Unlike traditional networks that rely on wrapped assets and centralized bridges, ZetaChain enables developers to interact directly with native assets across chains like Bitcoin, Ethereum, Solana, Sui, and Cosmos &#8211; all through one unified system.<\/p>\n\n\n\n<p>At its core is ZEVM, an EVM-compatible environment that adds native omnichain support. This means smart contracts deployed on ZetaChain can initiate, receive, or react to events on other blockchains &#8211; no third-party bridges required.<\/p>\n\n\n\n<p>Key features include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Zeta Chain RPC access<\/strong> for interacting with ZetaChain nodes and smart contracts in real time.<\/li>\n\n\n\n<li><strong>Cross-chain smart contracts<\/strong> capable of reading and writing to other networks.<\/li>\n\n\n\n<li><strong>Native Bitcoin and Sui compatibility<\/strong>, allowing apps to use real BTC and other assets directly.<\/li>\n<\/ul>\n\n\n\n<p>For developers, this unlocks powerful use cases &#8211; such as triggering a Bitcoin payment from an Ethereum wallet, or automating cross-chain DeFi logic &#8211; without the fragmentation and risk of traditional solutions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\" id=\"why-the-v3101-hard-fork-matters-key-fixes-for-zeta-chain-rpc-reliability\">Why the v31.0.1 Hard Fork Matters: Key Fixes for Zeta Chain RPC Reliability<\/h2>\n\n\n<p><a href=\"https:\/\/github.com\/zeta-chain\/node\/releases\/tag\/v31.0.1\">The ZetaChain v31.0.1 upgrade<\/a>, passed through governance Proposal #57 and activated at block height 8728280, focuses on protocol stability, transaction integrity, and cross-chain consistency &#8211; all essential for teams depending on Zeta Chain RPC infrastructure.<\/p>\n\n\n\n<p>In other words, this hard fork is not just another routine version bump. It introduces targeted fixes for several cross-chain execution edge cases that, if left unaddressed, could impact production applications.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"whats-new-in-v3101\">What\u2019s New in v31.0.1<\/h3>\n\n\n<p>The update brings important improvements that strengthen ZetaChain\u2019s behavior in complex transactional environments:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Stuck outbound EVM transactions<\/strong> are now resolved by dynamically applying the latest nonce, eliminating one of the key blockers in automated cross-chain workflows.<\/li>\n\n\n\n<li><strong>Bitcoin outbound flows<\/strong> are now clearly separated from inbound logic, preventing asset misrouting or logic errors.<\/li>\n\n\n\n<li><strong>Invalid Sui receiver addresses<\/strong> in cross-chain transactions are automatically reverted, helping ensure dApps never show incorrect success states.<\/li>\n<\/ul>\n\n\n\n<p>Together, these changes significantly enhance transaction determinism across chains &#8211; a must for teams building serious applications using Zeta Chain RPC endpoints.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h3 class=\"wp-block-heading\" id=\"for-developers-why-this-update-affects-you\">For Developers: Why This Update Affects You<\/h3>\n\n\n<p>If your application integrates with ZetaChain RPC &#8211; whether to trigger a Sui smart contract, monitor Solana on-chain state, or sign transactions with Bitcoin &#8211; the v31.0.1 upgrade affects your backend.<\/p>\n\n\n\n<p>Without this upgrade, developers may encounter:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Transactions that silently fail or remain stuck.<\/li>\n\n\n\n<li>Broken nonce management leading to unrecoverable EVM errors.<\/li>\n\n\n\n<li>Inconsistent state updates from non-EVM chains like Sui and BTC.<\/li>\n<\/ul>\n\n\n\n<p>To sum up, these types of bugs are hard to debug and costly to fix in production, which is why relying on managed RPC infrastructure is essential. Keeping pace with every ZetaChain hard fork and governance proposal isn\u2019t optional &#8211; it\u2019s mission-critical.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\" id=\"nownodes-your-zeta-chain-rpc-is-already-upgraded\">NOWNodes: Your Zeta Chain RPC Is Already Upgraded<\/h2>\n\n\n<p>As a trusted node provider, NOWNodes has already deployed and tested v31.0.1 across our ZetaChain mainnet infrastructure. That means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You\u2019re already live on the latest version.<\/li>\n\n\n\n<li>Your RPC endpoints are fully synchronized and tested.<\/li>\n\n\n\n<li>No action is needed from your team.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, we\u2019ve reviewed the proposal, built the new version, tested in staging, and rolled out to production &#8211; all without downtime.<\/p>\n\n\n\n<p>Moreover, our infrastructure ensures full compatibility with every new feature, fix, or chain-specific behavior introduced in the upgrade.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\" id=\"let-us-handle-the-protocol-so-you-can-build\">Let Us Handle the Protocol &#8211; So You Can Build<\/h2>\n\n\n<p>Maintaining your own Zeta Chain RPC infrastructure means monitoring proposals, running staging environments, testing for edge cases, and executing upgrades precisely at block-level cutoffs. We do all of that &#8211; so you don\u2019t have to.<\/p>\n\n\n\n<p>With NOWNodes, you get:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High-performance, secure Zeta Chain RPC endpoints.<\/li>\n\n\n\n<li>Automated upgrade handling \u2014 including testnet and mainnet forks.<\/li>\n\n\n\n<li>Developer-focused tools, docs, and monitoring.<\/li>\n\n\n\n<li>Enterprise-grade support and uptime guarantees.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\" id=\"final-thoughts\">Final Thoughts<\/h2>\n\n\n<p>In conclusion, the v31.0.1 ZetaChain hard fork strengthens the network\u2019s promise of trustless, scalable, and secure cross-chain execution. For developers using Zeta Chain RPC, the upgrade improves transaction handling, removes critical failure points, and boosts operational confidence &#8211; especially when dealing with non-EVM chains.<\/p>\n\n\n\n<p>If you\u2019re building a wallet, cross-chain DeFi app, payment gateway, or oracle service \u2014 now is the time to upgrade your infrastructure, or better yet, let NOWNodes do it for you.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h6 class=\"wp-block-heading\" id=\"get-started-with-zeta-chain-rpc-the-easy-way\">Get Started with Zeta Chain RPC &#8211; the Easy Way<\/h6>\n\n\n<p>You focus on building.
