self-hosted

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.

According to Forbes, Cloudflare announced the acquisition of the JavaScript/TypeScript runtime company Deno. Deno's founder Ryan Dahl (the inventor of Node.js) and co-founder Bert Belder will lead the entire team to join Cloudflare.The core asset of this acquisition is the open-source project celld------a distributed deployment tool that runs Workers and Durable Objects with a single Rust binary file, allowing enterprises to run Cloudflare's serverless programming model on their own infrastructure, fundamentally addressing the long-criticized "lock-in" issue of the Workers platform. Cloudflare plans to merge celld into the open-source runtime workerd to achieve complete self-hosted support.Deno has previously raised $26 million, and the financial terms have not been disclosed. Deno Deploy will shut down in six months, and the Deno runtime will stop development after one year of security updates. This is the second acquisition of developer tools completed by Cloudflare within four months, having previously acquired the company behind the Vite build tool, VoidZero, in June of this year.

On September 8, the ZKsync development team Matter Labs announced that it has open-sourced the permission engine of its privacy blockchain platform Prividium for financial institutions under the Apache 2 license. This engine is responsible for managing roles and access permissions on the chain, determining who can read and write data. After the open-sourcing, institutions can run the permissioned chain in their own environment based on the public code without signing commercial agreements, and can independently inspect, run, and modify the core code, reducing reliance on a single vendor.The Deutsche Bundesbank became the first institution to test and deploy the open-source permission engine in its own infrastructure. Matter Labs stated that both parties will continue to collaborate on platform design and testing. Prividium achieves privacy by keeping transaction data within the institution, only recording zero-knowledge proofs that the ledger has been correctly updated on Ethereum or other compatible chains. Previously, the core of ZKsync OS, Atlas sequencer, Airbender prover, interoperability contracts, and block explorer and monitoring components have been open-sourced.Matter Labs CEO Alex Gluchowski stated that feedback from regulators indicated that relying solely on commercialized core components leads to unacceptable single vendor dependency, and the ability to run, inspect, and modify the code independently is a prerequisite for adoption. He also pointed out that this open-sourcing does not change the role of the ZK token, only adjusting which parts of the Prividium software are public code and which remain commercial products. Connectors such as management consoles, user access tools, and core banking system integrations remain paid products.

According to official news, Tether has launched a developer grant program that will reward developers with USDT or Bitcoin for building localized AI and payment infrastructure. There is no total grant cap for this program, and rewards will be issued based on technical tasks and deliverables, with current individual bonuses ranging from $1,500 to $4,000.This funding focuses on Tether's open-source technology stack, including wallet infrastructure, browser extensions, e-commerce integration, and particularly supports its local AI platform QVAC. Tether stated that QVAC can run AI inference directly on the device locally, without relying on cloud servers, to reduce latency, costs, and data exposure risks.In addition, Tether will also promote the development of its Wallet Development Kit (WDK) ecosystem. This tool allows developers to directly embed self-custody wallets within applications, enabling local key generation, transaction signing, and asset transfers without relying on custodial services or third-party APIs.Tether CEO Paolo Ardoino stated that a significant amount of infrastructure still forces developers to rely on centralized platforms and data business models, and Tether hopes to fund systems that can "run locally, hold value directly, and have no external dependencies" to enter the market.

The founder of Binance, CZ, responded to early Bitcoin investor Davinci Jeremie regarding the "zero balance" experience of his multi-signature wallet, stating that if a wallet software upgrade changes the derivation path, it is "very bad and scary," referring to it as "self custody perks."Previously, Davinci pointed out that his 2-of-3 multi-signature wallet was unable to find the original address and balance despite using the correct private key due to a software change in the derivation path, and he ultimately relied on the saved old path to recover it. Several industry participants added that different standards (such as BIP44, BIP84, BIP86) can generate different addresses under the same mnemonic phrase, and if a wallet upgrade is not adequately prompted and migrated, it could lead to users misjudging the risk of asset loss.
