Stellar news today is dominated by the activation of Protocol 28, also known as the Adapter upgrade, which reached the mainnet after validators completed a scheduled vote on 16 September 2026 at 17:00 UTC. The network was running the new protocol by 17 September, making the upgrade the main recent development for Stellar and its Soroban smart-contract ecosystem.
At 01:18 UTC on 20 September, XLM traded at $0.1945, up +0.76% over 24 hours. Its market cap was $6.78B, ranking it #24, while 24-hour trading volume stood at $336.35M.
Stellar news today: What Protocol 28 changes
Protocol 28 introduces features designed to simplify smart-contract upgrades and data migration. CAP-85 enables externally managed contract executables, allowing multiple contracts that use a shared executable to move to updated code through one operation. CAP-86 adds sparse-map host functions intended to make contract data migration easier, while existing host functions remain unchanged.
The upgrade also includes consensus changes under CAP-83. Validators can progress through parts of consensus without waiting for complete transaction sets and can discard late or invalid sets. Stellar’s upgrade documentation says the changes are intended to support faster ledger closures and reduce variation in close times. Validators were advised to keep their clocks synchronized and use network time protocol services.
Stellar records a reported throughput milestone
Chainspect data cited by CryptoSlate showed Stellar averaging more than 211 transactions per second across 100 consecutive blocks on 17 September. The figure was described as the network’s highest sustained throughput on record.
The milestone should not be treated as an upgrade result by itself. Stellar is gradually enabling parallel transaction-set downloading, so Protocol 28 provides infrastructure for higher loads while some performance improvements are being introduced in stages.
The upgrade arrives as the network continues to handle tokenized assets and stablecoins. CryptoSlate reported that Stellar supported approximately $3.3 billion in tokenized real-world assets and nearly $884 million in stablecoin supply, providing context for why contract-management and migration tools matter to applications in payments and financial markets.
Social-media discussion on 18 and 19 September also focused on Pyth pricing infrastructure for tokenized equities, commodities and foreign exchange products. Posts connected XLM with institutional settlement and tokenized markets, but claims involving Securities and Exchange Commission activity, Depository Trust & Clearing Corporation initiatives, and a reported KO funding round were not confirmed by official Stellar or regulatory announcements.
