According to The Defiant, the Kohaku Initiative under the Ethereum Foundation has released a software development kit (SDK) that supports direct integration of privacy protocols such as Railgun, Tornado Cash, and Privacy Pools into wallet interfaces without intermediaries.This SDK allows all privacy protocol transactions to be routed through the 4337 mempool, enabling users to control their privacy independently without relying on centralized relayers.The team has implemented private transactions with 4337 mempool relaying functionality, and integration with Tornado Cash and Privacy Pools is under development. Kohaku aims to make end-to-end privacy the default option for Ethereum users by abstracting the complexity of interacting with privacy protocols.Developers have created a CLI-based wallet demo, and wallets like Ambire are integrating it, while a browser extension wallet is also in development. Kohaku is also developing post-quantum accounts, multi-signature, and hardware wallet support.

WLFI officially releases the AgentPay SDK, an open-source, self-hosted AI Agent payment infrastructure built on USD1.According to the introduction, the AgentPay SDK supports AI Agents to hold, transfer, and use USD1 for payments on EVM chains; it adopts a self-hosted model where private keys are always stored on local devices, and data is not uploaded to the platform. It also introduces a strategy engine mechanism, requiring all transactions to be verified against preset rules before signing, and supports manual approval for transactions exceeding a threshold, with end-to-end encryption.In terms of functionality, the SDK is compatible with mainstream AI tools and Agent systems such as Claude Code, Codex, Cursor, Windsurf, Cline, Goose, and OpenClaw, and includes a Bitrefill plugin that supports direct purchases of gift cards, eSIMs, and prepaid cards. Additionally, the AgentPay SDK is open-source and uses the MIT license, with no platform fees.The content states that traditional stablecoins primarily serve the existing financial system, while USD1 focuses more on the next phase of currency application scenarios driven by AI Agents, positioning itself as the economic operational layer for autonomous AI systems.

XION recently published an article introducing its new infrastructure and application scenarios. XION announced the official launch of the DKIM module and the ZK module, becoming the first blockchain to directly store email authentication keys (DKIM) on-chain, as well as the first consumer-grade L1 public chain to implement zero-knowledge verification at the protocol level.XION pointed out that existing email verification solutions (including projects like zkEmail) rely on centralized DNS servers to obtain encryption keys. When email service providers rotate keys, the old verifications become invalid, and there are no historical records available. XION's DKIM module permanently stores these keys in the on-chain state, completely eliminating the reliance on centralized DNS infrastructure. Its ZK module implements zero-knowledge proof verification at the protocol level, achieving an efficiency that is 10 times that of smart contract solutions. The two work together, allowing users to prove any information in an email without exposing the email itself.XION stated that currently about 61% of employees who witness misconduct remain silent, as traditional options are often "anonymous but ignored" or "speak up but risk unemployment." With the above infrastructure, XION has realized various application scenarios, including:Anonymous reporting and workplace evaluations (proving employment status without exposing personal information)Wallet recovery without mnemonic phrases (using email as a backup key)Purchase behavior and certificate verification (without excessive sharing of personal information)Trust-based ticket resale and insurance claims, etc.It supports Gmail and Apple Mail from launch, covering approximately 3.8 billion email users globally (accounting for over 90% of the global email market). Currently, the XION platform has over 800,000 monthly active users, with more than 150 brands including Uber, Amazon, and BMW already onboarded. The official statement claims this is a verification infrastructure built for the existing internet, "capable of verifying anything while leaking zero information."
