The release enhances post-mint value for creators and collectors by providing instant liquidity via Uniswap, creating a more efficient and liquid market for NFTs. It also features built-in secondary market rewards for creators. The default NFT mint fee has been lowered to 111 Sparks, equivalent to 0.000111 ETH. From the fee, 10% is allocated to a Uniswap liquidity pool for the NFT. The functionality is implemented through an extension of ERC-1155 called ERC20z. The standard allows NFTs to be wrapped into ERC-20 tokens or unwrapped back into ERC-1155 tokens, enabling seamless trading via Uniswap.Arbitrum Orbit Supports USDCArbitrum Orbit, a tech stack for deploying L2 and L3 chains, now supports bridged USDC as a custom gas token. USDC is also supported as a gas token option when deploying Orbit chains using rollup-as-a-service platforms AltLayer, Caldera, and Conduit. Arbitrum Orbit allows developers to build using WASM smart contracts, including in languages such as C++ and Rust. While chain developers can assign any ERC-20 token for gas payments, using USDC provides users with minimal price volatility, increased liquidity, and improved accessibility. Developers who use USDC for their chain’s gas token may also qualify for Circle’s USDC Grant Program, which offers up to $100,000 in funding.Polynomial Superchain Goes LivePolynomial Superchain, an OP Stack chain developed by the perpetual swaps exchange Polynomial Protocol, is now live and open for deposits. Users can participate in an Initial Liquidity Event by depositing and staking USDC, sDAI, and sUSDe. Users who have earned retroactive points can claim them by making a deposit to the chain. The liquidity raised from the event will support Polynomial Trade, the protocol's flagship perpetual futures exchange. The derivatives-focused rollup features a native liquidity layer, allowing applications to access shared network liquidity. Withdrawals for the network are not yet live.Candide Safe Recovery ModuleCandide Labs introduced a Social Recovery Module for Safe smart accounts, featuring ERC-4337 compatibility and support for gas payments via Paymasters. The module allows for multiple guardians, custom recovery periods, and the use of externally-owned accounts as guardians. Developers can integrate the module into their applications to enable users to set up account recovery during the account creation process.Other NewsBlock building researchGG21 goes liveBlockscout raises $3mRipple settles with SECFollow us on X, Lens, and Farcaster. ## Publication Information - [ETH Daily](https://ethdaily.io/): Publication homepage - [All Posts](https://ethdaily.io/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@ethdaily): Subscribe to updates - [Twitter](https://twitter.com/intent/follow?screen_name=ethdaily): Follow on Twitter
