v4

According to official news, Uniswap has launched Permissioned Pools, a new hook standard in Uniswap v4 that supports permissioned asset trading through automated market makers (AMM), with compliance enforced directly on-chain. Permissioned asset pools are collaboratively built by on-chain asset management teams. The first batch of partners includes Superstate, Securitize, and Dowgo.

The Robinhood Chain token launch platform Pons will release version 2, planning to introduce multiple feature updates. It is reported that Pons v2 will introduce a Bonding Curve mechanism priced in ETH, remove trading restrictions for non-developer wallets, and support custom trading pairs, including RWA assets such as USDG, NVDA, AAPL, and HOOD.In addition, Pons will adopt a redesigned fee structure using Uniswap V4 pools and Hook, with creators defaulting to receive fees in ETH; when the token value reaches 4.2 ETH, it will automatically graduate to a permanently locked full-range position on Uniswap V4. Other updates include the addition of a CTO feature with a 3-day time lock, support for collecting fees in stablecoins or other tokens, and the introduction of an optional tax mechanism for each buy and sell transaction.

TRON recently officially released GreatVoyage-v4.8.2 (Pyrrho). The new version further enhances compatibility with Ethereum Pectra and the Osaka upgrade, adds CLZ instructions, secp256r1 signature verification precompilation, and migrates fastjson to Jackson, while unifying node monitoring metrics from InfluxDB to Prometheus.This upgrade further strengthens TRON's capabilities in smart contract compatibility, interface processing, node monitoring, and operational management. The official reminder states that this version is a mandatory upgrade, and node operators must complete the update by August 16, 2026, 23:59 (Singapore time) to avoid affecting block synchronization. The Event Plugin is also upgraded to v3.0; nodes using the official plugin must upgrade the plugin first before updating the node version; nodes using self-developed plugins should also complete adaptation as soon as possible.

According to PConline Pacific Technology reports, the official version of DeepSeek-V4 has begun a small-scale gray testing, including two versions: DeepSeek-V4-Pro and DeepSeek-V4-Flash. Insiders say that the official version is expected to be released at the end of this month, which is somewhat delayed compared to previous plans. The new version will focus on optimizing inference efficiency, response speed, and agent capabilities.Developers participating in the testing claim that V4's comprehensive capabilities are on par with Anthropic Opus 4.8, with code generation close to OpenAI GPT-5.6 Sol, and improvements in scenarios such as 3D modeling, SVG image generation, and mini-game development. DeepSeek-V4 has completed the adaptation for de-CUDA, and on the first day of launch, it will be compatible with multiple domestic AI chips, and will adopt peak and off-peak API billing, with peak prices being double that of off-peak.

Aave V4 has been deployed to the Avalanche network, marking the first multi-chain deployment of the Aave V4 Hub & Spoke architecture. This deployment includes a core liquidity hub and three sub-markets: the main market supports lending of assets such as WAVAX, BTC.b, USDC, USDT, and WETH.e; the AVAX-related market focuses on AVAX liquidity staking strategies, allowing users to deposit sAVAX with a 95% collateral rate and borrow WAVAX; the foreign exchange market supports mutual collateralization and lending among three stablecoins: EURC, USDC, and USDT.The core liquidity hub adopts a shared liquidity pool design, with all sub-markets sharing the same pool to avoid liquidity fragmentation. Aave stated that since its deployment on Avalanche in 2021, the historical cumulative inflow for V2 and V3 has exceeded $15 billion, and the current stablecoin utilization rate in the V3 market is over 90%.

According to official news, Uniswap Labs has released a temperature check proposal, suggesting the activation of protocol fees in the v4 pool. This proposal follows the rapid governance process previously approved by UNIfication and will directly enter a five-day Snapshot voting period, followed by on-chain voting.Due to the Hook architecture of v4 making fee settings more complex than v2/v3, the proposal has designed the V4 Fee Controller system, which includes two core contracts: V4FeePolicy calculates the fees for any pool based on governance rules, and V4FeeAdapter is responsible for executing governance overrides and collecting fees into TokenJar. Fees are calculated hierarchically based on the family of the pool: first checking the specific trading pair rate set by governance, then the family default rate, and finally the global default rate.This proposal aims to activate fees for three types of pool families across 11 chains including Ethereum, Arbitrum, Base, and BNB Chain: static rate pools without Hooks, CCA pools after continuous liquidation auctions, and aggregator Hook pools. The rates for aggregator Hook pools are adjusted by a 25x multiplier, with a default of 10 bp for non-Base chains (3 bp for stablecoin pairs) and a default of 3 bp for Base chains (1 bp for stablecoin pairs). All fees will flow into each chain's TokenJar, and the amount of UNI burned on L2 and Alt-L1 will be cross-chain bridged to the Ethereum mainnet and sent to the 0xdead address.The Snapshot voting window is from July 7 to July 12, and on-chain voting will start during the week of July 13. Since GovernorBravo limits each proposal to 10 actions, two on-chain votes will be submitted in parallel to cover all chains.

According to The Block, the decentralized lending protocol Aave saw its deposit scale surpass $100 million about two days after launching the V3 market on the Monad network. Aave deployed the V3 version on July 3, introducing lending functions and the GHO stablecoin to the network for the first time, initially supporting 12 assets including USDT 0, USDC, GHO, WETH, and cbBTC. Within 24 hours of launch, the deposit scale had already exceeded $75 million.According to the Aave governance proposal, the Monad Foundation has committed to providing $15 million in incentives over the next 12 months and to purchase and hold 10 million GHO for at least 6 months; the Aave DAO will also provide an additional 500,000 GHO to support the development of the stablecoin ecosystem.In addition, Aave founder Stani Kulechov stated that the deposit scale of Aave V4 on the Ethereum mainnet has also surpassed $250 million, setting a historical high for this version. He expressed hope that the future deposit scale of V4 will further grow to $1 billion and continue to expand into crypto asset collateralized loans and securities-backed lending businesses.

The TRON Nile testnet has recently launched a quantum-resistant upgrade and released the mandatory upgrade version GreatVoyage-v4.8.2-PQ1-build1. This version introduces post-quantum signature capabilities for the first time, supporting two signature algorithms: Falcon-512 and ML-DSA-44, further advancing TRON's technological exploration and capability verification in the direction of quantum resistance.According to the official introduction, the aforementioned capabilities can be applied in scenarios such as transaction signing, SR block signing, P2P relay node handshakes, and TVM contract verification. TRON reminds developers who have deployed nodes on the Nile testnet to complete the version upgrade as soon as possible. Meanwhile, the related new features will only take effect on the Nile testnet after being approved through proposal voting; the activation of testnet functions does not mean that the mainnet will go live simultaneously.

Aave founder Stani Kulechov stated that Aave V4 can be used to reconstruct the on-chain securities financing market. He mentioned that securities financing is one of the largest markets on Wall Street but receives relatively little attention from the outside. Securities collateralized loans have become a multi-trillion dollar business, with the U.S. repurchase market having an average daily exposure of about $12.6 trillion, secured financing reaching $1.3 trillion, wealth management securities collateralized loans exceeding $400 billion, and approximately $4.6 trillion in assets in the securities lending market being lent out, generating a record $15 billion in revenue by 2025.Aave V4, through a "liquidity hub + modular market" structure, allows for shared liquidity at the underlying level while setting up segmented markets with different risk parameters, asset ranges, and rules at the upper level. Aave V4 can support three core securities financing scenarios: securities collateralized loans, repurchase transactions, and securities lending. Tokenized securities can be used as collateral to borrow GHO or stablecoins; repurchase transactions can borrow stablecoins using tokenized securities as collateral and achieve atomic settlement; in securities lending, the tokenized securities themselves can become borrowable assets, with lending income flowing directly to asset holders.Stani indicated that Aave V4 could adopt a single shared liquidity hub or split multiple hubs by asset class and risk. The former has deeper liquidity, while the latter offers stronger risk isolation. He believes that the realistic path may start with unified liquidity and, as the types of collateral expand, gradually evolve into a multi-hub structure categorized by asset class and risk.

The founder of the decentralized lending protocol Aave, Stani, posted on the X platform stating that the "Spokes" mechanism in Aave V4 will become a key architecture for the protocol's expansion, enabling quick access to diverse lending and financial scenarios.

According to CoinDesk, in April this year, the cross-chain bridge KelpDAO based on LayerZero suffered an attack of $292 million, triggering a deposit run of up to $8.45 billion in the DeFi lending protocol Aave within 48 hours. In response to external doubts about the protocol's risk control capabilities, Aave founder and CEO Stani Kulechov stated that this incident precisely proves Aave's "resilience."Kulechov stated at the Proof of Talk conference in Paris that Aave V3 has withstood multiple market cycles and remains stable even in extreme market conditions. He believes that recent DeFi security incidents mainly stem from third-party infrastructure rather than vulnerabilities in the protocol's own smart contracts.However, according to risk analysis firm LlamaRisk, the attacker exploited a vulnerability in KelpDAO to mint worthless collateral and deposited it into Aave, subsequently withdrawing real wETH, resulting in approximately $123.7 million in bad debt for Aave V3. To address the crisis, Aave DAO urgently allocated 25,000 ETH, and Kulechov personally injected an additional 5,000 ETH, with a total rescue scale of about $300 million.In response to the exposed systemic risks, Aave is planning to restructure its risk management framework through the V4 upgrade. The new version will adopt a modular "Hub-and-Spoke" design, replacing the traditional liquidity pool model, allowing the protocol to implement independent risk pricing for different collateral types and freeze specific collateral assets before risk spreads, thereby reducing the likelihood of chain reactions triggered by cross-chain bridge failures.

Babylon Labs has initiated a temperature check proposal in the Aave community, proposing to integrate native Bitcoin as collateral on Aave V4 through the Babylon Trustless Bitcoin Vaults protocol.This solution does not require wrapping, cross-chain bridges, or custodians. Users will lock Bitcoin in Taproot UTXOs, and redemptions will be controlled by on-chain rules (such as loan repayments), settling directly to Bitcoin UTXOs. The proposal deploys two Aave V4 Spokes: Babylon Core Lending Spoke (lending) and BTC Vault Swap Spoke (post-liquidation settlement).Collateral exists in the form of vaultBTC, a transfer-restricted ERC-20 token that can only be transferred between fixed whitelisted addresses. In the liquidation process, liquidators can immediately settle with WBTC, and subsequent Bitcoin redemptions will be completed by arbitrageurs.

According to a message posted by Aave founder Stani Kulechov on X, Aave V4 is being gradually launched in phases, introducing a brand new dual-layer isolation market architecture. This architecture separates collateral into independent Hubs, with each Hub further divided into Spokes, implementing selective cap control for liquidity sharing between the Spokes within each Hub.The initial market structure is organized around three Hubs: Prime, Core, and Plus, with more Hubs expected to be launched in subsequent phases. This architecture achieves more refined collateral isolation and liquidity supply management compared to Aave's previous market design. The phased launch allows Aave to progressively deploy V4 while continuously monitoring performance and risk parameters under the new market structure before a full launch.

Aave officially announced an update to its bug bounty program to better match the risk characteristics of various parts of the ecosystem and simplify the review process. According to the latest adjustments, the bounty cap for critical bugs in Aave V4 and Core Aave V3 has been increased to five times the original amount.Aave Labs also proposed a reorganization of the bounty framework, placing different subsystems under the management of platforms such as Immunefi, Sherlock, and Cantina. The core components such as Core Aave V3, V2, and GHO will continue to be managed by Immunefi; Aave V4 and Aave App Stack will transition to Sherlock; and Aave V3 on Aptos will be managed by Cantina.

Aave DAO has initiated a governance proposal to establish a dedicated Bitcoin Spoke driven by the Babylon protocol in Aave V4, allowing users to use native BTC as collateral for lending without relying on wrapped BTC or centralized custody solutions.The proposal has been published on the Aave governance forum, seeking DAO approval to advance the integration and incorporate Babylon's native BTC into the V4 lending protocol's collateral assets. The proposal points out that Bitcoin is the largest crypto collateral base, but currently, most on-chain BTC lending relies on wrapped BTC variants, custodial intermediaries, or fragmented BTCfi platforms. The Aave V4 architecture will leverage Babylon's staking and validation infrastructure to provide a more direct native Bitcoin lending mechanism, integrating fragmented Bitcoin collateral lending into a unified protocol.
