Solana Weekly Recap (October 11, 2026): 200ms Slots, Samsung Wallet, Securitize Stocks

The week had four themes. Mainnet-beta has been running 200-millisecond slots since epoch 1053, Anza published an Alpenglow page with no mainnet date, and a discussion in the SIMD repository proposes raising the block limit again. Samsung announced USDC transfers in its wallet, and x402 batch settlement is available through PayAI and BlockRun. Securitize launched tokens on twelve U.S. stocks, ESMA set out expectations on non-compliant stablecoins, and BNY announced SOL custody for selected EU institutions. Orca and Loopscale merged, Marinade and Sanctum opened new products, and the Pyth DAO directed product funds into its reserve. We summarize and link to our full coverage for each.

Infrastructure

• 200ms slots: Mainnet-beta has been running 200-millisecond slots since the boundary of epoch 1053 on October 9. Anza confirmed the change. The sequence is 400, 350, 300, 250, and 200 milliseconds. At 200ms, the block limit is 50 million compute units. Five slots fit in one second, and an epoch lasts about 24 hours. → Read the story
• Alpenglow page: Anza presents Alpenglow on a single page. Testnet is marked complete as of September 24, devnet as of September 25. Mainnet-beta is marked upcoming. There is no date. The page names SIMD-0384 as the migration gate. The top of the page states 150-millisecond finality. It does not give a mainnet measurement. → Read the story · Alpenglow status
• Jito before activation: The October 9 changelog names several client versions for the period before Alpenglow, and they do not match. BAM nodes go into maintenance mode beforehand and fall back to the ordinary Jito-Agave block engine. No activation epoch is given. Mid-October is Jito’s reading in that changelog, not a date from the Anza or Foundation texts. → Read the story
• Proposal to raise the block limit: Brennan Watt of Anza opened a discussion in the SIMD repository on October 10 under the name bw-solana. Compute units per block would rise from a 50-million baseline through five feature gates: 60, 70, 80, 90, and 100 million. The shred limit and the per-account limit would stay the same. He cites replay headroom, little headroom in linearized execution (currently 20 million compute units on 200ms slots), and unclear network-bandwidth headroom. There is no SIMD and no date. → Discussion in the repository

Payments

• Samsung Wallet: From the last week of October, eligible Galaxy users in the United States can send USDC in Samsung Wallet. Samsung names Solana and Sui. Samsung does not present this as an exclusive partnership with Solana. Custody runs through Bastion, and Coinbase is the sub-custodian. The release counts 82 million devices, not users. Samsung charges no fee for transfers to wallets. The service is not available in the EU. → Read the story
• x402 batch settlement: On October 7, batch payments on Solana became available through PayAI and BlockRun. An agent deposits a ceiling, authorizes each use with a signature, and settles in aggregate. The figure of more than 1 million payments per second comes from a Foundation proxy test, not from a measured network load. PayAI calls the offering a public preview. → Read the story

Securities and Regulation

• Securitize Stocks: On October 8, Securitize launched tokens on twelve U.S. stocks on Solana, including Apple, Microsoft, Nvidia, and SpaceX (SPCX). Per the release, each token is backed 1:1 and is a security entitlement under UCC Article 8. Trading settles in USDC after KYC and is not around the clock at the start. The release names the United States, the EU, and other permitted jurisdictions. Switzerland is not in the EU. The release writes GOOG for Alphabet; the catalog lists GOOGL. → Read the story
• Solana DvP: On October 6, the Solana Foundation introduced an open-source escrow program for delivery-versus-payment. The security and the cash are meant to change hands in the same transaction. If that does not happen for both, it happens for neither. The program supports SPL Token and Token-2022. Per the release, J.P. Morgan provided input on settlement practices. The Foundation writes that the bank does not develop, operate, or approve the program. The Foundation is looking for design partners ahead of the production release. The same release says the program has been externally audited and is ready for use with real funds. → Announcement
• ESMA: On October 8, ESMA published opinion ESMA75-113276571-1742. Providers authorised under MiCA are expected to stop services in non-compliant stablecoins for customers in the EU. Existing holdings are expected to be wound down within three months of October 8. The opinion names no token and no network. It is not an amendment to MiCA. → Read the story
• BNY: On October 8, BNY announced custody of, among other assets, SOL for selected institutions in the EU. The release names BTC, ETH, SOL, and USDC. The list is not marked as closed. It does not describe a retail offering. In the ESMA register, file dated October 7, the only country listed is Belgium. → Read the story

DeFi

• Formation: Since October 7, Orca and Loopscale have operated together as Formation, based in New York, with Luke Truitt as CEO. Both apps keep running. Positions, loans, and vaults stay as they are. No one has to move funds or sign again. Per the press release, Orca has processed more than $550 billion in volume since 2021. That figure is self-reported. A short profile in the same release gives a lower number. → Read the story
• Marinade Borrow: Marinade has opened Borrow. Users can borrow USDC or SOL against stake accounts, mSOL, or SOL without unstaking first. Each loan runs through Kamino or Jupiter Lend. Interest is variable. A position can be liquidated if the loan-to-value ratio crosses the market’s threshold. → Read the story
• swSOL: On October 9, Sanctum introduced wrapped SOL. Part of the pool stays liquid, and the rest is staked through a liquid staking token. The documentation does not name which token that is. Staking rewards go to the protocols that integrate swSOL, not to merely holding it. Per Sanctum, swSOL is not a liquid staking token. 1 swSOL is meant to remain 1 SOL. → Read the story
• PYTH reserve: Under the passed proposal OP-PIP-136, the Pyth DAO uses all funds it receives from Pyth products to buy PYTH for the reserve. For the third quarter, Pyth reports $11.49 million in ARR and 276 paying accounts. Those are Pyth’s figures, not an audited statement. → Read the story

Short Notes

• WLD via Sunrise: The official Solana account reported that WLD from World Network is available on Solana via Sunrise. Raydium wrote that the token is tradable there. No announcement from Sunrise or World Network with a mint address was available at the time of writing. → Read the story
