The upgrade turns Ethereum into a real-time liquidity hub, removing the need for separate Layer-2 liquidity pools.
Ethereum co-founder Vitalik Buterin has given a strong nod to ZKsync’s latest upgrade, Atlas, calling the team’s work “underrated and valuable.”
His post quickly drew attention across the crypto community. The update marks a major shift in how Ethereum handles speed, cost, and liquidity.
ZKsync, known for its Layer-2 scaling solution that helps Ethereum handle more transactions at lower costs, has launched its Atlas upgrade. The numbers are impressive – over 15,000 transactions per second (TPS), one-second finality, and near-zero fees.
But as ZKsync co-founder Alex Gluchowski pointed out, those numbers are “only a small part of the story.”
The bigger breakthrough lies in how Atlas changes the way Ethereum and Layer-2s interact.
Until now, each Layer-2 network – like Arbitrum, Base, or even ZKsync Era – had to maintain its own liquidity hub to process transactions smoothly. That meant fragmented liquidity and slower interactions between networks.
Atlas changes that. As ZKsync explained, “Ethereum is now the main capital hub of ZKsync.” With this upgrade, L2 chains can access Ethereum’s liquidity directly, cutting out the need for separate pools. Transactions between L2s now happen in around one second, while L1 to L2 transfers finalize faster than a single Ethereum block.

This also opens doors for institutional players and real-world asset (RWA) projects that depend on speed and trust. Instead of waiting days for funds to move, they can now settle in near real time, directly on Ethereum.
For Ethereum, this upgrade does more than boost performance. It strengthens its position as a global financial settlement layer, connecting liquidity and enabling efficient movement of capital.
Buterin’s praise is recognition that ZKsync is helping Ethereum evolve.
He wrote, “ZKsync has been doing a lot of underrated and valuable work in the Ethereum ecosystem. Excited to see this come from them!”
Atlas bridges the long-standing gap between Ethereum’s main chain and Layer-2s. It turns Ethereum into a true liquidity powerhouse, where every ZKsync chain can plug into the same pool of capital without friction.
Simply put, this upgrade takes Ethereum closer to becoming a fast, scalable, and reliable base layer for both DeFi users and institutions.
And with Buterin’s public support, it’s clear that the Atlas era has just begun for Ethereum’s next phase of growth.
