RPCs

Public RPC endpoints are available for the Calibration testnet.
These endpoints are limited to read-only Filecoin JSON RPC API calls and MPoolPush for sending messages that have already been signed.
ChainID.network contains a dynamically updated list of available RPCs along with stats like current block-height and latency. Find out more at chainid.network. Select the filter icon and click Show Testnets to view available test networks.
