The messaging protocol XMTP founder Shane Mac stated that XMTP will evolve into a self-operating open-source messaging stack, providing private conversations between people and agents, with infrastructure controlled by users, without requiring tokens or wallets. The network hosted by XMTP Labs will shut down in early 2027.Shane Mac mentioned that he founded XMTP five years ago because he believed that private messaging should not be owned by a single company. He recalled that the team envisioned using wallets as cross-application identities, allowing messages to follow identities, and using tokens to pay infrastructure operators, but this path was not realized. XMTP has never issued tokens and will not issue them now. He admitted that it was a wrong decision to persist with a single shared network for a long time, as developers have consistently requested the ability to self-host XMTP. Therefore, it has shifted to self-hosting, allowing developers to use, inspect, modify, and maintain the entire software suite without relying on Labs. Former employees will assist in maintaining the protocol, and Shane Mac himself will continue to be involved.The article introduces that self-hosted XMTP offers quantum-resistant end-to-end encryption, private one-on-one and group chats, encrypted identities, and message authenticity, as well as SDKs for mobile, web, server, and agents. Chief Technology Officer Nick Molnar has simplified the backend to a single Rust binary and integrated attachments, push notifications, handles, and signed webhooks for new messages. Each self-hosted network does not automatically interconnect by default, and agents from different tools must connect to the same backend to share conversations.

Alex Gluchowski, CEO of Matter Labs, announced Prividium Commander at Money20/20 USA, pointing out that while most banks have tested blockchain, only a few have truly put it into production services. The crux of the issue lies in operational processes rather than the technology itself, including aspects such as issuance control, transfer processing, audit requirements, and compliance workflows.Prividium Commander is positioned as a unified control plane, allowing institutions to manage permissions, configure token functionalities, and set operational strategies all in one place, while also integrating with existing traditional financial systems of banks and being compatible with both public and private chain infrastructures. This product is built on Matter Labs' permissioned privacy blockchain platform, Prividium, which is based on ZK Stack technology, allowing institutions to run private chains on their own infrastructure and anchor transactions to Ethereum through zero-knowledge proofs, achieving Ethereum-level settlement finality without disclosing customer balances and transaction details.Matter Labs open-sourced the Prividium Core permission engine in September 2026, with the Deutsche Bundesbank being the first testing party. Cari Network has chosen Prividium to build a multi-bank tokenized deposit platform, with participants including regional banks such as Huntington and M&T Bank, planning to go live later in 2026. By mid-2026, Matter Labs had fully shifted its focus to the institutional privacy infrastructure of Prividium.

BitGo announced the establishment of a new research and innovation department, BitGo Labs, aimed at designing, launching, and validating the next breakthrough applications in the digital asset space. BitGo stated that this department focuses on use cases that can only be achieved through cryptographic technology, such as interest rates and yields that traditional systems cannot provide, and utilizes AI to complete builds in months rather than years.Initially, BitGo Labs will focus on the intersection of AI and cryptocurrency. BitGo pointed out that the AI economy still requires cryptographic financial infrastructure to handle micropayments, achieve instant settlements, and ensure asset security. At the launch of the department, several related projects were introduced, including the consumer application Gokubu, which uses AI-driven card optimization for user spending and is now live, allowing users to be assigned personalized AI financial assistants to help them obtain better rewards and transaction value.BitGo stated that in addition to the initial projects, BitGo Labs will also release research reports, protocol prototypes, and reference implementations, and collaborate with developers, scholars, and institutions in the cryptocurrency and AI communities. BitGo CEO Mike Belshe previously stated in an interview that AI agents are likely to use stablecoins as their native currency, and human control over AI will last longer than some predict. This statement responded to Maelstrom Chief Investment Officer Arthur Hayes' view that digital currencies like stablecoins cannot serve as the native currency for AI agents because they cannot be directly converted into computing power.
