Kaia: Merged Klaytn–Finschia EVM Layer‑1 for Developers

Kaia is an EVM-compatible Layer 1 blockchain formed in August 2024 by merging Klaytn (Kakao's chain) and Finschia (LINE's chain). Kaia uses BFT proof-of-stake consensus with ~1-second block times and immediate finality (no reorgs) and retains chain ID 8217. It exposes both the standard eth_* JSON-RPC namespace (recommended for Ethereum tooling) and the legacy klay_* namespace for Kaia-native features. A standout protocol feature is fee delegation, which lets a separate fee-payer account sponsor gas to enable gasless UX via Kaia-native transaction types built with the Kaia SDK. SwiftNodes provides a flat-rate Kaia RPC endpoint (HTTP + WebSocket) for developers to connect to the network.

• Kaia was formed in August 2024 by merging Klaytn and Finschia.
• Kaia mainnet uses chain ID 8217 (inherited from Klaytn).
• Consensus is BFT proof-of-stake with ~1-second block times and immediate finality (no reorgs).

WeChat and Alipay Gate AI Phone Agents in China

A recent analysis examines how China's AI phone ecosystem is controlled by super-apps like WeChat and Alipay, which decide whether AI assistants can operate within their apps. The article highlights Nubia's second-generation Doubao phone, powered by ByteDance's AI, which failed to complete tasks inside WeChat, Alipay, and other apps due to restrictions. Alibaba launched Qwen Intelligence for agentic smartphones, while the CAC added new on-device agents to its registry. Key insight: regulatory filings do not grant app access; super-apps like Alipay and WeChat open their services but not their screens, positioning themselves as gatekeepers. The article notes that deals so far turn AI phones into switchboards, with the assistant interpreting requests and the app controlling service execution and payment.

• Nubia began selling its second-generation Doubao phone on September 16, 2026, with ByteDance's AI assistant, which failed to complete tasks in WeChat and other apps.
• Alibaba launched Qwen Intelligence on September 22, 2026, to power agentic smartphones.
• The Cyberspace Administration of China (CAC) registered three new on-device phone agents on September 22, 2026, from Honor, Xiaomi, and StepFun.

China's AI Shopping-Agent War Shows Europe the Future

This analysis compares conflicts between AI shopping agents and e-commerce platforms in China and the US, and draws implications for Europe. In China, ByteDance's Doubao agent was initially blocked by Taobao and WeChat, but later integrated through negotiations and a formal access protocol (SAEP). In the US, Amazon blocked Meta's Muse agent, which then partnered with Shopify. The article argues that AI agents will shift advertising from selling attention to charging for outcomes, such as commissions and access fees, potentially benefiting platforms like Meta. It advises European retailers to make their product data agent-readable and predicts that Europe will rely on regulation, transparency, and data protection rules rather than commercial deals or super-app control. Ting Wasner-Lian, founder of SE Incubator Consulting in Vienna, offers strategic insights for European decision-makers.

• In December 2025, ByteDance launched its first AI phone with Doubao AI agent, which was promptly blocked by Taobao, WeChat, and several banking apps.
• From January 2026, ByteDance integrated third-party ride-hailing, food delivery, and ticketing services into Doubao, and in September introduced a formal access protocol called SAEP.
• On September 21, 2026, Amazon blocked Meta's AI shopping agent Muse; Meta then partnered with Shopify to allow purchases on its merchant network.

TikTok Minis: Developer Technical Overview

The document is a technical overview for developers integrating with TikTok Minis. It describes TikTok Minis as web apps that run inside the TikTok client WebView and interact with client capabilities (login, authorization, payment, ads, subscriptions) via a JavaScript SDK exposed as window.TTMinis. Pages are standard Web projects (HTML entry + JS bundle) and developers use a CLI toolchain (minis init / minis dev / minis build / minis config) for local debugging, build verification, packaging and upload. The overview contrasts TikTok Minis with traditional WeChat/Douyin mini apps (different page models, debugging, and build delivery) and recommends treating Minis as Web apps plus a client JSAPI layer, with coordinated frontend, backend, and client integration for production features and monetization.

• TikTok Minis run as Web apps inside the TikTok client WebView rather than a proprietary mini-app runtime.
• Client JSAPIs are exposed via window.TTMinis and initialization requires TTMinis.init({ clientKey }) in the HTML head.
• A CLI toolchain supports development and packaging: minis init, minis dev, minis build, and minis config.
