OnFinality Launches Fast Polygon RPC and Polygon Indexers
OnFinality, a multi-chain infrastructure provider, empowers web3 developers to build on Polygon faster, with easy-to-use, reliable and scalable API endpoints.
OnFinality Now Supports Polygon – Scalable APIs for the Ethereum’s Leading Layer 2
We’re excited to announce that OnFinality now supports Polygon, a blockchain designed to help developers scale decentralised applications (dApps) on Ethereum—faster, safer, and without the gas headaches.
OnFinality will deliver reliable, scalable, and easy-to-use API endpoints for builders to launch and grow their dApps on Polygon with speed and confidence.
“We’re thrilled to expand into Polygon, reinforcing our commitment to provide a comprehensive multi-chain solution for Web3 builders across leading EVM networks.”
— Daniel, COO at OnFinality
What is Polygon?
Polygon is a leading Ethereum scaling platform that offers scalable, affordable, secure, and sustainable blockchain infrastructure for Web3. Its modular Polygon SDK framework supports building a wide range of applications, transforming Ethereum into a full-fledged multi-chain ecosystem—similar to Polkadot, Cosmos, and Avalanche—while retaining Ethereum’s security, openness, and vibrant developer community.
The network powers top Web3 projects like Aave, Uniswap, OpenSea, and is trusted by major enterprises including Starbucks, Meta, Stripe, and Adobe.
