Ecosystem News ============== [Kelp DAO Loses $293M in Bridge Exploit, Leaving Aave With Over $200M in Bad Debt](https://thedefiant.io/news/defi/aave-price-crash-kelpdao-exploit-whale-dump-rxi8o9) ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- Kelp DAO lost about $293 million in a major exploit after an attacker tricked its bridge into creating unbacked rsETH tokens and used them as collateral on Aave to borrow real assets. The attacker acted quickly, completing the attack in under an hour before the system was frozen, leaving Aave with over $200 million in bad debt. This caused panic withdrawals, drained billions in liquidity, and pushed Aave’s lending pools to their limits. Other platforms froze rsETH, and concerns spread across DeFi, making this the largest exploit of 2026 and exposing weaknesses in cross-chain bridges and risk controls. [Class Action Lawsuit Filed Against Circle Over Drift Protocol $280 Million Hack: Gibbs Mura Law Group](https://thedefiant.io/news/hacks/class-action-drift-protocol-circle-usdc-bridge-2o1poy) ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- A law firm, Gibbs Mura Law Group, has filed a class action lawsuit against Circle Internet Financial on behalf of investors affected by the Drift Protocol hack. The lawsuit claims Circle failed to freeze about $230 million in stolen USD Coin, even though it could do so, allowing attackers reportedly linked to North Korea to move funds freely for hours. The April 1 exploit caused major losses, sharply reduced Drift’s total value, and affected many other DeFi platforms, raising concerns about Circle’s security and compliance during large-scale crypto breaches. [Singapore-based Cobo launches agentic wallet with guardrails for AI-led onchain execution](https://www.theblock.co/post/397856/cobo-launches-agentic-wallet) ------------------------------------------------------------------------------------------------------------------------------------------------------------- Cobo has launched a new “Agentic Wallet” designed to let AI agents manage crypto assets safely. The wallet uses a special system called a “Pact” to control what the AI can do, setting clear limits on actions and stopping conditions to prevent misuse. It also uses strong security methods, such as multi-party computation, to ensure that even if an AI or system is compromised, it cannot act on its own to move funds. The wallet works with popular AI tools and supports many blockchains, including Ethereum and Solana. This launch reflects a growing trend, as companies like Coinbase and Ledger also explore AI-powered wallets that can handle transactions and manage funds automatically. [Tether Commits $127.5M to Drift Protocol Recovery Plan Following $270M+ Exploit](https://thedefiant.io/news/defi/tether-commits-over-usd127m-to-drift-protocol-recovery-plan) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Tether has committed up to $127.5 million to help Drift Protocol recover from its recent $270M+ hack, as part of a larger $150 million recovery plan. The funding will help repay affected users over time as the platform restarts and generates trading revenue. As part of the relaunch, Drift will switch its main trading settlement asset from USD Coin to Tether on Solana. The move aims to rebuild confidence in the platform, and the news has already boosted Drift’s token price, showing renewed optimism despite the earlier losses. **_WAGMI!_** ============ --- *Originally published on [Probably Nothing](https://pn.developerdao.com/issue-217)*
