OnFinality powers Sonic with high performance RPC service
We are proud to announce RPC support for Sonic, a next-generation Layer-1 blockchain engineered for high throughput and ultra-low latency in Web3.
OnFinality provides easy to use, reliable and scalable API endpoints for builders to deploy and run their dApps on Sonic quickly and easily!
What is Sonic
Sonic is a high-speed Layer-1 blockchain optimized for real-time Web3 applications. It achieves sub-second finality and processes over 10,000 transactions per second using a Proof-of-Stake consensus. With Ethereum Virtual Machine (EVM) compatibility and a developer-first approach, Sonic makes it easy to integrate existing Ethereum-based applications. Its Fee Monetization (FeeM) program returns up to 90% of transaction fees to developers, supporting sustainable application growth in sectors like gaming, DeFi, and other latency-sensitive use cases.
By connecting to Sonic with OnFinality’s API endpoints, builders can now:
- Access the Sonic blockchain quickly in minutes without having to set up or manage infrastructure.
- Enjoy global performance, automated scalability and high availability of up to 99.99% uptime per year!
- Gain valuable API Insights for you to spot issues on your apps and quickly implement rectifications for a bug-free user experience.
We’re providing both public and private endpoints for Sonic (Public endpoints have a reasonable rate limit applied).
Simply sign up to app.onfinality.io to receive your free API key. Our ‘Free Plan’ comes with 500,000 daily responses for anyone to get started easily.
For teams looking to take applications to the next level and ensure that they receive the best performance possible, we highly recommend using an API key. What are the benefits of getting an API key?
