Polygon questions we get asked.
Polygon RPC is a remote procedure call interface that lets your application read blockchain data and submit transactions without running your own node. Tatum provides free and paid Polygon RPC gateways with global load balancing and high uptime.
Connect to Tatum's Polygon RPC Gateway using the endpoint format: polygon-mainnet.gateway.tatum.io or polygon-amoy.gateway.tatum.io.
Tatum's RPC Gateway provides discovery endpoints:

Credits are consumed based on the complexity and resource requirements of each RPC method:
- 2 credits for Standard RPC methods
- 5 credits for the
eth_callmethod - 50 credits for Debug and Trace methods
