Darwinia Dedicated Node Infrastructure | OnFinality

Darwinia is a cross-chain programmable network built on Polkadot, offering two core solutions: Darwinia Chain and Darwinia Msgport. Darwinia Chain is an EVM-compatible smart contract platform secured by Polkadot’s relay chain, enabling fast and low-cost transactions. Darwinia Msgport is a cross-chain messaging infrastructure that allows dApps to communicate seamlessly across different blockchains, facilitating efficient interchain operations.

Why Run a Dedicated Darwinia Node?

For production applications—such as DeFi protocols, wallets, analytics tools, and gaming dApps—reliable and performant RPC access is critical. Shared public RPC endpoints can suffer from rate limits, latency spikes, and noisy neighbors. A dedicated Darwinia node provides:

• Exclusive resources: No sharing of CPU, memory, or bandwidth.
• Consistent performance: Predictable latency and throughput for your workload.
• Full control: Choose between full or archive node types, configure pruning, and access both Substrate JSON-RPC and Ethereum JSON-RPC (Frontier) APIs.
• Enhanced security: Private endpoint with IP allowlisting and DDoS protection.

Darwinia RPC Capabilities

Darwinia nodes expose both Substrate and Ethereum-compatible JSON-RPC APIs. This means you can use standard Ethereum tools (e.g., MetaMask, Web3.js, ethers.js) alongside Substrate-specific methods. Supported methods include eth_call, eth_sendRawTransaction, eth_getLogs, chain_getBlock, and many more. Archive nodes provide full historical state access for data-intensive applications.

OnFinality Managed Node Infrastructure

OnFinality offers dedicated Darwinia node deployment with:

• Managed operations: Automated provisioning, monitoring, and updates.
• Global infrastructure: Nodes deployed in multiple regions for low-latency access.
• Analytics dashboard: Track request volume, error rates, and performance metrics.
• Scalability: Easily upgrade node specifications as your project grows.

How to Get Started

1. Sign in to your OnFinality account.
2. Navigate to the Darwinia network page.
3. Deploy a dedicated node—choose full or archive, and select your desired region.
4. Obtain your private RPC endpoint (HTTPS and WSS).
5. Integrate with your application using standard JSON-RPC libraries.

Use Cases

• DeFi dApps: Reliable transaction submission and data fetching.
• Wallets: Fast balance queries and transaction history.
• Analytics & Indexing: Archive nodes for historical data.
• Cross-chain Messaging: Leverage Darwinia Msgport with a stable node backend.

OnFinality’s Darwinia dedicated node infrastructure gives you the performance and reliability needed for production workloads, without the overhead of self-hosting.
