Ethereum Launches zkAPI as Base Rolls Out Cobalt
The weekly roundup also spans USDT on Bitcoin, proposed shutdowns at Balancer and Blast, and Visa Direct's stablecoin settlement link.
Blast is an Ethereum Layer 2 (L2) scaling network distinguished by its native yield mechanism for ETH and stablecoins. Rather than holding user assets passively, Blast channels funds into Ethereum staking and Real-World Asset (RWA) protocols, automatically rebroadcasting the generated yield back to users at a base rate significantly higher than the zero percent default offered by most other L2s. Beyond user-facing yield, Blast introduces developer-oriented primitives designed to expand the design space for decentralized applications. Builders building on the network gain access to native yield flows and gas revenue sharing, tools that allow them to construct product experiences and business models not easily replicated elsewhere in the Layer 2 landscape. Categorized as a smart contract platform and Layer 2 network, Blast is backed by investors including Paradigm and eGirl Capital, and anchors its own growing ecosystem of applications. Its architecture positions it as both a settlement layer leveraging Ethereum's security and a yield-bearing environment for users and builders alike.

Users can still withdraw after Oct. 26, but they will need to use bridge contracts on Ethereum rather than Blast’s normal interface.
The shutdown exposes a hard limit for smaller layer-2 networks: infrastructure and security costs persist even when users and fee revenue leave.
Users face a staged move back to Ethereum, while the shutdown tests the economics of a Layer 2 built around native yield.
Users are being asked to move assets to Ethereum mainnet by October 26, though Blast says its L1 bridge contracts will remain available afterward.
Blast is the only Ethereum Layer 2 (L2) with native yield for ETH and stablecoins.
Blast (BLAST) is categorised as: Smart Contract Platform, Layer 2 (L2), eGirl Capital Portfolio.
The official Blast site is https://blast.io/.
