Frequently asked questions
Everything you need to know about building on Spectrum. Can't find an answer?
Talk to our teamMore than 200 blockchain networks across mainnet, testnet and devnet, over both RPC and WebSocket, with regional deployment options. View the supported networks.
Isolated capacity, predictable latency, and request limits you can plan against, instead of sharing an endpoint with everyone else.
Capacity, compute allocation and endpoints scale without planned downtime, and published compute unit and request models make that growth easy to budget.
On globally distributed infrastructure we operate ourselves, without reliance on centralised cloud providers. Spectrum Nodes holds an AICPA SOC for Service Organisations attestation for SOC 2.
