About
Ankr is a Web3 infrastructure platform offering remote procedure call node access to more than 30 blockchain networks through a globally distributed network of nodes run by independent operators. Unlike centralized providers that operate their own data centers exclusively, Ankr's decentralized architecture routes requests across geographically distributed nodes, improving latency for users in regions underserved by US- or EU-centric infrastructure. Its public free-tier RPC endpoints — available for Ethereum, BNB Chain, Polygon, Avalanche, Fantom, and dozens of others — have made Ankr one of the most widely used infrastructure providers in the multi-chain developer ecosystem.
