What is an RPC provider?

In short
An RPC provider lets you query a blockchain without running a node yourself. Behind the scenes, wallets and dApps read balances and broadcast transactions through such an endpoint. That endpoint sits where it can see your IP address alongside the addresses you use.
Key points
- An endpoint for querying a chain without your own node
- Balance display and broadcasting both pass through it
- The provider can link your IP to your addresses
- An outage freezes the display, not the assets
Definition
A service that operates blockchain nodes and exposes their query interface — the RPC endpoint — so users can read from and write to the chain without running a node.
Knowing the chain's state properly means running a node that holds every block — hundreds of gigabytes plus continuous syncing, which is not realistic for most users. An RPC provider runs the nodes and exposes only the query interface.
Wallets usually ship with such an endpoint preconfigured. Showing your balance, estimating gas and broadcasting transactions all travel that route, and many wallets let you point the setting at an endpoint of your choosing.
When the endpoint goes down you see missing balances or failed sends. The assets are still on-chain, so switching endpoints restores the view. Put the other way round: the endpoint controls what you see, and a wrong response means a wrong balance on your screen.
Watch out for
- · The provider can observe which device is watching which addresses
- · An RPC endpoint of unknown origin can feed you wrong balances or fees
- · An outage stops the display; the assets remain on-chain
