the revolution of DeFi liquidity on Ethereum
ZKsync Interop is a local interoperability layer that might revolutionize DeFi.
It was launched yesterday by ZKsync due to the Atlas improve, and it permits all ZK Chains to work together natively with DeFi on Ethereum.
It has been launched as an answer that avoids the so-called “chilly begin” of recent chains, permitting direct entry to liquidity on Ethereum whereas sustaining its personal personal atmosphere.
Skip the chilly begin.
Launching a brand new chain often means beginning with zero liquidity. That ends right now.
With ZKsync Interop enabled by our Atlas upgade, all ZK Chains can work together natively with @Ethereum DeFi.

What’s ZKsync Interop
Technically, it’s a Layer-2 protocol on Ethereum primarily based on zero-knowledge proofs (ZK).
It was designed to resolve fragmentation points amongst completely different blockchains, because it permits ZK networks inside the ZK rollup ecosystem “Elastic Community” to speak and transact instantly with one another on the protocol degree, eliminating the necessity for third-party bridges that always introduce safety dangers and a sophisticated consumer expertise.
On this method, ZKsync Interop makes ZK blockchains extra scalable, safe, and interconnected from the outset, inheriting the safety of Ethereum with out the necessity for third-party instruments or compromises.
The way it works below the hood:
– Belongings are withdrawn in minutes to an aliased account on Ethereum.
– An interop transaction bundle is ready and executed depositing funds into Aave on Ethereum and borrowing GHO.
– Optionally, customers can bridge the borrowed tokens again to the L2… pic.twitter.com/B59cdrS6NC— ZKsync (@zksync) December 4, 2025
The Underlying Know-how
At present in DeFi, customers, apps, and liquidity are unfold throughout completely different, separate chains.
This, particularly, results in a fragmentation of capital, in addition to a poor expertise and reliance on third-party bridges weak to hacks.
ZKsync Interop goals to fully change this situation, making your complete community “elastic” as if it had been a single unified chain.
It’s primarily based on a shared bridge, aptly named Shared Bridge, able to natively connecting all ZK networks to Ethereum’s layer-1 instantly inside the protocol, thus fully avoiding the necessity to use exterior bridges.
Moreover, it’s also outfitted with a mechanism that allows direct communication between completely different ZK chains, referred to as ZK Gateway, which helps seamless cross-chain transactions, similar to token swaps between completely different chains.
Lastly, it helps varied ranges of complexity, starting from easy asset transfers to atomic operations, together with easy cross-chain swaps to information synchronization.
The Revolution
A number of the issues that will likely be potential with ZK Interop have by no means been achievable till now with out counting on third-party instruments.
For instance, will probably be natively potential to synchronize multi-bank banking directions, atomic post-trade confirmations for securities, or ISO-20022 messages for cross-border funds.
However initially, will probably be decentralized finance that may profit probably the most.
To begin with, it may finish the liquidity fragmentation throughout completely different chains, similar to Ethereum, Arbitrum, Base, Solana, Cosmos, and so forth.
It might obtain this by remodeling all of the ZK Chains into a singular and liquid atmosphere the place will probably be potential to swap completely different tokens between a sequence on ZKsync and one other with only one click on and in lower than a second.
It is going to now not be essential to make use of wrapped tokens and bridges, and there will likely be no must pay completely different charges on completely different chains.
This manner, liquidity may certainly grow to be distinctive and shared simply as it’s on centralized exchanges, whereas nonetheless remaining in a decentralized atmosphere with Ethereum because the central hub.
For now, nonetheless, solely a public demo is offered to check native interoperability, however ultimately it also needs to be usable by everybody.
The Atlas Replace: The place the Revolution Started
All this was made potential by the Atlas improve of ZKsync.
That is the principle improve of the ZKsync ZK Stack, and it was launched between late October and early November. It represents a major leap ahead for the scalability and interoperability of ZK blockchains.
This replace introduces a modular structure that addresses the “chilly begin” of recent ZK chains, particularly permitting rapid entry to Ethereum L1 liquidity with out bootstrap or bridge.
Ensures a throughput of as much as 15,000 transactions per second (TPS), with peaks of 30,000 TPS achieved throughout testing.
Moreover, it reduces charges to negligible ranges, under a thousandth of a greenback per transaction.
Enabling native interactions between ZK Chains and DeFi on Ethereum, this replace has additionally made the launch of ZKsync Interop potential.
It permits customers to signal transactions solely on its layer-2, whereas concurrently accessing the Ethereum layer-1 with none community swap.
Lastly, due to Prividiumit permits the creation of personal chains that may leverage liquidity on Ethereum whereas sustaining their very own isolation.
This replace has been instantly praised by Ethereum co-founder Vitalik Buterin as a major development in direction of safe and interoperable ZK scaling.
ZKsync has been doing a variety of underrated and helpful work within the ethereum ecosystem. Excited to see this come from them! https://t.co/coZKCfsb8h
