Payment stablecoin
A payment stablecoin is a dollar-pegged digital token used for transactions, payments, settlement, and cross-border flows, regulated in the United States under the GENIUS Act and classified as one of the five digital-asset buckets under the OCC/state regulatory perimeter.
A payment stablecoin is a dollar-pegged token designed for the velocity layer of digital money: transactions, payments, settlement, and cross-border flows. It is programmable, regulated, Treasury-backed, and designed for high turnover. In the report's framing, payment stablecoins are one of two layers in a two-layer digital monetary system, the velocity layer, with Bitcoin as the savings or base layer.
Under the March 17, 2026 SEC/CFTC joint interpretation operationalized through the CLARITY Act framework, "payment stablecoin" is one of five formal digital-asset categories, supervised by the OCC and state regulators. The GENIUS Act, signed in July 2025, sets the issuance rules: 1:1 dollar backing, reserves held in cash or short-term US Treasuries, monthly attestations, and OCC supervision for federally chartered issuers above $10 billion in issuance.
The stablecoin market has consolidated into two tiers, and the report argues the geographic split is the strategy. The onshore tier (USDC, USAT, PayPal USD, and future bank issuers) is regulated under GENIUS, OCC-supervised, sanctions-compliant by design, and built for US institutional and retail use, with reserves audited monthly and issuers domiciled in the United States. The offshore tier (USDT, roughly $187 billion market cap) is not authorized for US use, with Tether headquartered in El Salvador since 2024 and settlement running primarily on Tron, where transaction costs are pennies. Both tiers buy Treasuries and both extend dollar reach.
A defining property of payment stablecoins is that they can be frozen. Whether issued by Circle or Tether, every regulated or quasi-regulated stablecoin can be frozen by its issuer at the request of a sufficiently powerful authority. On April 23, 2026, Tether froze $344 million in USDT across two Tron addresses controlled by the Central Bank of Iran, executed at the request of the US Treasury's Office of Foreign Assets Control. It was the second-largest USDT freeze ever and the first state-linked freeze of that scale. Tether has coordinated with more than 340 law enforcement agencies in 65 countries, supporting over 2,300 cases and freezing more than $4.4 billion in assets.
This freezability is the structural distinction the report draws between payment stablecoins and Bitcoin. Stablecoins are dollar instruments with embedded enforcement; they inherit the dollar's depreciation and require trust in an issuer. Bitcoin, classified as a digital commodity, has no issuer to freeze it, no authority to reverse it, and a fixed supply determined by mathematics. The properties that make payment stablecoins ideal for the velocity layer are the same properties that make Bitcoin the base layer.

Why does Payment stablecoin matter?
It matters because the Stablecoin Stack separates regulated digital-dollar velocity from Bitcoin's base-layer monetary role. Onramp uses that distinction to explain where custody, issuer control, and regulatory classification affect institutional capital.
How does Payment stablecoin relate to Bitcoin custody?
It relates to custody because Bitcoin's digital-commodity role only helps allocators if the asset is held without a single-party control point. Onramp's Multi-Institution Custody distributes control across Onramp, BitGo Trust, and CoinCover.
