The stablecoin market in 2026 is no longer a two-horse race. USDC and USDT still account for the vast majority of supply, but PYUSD (PayPal) and RLUSD (Ripple) have established genuine positions — each with a distinct issuer model, regulatory status, and target use case. This comparison covers the four across the dimensions that matter most for businesses and developers: supply, reserves, licensing, redemption rights, and EU access.

USDC
Circle issued USDC in 2018 and has built it into the compliance-first stablecoin of choice for US and European institutions. Circle became a public company on the NYSE (ticker: CRCL) in June 2025, adding the disclosure obligations of public reporting to its existing regulatory stack. USDC reserves are structured conservatively: roughly 80% in the Circle Reserve Fund (short-dated US Treasuries and overnight Treasury repo, with weighted-average maturity under 60 days) and the remainder in cash at regulated US banks. Deloitte & Touche LLP publishes monthly attestations confirming reserves match or exceed circulating supply; the Reserve Fund files daily holdings with the SEC.
USDC is MiCA-authorised, making it the dominant regulated stablecoin on EU exchanges. For businesses that need to demonstrate regulatory compliance to auditors, investors, or regulators, USDC's disclosure depth is unmatched among the four.
USDT
Tether's USDT has been the largest stablecoin since 2015 and remains so by a wide margin. Its dominance comes from deep liquidity, early presence on Tron (where much of global retail stablecoin volume flows), and entrenched network effects in emerging markets across Asia, Latin America, and Africa.
Tether's reserve composition has evolved significantly since its disputed early years. Its Q1 2026 attestation from BDO Italy reports total assets of $191.7 billion against $183.5 billion in outstanding USDT — an excess equity of approximately $8.2 billion. US Treasuries represent roughly 80% of assets; the remainder includes repo agreements, gold (approximately $8 billion), Bitcoin (approximately $7 billion), and secured loans.
Tether has not pursued a US issuer licence or MiCA authorisation. Most EU-regulated exchanges delisted USDT for EEA customers in early 2025. For businesses reaching into non-EU emerging markets, USDT's network depth is hard to replicate; for businesses with EU regulatory exposure, its absence from compliant venues is a structural constraint.
PYUSD
PayPal's PYUSD is issued by Paxos — a NYDFS-regulated trust company that received OCC federal oversight in December 2025, making PYUSD the largest dollar stablecoin issued by a federally regulated entity. PYUSD's reserves are held in cash and short-term US Treasuries, with monthly attestations from Withum.
PYUSD's distribution lever is PayPal's ~400 million consumer accounts. PayPal expanded PYUSD to 70 markets in March 2026, the most significant distribution event in its history. Supply has grown rapidly — from under $1 billion in early 2025 to approximately $4 billion by mid-2026. In February 2026, PayPal launched PYUSDx, enabling developers to issue branded stablecoins backed 1:1 by PYUSD reserves.
PYUSD does not yet hold MiCA authorisation and is not currently available on regulated EU exchange platforms. Its regulatory advantage is in the US federal framework, not the EU.
RLUSD
Ripple launched RLUSD in late 2024 under a New York Department of Financial Services trust charter and has since expanded its regulatory footprint significantly. RLUSD secured a Luxembourg Electronic Money Institution licence in February 2026, enabling issuance and distribution across all 30 EEA countries under MiCA passporting rules. It also holds UK FCA approval.
RLUSD's reserves are held in cash and short-term US Treasuries with monthly attestations. Circulating supply is approximately $1.7 billion as of mid-2026, with roughly 76% on Ethereum and the remainder on the XRP Ledger. RLUSD's position in the EU puts it alongside USDC as one of the two MiCA-compliant major stablecoins, but at a much smaller scale.
Redemption rights
Direct redemption — the ability to return tokens to the issuer and receive dollars — is what separates a payment stablecoin from a tradeable token. All four issuers support redemption, but the accessibility differs:
- USDC: Direct redemption for verified business and developer accounts; Circle processes these programmatically.
- USDT: Redemption has historically required large minimums (formerly $100,000+) and KYC; Tether processes institutional redemptions. Retail users typically exit through exchange trades rather than direct redemption.
- PYUSD: Redeemable through Paxos for verified accounts; PayPal consumer users convert through the PayPal app.
- RLUSD: Direct redemption available for verified users.
All four on Tempo
On most blockchains, using multiple stablecoins requires managing multiple gas tokens and routing transfers through different pools. On Tempo, all four stablecoins operate under the TIP-20 standard, and the protocol's Fee AMM converts between any USD-denominated TIP-20 at transaction time. A payment app or payroll system built on Tempo can send USDC to one recipient, USDT to another, and RLUSD to a third — all within the same infrastructure — without the sender needing to source separate gas tokens for each. The chain is stablecoin-agnostic by design.
The bottom line
By scale: USDT for global reach and liquidity; USDC for volume in regulated Western markets.
By regulatory clarity: USDC (broadest US + EU coverage); RLUSD (EU MiCA + NYDFS); PYUSD (US federal via OCC); USDT (limited to settlement agreements, no EU access).
By EU availability: USDC and RLUSD are the compliant options; USDT is absent from most regulated EU venues; PYUSD is not yet MiCA-authorised.
By reserve transparency: USDC (monthly Deloitte, public company filings, daily SEC disclosures); PYUSD and RLUSD (monthly); USDT (quarterly).
