Operations
What operators get
- Uptime & failover: Redundant nodes and automatic failover across regions — 99.93% measured availability on the public fabric.
- Protocols: JSON-RPC, WebSocket, Tendermint RPC, gRPC, and Substrate APIs matched to each chain category.
- Limits & SLAs: Public tiers for builders; paid and private tenancy for higher RPS, ACLs, and dedicated capacity.
- Node modes: Full, pruned, and archival endpoints where the network supports them — see each network page for details.
Chain categories
EVM: Ethereum and L2s (Arbitrum, Base, Optimism, and others) for wallets, DeFi, and indexing.
Cosmos: Tendermint / REST / gRPC for Hub, Osmosis, Lava, Injective, and peer chains.
Polkadot: Substrate RPC for relay and parachain workloads.
How to start
Open a network page, copy the endpoint URL, and plug it into ethers.js, viem, web3.js, or a Cosmos client. Use the plan calculator for usage estimates, or the cabinet for API keys.
