Balancer Exploited for ~$129M

🚨 Balancer Faces $128M DeFi Exploit
Exploit Hits V2 Pools: Balancer V2 pools suffered a precision error exploit on November 3, draining approximately $128 million across Ethereum, Arbitrum, Base, and other chains. PeckShield reported $128.6 million in losses. The attacker faked fees to undervalue Balancer Pool Tokens, exchanging them for ETH. Balancer confirmed V3 pools remained unaffected and announced a forthcoming postmortem with security partners.
Chains Halt and Recover: Berachain paused its network and executed an emergency hard fork to reverse $12 million in losses from its BEX Ethena/Honey tripool. Smokey the Bera stated, "Users and LPs are our priority... we coordinated validators to protect those users." Operations resumed after recovery. Polygon censored hacker transactions to freeze funds, and Sonic nullified the attacker's $S tokens through a new contract. ZachXBT noted, "Good job on putting users first," while DeFi Ignas affirmed, "Halting was the right call."
Audits Prove Insufficient: Balancer had completed over 10 audits from three firms, yet none detected the vulnerability, drawing some scrutiny. Hasu commented, "Balancer v2 launched in 2021 and is one of the most looked at and forked smart contracts since." Fraudulent on-chain messages soon appeared, falsely claiming to be from the Balancer Security Team and offering bounties to the hacker. No funds have been recovered as of yet.

☁️ EigenCloud: Verifiable Cloud & Ethereum Restaking | ![]()  | 
☁️ What is EigenCloud EigenCloud is a developer platform built on EigenLayer, Ethereum’s leading restaking protocol. Users restake ETH or EIGEN to secure DeFi, AI, and real-world applications. With over $20B in TVL and 162+ Actively Validated Services (AVSs) in development, it’s backed by a16z’s recent $170M investment. Join now: Restake to earn rewards (over $128M already distributed) or run nodes for AI inference and scaling. Just launched: Concrete’s Staked Eigen Vault delivers 8-10% real USD yield, Eigen incentives, partner rewards, and full DeFi composability.
📊 a16z State of Crypto 2025 Report In its latest State of Crypto report, a16z highlights the convergence of global infrastructure scaling, institutional adoption, and AI’s need for verifiable compute. EigenLayer now holds 10% of all DeFi TVL, more than any chain outside Ethereum. EigenCloud stands out as the full-stack solution for trusted AI agents, offering secure inference, compute, and data availability with deep liquidity and economic security. This makes restaking a foundational layer for agentic finance and autonomous systems.
🚀 EIGEN & x402: Early in the Stack Long before x402 became the standard for agent-to-agent (A2A) payments, EigenCloud shipped live verifiable workflows with Google’s AP2 in September. EigenCompute executes tasks with cryptographic proofs, EigenDA provides scalable storage for inputs and outputs across chains, and AVSs integrate trust directly into agent operations. Together, the x402 + AP2 + EigenCloud stack forms a complete verifiability layer, enabling secure, programmable interactions in the emerging agent economy.
