The SEC Isn't Waiting on Congress to Rewrite Crypto Custody

Chair Paul Atkins backs the Clarity Act, then makes clear the SEC's own rulemaking doesn't need it to pass

2026-09-15 · 3 min read

SEC Chair Paul Atkins told Congress to "vote to advance the Clarity Act and send it to the president's desk as soon as possible." Then, in the same breath, made clear the agency isn't waiting around to find out if it will. The Digital Asset Market Clarity Act — sweeping crypto market-structure legislation — hit a Senate cloture vote this week with Polymarket pricing its odds of becoming law by Monday at 17%. Atkins' agency is proceeding on three rulemaking tracks in parallel, with or without it.

That's the actual story here, and it's the one builders should read closely: US crypto regulation is becoming less a single bill and more a set of agency actions that move at their own pace. If you're building an agent that touches custody, trading, or tokenized assets, the rules arriving via SEC rulemaking will land before — or regardless of — whatever Congress does with the headline bill.

The three pieces of "Project Crypto"

Atkins framed the SEC's push under three pillars:

  • Regulation Crypto Assets (proposed). Atkins called it one of the agency's most significant modernization efforts — aimed at giving entrepreneurs more certainty when raising capital through digital assets domestically, instead of structuring around US securities law.
  • Transfer agent rules, rebuilt. The rules governing transfer agents — the entities that maintain ownership records for securities — haven't been substantially updated in roughly four decades. The SEC's overhaul would formally recognize blockchains as valid ledgers for tracking ownership of tokenized securities. That's the plumbing change that matters most for anything calling itself a "tokenized asset" today: it's the difference between a chain that merely *represents* ownership and one the SEC treats as the actual record.
  • A crypto custody framework for investment advisers. Atkins directed SEC staff to draft a proposal letting investment advisers self-custody crypto assets, or use state trust companies, under defined conditions. His stated reasoning is blunt: qualified third-party custodians simply don't exist yet for a lot of digital assets. That's an admission that the infrastructure the current rules assume — a mature, regulated custodian for every asset class — hasn't caught up with the assets people are actually holding.

Why this matters if you're building an agent that touches money

Custody is not an abstract compliance topic for onchain agents — it's the whole ballgame. An agent that can move funds is, functionally, a custodian of whatever it's holding between actions, even for a few blocks. If the SEC formally opens the door to self-custody arrangements for regulated advisers, the shape of "acceptable custody" for advised crypto portfolios gets a lot more concrete than it is today — and that shape will eventually set the bar every custody-touching product gets measured against, agents included.

The transfer agent rewrite matters for a quieter reason: it's the rule that decides whether a blockchain record of who owns what actually counts, legally, as the record. An agent trading tokenized securities on a rail the SEC doesn't recognize as authoritative is trading on vibes. An agent trading on a rail the SEC does recognize is trading on infrastructure. That distinction is exactly the kind of thing "self-reported" vs. "verified" is built to catch — claimed compliance and demonstrated compliance are not the same sentence.

None of this is settled. It's a proposal, a directive to staff, and a bill still short of the votes to pass. But it's the SEC's own agenda, moving on the SEC's own timeline, and that timeline doesn't run through the Senate.

What to watch

Watch for the actual text of the Regulation Crypto Assets proposal and the custody framework once staff publish drafts — that's when "self-custody under specified conditions" turns into a checklist a builder can actually read against. Also worth tracking: the pushback. Eight banking groups are pushing for tighter stablecoin restrictions, and 18 state attorneys general have warned the Clarity Act could undercut their fraud-prosecution authority. Whatever passes, if anything does, will be shaped by that friction as much as by Atkins' own priorities.
