Ethereum Launches zkAPI, Base Rolls Out Cobalt, Balancer and Blast to Shut Down

The latest weekly project update report, published by Wu Blockchain on October 3, highlights several protocol changes, including Ethereum’s zkAPI launch, Base’s Cobalt upgrade, and shutdown decisions for Balancer and Blast. The update also touches on stablecoin activity linked to Bitcoin, making the report useful for tracking both infrastructure and liquidity shifts.

Ethereum zkAPI and Base’s Cobalt upgrade

Ethereum’s zkAPI is positioned as a developer-facing step toward more accessible zero-knowledge tooling. Rather than forcing teams to build custom circuit interfaces, the API offers a more standardized layer for proof-related workflows. Base’s Cobalt upgrade, meanwhile, is being framed as a network performance and tooling update, although node operators should watch official release notes for rollout specifics. The report’s focus on infrastructure mirrors Bitcoin’s own experiment with stablecoin expansion, as in Tether-Backed Utexo to Launch USDT on Bitcoin This Month.

Neither Ethereum nor Base has framed these changes as emergency fixes, but they arrive during a period of active chain-level iteration. At the same time, trading venues are reassessing Bitcoin-linked pairs, as shown by Upbit to List POD Trading Pairs Against KRW, BTC and USDT.

Balancer and Blast shutdowns reshape on-chain options

On the shutdown side, Balancer and Blast are moving toward winding down or consolidating parts of their operations, according to the weekly update. These decisions matter because users and integrators often need to unwind positions, migrate liquidity, or update contract references before a final deadline. Even in periods of broader market stability, protocol shutdowns create operational risk if they are ignored. Bitcoin’s longer-term protocol work continues on a separate path, as explored in Bitcoin’s Post-Quantum Roadmap Takes Shape Around P2MR and SHRINCS. Protocol teams have not all published identical timelines, so checking each project’s official notice remains important.

Listing and liquidity decisions are being reassessed alongside those closures. One sign is the continued expansion of Bitcoin and stablecoin trading options on major platforms, which signals that exchange-side demand is not uniformly retreating.

What to watch in the coming weeks

For node operators and protocol users, the key task is to track official migration windows and release notes rather than rely on secondary summaries. Upgrades like zkAPI and Cobalt may eventually improve tooling, but shutdowns like Balancer and Blast require direct action.

The common thread across these announcements is that network changes are becoming more frequent and more operationally consequential. Users who treat each announcement as a formal migration event, rather than a background update, will be better positioned as the next wave of protocol rollouts arrives.
