ZetaChain just rolled out one of its most important network upgrades yet - v31.0.1, a hard fork focused on making cross-chain transactions more reliable and secure. If you're using Zeta Chain RPC in production, this upgrade isn't something to overlook.
Let’s break down what changed, why it matters, and how to stay ahead without managing the complexity yourself.
What Is ZetaChain?
ZetaChain is a layer-1 blockchain built for the omnichain future. It lets developers interact with smart contracts and native assets across chains like Ethereum, Bitcoin, Cosmos, and Sui - all from a single unified platform.
Through Zeta Chain RPC, you can build applications that speak to multiple blockchains in real-time, without needing bridges or wrapped assets. That’s a game-changer for wallets, DeFi platforms, and cross-chain protocols.
What’s New in v31.0.1
The v31.0.1 hard fork, activated at block height 8728280, was approved via governance Proposal #57 and is now live on ZetaChain Mainnet. While it may look like a minor version bump, it includes several essential fixes:
-
Stuck EVM transactions fixed: ZetaChain now uses the latest nonce correctly when replacing outbound txs, solving a critical issue where transactions could freeze indefinitely.
-
Bitcoin outbound bug resolved: Transactions previously misprocessed as inbound are now handled correctly, ensuring BTC cross-chain logic is reliable.
-
Sui transaction safety improved: CCTX transactions with invalid receiver addresses are now automatically reverted, preventing lost assets or failed interactions.
Each of these fixes makes cross-chain communication more dependable - especially if your dApp relies on Zeta Chain RPC endpoints to handle real traffic.
Why Developers Should Pay Attention
Using outdated nodes or skipping upgrades can introduce serious issues into your stack — especially when it comes to cross-chain environments. This release tackles the kinds of edge cases that don’t show up in testnets but cause friction in production.
If you're building with Zeta Chain RPC, here’s why v31.0.1 matters:
-
Fewer stuck transactions
-
More accurate cross-chain state
-
Improved security when interacting with Sui and Bitcoin
-
Better error handling for wallets and bridges
This is an infrastructure-level upgrade, and skipping it could result in broken UX or failed backend logic.
How to Stay Updated - Without the Stress
Keeping up with every ZetaChain hard fork, proposal, and RPC-level change takes time — and getting it wrong can lead to downtime, sync issues, or even user fund errors.
