The world of Web3 development is evolving rapidly, and scalability remains a top priority for developers building decentralized applications (dApps). In response to this growing demand, Ankr has expanded its robust RPC infrastructure to support X1, the innovative layer 2 network powered by OKX. This integration marks a significant milestone for developers seeking high-performance, reliable, and scalable access to the X1 ecosystem.
With Ankr’s new X1 RPC endpoints, developers can now seamlessly connect their wallets, dApps, or command-line tools to the X1 network without the complexity of running their own nodes. Whether you're building the next generation of ZK-powered dApps or integrating cross-chain functionality, Ankr delivers low-latency, geo-distributed node access that ensures speed, reliability, and consistency.

What Is X1?
X1 is a ZK-powered Layer 2 blockchain designed to bridge the OKX and Ethereum ecosystems, enabling a seamless, global on-chain experience. Developed by OKX, X1 serves as a strategic gateway into Web3—connecting users, products, and digital assets across platforms. Built using the Polygon CDK (Chain Development Kit), X1 leverages zero-knowledge technology to deliver fast transaction finality, enhanced security, and full EVM compatibility.
This means developers can deploy existing Ethereum smart contracts on X1 with minimal changes, while benefiting from lower fees and higher throughput. The network uses OKB as its native token, facilitating smooth value transfers between OKX and the X1 chain.
Key features of X1 include:
- Full EVM Compatibility: Run Ethereum-based dApps with no code modifications.
- zkEVM Architecture: Benefit from secure, scalable transactions powered by zero-knowledge proofs.
- Unified Liquidity & Data Availability: Built on Polygon CDK for independent data layers and cross-chain interoperability.
- Trusted Infrastructure: Securely deploy smart contracts and onramp assets from OKX, Ethereum, and other connected chains.
- Web3 Gateway: Access the decentralized ecosystem through OKX Wallet, equipped with modular tools for innovation.
X1 isn’t just another scaling solution—it’s a bridge between centralized exchange capabilities and open Web3 development. It empowers builders to create user-friendly, high-performance applications that tap into a vast user base.

Understanding Ankr’s X1 RPC Service
Remote Procedure Calls (RPCs) are the backbone of blockchain interaction. They allow applications to communicate with blockchain nodes, retrieve data, send transactions, and verify on-chain activity. Without RPCs, dApps would have no way to interact with the underlying network.
Ankr’s X1 RPC service acts as a high-performance bridge between your application and the X1 blockchain. Instead of setting up and maintaining your own full node—a time-consuming and resource-intensive task—developers can use Ankr’s globally distributed RPC endpoints to access real-time blockchain data instantly.
Why Choose Ankr for X1 Connectivity?
- Geo-Distributed Nodes: Ankr operates a global network of nodes, ensuring minimal latency and maximum uptime no matter where your users are located.
- Public & Premium RPC Access: Choose between free public endpoints or upgrade to a premium plan for higher rate limits and dedicated resources.
- Identical Node-Level Data: Responses from Ankr’s RPCs mirror what you'd get from running your own X1 full node—accurate, consistent, and reliable.
- Developer-First Tools: Designed with scalability in mind, Ankr supports standard EVM JSON-RPC methods, making integration straightforward.
By abstracting away the DevOps burden, Ankr enables developers to focus on what matters most: building innovative dApps.
How X1 RPCs Empower Developers
Building on a Layer 2 network like X1 offers immense advantages in speed and cost-efficiency—but only if you have reliable access to the chain. That’s where Ankr’s RPC infrastructure becomes indispensable.
Eliminate Complex Node Management
Running and maintaining blockchain nodes requires specialized knowledge, constant monitoring, and ongoing maintenance. With Ankr’s managed RPC service, developers eliminate the need to:
- Procure server infrastructure
- Configure node synchronization
- Handle software updates or downtime
Instead, you get plug-and-play access to the X1 network—ready within minutes.
Accelerate Development with Premium Features
For teams building production-grade applications, Ankr offers a Premium RPC Plan that unlocks advanced capabilities:
- High Throughput: Up to 1,500 requests per second
- Dedicated Endpoints: Isolated connections for stable performance
- Priority Request Routing: Reduced latency during peak usage
- WebSocket Support: Real-time event streaming for dynamic dApps
These tools are essential for DeFi platforms, NFT marketplaces, gaming dApps, and any application requiring real-time blockchain interaction.
Support a Decentralized Network
Ankr doesn’t just provide access—it strengthens the entire X1 ecosystem. By contributing to a more distributed node network, Ankr helps improve the resilience and decentralization of X1, reducing reliance on centralized gateways.
How to Make Your First Call to X1
Getting started is simple. Follow these steps to begin interacting with the X1 blockchain:
- Visit Ankr’s RPC Dashboard
- Locate the X1 network under supported chains
- Copy your unique RPC endpoint (available for both HTTP and WebSocket connections)
- Use standard EVM JSON-RPC methods like
eth_blockNumber,eth_getBalance, oreth_sendRawTransactionin your code
Example request:
curl -X POST https://rpc.ankr.com/okx_x1 \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'Within seconds, you’ll receive a response from the X1 chain—no node setup required.
Frequently Asked Questions (FAQ)
Q: Do I need an API key to use Ankr’s X1 RPC?
A: Yes, for both public and premium access. You can generate a free API key instantly on Ankr’s platform.
Q: Is there a rate limit on the free tier?
A: Yes, the public endpoint has fair-use rate limits. For higher throughput, consider upgrading to the Premium RPC Plan.
Q: Can I use Ankr’s X1 RPC for mainnet and testnet?
A: Currently, Ankr supports X1 mainnet. Testnet availability may be added in future updates.
Q: Is my data secure when using Ankr’s RPC?
A: Absolutely. All requests are encrypted via HTTPS/WSS, and Ankr does not store or access your private keys or transaction data.
Q: How does X1 differ from other zkEVM chains?
A: X1 is uniquely positioned as a bridge between OKX’s ecosystem and Ethereum, offering direct asset onramps and a large user base from day one.
Q: Can I stake OKB on X1 through Ankr?
A: Staking is not currently supported via Ankr’s RPC. For staking options, refer directly to OKX’s staking services.
