Stellar API, RPC Service & Dedicated Nodes | OnFinality

OnFinality provides managed Stellar RPC endpoints and dedicated node infrastructure for developers building on the Stellar network. Whether you are creating payment applications, wallets, or backend services, OnFinality offers reliable blockchain connectivity with observability and scaling options.

What is Stellar?

Stellar is an open-source blockchain designed for fast, low-cost cross-border payments and asset tokenization. It connects financial systems worldwide, enabling near-instant settlement with minimal fees. The network is maintained by the non-profit Stellar Development Foundation and supports a wide range of use cases including remittances, stablecoins, and decentralized finance.

Why Use Stellar RPC?

Stellar RPC provides real-time access to network data, allowing developers to query the blockchain, submit transactions, and interact with smart contracts (Soroban). It is essential for building non-custodial wallets, monitoring network activity, and integrating Stellar into existing financial infrastructure. OnFinality simplifies this by offering managed endpoints that handle node maintenance, scaling, and monitoring.

Stellar RPC Endpoints on OnFinality

OnFinality offers Stellar RPC endpoints with HTTP and WebSocket transport. Developers can create an API key through the OnFinality dashboard and connect using standard JSON-RPC methods. Endpoints are available in multiple regions, including N.Virginia, and support archive data for historical queries. For production workloads, OnFinality provides dedicated nodes with guaranteed resources and enhanced reliability.

Dedicated Nodes for Stellar

For teams requiring full control and higher throughput, OnFinality offers dedicated Stellar nodes. These nodes are isolated, providing consistent performance and access to all RPC methods. They are ideal for high-volume applications, exchanges, and institutional users who need predictable latency and uptime.

How to Connect to Stellar on OnFinality

1. Create or sign in to your OnFinality account.
2. Select Stellar from the supported networks list.
3. Create an API endpoint or deploy a dedicated node.
4. Test the endpoint using the example method chain_getBlock.
5. Monitor request usage, errors, and limits via the dashboard.

OnFinality handles node synchronization, updates, and infrastructure management, allowing you to focus on building your application.
