Stellar Weekly Roundup — week of May 29, 2026

MoneyGram launched MGUSD, a native U.S. dollar stablecoin on Stellar, on June 2, putting Stellar at the center of payment flows for 60 million active customers at 500,000+ retail locations. The SDF published the Protocol 27 "Zipper" upgrade guide, setting a July 8 mainnet vote with SDK releases starting June 5. The Stellar Development Foundation also joined the United Nations Development Programme's new 26-member Blockchain Advisory Group focused on financial inclusion.

MoneyGram Goes Native with MGUSD

MGUSD is issued by Bridge (a Stripe company) and minted through M0 infrastructure, embedded as a self-custodial wallet inside MoneyGram's consumer app. Customers can store dollars on-chain, send across borders, and withdraw cash at the MoneyGram agent network without managing seed phrases. The launch transitions MoneyGram off Circle's USDC for its core settlement layer, deepening a five-year partnership with SDF. The Block, CoinDesk, and PR Newswire all covered the announcement. MoneyGram CEO Anthony Suhu discussed the stablecoin strategy on the Deep Dive Podcast, and Denelle Dixon covered both the MGUSD launch and DTCC integration in an interview with Paul Barron Network.

Institutional RWA Infrastructure

Stellar's tokenized real-world asset stack crossed $2.8 billion, a 3.5x increase since late 2025, with 1,700 monthly active developers placing it fourth among all blockchain ecosystems, per Messari's State of Stellar Q1 2026 report.

RedStone published SEP-40, Stellar's standard interface for oracle consumers, with nine assets now live: stablecoins, sovereign debt, and Bitcoin products. Lending markets and derivatives platforms can now consume unified pricing data without per-protocol custom integration work. Separately, tZERO's SEC-registered custodian added USDM1, a Marshall Islands sovereign bond backed 1:1 by U.S. Treasuries, enabling institutional on-chain collateral within a regulated framework with 24/7 settlement.

WisdomTree's WTGXX tokenized money market fund, available on Stellar at a $1 minimum with 24/7 subscriptions, reached $700 million AUM with 6x year-over-year growth, according to WisdomTree's Jeremy Schwartz and Meredith Hennon on the Pantera Capital podcast.

Protocol 27 and Developer Security

The Protocol 27 "Zipper" upgrade guide introduces authentication delegation for smart accounts under CAP-0071, which streamlines multisig and reduces transaction costs. SDK releases run June 5-11, testnet upgrade June 18, mainnet vote July 8. Developers must review breaking changes before the vote.

Inferara completed its third SCF milestone, delivering the Inference formal verification language for Soroban. The toolchain enables developers to mathematically prove smart contract correctness with imperative syntax. Nectar Network received a $75K Build award from SCF #42 for a liquidation protocol that replaces single-operator bots with pooled capital and competing staked operators. It is live on testnet.

Agentic Commerce

Stellar's x402 payment protocol and Brale demonstrated a live integration at Day Zero: services sold to AI agents in 30 lines of code, with an agent autonomously making a purchase on Stellar, paired with a quickstart guide in the Stellar docs. Defindex's Interoperable series, Chapter 7, with Crossmint and OpenSettling, covered embedded finance, smart wallets, and agent-to-agent transactions, framing stablecoins as the operating layer for machine-to-machine commerce.

A guest article on LumenLoop by @notishansingh argues for native perpetual futures on Stellar, with Zenith Protocols building toward that use case.

SCF, Community, and Governance

SCF #43 closed with 29 projects funded across 85 submissions, distributing $3.14M XLM through three tracks: Open, Integration, and RFP. The referral program sourced 22 of the 29 winners. Stellar West Africa confirmed 10 West African projects received funding in SCF #43, totaling more than $1 million collectively.

The UNDP launched a 26-member Blockchain Advisory Group including SDF, with the inaugural meeting focused on financial inclusion and blockchain's role in expanding access to financial services.

SDF held a public Reddit AMA on June 2 with Denelle Dixon, Jose Fernandez da Ponte, and Tomer Weller. At Stable Summit, Tomer Weller discussed what he described as "insane" RWA growth on Stellar this year.
