hook

Uniswap has confirmed that it will support V4 Hooks functionality on the Hyperliquid L2 project Elysium, allowing developers to build customizable liquidity pools that support dynamic fees and custom trading logic using V4 Hooks. The Elysium mainnet is expected to officially launch on November 9.

Uniswap posted on platform X that the Permissioned Pools Hook is a new standard that introduces permitted assets into automated market makers (AMM) and performs compliance checks at the protocol level.

The official account of the token launch platform Ignition on Robinhood Chain stated that the team provided an explanation after being silent for about a week. On October 23, a team member with access to the developer wallet (0x7d17...69B9) transferred 15 million IGNITION from that wallet to a new wallet without the consent of the other members and sold it seconds later. The proceeds were sent to their personal wallet, which had previously been receiving their share of creator fees. The official statement indicated that this person no longer agrees with the project's direction and is no longer part of the project.The official statement mentioned that the creator fee permissions have been transferred to a new wallet that is solely controlled by the existing team. The launch platform is still operational, the Hook Layer testnet continues to run, and the Hook Pad for developers remains open. Future plans include transferring creator fees to a multi-signature wallet controlled by the team to prevent a single person from transferring again; publicly disclosing the fee, treasury, and team wallet lists; advancing the Hook Layer mainnet; and resuming weekly updates. The official also stated that related operations had previously been visible on-chain and will be explained by the team in advance.According to the project's official website, Ignition is a token launch platform deployed on Robinhood Chain, with issued tokens being ERC20 with a fixed supply, trading in the Uniswap v4 pool since the initial block. Hook Layer is its proprietary chain built on Robinhood Chain, with gas fees paid in IGNITION, and developers can configure hook modules for tokens through Hook Pad.

Uniswap Labs announced that Aggregator Hooks are now live, enabling aggregation functionality in Uniswap v4. This mechanism wraps external liquidity sources into v4 pools through Hooks, allowing any routing to treat them as Uniswap pools. It is currently available on the Uniswap web interface and API, covering Ethereum mainnet, Base, and Robinhood Chain, with more networks to be integrated soon.On the first day of launch, it supports seven external sources, including Curve, Fluid, and PancakeSwap. Each block routing will pull the latest quotes from the integrated sources, constructing the optimal path between the Uniswap pool and external sources during exchanges, and completing settlements within a single transaction without the need for additional authorization. Uniswap stated that most on-chain liquidity is already on Uniswap, but new liquidity may still appear in other places. After external sources are incorporated into v4, exchanges routed through them will incur protocol fees, contributing to UNI burn.

The decentralized trading protocol Uniswap announced that the VolatilePair Hook has been launched on the Ethereum mainnet, with the first trading pair being ETH/USDC. This is a dynamic fee Hook for liquidity providers in Uniswap v4, where fees adjust according to market fluctuations.Uniswap stated that this year, the trading volume of volatile trading pairs on Uniswap exceeded $50 billion. Unlike stablecoin trading pairs, these assets do not have a fixed price, and liquidity providers under static fees will bear the price changes not covered by the fees. This Hook recalculates the buy and sell rates separately for each exchange based on recent price changes, maintaining competitive spreads.When the pool price rises, the buying cost is higher and the selling cost is lower; when the price falls, the direction of the fees is reversed. After significant price changes, trades that drive price retractions will pay temporary fees. Pool parameters and fee logic can be upgraded through Uniswap governance without the need to migrate liquidity pools. The StablePair Hook, launched in September, introduced dynamic fees for stablecoin trading pairs, achieving a trading volume of $3.1 billion within four weeks. The VolatilePair Hook is part of the Hooks launched by Uniswap Labs, along with StablePair, Permissioned Pools, and LitePSM.

According to GMGN data, the market capitalization of Robinhood ecosystem HOOKR briefly surpassed 30 million USD, currently reported at 28.3 million USD, with a 24H increase of over 35%. It is reported that HOOKR is the project token of the programmable market Launchpad Hookr.fun on the Robinhood Chain.Hookr.fun is built on Uniswap v4 Hooks, allowing users to issue tokens and combine custom trading rules such as Anti-Snipe, dynamic fees, automatic burn, LP rewards, and Nth-buy Pot, while establishing the Hook market. Other projects can pay fees to its developers when using related Hooks. In addition, the platform supports trading pairs with ETH or HOOKR as new tokens, where part of the ETH trading fees can be used to buy back and burn HOOKR, forming a token mechanism linked to the platform's trading activities.According to market news, HOOKR's price is highly volatile and easily influenced by the popularity of the Robinhood Chain ecosystem and market sentiment, please be aware of trading risks.

According to the official announcement, Gate has launched HOOKED, HOOKR contract trading, trading robots, and Order Tracking features, with both contracts supporting 1-10 times leverage.HOOKED (Hooked) is a MEME Launchpad that supports programmable trading rules; HOOKR (Hookr.fun) is a functional Token of the programmable token issuance market protocol Hookr.fun on the Robinhood Chain.

According to GMGN data, the market capitalization of the Solana-based meme coin HOOKED once surpassed 17 million USD, currently reported at approximately 13.96 million USD, with a 24H increase of over 110%. It is reported that HOOKED is the token of the Hooked platform, a meme launch platform within the Solana ecosystem.Hooked integrates Transfer Hook, which supports setting holding, trading, and transfer restrictions for tokens through on-chain rules to reduce issues such as bot sniping, concentrated holdings, and malicious sell-offs. The prices of meme coins are highly volatile and easily influenced by market sentiment and trending events; please be aware of trading risks.

Decentralized Trading Infrastructure 0x stated that this year it has routed 81.92 million transactions with a trading volume of 4.267 billion USD, with approximately 70% touching Uniswap liquidity. 0x indicated that there has been an increase in malicious Uniswap v4 hooks recently, which provide one price in quote requests and another price at settlement, profiting from users by deceiving aggregators, wallets, and trading applications.After analyzing 84,163 hooks across 6 chains, 0x reported that only 19.4% are safe, 54.2% are malicious, and 26.4% may be malicious. Transactions routed through malicious v4 hooks can result in actual amounts received being up to 50% less than the quoted price. The article cites examples where the Base chain ETH/NVDAc pool hooks have accumulated fees of approximately 143,000 USD, and the BNB chain USDT/WBNB pool hooks have accumulated about 18,600 USD.0x stated that routing parties must ensure that the quoted amounts in pools are consistent with actual execution behavior, applications must have the capability to quickly eliminate suspicious routes, and users should be aware that optimal quotes are only useful when the route is safe. 0x has implemented measures such as detection and pool audits to prevent such pools from appearing in routing.

According to The Block, Uniswap Labs announced the launch of a new tool, StablePair Hook, designed specifically for stablecoin trading pairs such as USDC/USDT and USDC/USDG.Uniswap Labs stated that StablePair Hook can provide traders with consistent and predictable quotes, allowing liquidity providers to retain more of the value they create. Data shows that in the second quarter, the trading volume of exchanges between stablecoins on Uniswap reached $43.4 billion, surpassing the total of the other three major on-chain trading venues.StablePair Hook replaces fixed rates with dynamic rates, which adjust based on the degree of price deviation from the reference price within the pool. When the price is close to the reference price, the Hook adjusts the transaction fee for each trade to maintain a fixed bid-ask spread; when the price deviates from the reference range, trades that push the price away incur no fees, while trades that pull the price back to the reference price use a Dutch auction mechanism, with fees decreasing block by block from high to low until accepted by the trader. Uniswap Labs stated that this allows liquidity providers to retain more value from price returns.The first batch of StablePair Hook pools will go live on Ethereum, supporting USDC/USDG and USDC/USDT trading pairs. This Hook can be upgraded through Uniswap governance, and the fee system and other parameters can be adjusted without migrating liquidity.

Uniswap announces the official launch of DualPool Hook. DualPool is an open-source Uniswap v4 Hook, jointly designed and developed by Spark and Uniswap Labs, allowing market makers to earn yields by depositing idle assets into lending protocols during the waiting period for liquidity funds to be executed, and to withdraw funds back to the liquidity pool when a transaction occurs.From an external perspective, DualPool is indistinguishable from a regular Uniswap v4 liquidity pool, and traders, aggregators, and solvers still complete transactions through the Pool Manager. Its internal mechanism is that liquidity funds are stored in an ERC-4626 yield vault and are automatically withdrawn when a transaction needs to be executed, deployed to concentrated liquidity positions, thereby ensuring transaction execution while allowing idle funds to continuously generate lending yields.

According to research by OpenSourceMalware, the North Korean hacker group Lazarus has adopted new techniques in malicious activities targeting developers, such as "infectious interviews" and "TaskJacker," hiding the second-stage loader in the pre-commit scripts of Git Hooks. "Infectious interviews" is a series of attack activities where the organization lures developers into cloning malicious code repositories by faking recruitment processes in the cryptocurrency/DeFi field, ultimately stealing crypto assets and credentials.Researchers recommend that developers who are asked to clone code repositories as part of the interview process should be wary of such risks and preferably run in an isolated environment to avoid mounting personal browser configurations, SSH keys, and cryptocurrency wallets.
