Stellar's stablecoin ecosystem expanded significantly in the first half of 2026. Three new dollar-denominated stablecoins launched on the network, each with a different design, regulatory status, and target market. Combined with the existing USDC presence, Stellar now offers four distinct approaches to dollar-denominated digital assets.

This article examines what each new stablecoin offers, how they differ, and what the expanding stablecoin stack means for developers building on Stellar.

Key Takeaways

The Four Stablecoins

YLDS: Yield-Bearing Dollar on Stellar

YLDS, issued by Figure, launched on Stellar on May 5, 2026. It is the first SEC-registered yield-bearing dollar product available on the network.

How It Works

YLDS pays holders a yield tied to the Secured Overnight Financing Rate (SOFR) minus 0.50%. As of mid-2026, SOFR sits at approximately 4.3%, making the YLDS yield roughly 3.8%. Yield accrues daily and is distributed to holders automatically.

The SEC registration means YLDS is classified as a security, not a payment token. This distinction matters:

Why It Matters

Traditional stablecoins like USDC pay no yield to holders. The interest earned on reserves goes entirely to the issuer. YLDS changes this by passing reserve yield through to token holders.

For institutional treasuries holding dollar-denominated assets on-chain, YLDS offers a way to earn yield without leaving the Stellar network. Instead of moving funds off-chain to a money market fund and back, an institution can hold YLDS and earn a competitive rate while maintaining on-chain liquidity.

Stellar Context

YLDS is available on Stellar, Provenance, and Solana. Stellar's selection reflects the network's growing institutional presence, particularly after the DTCC tokenization announcement and the RWA market crossing $3.3B.

USST: Treasury-Backed Institutional Stablecoin

USST launched on Stellar on July 1, 2026, issued by STBL, a company co-founded by Reeve Collins (who also co-founded Tether). Over $3 million flowed onto the network shortly after launch.

How It Works

USST is backed by tokenized U.S. Treasury collateral. The initial backing asset is USDY (Ondo Finance's tokenized treasury product). STBL has announced plans to add additional collateral sources, including Franklin Templeton's BENJI fund.

The treasury-backed model differs from USDC's cash-plus-T-bills approach:

Why It Matters

USST's use of tokenized treasuries as collateral means the backing assets are themselves on-chain and verifiable. This is a step beyond traditional stablecoin attestations, where holders rely on periodic third-party reports about off-chain reserves.

For institutional users who need dollar liquidity on Stellar but want more transparency into reserve composition, USST offers a middle ground between USDC's simplicity and the full complexity of directly holding tokenized treasuries.

MGUSD: MoneyGram's Payments-Native Stablecoin

MoneyGram launched MGUSD on Stellar on June 2, 2026. Bridge (a Stripe company) serves as the GENIUS Act-ready issuer, M0 provides smart contract minting and burning infrastructure, and Fireblocks supplies custody.

How It Works

MGUSD is designed specifically for MoneyGram's payments network. It gives MoneyGram users a dollar-denominated digital balance accessible 24/7, convertible to local currency at MoneyGram's 475,000+ agent locations worldwide.

The infrastructure stack:

MGUSD Architecture:
Bridge (Stripe) -> Issuer (GENIUS Act compliance)
M0             -> Minting/burning smart contracts
Fireblocks     -> Institutional custody
MoneyGram      -> Distribution (475K+ locations)
Stellar        -> Settlement layer

Why It Matters

MGUSD transforms MoneyGram from a Stellar ecosystem partner into a Stellar-native stablecoin issuer. Previously, MoneyGram used USDC on Stellar for its digital wallet services. With MGUSD, MoneyGram controls its own dollar token, enabling:

Initially available in the United States, with international expansion planned. The international rollout is significant because MoneyGram's primary use case is cross-border remittances.

What the Expanding Stack Means

For Developers

Having multiple stablecoins on Stellar means developers can choose the right dollar asset for their use case:

For the Stellar Network

Multiple stablecoins increase the total dollar liquidity available on Stellar. More liquidity means:

Regulatory Positioning

Each stablecoin has a different regulatory approach:

This diversity means Stellar can serve users across different regulatory jurisdictions and compliance requirements. A European institution might prefer USST's transparency, while a U.S. consumer application might use MGUSD for MoneyGram integration.

The GENIUS Act Context

The GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins) is the U.S. federal regulatory framework for stablecoin issuance that advanced through Congress in 2025-2026. MGUSD's "GENIUS Act-ready" designation through Bridge means it is designed to comply with this framework from launch.

Key GENIUS Act requirements relevant to Stellar stablecoins:

As the regulatory framework solidifies, having GENIUS Act-compliant stablecoins on Stellar positions the network for regulated payment use cases in the U.S. market.
