Start experimenting with the new contracts and featured to build advanced protocols on Uniswap v4 🛠️. Audit reports:.• • GitHub 👇.

🔐 Security & Utility Enhancements. • IHookEvents Interface: Created new interface to standardize event emissions across all hooks. • CurrencySettler: Updated to use SafeERC20 for enhanced token transfer security. • BaseHook: Updated imports from v4-core for latest.

💰 Dynamic Fee Management Improvements. • BaseDynamicAfterFee: Added new transient storage functions for target amounts and apply flags, plus renamed _getTargetOutput to _getTargetUnspecified for exact input/output support. • Updated Fee Hooks: Updated BaseDynamicFee and.

💫 Enhanced BaseHook Functionality. • BaseAsyncSwap: New _calculateSwapFee function for asynchronous swap fee calculations. • BaseCustomCurve: New _getSwapFeeAmount function to calculate LP fee amounts.

⚡ New Hook: LiquidityPenaltyHook. Defend your pools against Just-In-Time (JIT) liquidity manipulation. Automatically penalize LP fee collection on recent liquidity additions and prevent JIT attackers from extracting value from your pool.

📊 New Hook: LimitOrderHook. Transform your liquidity pool into a sophisticated trading product. Let users place limit orders as out-of-range liquidity, then enable seamless order cancellation and automatic token withdrawal when orders fill.

🥪 New Hook: AntiSandwichHook. Protect your users from sandwich attacks by preventing swaps from executing at prices better than block start. Deploy this hook to guarantee fair trading and eliminate front-running exploitation in your pools.

hey @Uniswap v4 devs — OpenZeppelin Uniswap Hooks Contracts v1.1 is here 🦄. MEV protection, limit orders, Just-In-Time penalties, and a series of improvements to existing hooks deliver everything you need to build advanced Uniswap v4 pools. Here’s what’s new in this release 👇

Confidential smart contracts are coming to production 🔐. We're excited to partner with @zama_fhe to build privacy-preserving standards that bring financial institutions onchain. The first release is live — including a confidential ERC20 implementation:

Fresh paper by @exceed_silence: "Preemptive Provable Assertions" 📜. Explore how rollups can enable L2 transactions based on future state assertions while guaranteeing security. Thanks to @taikoxyz @NethermindEth and @fabric_ethereum for contributing.

Check out the new contracts, dive into the docs, and start building your vision ⚒️. Docs: GitHub👇

⚡Utils & Data Structures. The release comes with new utilities to improve the developer experience:. - Enhanced Arrays, Bytes with new utility functions.- EnumerableSet now supports StringSet & BytesSet.- EnumerableMap adds BytesToBytesMap.- EIP7702Utils for delegation checking.

🌉 Interoperability and L2s. Projects building on L2s can now leverage the new ERC20Bridgeable following ERC-7802 for seamless bridge compatibility. On the L1, builders can leverage EIP-2935 to access older block hashes by using the new Blockhashes library.

Need Social Recovery?. Pick an ERC-7913 multisig validator and an executor, and you're ready to go.

🏗 ERC-7579 modules. Developers can quickly ramp up on building custom ERC-7579 modules for their accounts by using experimental features such as composable validation and execution modules.

On the other hand, the first iterations for a Paymaster and PaymasterERC20 are now available as well 👀.
