Arbitrum Security Council Moves To Correct 51M ARB Voting Power Discrepancy

Arbitrum's Security Council has initiated a non-emergency governance action to correct a discrepancy in the recorded total Delegated Voting Power within the ARB token contract. The recorded total was approximately 51.17 million ARB higher than it should have been, stemming from initial initialization estimates. The action does not affect individual ARB token balances or delegation distributions and requires no user action. It is strictly a correction of the aggregate accounting figure used by the contract to ensure accurate governance tracking for quorum and proposal outcomes. The Security Council's proposal allows for a transparent 14-day execution period, emphasizing that this is a routine maintenance fix for governance infrastructure rather than an emergency or a change to user holdings.

Blockchain Platform WEMIX Hacked for $6.25 Million

Hackers exploited administrator privileges of a smart contract on the WEMIX blockchain platform, minting approximately 5.23 million unbacked $WEMIX tokens worth about $5.22 million. These tokens were swapped on a decentralized exchange for 30,736 $WEMIX and 724,198.27 $USDC.e, a version of USDC native to the WEMIX3.0 network. The attackers then bridged the $USDC.e to Ethereum and BNB Smart Chain, converting the funds to ETH and USDT and distributing them across multiple wallets, with some reportedly sent to centralized exchanges. Total losses are estimated at $6.25 million. In response, WEMIX halted nearly all services, suspended cross-chain bridges, and froze trading in affected liquidity pools. The platform is seeking to have the withdrawn assets frozen on exchanges. The incident caused the WEMIX stablecoin to depeg, plummeting 98% to $0.01. This follows a previous hack in February 2023, where attackers stole $8.65 million worth of $WEMIX from the Play Bridge.

Garden Finance disables app as Blockaid reports $450,000 exploit

Garden Finance has temporarily taken its app offline following an incident reported by Blockaid involving approximately $450,000. Blockaid stated an attacker drained funds from Garden's hash time-locked contracts (HTLCs) on multiple blockchains. However, Garden Finance clarified that its protocol and HTLC smart contracts were not compromised. The company attributed the loss to a breach of an independent solver's off-chain database, where fraudulent records caused the solver to release its own funds for unfunded swaps. Garden emphasized no user funds were lost or at risk, with the incident confined to solver-owned assets. The firm is working with security companies to trace and recover the funds and expects to restore services after completing security reviews. This follows a previous solver-related breach in October 2025.

Fears of AI-driven DeFi hack epidemic overstated for now — but not for long

Fears of an AI-driven "hackpocalypse" in DeFi are currently overstated, as data shows a decline in median hack sizes and total monthly losses. The primary causes of major 2026 crypto thefts—like the $763 million lost in Q2—remain traditional issues like compromised keys and operational infrastructure, not novel AI-created exploits. However, security experts warn this is a lull before the storm. AI is already industrializing attacks by scaling existing methods: analyzing vast codebases to find old vulnerabilities, automating scams to make them 4.5x more profitable, and generating deepfakes for impersonation fraud. The technology acts as a force multiplier, removing traditional bottlenecks like technical expertise. While also empowering defenders, AI’s growing capability to cheaply and rapidly identify targets means the threat landscape is fundamentally changing, even if the root vulnerabilities are not.

Uniswap Token Jar: Unlocking Protocol Revenue Through Burning, New Gameplay Live on 11 Chains

Uniswap’s "Token Jar" mechanism links protocol revenue directly to UNI token burns. The smart contract accumulates a share of fees from Uniswap transactions across 11 chains, and funds can only be withdrawn by permanently burning UNI. This system, enacted after the UNIfication governance vote in December 2025, turns token destruction into a core requirement for accessing protocol income. The recent launch of Robinhood Chain, where Uniswap serves as the native exchange, has dramatically boosted volumes—reaching $3.75B in daily trades—pushing daily UNI burns to a record 186,000 tokens. New proposals aim to extend the fee model to Robinhood Chain and activate v4 fees on seven major chains, potentially accelerating the burn cycle. This creates a reinforcing loop: more chain adoption drives more fees into the Jar, requiring more UNI burns to unlock them. While concerns remain about liquidity provider margins, the design aligns incentives across the ecosystem and transforms UNI from a pure governance token into one with a direct claim on protocol revenue.

How to spot a crypto scam or a rug pull?

Rug pulls typically begin with seemingly legitimate projects exhibiting rising prices and active communities, but end with developers withdrawing liquidity. These scams often involve manufacturing trust through locked liquidity and renounced contracts, then creating hype on social media. The process from hype to exit can occur in 48-72 hours. There are "hard" rug pulls involving immediate liquidity drainage and "soft" ones that gradually erode value through insider selling or abandoned development. Key warning signs include high wallet concentration (e.g., top 5-10 holders controlling over 30% of supply), lack of vesting for developer allocations, and quickly expiring liquidity locks. Smart contract risks stem from unverified code, hidden mint functions, upgradeable contracts, and sell restrictions. Market behavior red flags are rapid price surges driven by influencer promotion, low organic trading volume, and slowing holder growth before large developer withdrawals. Common exploit types are honeypots (trapping investors by blocking sells, accounting for ~98k scam tokens), hidden mint functions (~61k cases allowing post-launch supply inflation), and fake ownership renunciations (~49k cases). Ultimately, genuine decentralization is determined by developers relinquishing control through transparent vesting, verified code, and third-party audits.

Aurora EVM Network Halts Mainnet Operations as TVL Collapses 99% From Peak

On July 20, 2026, the Aurora EVM network, which runs on the NEAR Protocol, suffered a complete mainnet outage after block production unexpectedly halted. This caused an immediate stop to all transactions and smart contract executions. Despite securing investments from top venture firms, Aurora's team remained silent for hours and failed to provide a technical explanation or recovery timeline, leaving developers and users in suspense. The incident occurs as part of a broader decline in the NEAR ecosystem. Aurora's total value locked (TVL) has collapsed by over 99% from its 2022 peak of nearly $2.5 billion to just around $4.65 million. This prolonged low liquidity meant fewer users were active during the outage, which garnered minimal reaction from the broader crypto market, highlighting the platform's diminished presence. To rebuild confidence, Aurora's team must resume block production, conduct a root cause analysis, and establish clear communication regarding the network's recovery.

CT3 Announces Dedicated Storage Contracts to Expand Decentralized Storage Infrastructure

CT3 has transitioned its decentralized storage infrastructure to a dedicated Storage Contracts model to support platform growth, improve scalability, and expand storage capacity. This move follows rapid ecosystem growth with over 180,000 users and 500,000 uploads, each linked to an NFT access key. The new architecture distributes new uploads across multiple independent Storage Contracts, each linked to a fixed storage capacity, rather than relying on a single main contract. This segmentation enhances infrastructure resilience, allows for independent scaling of platform areas, and improves transparency in measuring resource utilization. Participants can finance the deployment of new Storage Contracts. The allocated capacity is used to store files uploaded via ct-3.cloud, and the resulting profit is shared between the investor and CT3. Financial performance depends on actual capacity utilization and the service margin. Each contract's operation is verifiable on-chain through its smart contract, with stored files represented by NFT keys containing storage metadata. This allows independent verification of key issuance, data volume, capacity utilization, and activity. For ct-3.cloud users, the transition requires no action, and existing NFT keys remain supported.

Inside Bonzo Lend’s $9M exploit – Why secure smart contracts couldn’t stop it

Bonzo Lend, a lending protocol on the Hedera network, suffered a $9.05 million exploit due to a flaw in the external Supra oracle system. The attacker manipulated SAUCE token price feeds, enabling them to borrow assets far exceeding their collateral. Audits confirmed the protocol's own smart contracts and the Hedera core network were secure; the failure originated in the trusted oracle infrastructure. This incident highlights a recurring DeFi risk where correct protocol logic can still be weaponized via compromised external data. The attack impacted market sentiment, causing a drop in HBAR's price and Hedera's DeFi TVL, underscoring the need for stronger oracle safeguards and verification standards.
