Yearn Finance suffered an exploit on its yETH stableswap pool, resulting in an approximate loss of $9 million in assets. On November 30, 2025, at 21:11 UTC, an attacker exploited a math-related vulnerability in the pool’s custom stableswap implementation, enabling them to over-mint yETH LP tokens. They then redeemed the LP tokens, draining the underlying WETH and various liquid staking tokens (LSTs) from the affected Balancer and Curve pools. After the exploit, the attacker deposited 1,000 ETH into Tornado Cash in 100 ETH increments. The remaining stolen LSTs have not been sold. Yearn contributor banteg published a preliminary post-mortem attributing the root cause to a subtle bug in the pool’s supply solver logic within a custom version of Curve-style stableswap code. Yearn’s V2 and V3 vaults were not affected.
In coordination with the Plume and Dinero teams, Yearn successfully recovered 857.49 pxETH, worth $2.39 million, from the exploiter’s wallet. pxETH, one of several liquid staking tokens (LSTs) held in the legacy yETH stableswap pool, was recovered using a burn-and-mint mechanism that burned the tokens in the attacker’s address. The attacker still holds roughly $3.6 million in remaining LSTs, primarily frxETH, rETH, wstETH, and cbETH. Recovery efforts for the remaining tokens are ongoing. All recovered assets will be returned to users.
Today marks five years since Ethereum’s Beacon Chain launched on mainnet, with its genesis block activated on December 1, 2020. At its inception, the Beacon Chain saw approximately 500,000 ETH deposited on the first day. Today, over 35.6 million ETH, representing 29.5% of the total ETH supply, is staked on the Beacon Chain, supported by more than 10,000 node operators. The Beacon Chain has maintained 100% uptime since its launch. On September 15, 2022, it merged seamlessly with Ethereum's execution layer, marking the network’s complete transition from proof of work to proof of stake.
Amundi, Europe’s largest asset manager with over $2.6 trillion in assets under management, launched the first tokenized share class of an existing euro-denominated money market fund on Ethereum. The structure allows institutional investors to choose between the traditional fund or the new onchain fund with shares and transactions recorded directly on the Ethereum. The fund invests in short-term euro-denominated debt instruments. The rollout was developed in partnership with CACEIS, which provides the tokenization infrastructure, wallets, and a digital order-routing system for 24/7 subscriptions and redemptions. Amundi’s launch marks the first major euro-denominated tokenized fund.

The Ethereum block gas limit hit 60 million gas at block number 23,880,151. The increase was triggered automatically after more than 50% of Ethereum validators signalled the increase. On Ethereum, the L1 block gas limit can rise without a hard fork when enough validators adjust their node configurations to propose blocks with higher limits. Increasing the gas limit enables each block to carry more data, thereby boosting transaction throughput. The increase is part of broader efforts to scale Ethereum’s L1 capacity, which has doubled, from 30m to 60m just in the past year. Vitalik Buterin noted a possible 5x gas limit increase in the near future. Several active EIPs aim to push the increase further, including EIP-9698, which proposes a 100x increase over the next four years.
ZKsync published Part 2 of its ZK token extension proposal, explaining how its native interoperability can serve as the cryptographic coordination layer for institutions. ZKsync’s Interop replaces fragmented networks by enabling private and public chains to verify shared state directly via ZK proofs, while institutions can continue to use rails like SWIFT and SEPA. Built on ZKsync’s Prividium architecture, private ZK chains anchored to Ethereum, interop turns siloed workflows into verifiable, standardised events without intermediaries. As institutions coordinate across chains, the resulting message flow could form the basis for potential ZK token utility through interop verification fees. The proposal remains open to community governance feedback.
The Ethereum ecosystem, including L2 networks, hit a record peak throughput of 31,000 transactions per second in the last 24 hours. Lighter, a perpetuals-focused ZK Rollup with $1.2 billion in TVL, topped the throughput charts with about 5,455 transactions per second, followed by Base with 137 transactions per second.

Polymarket, the world's largest prediction market platform, received CFTC approval via an Amended Order of Designation, allowing it to operate as a fully regulated U.S. exchange. The approval enables intermediated trading, where users access markets through licensed brokers and FCMs, integrating with traditional custody systems. CEO Shayne Coplan praised the current administration for their speed and feedback on applications, stating that “this admin and commission are built differently.” Polymarket allows users to bet on real-world event outcomes across elections, sports, and markets.
Sunnyside Labs, a core contributor to the OP Stack, and OP Labs introduced backup sequencing on OP Mainnet, allowing the sequencer set, previously operated solely by OP Labs, to include Sunnyside Labs as a backup. A sequencer failure forces users to fall back to the slow L1 forced transaction. The new system uses op-conductor, a Raft-based program, to manage sequencer failover. There are currently five sequencers, 3 by OP Labs and 2 by Sunnyside Labs, spanning multiple cloud providers. The transition from a single operator to a multi-operator model ensures continuous block production and moves towards sequencer decentralisation for the Superchain.
GnosisDAO approved a proposal to terminate its four-year treasury management relationship with DAO treasury manager Karpatkey. The vote follows debates over costs, risk, performance, and alignment following Karpatkey’s 2024 spin-out into an independent entity. All treasury assets will be returned to direct GnosisDAO control. The assets will eventually be consolidated into sUSDS, wstETH, and Gnosis ecosystem tokens. Karpatkey, originally incubated by Gnosis in 2021, continues managing treasuries of other protocols, including the ENS DAO and Balancer.
