Existing users can still close positions and withdraw assets.Previously, some loan positions in AlphaLend that used ALPHA as collateral experienced severe under-collateralization, leading to bad debts for the protocol. Currently, the related bad debts have been fully covered, and the protocol is solvent, ensuring user fund safety. AlphaFi will continue to cooperate with the Sui Foundation to investigate and recover related debts, and will officially exit the Sui ecosystem after the last user completes their withdrawal.

Cosmos Labs disclosed that on September 22, Neutron encountered a governance attack that led to the theft of liquidity from protocols such as Astroport, with approximately 1.73 million ATOM subsequently transferred by the attacker to Cosmos Hub. The Cosmos Hub itself was not attacked, and user funds were not affected. To prevent the stolen ATOM from being transferred out, Hub validators temporarily paused the network for about 24.5 hours and resumed block production on September 23 based on the patched Gaia v28.3.0.Cosmos Labs stated that during the pause, 1.227 million ATOM remained in the attacker's Hub address. When the network was restored, these were transferred to a 4/6 multi-signature address composed of Nansen, Keplr, Enigma, Silknodes, Kiln, and Polkachu through a one-time change. Previously, about 500,000 ATOM had been exchanged for ETH via THORChain and could not be recovered; another 169,000 ATOM entered the attacker's address after the network was restored due to THORChain refunds and were sold after being transferred to Osmosis. The current multi-signature address holds approximately 1.227 million ATOM, which can only be returned after authorization from a Cosmos Hub governance proposal. The related funds will not be staked, lent, or traded. The Neutron team expects to submit a recovery plan and related governance proposals next week.

StarkWare stated in an update on September 23 that the estimated GPU computing cost for preparing a quantum secure Bitcoin (QSB) transaction has dropped to below $67, a decrease of about 79% compared to the approximately $320 computing expenditure for the first similar mainnet transaction in August. According to StarkWare, the first QSB transaction was packaged and confirmed on August 26, with the engineering work completed by Tomer Giladi, and submitted directly through MARA's Slipstream service. The preparation process consumed about 3100 GPU hours, utilized around 100 GPUs, and incurred a computing cost of approximately $320, excluding Bitcoin network transaction fees.This cost reduction resulted from the quantum secure Bitcoin optimization challenge initiated on September 16 by StarkWare, Yukon Research, and Eigen Labs. The challenge invited developers, researchers, and AI agents to optimize transaction construction software, ultimately resulting in 62 adopted improvements across two computational tasks required to prepare a QSB transaction, with benchmark tests showing an estimated computing cost reduction of about 79%. The relevant dashboard currently indicates that the estimated cost has further decreased to $66.The QSB proposal was released by StarkWare researcher Avihu Levy in April, introducing hash-based quantum attack protection for transactions without altering Bitcoin's consensus rules. Due to limited cost, complexity, and applicability, he described it at the time as an emergency measure while continuing to advocate for adjustments at the protocol level.

The Cosmos ecosystem protocol Neutron faced a governance proposal that was manipulated by an attacker. The related address spent approximately 20,199 USDC to buy NTRN and staked 31.6 million NTRN about 12 minutes before the voting ended, ultimately allowing the proposal to pass with an 82% approval rate. Subsequently, the management rights of 11 contracts were transferred to the attacker, and they migrated to malicious code, stealing approximately 4.4 million dollars in assets.To recover the funds, Cosmos Hub validators coordinated a chain halt for nearly 24 hours and 48 minutes, and during the restart process, approximately 1.23 million ATOM were transferred from the attacker's wallet to a new address, with plans to return them to the original holders.
