DeFi stakeholders push SEC for clarity on interfaces as Ethereum mulls privacy layer

The DeFi Education Fund (DEF) and 35 co-signatories, including a16z crypto, Aptos Labs, Uniswap, Chainlink, Paradigm, Solana Policy Institute, and Phantom, among others, have petitioned the Securities and Exchange Commission (SEC) to convert its recent staff guidance on DeFi interfaces into durable notice-and-comment rulemaking.

In another development, Ethereum developer Tom Lehman published a draft proposal, EIP-8182, on X. The proposal calls for native private transfers to be embedded into the Ethereum protocol.

Both events are likely going to impact how the SEC rulemaking matches the pace of innovation in the crypto space.

What did the SEC’s April guidance on DeFi interfaces say?

The SEC’s Division of Trading and Markets issued a staff statement on April 13 that exempts certain crypto trading interface operators from registering as broker-dealers.

The exemption covered operators of front-end interfaces connecting to DeFi protocols through which users control their own funds.

The guidance permits covered UI providers to receive transaction-based compensation from users without having to register as broker-dealers.

Why are DeFi stakeholders pushing for formal rulemaking now?

The April 13 guidance from the SEC is an interim staff statement that will be considered withdrawn after five years from its publication date unless the Commission states otherwise or makes it a rule.

The DEF and its co-signatories are asking the Atkins SEC to lock that position down through formal rulemaking so that it cannot be undone by a future commission with different policy priorities. Anyone who lived through the SEC under Gary Gensler would understand the urgency to implement formal rules.

The signatories cautioned that regulatory ambiguity could become a drag on blockchain development and reduce market access for investors.

How does Ethereum’s own privacy architecture complicate the current guidance?

If adopted, the EIP-8182 draft proposal would make private transfers a native feature of Ethereum itself.

The proposal would add a shared shielded pool directly into Ethereum as a system contract, with a ZK proof-verification precompile.

Ethereum co-founder Vitalik Buterin has been down this path before in April 2025. Back then, Vitalik proposed that wallets should integrate privacy tools like Railgun so that users could manage shielded balances without adding any third-party tools.

The pool that is being proposed in EIP-8182 would carry no admin key, no governance token, and no on-chain upgrade mechanism. It would just evolve through Ethereum’s hard-fork process.

As the Ethereum network considers this proposal, there is also the perspective of how native privacy at the protocol level would impact the category of non-custodial interfaces the Commission has just attempted to define.

A shielded pool built into Ethereum would make it relatively harder for any future regulator to draw broker-dealer lines around front-end wallets offering private sends as a default feature.
