, disintermediated blockchain applications.
The core logic is not complicated: If these applications are merely neutral software interfaces, do not control assets, do not execute trades, and do not provide advice, should they still be included in the regulatory framework of the traditional brokerage system?
An analysis by former SEC Chief Economist Craig Lewis provides a more structured answer to this question. Instead of starting from "whether to regulate," he returns to a more fundamental comparison: Given the existing brokerage system's inherent high costs and lack of transparency, does introducing on-chain trading and automated settlement weaken the market or restructure its operation?
On one hand, atomic settlement, on-chain transparency, and 7×24 trading are redefining the efficiency boundaries of financial infrastructure; on the other hand, investor protection mechanisms, market fragmentation, and new types of risks are also emerging simultaneously. The real divergence lies not in whether these risks exist, but in whether they already exist in the traditional system in another form, having long been overlooked.
From this perspective, the "Safe Harbor Proposal" is more like an institutional experiment: It attempts to open a limited but verifiable space for on-chain finance without completely overturning the existing regulatory framework. The key question then shifts from "whether to go on-chain" to "which parts can go on-chain first."
If the past decade of the crypto industry has been about approaching traditional finance technologically, then the next real variable may come from how regulation redefines the role boundaries of "intermediaries."
The following is the original text:
Bringing traditional securities on-chain is a core priority for the current U.S. Securities and Exchange Commission (SEC). Recognizing the potential of tokenization, under the leadership of Chairman Atkins, the Commission launched "Project Crypto" 9 months ago, aiming to update U.S. securities-related rules and regulatory systems. Its goal is to promote the gradual migration of the national financial markets on-chain, thereby achieving advantages such as instant settlement, 7×24 hour trading, and cost reduction.
But to truly unlock the full potential of tokenized securities, innovators and investors still need clear "rules of the game," especially for those blockchain applications that allow users to trade tokenized securities peer-to-peer without intermediaries.
Based on this, we, together with the DeFi Education Fund, submitted a "Software Safe Harbor" proposal to the SEC last August, clearly defining under what conditions such blockchain-based applications—i.e., programs that serve as neutral software enabling users to interact with public blockchain networks and smart contract protocols—can be exempt from the registration requirements of the Securities Exchange Act of 1934. This proposal not only explains how these applications create value for market participants but also how they align with the SEC's core mission in protecting investors, maintaining fair and orderly markets, and facilitating capital formation.
Today, Vanderbilt University professor and former SEC Chief Economist and Director of the Division of Economic and Risk Analysis, Craig Lewis, has formally submitted his economic analysis report on this "Software Safe Harbor" proposal to the SEC. While Lewis's research focuses on the proposal itself, it more broadly assesses the economic costs and benefits of tokenized securities, providing important insights into how blockchain technology can reshape the traditional financial system. Although this study received funding support from a16z, Professor Lewis employed an independent and rigorous methodology in his evaluation.
In his analysis, Lewis identifies five potential benefits that this safe harbor mechanism could unlock for compliant applications:
· Atomic Settlement: Eliminates counterparty credit risk from delayed settlement and reduces systemic risk that could arise from central counterparty failure.
· On-Chain Transparency: Replaces opaque private ledger systems with publicly verifiable transaction records.
· 7×24 Continuous Trading: Breaks through the time and geographical limitations of traditional exchanges, improving price discovery efficiency and liquidity.
· Substantial Cost Reduction: Automates dividend distribution, compliance processes, etc., through smart contracts. For example, research by Ripple and BCG shows that tokenizing investment-grade bonds can reduce operational costs by 40% to 60%.
· Lower Barriers to Entry: Attracts new developers into the market, creating competitive pressure on traditional financial institutions, driving their innovation, ultimately benefiting users.
At the same time, Lewis also points out four types of potential costs that this proposal might bring:
· Weakened Investor Protection: For instance, traditional brokers can freeze assets or reverse transactions, whereas compliant applications are not designed to have this capability.
· Regulatory Arbitrage Risk: Some traditional institutions might attempt to transform into compliant applications to evade regulatory obligations, but their transformation costs could be high.
· Market Fragmentation Risk: Trading of tokenized securities could further fragment market liquidity and transmit risks to the traditional financial system through DeFi leverage mechanisms. However, Lewis believes this should be assessed in comparison to the currently existing dark pools and over-the-counter trading systems.
· Retail Trading Cost Issues: Such as Gas fee volatility, slippage, and smart contract vulnerabilities, but these should be viewed in contrast to the hidden costs in traditional finance. Meanwhile, DeFi fees are dropping significantly; for example, Ethereum's Dencun upgrade has reduced L2 data costs by over 90%.
Lewis's analysis is specifically limited to front-end applications that meet the safe harbor conditions and emphasizes that these applications are essentially "passive software interfaces" whose design does not introduce the risks the Securities Exchange Act seeks to avoid. These conditions include:
· Non-custodial architecture
· No autonomous trade execution authority
· No marketing or investment advice
· Only connecting to truly decentralized (or actively moving towards decentralization) protocols
He further points out that the benchmark for comparison should not be some idealized market structure, but rather the current brokerage system—which contains numerous hidden costs, such as DTC fees, clearing and settlement fees, intermediary markups, and insurance buffers.
Ultimately, Lewis concludes: If the SEC were to conduct a formal assessment of these costs and benefits, it would likely find that this safe harbor mechanism helps unlock the significant economic value inherent in tokenized securities.
As Chairman Atkins stated, tokenization "reshape the financial system as we know it." The SEC has expressed support for this direction through "Project Crypto," joint guidance documents, and other means.
But to truly realize this vision, a clear and effective regulatory framework still needs to be established for those blockchain applications that support peer-to-peer trading. This is precisely the goal of this safe harbor proposal, and Professor Lewis's analysis also shows that its overall economic logic is sufficiently convincing—despite trade-offs, the benefits are likely to outweigh the costs.
Lewis has charted the path; we look forward to the Commission moving forward along it.
