Chainstack
Instead of running a node and manually managing that infrastructure, developers can use third-party node providers like Chainstack to execute their transactions.
The ChainStack RPC API, maintained by Chainstack Labs, provides high-performance Hyperspace testnet nodes for Filecoin builders, especially for applications built on the Filecoin Virtual Machine. The ChainStack RPC API provides both a standard endpoint and a web socket endpoint. For further information, see the official page
