The Blockchain Association has backed the U.S. Treasury Department's proposed GENIUS Act rules for stablecoin issuers, a rulemaking that would set federal standards for how payment stablecoins are issued, offered, and sold. The proposal marks the first concrete implementation step toward a compliance framework for the issuers that underpin much of DeFi's dollar liquidity.

Three points frame the development: the Blockchain Association supports Treasury's proposed GENIUS Act rules governing payment stablecoin issuance; the rules are a proposal, published in the Federal Register, and are not yet final; and the rulemaking targets how stablecoin issuers issue, offer, and sell payment stablecoins.

What the Blockchain Association supports

The proposal comes from the Treasury Department, which announced the rulemaking tied to the GENIUS Act in an official press release. The core of the news is the trade group's endorsement of that regulatory framework rather than opposition to it.

The rulemaking itself is titled "GENIUS Act Regulations on Payment Stablecoin Issuance, Offer, and Sale," per the text filed in the Federal Register on August 18, 2026. In practice, that scope — issuance, offer, and sale — defines which activities issuers would need to bring into compliance.

For a group that represents crypto industry participants, backing a Treasury proposal signals alignment on the substance of oversight for the dollar-pegged assets that settle much of on-chain trading, including collateral used across lending markets and AMMs.

Why the proposal matters for stablecoin issuers

Payment stablecoin issuers are the parties directly in scope. The rulemaking's framing around issuance, offer, and sale means the operational touchpoints most affected are the primary market functions issuers control, according to the Treasury docket TREAS-DO-2026-0496.

Federal standards for these activities can raise compliance and reporting obligations while also giving issuers clearer operating rules, a tradeoff that matters for any entity minting dollar tokens at scale. That clarity also matters for exchanges, lenders, and DeFi protocols that use those tokens as settlement and collateral, because changes at the issuer level can flow through the wider market infrastructure built around stablecoins.

The brief does not contain reserve, licensing, or supervision specifics beyond the rulemaking's stated scope, so issuer-level requirements remain to be read from the proposed text rather than summarized here.

What comes next in the Treasury rulemaking process

These are proposed rules, not final ones. The publication in the Federal Register opens the standard path toward a comment period before any final rule takes effect.

Stakeholders, including the Blockchain Association, can submit input through the same Treasury docket, which is where trade-group support translates into influence over the eventual final language. The relevant items to monitor are the comment deadline and any revisions Treasury issues in response.

The outcome will shape the regulatory baseline for payment stablecoins in the United States, and by extension the dollar liquidity layer that DeFi protocols depend on, from lending collateral to LP pairs across major venues. Both the issuers that mint those tokens and the protocols built on top of them therefore have a direct stake in the final language.
