Aave

Aave has officially launched **Aave V4** on Ethereum mainnet, marking a significant upgrade to the decentralized lending protocol. The deployment introduces **Aave Pro**, a redesigned user interface available at [pro.aave.com](https://pro.aave.com/). This new interface provides users with an updated way to interact with the protocol's liquidity features. **Key Points:** - V4 represents the latest iteration of the open-source, non-custodial lending protocol - Aave Pro interface offers enhanced user experience for protocol interactions - Full details available in the [official announcement](https://aave.com/blog/aave-v4-live-ethereum) The launch follows a testnet phase that began in November 2025, allowing developers to preview and test the new features before mainnet deployment.

Aave V4 has completed nearly a year of comprehensive security reviews, totaling approximately 345 cumulative days of auditing. **Key Details:** - All security audit reports are now publicly available - Reports can be accessed at [github.com/aave/aave-v4/tree/main/audits](http://github.com/aave/aave-v4/tree/main/audits) - The protocol was built with a security-first approach from initial architecture through post-audit validation This extensive review period demonstrates Aave's commitment to protocol safety before the V4 launch. The team previously published a full transparency report detailing their layered security controls and comprehensive security program.

Aave has launched V4 after two years of research and development, introducing a completely new architecture designed to expand the protocol's capabilities. **Key Features:** - Supports more assets, market structures, and diverse risk profiles - Maintains the same Chainlink oracle infrastructure currently securing tens of billions on V3 - Enables expansion beyond onchain collateral, opening new DeFi lending use cases The upgrade represents a significant evolution for the lending protocol, moving from testnet deployment in January 2026 to mainnet launch.

Aave DAO has deployed a new market through a collaborative effort involving multiple protocol contributors. **Key participants:** - **@bgdlabs** handled the deployment - **@chaoslabs** and **@LlamaRisk** completed risk analysis - **@token_logic** provided additional support - **@chainlink** will supply price feeds for the market The deployment follows Aave's standard multi-party review process, with risk assessment teams evaluating the market before launch. Chainlink's oracle infrastructure will provide the pricing data needed for the market's operations. This marks the second similar deployment in recent months, following a February market launch with the same team configuration.

Aave V3 is expanding to X Layer, an EVM-compatible layer 2 network designed for scalable onchain transactions. **Initial Asset Lineup:** - USD, USDG, xBTC - OKB, xOKSOL, xETH - xBETH, GHO, xSOL X Layer connects to Ethereum's ecosystem while offering low-cost, high-speed transactions. The deployment aims to bring Aave's lending and borrowing capabilities to X Layer's growing user base.

A new audit contest is available on Sherlock's platform. Security researchers and auditors can participate in **Contest 1209** to identify vulnerabilities and earn rewards. - Contest accessible at [Sherlock platform](https://audits.sherlock.xyz/contests/1209) - Open for community participation - Part of ongoing security review process This follows previous contest activity, indicating continued focus on protocol security through community-driven auditing.

**Aave V4** has entered its **open security review phase** on Sherlock DeFi, marking a key milestone in the protocol's development. The review invites participation from: - Previous Aave auditors - Developers familiar with lending-pool mechanics - Security researchers interested in DeFi protocols This follows Aave Labs' September roadmap announcement, which outlined the final stages before V4's launch including public documentation, testnet deployment, and codebase release. The open review represents a **community-driven approach** to protocol security, allowing experienced auditors to contribute to one of DeFi's most significant upgrades.

**MetaMask's mUSD stablecoin** has been listed on Ethereum Core and Linea Build markets, expanding lending options for users. - Users can now **supply and borrow mUSD** on both platforms - This marks continued expansion for mUSD, the first stablecoin from a self-custodial wallet - Previously announced integration with Linea ecosystem for seamless on-ramps and swaps The listing provides new **DeFi lending opportunities** with MetaMask's native stablecoin across multiple networks.

**Aave has processed over $3.3 billion in liquidations** since launch to protect its lending protocol from bad debt. The DeFi protocol published a detailed blog post introducing **V4's new liquidation engine** and explaining improvements over the current V3 system. - Liquidations serve as a critical safety mechanism for lending markets - V4 aims to enhance the liquidation process with new technical improvements - The upgrade represents Aave's continued focus on protocol security Read the full technical breakdown: [Aave V4 Liquidations Blog](https://aave.com/blog/aave-v4-liquidations?utm_source=x&utm_medium=post&utm_campaign=liquidations)

**Aave V4 transforms DeFi lending** with a revolutionary architecture that unifies liquidity across markets. **Key Innovation: Hubs and Spokes** - Hubs store liquidity pools - Spokes implement custom lending rules and market logic - Multiple markets can draw from the same liquidity source **Benefits for Users and Builders:** - Enhanced capital efficiency across all markets - Specialized markets can access deep liquidity from day one - Custom lending parameters without liquidity fragmentation **Real-World Applications:** - Pendle markets accepting multiple PTs as collateral - Uniswap LP-focused lending markets - Shared ETH liquidity across different use cases **Strategic Impact:** V4 positions Aave as DeFi's operating system, enabling previously unviable markets while maintaining security and efficiency. This architecture supports the migration of global finance onchain by serving specialized needs without sacrificing liquidity depth.
