FDUSD vs. PYUSD vs. RLUSD in 2026: Which New Stablecoin Is Actually Worth Holding?

After USDT and USDC, the new stablecoin issuer story has been running for years. By mid-2026 three names get listed together most often: FDUSD (First Digital USD), PYUSD (PayPal USD), and RLUSD (Ripple USD). FDUSD sits behind only USDT in depth on Binance non-USDT pairs, PYUSD has its own niche inside the PayPal and Venmo apps, and RLUSD — which only received its New York DFS license at the end of 2024 — is betting on cross-border remittance. This piece lines up the three new stablecoins by issuer background, reserve structure, compliance path, use case, and the most likely failure mode.

One-line positioning

• FDUSD: issued by First Digital Trust in Hong Kong, born out of a 2023 Binance strategic partnership, now the dominant non-USDT quote currency on Binance. Roughly $2.5 B in supply by mid-2026.
• PYUSD: co-issued by PayPal and Paxos, running on Ethereum and Solana, the internal stablecoin of the PayPal/Venmo ecosystem. Roughly $1.2 B.
• RLUSD: issued by Ripple’s Standard Custody subsidiary under a New York DFS limited-purpose trust charter, live since December 2024, deployed on XRPL and Ethereum and aimed at cross-border remittance firms. Roughly $900 M, fastest growth of the three.

The issuer structures are nothing alike

First Digital Trust is a Hong Kong trust company. It holds a Hong Kong trust license but is not a bank and does not hold a full financial-services license. FDUSD’s reserves sit in bank and short-Treasury accounts held by First Digital Trust. That structure went largely unexamined in 2023, but in April 2025 Justin Sun publicly questioned FDUSD’s reserves on X, FDUSD briefly depegged to $0.87, and a small-scale run kicked off. First Digital responded with more audit disclosure and the peg recovered, but the trust wound did not heal cleanly.

PayPal is not the issuer either. It outsources issuance to Paxos Trust Company, the New York DFS-regulated trust that previously issued BUSD (regulators forced minting to stop in 2023) and USDP. PayPal supplies the brand and the user funnel; Paxos supplies the compliant issuance plumbing. This split-role design lets PayPal avoid direct issuance risk, but it also means that if Paxos hits a problem, PYUSD stalls too.

Ripple’s RLUSD took a third route. Ripple’s subsidiary Standard Custody & Trust Company received a New York DFS “Limited Purpose Trust Company” license and gained the right to issue RLUSD in December 2024. RLUSD is therefore issued directly by Ripple — no two-layer split as with PYUSD. That structure is tighter on compliance, but it also transmits Ripple’s own legal risk to RLUSD. The Ripple/SEC case settled in 2024, yet institutional opinion on Ripple’s legal posture is still divided.

Reserve composition

RLUSD has the cleanest reserve construction of the three — under the NY DFS trust charter Ripple cannot hold commercial paper, corporate debt, or use offshore bank custody. That is the same rulebook that pushed Tether out of New York years ago. PYUSD is nearly as strict because Paxos is also under DFS. FDUSD’s rules are looser — Hong Kong trust law does not require 100% short Treasuries, which is one structural reason behind the April mini-depeg.

Use cases diverge — three different markets

FDUSD’s base is the exchange. Binance pushed FDUSD hard with zero-fee trading pairs across 2023–2024 and made it the deepest non-USDT pair on the venue. But that depth is single-channel — outside Binance, FDUSD is barely listed on Coinbase or Kraken. The fate of “single-channel” stablecoins has already been rehearsed with BUSD.

PYUSD’s base is the PayPal ecosystem. PayPal has tens of millions of active users in the U.S., and Venmo penetrates deeply into the 18–35 cohort. The defining feature of PYUSD is “send to a friend inside the PayPal app” — a payment surface no other stablecoin has. In 2025 PayPal integrated PYUSD into its merchant settlement API, letting SaaS companies receive PYUSD revenue. PYUSD’s on-chain DeFi presence is still thin — an Aave pool exists, but depth is limited.

RLUSD bets on cross-border payments. Ripple’s core customers for years have been banks and remittance firms — Tranglo, Travelex, SBI Remit and similar. After launch, Ripple wired RLUSD into Ripple Payments (formerly ODL) as a replacement for using XRP as the bridge currency. For a cross-border payments firm, RLUSD is more attractive than USDC because Ripple already has compliance corridors in 70+ countries.

The single largest risk for each

• FDUSD’s largest risk is “Binance changes its preferred quote stablecoin.” If Binance one day promotes another house-affiliated stablecoin, FDUSD liquidity halves overnight. Not hypothetical — when Binance briefly leaned into TUSD in early 2024, FDUSD got squeezed.
• PYUSD’s largest risk is “PayPal’s internal priorities.” PayPal is a listed company; management turnover, strategy reset, or a shift in crypto stance directly affects PYUSD investment. Paxos’s earlier BUSD case is a reminder that a single regulatory letter can stop an issuer overnight.
• RLUSD’s largest risk is “supply too small, liquidity too thin.” $900 M does not yet support a deep mainstream DEX pool, and concentrated redemptions amplify price moves. Markets also benchmark RLUSD stability against Ripple’s own volatility.

Which would I pick? It depends on the use

• Trading on Binance: using FDUSD as the quote currency is fine, but don’t sit in it long-term. Cycle back to USDC or USDT after the trade.
• U.S. retail, heavy PayPal user: PYUSD has real in-app convenience for small amounts.
• Cross-border payments, bank rails needed: RLUSD is the most institutionally friendly of the three, but only if your counterparty also supports it.
• Want maximum on-chain liquidity: none of the three beat USDC. Stick to USDC, or use the logic in /en/tutorial/usdc-vs-usdt-comparison.html.

New issuers won’t replace the giants, but they will bite off chunks

USDT and USDC are not getting replaced in the short term, but the stablecoin market will increasingly look like the card network market — Amex and Discover beside Visa and Master, each owning specific channels and use cases. FDUSD serves Binance users, PYUSD serves PayPal users, RLUSD serves cross-border remittance firms. Understand who each issuer’s real customer is and you can judge whether you should hold it and how much. The next stablecoin to be culled is unlikely to be USDT — it will probably be an issuer that never decided what it was for — and that is worth thinking about now rather than later.
