The Fusaka upgrade is scheduled to go live on Ethereum mainnet on December 3, 2025, at 21:49:11 UTC. Node operators must update both their Execution and Consensus Layer clients to the latest versions before activation. Fusaka brings 13 EIPs with improvements to scaling, performance, and developer and user experience. The Ethstaker community will be hosting a watch party on the Ethereum YouTube channel starting 30 minutes before the scheduled fork activation. The Nethermind team is also hosting a separate 2-hour livestream featuring guest speakers across core clients and research teams, including EF Co-ED Tomasz Stanczak.

Optimism activated the Jovian Hard Fork on the Superchain, introducing improvements to fee mechanisms, maintenance updates to the fault-proof Cannon VM, and new data-availability protections. The upgrade allows chains to optionally set a minimum base fee to shorten priority-fee auctions. It also introduces an in-protocol limit on Data Availability footprint to reduce DA spam and fee-auction manipulation. The upgrade is now live for Superchain members, including OP, Base, Soneium, Ink, Unichain, Metal, Mode, and Zora.

Uniswap integrated Revolut, Europe’s largest neobank, into the Uniswap Web App and Wallet, enabling users to buy crypto directly using their Revolut balance, Revolut Pay, cards, or mobile wallets. Revolut offers 0% fees when using Revolut Pay, requires no additional identity checks for existing users, and offers over a dozen fiat currencies. The integration expands Uniswap’s onramp options, including Robinhood, Transak, and MoonPay, and supports 40+ tokens. Revolut currently only supports onramping, with plans to enable offramping in the future.

MetaMask introduced Transaction Shield, a new paid subscription service that provides users with up to $10,000 in loss protection on certain onchain transactions. The subscription also includes priority access to MetaMask support. The protection applies to DeFi swaps and lending on verified apps, NFT mints and marketplace sales, and airdrop claims from verified smart contracts. The insurance product does not cover losses from compromised wallets or protocol-level exploits. Transaction Shield builds on MetaMask’s existing safety infrastructure, including automated transaction simulations and contract risk checks, and is currently available on the MetaMask browser extension.

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.
