solx Beta: No stack too deep. No semantic changes.

calendar_today July 11, 2025 person zksync@newsletter.paragraph.com (ZKsync) domain zksync

With the new release, solx fixes solc’s notorious stack-too-deep failure without altering contract semantics — your contract behaves exactly as if compiled with solc, just cheaper and with fewer compilation failures. It now reliably eliminates stack-too-deep and, since our first release in May, has tightened the byte-code-size and compile-time gap while further reducing runtime gas consumption. With that, we believe solx is ready for mainnet deployment of non-critical, well-tested contracts.
