Nothing beats meeting builders IRL and jamming on the new era of zkApps. We can't wait to cowork with y'all again at the next Era zkafé ☕️. Some highlights from @token2049 🇸🇬.

📢 ZKsync RPC API update ↴. We’re deprecating legacy methods like "zks_estimateFee", "zks_getMainContract", and others. New methods like "zks_gasPerPubdata" and "debug_getRawTransactions" are now available. Low usage methods will be removed soon.

You can install it from:. 📦 NPM: 🔎 Soldeer: Note: v2-testnet-contracts is deprecated and will no longer receive updates from protocol v28 onward. Archival is scheduled.

zksync-contracts is the long-term, canonical package. Key benefits:. > Versioned by protocol.> Importable without cloning era-contracts.> Stable, pin-able dependencies for production use.

Releasing “zksync-contracts” → the official package for building on @zksync. It replaces the old v2-testnet-contracts repo. Includes full set of interfaces and helper libraries, versioned per protocol (v26.0.0, v27.0.0, etc).

Action required (if applicable) ↴. If your contracts rely on any of the deprecated methods, consider refactoring now. This is your early heads-up before we start reverting/removing behavior in upcoming versions. Not sure if you're affected? You can check the full PR and method.

Deprecation is the first step toward full removal (likely in v31 or v32). The goal → cleaner, more future-proof contract APIs for all ZKsync stack chains.

The following functions will be marked as deprecated (but still callable):. > getBatchHash.> getBatchNumberAndTimestamp.> currentBlockInfo.> getBlockNumberAndTimestamp.> blockHash.

🚨 Heads up, builders!. We're starting the deprecation of batch info methods in SystemContext.sol with v29, as part of making Era more compatible with the ZKsync OS architecture. Here's what’s changing: 🧵.
