Solana has announced the launch of a new market-making mechanism called the Parimutuel Market Maker (PMM), designed for permissionless prediction markets. The network said the mechanism is only possible on Solana, citing its high throughput and low latency. PMM is intended to address issues seen with traditional AMMs in prediction markets, including inefficient price discovery and poor capital efficiency for binary and multi-outcome event wagering. No specific launch date, integrations or data on TVL impact were disclosed.

Venice API said its inference platform now natively supports direct access to blockchain data on Base, Solana and Robinhood Chain. The company said developers can have AI agents automatically pull on-chain state when calling its inference service, without additional keys or authentication. It positioned the capability as lowering the barrier to integrating on-chain data for agent-based use cases such as automated trading, real-time monitoring and smart contract verification.

Ripple said the XRP Ledger now supports batch transactions, allowing multiple operations to be packaged and processed atomically as a single unit to streamline institutional OTC trading. The update is aimed at compliant OTC workflows under the DTCC framework and referenced broker code 0443 as a specific DTCC registration identifier, according to Ripple’s official account. Ripple said the technical change does not alter XRP’s tokenomics, while strengthening pathways for XRP’s use in institutional settlement, market making and custody services.

Cloudflare said it has integrated the X402 protocol, allowing AI agents to process bitcoin-based micropayments directly. X402 is a lightweight HTTP payment protocol designed for automated, small-value settlement between services. The protocol supports atomic payments without requiring on-chain transaction confirmations. The integration does not involve a new token launch, exchange listings, or an on-chain upgrade, instead adding protocol-level support through Cloudflare’s edge network.

The XRP Ledger is set to natively support atomic batch transactions, enabling multiple settlement actions to be executed as a single on-chain operation. The upgrade is designed to support institution-grade OTC trading and trustless cross-asset swaps involving issued debt, money market funds and national currencies. All of these functions would run directly on the XRP Ledger without relying on third-party bridges or smart-contract workarounds. The change broadens the network’s settlement capabilities and reliability for real-world financial use cases.

Bitcoin formally activated Segregated Witness (SegWit) on 2017-08-24. The soft-fork upgrade moved signature data out of the transaction body, increasing effective block capacity and fixing transaction malleability. The change laid groundwork for the Lightning Network, atomic swaps and more complex smart-contract designs as part of Bitcoin’s base-layer evolution. Despite the word “Today” in the headline, the piece is a historical review and does not describe any new trigger, fund flows, or regulatory or market-structure shifts.

Solami said its getMultipleAccounts endpoint now supports reading 1,000 accounts in a single call, up from Solana’s standard limit of 100. The change is designed to cut network round trips and speed up on-chain reads. It also reduces the amount of integration code developers need by allowing larger batch requests.

Ripple said its four-phase roadmap to make the XRP Ledger quantum-resistant has moved into Phase 2, which is now live. The initiative targets full network-wide quantum resistance by 2028 to address potential risks to existing cryptographic signature algorithms such as ECDSA. Ripple framed the effort as proactive infrastructure hardening rather than an emergency response and did not disclose specific technical details or a mainnet upgrade timeline. No announcements were cited of other public blockchains taking similar steps, and XRP was the only explicitly referenced asset in the statement.
