Gwei Name Service (GNS) launched an ownerless, unruggable Ethereum Name Service (ENS) alternative built as a fork of the wei.domains protocol. Forked from developer z0r0z's wei-names codebase, the new service, gwei.domains, removes all administrative controls and administrative ownership structures. The deployment eliminates the Ownable contract, removing the contract owner, admin-only configurations, and the ability to alter fees or withdraw funds.
Registration fees are fixed as constants in the contract, and because no withdraw function exists, all collected ether is locked in the contract forever Registrations start at under one dollar (at current ETH prices) for non-premium domains, while subdomains under the .id.gwei namespace are offered for free.
OP Labs introduced a new framework called the L2ContractManager, enabling OP Stack chains to automatically upgrade their Layer 2 predeploy contracts during hardforks without needing manual multisig transactions. Predeploys are Solidity smart contracts included in the L2 genesis state, such as L1Block and 26 other active proxies, that have historically been difficult to upgrade due to the operational complexity of coordinating multisig signs across numerous network instances. The new system uses Network Upgrade Transactions (NUTs) injected directly at the hardfork activation block.
Spark launched the Stablecoin FX Layer, a shared liquidity infrastructure built on Uniswap v4 that allows stablecoins to access shared liquidity. The FX layer is launching with approximately $150 million of liquidity across USDS/PYUSD and USDS/USDT stablecoin pools, with USDS serving as the primary quoting and settlement asset. The system coordinates capital using the DualPool hook within Spark's wider Shared Liquidity Layer (SLL).
Governed by allocation frameworks defined by Spark, the hook enables programmable inventory management by allowing idle stablecoin assets to support other ecosystem strategies or return yield. The moment capital is demanded for swap execution, the hook automatically recalls and deploys it back to the active Uniswap pools. The solution aims to address the growing fragmentation amid multiple issuers. Rather than requiring individual issuers like PayPal or Ripple to bootstrap depth across multiple venues, the shared infrastructure lets networks route transactions through a unified, oracle-free liquidity layer managed at the protocol level.
