Stellar Weekly Roundup: Week of Sep 4, 2026

U.S. Bank completed the first live cross-border payment on Stellar using USBDC, its bank-issued stablecoin, with minting, redemption, freezing, and clawback controls running through the bank's core compliance and operations systems. MoneyGram's stablecoin-backed Visa card launched commercially in Colombia through Rain and Crossmint. Stellar's on-chain stablecoin supply crossed $1 billion, separate from the network's $4 billion in tokenized RWAs.

Institutional Adoption

U.S. Bank's USBDC completed its first live pilot on Stellar: a cross-border payment between a U.S. entity and a European counterparty. Minting, redemption, freezing, and clawback controls ran through the bank's core finance, risk, and operations stack. The bank announced the launch on September 9; CoinDesk covered the live cross-border payment test; Stellar.org published its account of the transaction.

The MoneyGram Card went live on Rain in Colombia. Rain provides card infrastructure, Crossmint the wallet layer, and Stellar settles transactions. The product targets MoneyGram's recipients rather than senders: users hold stable dollar balances and spend directly across 175 million Visa merchant locations without conversion. MoneyGram credited all three partners on launch day.

Tala and Crossmint announced a partnership embedding Tala's credit engine into wallets built on the Crossmint platform, with Tala managing underwriting, balance sheet, and risk. Stellar.org's government debt tokenization post circulated widely on September 7.

Stablecoin Expansion

USDT0 is now bridgeable directly from Ethereum to native Stellar in a single transfer. BuildOnStellar demonstrated the route on September 10. This follows Kraken adding USDT0 deposits and withdrawals on Stellar, announced on September 4, days after USDT0 launched via LayerZero.

Stellar's on-chain stablecoin supply crossed $1 billion, per analyst u/boxthebuilder citing the Stellar Light stablecoins dashboard on September 5. The milestone sits separately from the $4 billion in tokenized RWAs tracked on the network.

DeFi and Developer Infrastructure

Pyth Pro and Pyth Indices launched on Stellar, delivering 3,500-plus live price feeds across equities, commodities, FX, and crypto with updates as fast as 50 milliseconds. Pyth Indices enable continuous asset pricing outside exchange hours, filling a gap for Stellar's $4 billion RWA market.

LOFI presented a Blend v3 candidate built in response to the Comet LP pool exploit. The proposal introduces tiered backstops with junior and senior tranches, XLM as the emitter swap token to remove USDC as a single point of failure, and clawback support for compliant asset issuers, while preserving Blend's permissionless and immutable design.

At the protocol level, a discussion reopened CAP-0043, which would add secp256r1 signer support to classic Stellar accounts. The argument: Android StrongBox and Apple CryptoKit both expose P-256 ECDSA but not Ed25519, meaning Stellar signing keys currently cannot reside in hardware secure elements. The week's protocol commits added a SEP-57 muxed address event and a new CAP proposal workflow. The Soroban SDK will also shift spec output to fully qualified type paths, eliminating name collisions in complex contracts.

Arcane and Predicate published a joint piece on the compliance stack they are building for private financial applications on Stellar, covering pre-screening, policy enforcement, and governed evidence disclosure for investigation or regulatory purposes.

Community and Regional Activity

The September SCF Demo Day featured three funded projects shipping live products. ZIG3 demonstrated a passkey-based smart wallet with liquid staking and play-to-earn games. Vottun and Wirex released a seven-module payment SDK that reduces stablecoin integration from weeks to minutes, including X-402 infrastructure for autonomous agent payments. KindFi showcased its crowdfunding platform for Central American causes. SCF's Build Awards program has distributed $14.6 million XLM across five 2026 rounds.

Tellus Cooperative opened a Blockchain Hub in Santiago with SDF support, providing permanent workspace for Chile's Web3 community. Runtime Verification announced five weeks of Stellar Security Office Hours starting September 15, offering free 1:1 Soroban security and protocol design sessions open to all teams building on Stellar.

Stellar Weekly Roundup: week of Aug 14, 2026

Marketnode will bring BNY Investments asset management funds onchain via Stellar, as the network's RWA active market cap reached an all-time high of $2.57B and Spiko's eurSAFO fund crossed $1.1B. SCF #45 closed with 213 submissions, the largest round in the program's history, while SCF #46 opened with a November 8 deadline. Merkl launched its first fixed-APR campaigns on Stellar through Upshift vaults curated by Gami Labs.

Sovereign Debt and Fund Tokenization

Stellar has held the lead in tokenized non-US government debt since February 2026, with $490M in sovereign instruments from issuers including Etherfuse, Spiko, Ondo, Franklin Templeton, and Circle. A post published this week documents the category's growth from roughly $500M in early 2025 to $3B by June 2026, citing Stellar's multi-currency design, protocol-native compliance tooling, and USDC liquidity access.

Marketnode's partnership with BNY Investments extends institutional tokenization into APAC asset management funds. Spiko's eurSAFO crossing $1.1B in the same week pushed Stellar's reported RWA active market cap to the $2.57B all-time high. SDF Chief Commercial Officer Jose Fernandez da Ponte wrote from Stellar House São Paulo that durable global financial services are built first on local regulatory and market realities, then connected to global liquidity, a model Stellar's permissionless infrastructure supports.

DeFi and Yield Infrastructure

Merkl launched its first incentive campaigns on Stellar through Upshift vaults curated by Gami Labs, with Turtle providing additional support. Depositors earn reported fixed APRs of 10% on USDC and 5% on XLM. Merkl's model monitors realized vault yields in real time and tops up shortfalls to maintain the stated rate rather than emitting variable rewards. Blend Capital publicly acknowledged the campaign.

Peridot Finance launched margin trading on testnet with a competitive leaderboard, and shipped an AI agent for DeFi portfolio management earlier in the week. Both remain testnet-only.

Balanced published notice that all v1 loans will be liquidated after December 1; users with bnUSD positions should repay or migrate to Balanced v2 before that date.

Developer Infrastructure

The August 20 Stellar Developers Meeting compared six wallet integration paths for dApp builders: Stellar Wallet Kit, Blux, Privy, Para, Passkey Kit, and Smart Account Kit. SDF Developer Advocate Kahn demonstrated account creation, funding, and transaction signing across each approach. The session also confirmed the Protocol 28 testnet upgrade for the following week; production configurations pinned to Protocol 27 should be updated.

Runtime Verification completed a security audit of Moonlight, a UTXO-based privacy-payment infrastructure developed by The Aha Company. The two-week engagement surfaced three medium-severity and a dozen informative findings, all addressed or acknowledged. Trustless Work joined SCF's official Integration Track as a recognized ecosystem building block. Active protocol discussions this week include post-quantum signature verification host functions and an externally managed contract executable type for Soroban.

SCF and Community Programs

SCF #45 drew 213 submissions, the largest round on record. The SCF team noted the volume will extend review timelines; panel review runs approximately 10 days, and the Community Vote is expected to open around September 2 for about one week. SCF #46 opened simultaneously with a November 8 submission deadline and updated handbook requirements at stellar.gitbook.io/scf-handbook.

Stellar's InstAward program funded 10 Turkish builders with $50,000 total across remittance infrastructure, P2P trading, privacy tools, dev tooling, DeFi vaults, micropayments, and AI-assisted workflows. Stellar Community Growth applications are open through August 28 for a Giveth QF round running September 21 to October 4, with community events funded November 1-30.
