Odaily News The Web3 social protocol Lens Protocol officially released its V2 version during the Ethereum Paris EthCC conference. It aims to provide openness, composability, profit sharing, trust, and security. Users can now directly execute external smart contract operations within Lens publications, and the ability to interact with smart contracts within social media has been added to Lens V2. Added third-party contract operation permissions, including whitelist functionality, minting NFTs on Sound.xyz (Ethereum mainnet), and minting NFTs on Opensea (Polygon). Added asset management functionality, including delegating operations to any wallet, allowing users to perform operations using other wallets, not just a single wallet. Users can store their profiles directly on a hardware wallet and use them on another wallet. The new version supports storing DAO or community profiles on a multi-signature wallet and allows them to be accessed from one or more addresses. This ensures the security and access control of personal profiles and allows multiple addresses to be associated with them. In addition, V2 provides support between configuration files and ERC-6551; LIP-4 introduces Profile Guardians to enhance the security of personal profiles.

Odaily News: Patrick Hansen, Director of Strategy and Policy at Circle EU, expressed optimism about the future of Euro-denominated stablecoins at the EthCC conference in Paris. While the US dollar may maintain its first-mover advantage, Euro stablecoins are expected to see increasing real-world use cases, surpassing their current meager market share. Currently, Euro-denominated tokens account for only 0.3% of the stablecoin market, with a value of $300 million. In contrast, the Euro holds a 20% share in the traditional currency system. Furthermore, Hansen mentioned the shift in the entire cryptocurrency capital market from speculation to utility. The growing usage of stablecoins in remittances, B2B transactions, and other scenarios demonstrates this trend. Users will prefer stablecoins denominated in local currencies for these purposes. Integrating Euro stablecoins into existing European payment systems will also facilitate their adoption. (Cointelegraph)

Odaily News: Charles d'Haussy, CEO of dYdX Foundation, stated during the EthCC conference held in Paris, France, that he does not consider centralized exchanges as competitors to dYdX. He predicts that centralized exchanges will become the gateway to DeFi. The dYdX protocol recently launched its latest version, v4, on the public testnet. Charles mentioned that one can imagine a world where a centralized entity with KYC and customer risk profiles provides spot trading, and perhaps they could offer a better user experience than DeFi with simpler integrations, connecting to DeFi from centralized exchanges.

Odaily News: Ethereum Founder Vitalik Buterin recently gave a presentation at the Ethereum Community Conference (EthCC), where he discussed in detail the account abstraction upgrade called "paymasters." This upgrade allows users to pay gas fees using tokens for transactions, aiming to attract billions of people to use Ethereum. Account abstraction enables users to switch from externally owned wallets (EOAs) to smart contract-based wallets. If successful, this upgrade will make wallet management more efficient and seamless. Vitalik Buterin and the community believe that this can lead to wide adoption of cryptocurrencies. Furthermore, the cryptocurrency industry is plagued by users losing their mnemonic phrases or having them stolen. With account abstraction, users can create non-custodial wallets that act as programmable smart contracts. Wallet recovery is just one of the many features that this new upgrade brings. (Coinedition)
