The post Aave V4 roadmap signals end of multichain sprawl appeared on BitcoinEthereumNews.com. Aave Labs has released its official launch roadmap for V4, laying out the final steps ahead of the major upgrade’s Q4 mainnet launch.  Alongside new architectural and security improvements, the roadmap introduces a fundamental shift in how user balances are tracked and highlights a strategic pullback from economically underperforming deployments across layer-2 and alternative layer-1 networks. The V4 release moves away from aTokens’ rebasing-style mechanics toward ERC-4626-style share accounting, a change that promises cleaner integrations, easier tax treatment, and better compatibility with downstream DeFi infrastructure.  In a recent technical development update, Aave Labs confirmed that “tokenization is to remain optional and built using ERC 4626 vaults,” and that internal accounting will eliminate the use of exchange rates or scaled balances. The goal is to “further improve the overall reliability of the protocol.” ERC-4626 is a widely adopted Ethereum standard that expresses user deposits as shares of a vault rather than balances that grow over time. In Aave V3, aTokens accrue interest by increasing a user’s balance directly — behavior that resembles rebasing tokens and often confuses integrations and portfolio accounting tools.  By contrast, ERC-4626 tracks yield through a rising price-per-share metric, leaving token balances unchanged. The result is more predictable behavior for integrators, auditors and tax software, as well as a clearer cost basis for users. The roadmap also outlines a series of release milestones, including a formal codebase publication, a public testnet launch with a redesigned interface, and the completion of a multi-layered security review involving formal verification and manual audits. Aave Labs said the roadmap reflects the protocol’s “final stages of review, testing, and deployment,” and that additional documentation and launch preparation materials will be released in the coming weeks. But the most pointed strategic shift comes not from the codebase, but from Aave’s own governance forums. “Aave…

The post Spain’s Civil Guard Arrests Leader of 260M Euro Crypto-Linked Alleged Ponzi Scheme appeared on BitcoinEthereumNews.com. Spanish authorities said they arrested a man accused of leading a 260 million-euro ($300 million) alleged international investment scam that promised returns on everything from cryptocurrency to gold and luxury yachts. The suspect, identified as A.R. and known online as “CryptoSpain,” allegedly ran the Madeira Invest Club, which began operations in early 2023 and marketed itself as a private investment group, the Ministry of Interior said. According to the ministry, the scheme attracted over 3,000 victims by offering guaranteed returns on contracts tied to digital art, luxury vehicles, whisky, real estate and cryptocurrencies. Promised profits and buyback guarantees were part of the pitch, but authorities say no real economic activity of investment took place. Instead, the club operated as a Ponzi scheme, where earlier participants were paid with funds from new investors, according to the ministry. As the operation expanded, the operation built a complex network of shell companies and bank accounts spanning at least 10 countries, including Portugal, the U.K., the U.S., Malaysia and Hong Kong. The investigation, known as Operation PONEI, involved Europol and law enforcement agencies from the U.S., Singapore, Malaysia, Thailand among others.
