Polkadot questions we get asked.
Polkadot 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 Polkadot RPC gateways with global load balancing and high uptime.
Connect to Tatum's Polkadot RPC Gateway using the endpoint format: polkadot-mainnet.gateway.tatum.io or polkadot-westend.gateway.tatum.io.
Tatum's RPC Gateway provides discovery endpoints:

- X-API-Key in header (Recommended): Pass your API key in the
x-api-keyheader - Authorization Header (Bearer): Use
authorization: bearer {YOUR_API_KEY} - Authorization Header (Basic): Use HTTP Basic Authentication
See the Authentication & Security documentation. Get your API key by signing up at the Tatum Dashboard.
