Elixir has announced that they plan to allow deUSD holders to redeem their tokens for USDC through a process that will also eliminate the risk of Stream Finance cashing out their deUSD without repaying their loan. According to Elixir, "Stream comprised of 99%+ of the lending positions (and has decided to not repay or close positions)".
Elixir shuts down deUSD after Stream Finance halt
After the defi yield platform Stream Finance announced a $93 million loss, Elixir announced it would be discontinuing its deUSD synthetic stablecoin. Stream Finance owes $68 million to Elixir, and holds around $75 million deUSD.
Moonwell accrues almost $3.7 million of bad debt after oracle malfunction
The Moonwell lending protocol, built on the Base Ethereum L2, wound up with $3.7 million in bad debt after an attacker took advantage of an oracle malfunction that caused the price of wrsETH to be massively inflated. The Chainlink oracle used by the project erroneously reported that a single wrsETH token (Kelp DAO's wrapped restaked ETH) was priced at around 1.65 million ETH (~$5.8 billion). Within 30 seconds of the oracle reporting bad data, an attacker took advantage of the error to borrow huge amounts of tokens, which they then swapped to other tokens to cash out.
Ultimately the attacker profited around 295 ETH (~$1 million), but the protocol was saddled with significantly more bad debt that the team will now have to grapple with.

Stream Finance halts activity after $93 million loss
The Stream Finance defi yield project announced that "an external fund manager overseeing Stream funds disclosed the loss of approximately $93 million in Stream fund assets." Stream announced that they were in the process of withdrawing remaining liquid assets, and had halted all deposits or withdrawals. They also announced they had retained a law firm to investigate the "incident".
The project didn't disclose who the fund manager was, or the circumstances in which the "loss" occurred.
The Staked Stream USD token depegged on November 3, and crashed further following the announcement.
Balancer exploited for at least $110 million
The defi protocol Balancer suffered a major exploit that drained over $110 million across several blockchains, including Ethereum, Polygon, Base, and Sonic. Attackers exploited faulty access control in the
manageUserBalance function of Balancer's v2 smart contract, enabling unauthorized internal withdrawals. The stolen tokens included 6,850 osETH, 6,590 wETH, and 4,260 wstETH, later consolidated into new wallets likely for laundering.The exploit also impacted forked protocols like Beets Finance, which lost around $3 million. Balancer's BAL token dropped over 10% following the theft.
This was Balancer's third major security incident since 2020, despite prior audits by OpenZeppelin and Trail of Bits.
Abracadabra loses more "Magic Internet Money" to third hack in two years
In their third major hack in two years, the Abracadabra defi lending project lost $1.8 million of their Magic Internet Money stablecoin. An attacker took advantage of a bug in the project smart contracts to borrow more than their provided collateral would normally allow. The attack was funded via Tornado Cash, and the exploiter then swapped the stolen tokens for ETH and laundered them back through Tornado.
The project disclosed the theft, describing the exploit as affecting "some deprecated contracts". They downplayed the theft, saying they'd bought back the stolen assets using treasury funds.
Abracadabra previously suffered a $13 million theft in March 2025, and a $6.5 million theft in January 2024.
Hypervault rug pulls for $3.6 million
Only days after the Hypervault yield farming platform announced on Twitter that they'd surpassed $5 million in total value locked, the platform suddenly shut down its website and social media accounts. Simultaneously, the crypto security firm PeckShield observed an "abnormal withdrawal" of a large quantity of various crypto assets priced at around $3.6 million, which were swapped to 752 ETH (~$3.1 million) and laundered through Tornado Cash.
The project had attracted customers by advertising yields of 76–95%.
Shibarium bridge hit with $2.4 million flash loan attack
A bridge for Shibarium, the layer-2 network for the Shiba Inu project, was exploited for approximately $2.4 million in funds. The attacker bought 4.6 million BONE tokens (the governance token for Shibarium) using a flash loan, then used compromised validator signing keys to take control of the majority of validator power. Then, they used that control to drain around 225 ETH and 92.6 billion SHIB, together priced at around $2.4 million at the time of the theft.
The project has paused staking on the network, freezing the BONE tokens borrowed by the attacker, which may limit the attacker's profits.
Nemo Protocol exploited for $2.4 million
The Nemo Protocol on the Sui blockchain suffered a $2.4 million exploit. The defi yield infrastructure protocol acknowledged the theft shortly after, explaining they had paused the protocol smart contracts as they investigated the theft. It appears the thief was able to manipulate a price oracle, siphoning $2.4 million in USDC from the project. They then bridged the funds from Arbitrum to Ethereum.
Bunni decentralized exchange exploited for $8.4 million
The Bunni decentralized exchange was exploited for approximately $8.4 million across the Unichain Ethereum layer 2 network and the Ethereum mainnet. Bunni acknowledged the theft and paused the protocol shortly after the attack.
Arcadia Finance exploited for $3.5 million
The Arcadia Finance defi margin protocol was exploited for $3.5 million after an attacker found a vulnerability in a project smart contract. The attacker quickly swapped the stolen tokens and bridged them from Base to the Ethereum mainnet. The attacker stole the funds in two separate transactions that were more than four hours apart.
Arcadia is backed by Coinbase Ventures. The project acknowledged the hack, encouraging users to revoke permissions.
