Every blockchain we serve
128 mainnets behind one endpoint pattern and one API key — 107 EVM chains and 21 non-EVM networks. Switch chains by changing the path segment; pricing, rate limits and authentication stay identical across all of them.
EVM Layer 1s
58Ethereum and the standalone EVM networks. Every one speaks the standard JSON-RPC surface, so MetaMask, ethers.js, viem and Foundry work unchanged.
L2s and rollups
46Optimistic and zero-knowledge rollups plus app-chains. Same EVM interface, with each network’s own confirmation and finality behaviour.
Bitcoin and friends
3UTXO chains served over Bitcoin Core-compatible JSON-RPC, with an address/index API alongside so you can query balances and history per address.
Solana
1Mainnet and testnet over the standard Solana RPC interface, including WebSocket signature and account subscriptions.
Cosmos ecosystem
12Cosmos SDK chains and their app-chains — tendermint RPC plus an EVM interface where the network exposes one.
Polkadot and Substrate
3Relay chains and system parachains over the Substrate RPC interface.
Other networks
5Non-EVM Layer 1s with their own virtual machines and RPC conventions.
Using these endpoints
- Getting started — create a key and connect in a couple of minutes; the same key works on every chain above.
- Supported chains table — the same list as copy-paste endpoint URLs, one row per chain.
- Method support — which JSON-RPC methods each EVM chain actually answers, measured weekly, including
eth_getLogsand archive availability. - Archive access — append
&archive=1to route a request only to unpruned nodes for historical state.
