The benefits of
zkSync

Scaling freedom

zkSync offers the highest TPS and cheapest rollup costs during high-load periods. With the advanced Boojum prover and state-difference architecture, zkSync ensures unmatched performance and cost-efficiency at scale.

Native account abstraction

zkSync is the first EVM-compatible chain with native account abstraction, allowing you to build a custom paymaster to allow users to pay fees in any ERC20 token, even subsidize transaction costs for your users.

Security

zkSync prioritizes security through extensive audits from respected firms and a robust, active ZK proof system since day one, setting it apart from other L2s that may lack such measures.

The Across bridge relies on having highly accurate and live data from many networks, and therefore Alchemy has been essential to Across’ ability to support new chains quickly without experiencing liveness issues on existing chains. Our private developer support channel has been critical to our great experience with Alchemy.
