Spectrum Nodes

Wallets

Balances, portfolios, NFTs, token prices and name resolution across 200+ networks, from one typed API. Integrate once instead of maintaining a provider per chain.

One integration, every chain

The same call shape works across mainnets, L2s and the long-tail networks most providers never support.

Portfolios out of the box

Balances, token metadata, NFTs and prices arrive already joined, so you are not reconciling three feeds yourself.

Built for wallet latency budgets

Geo-distributed bare-metal nodes with a 99.99% uptime SLA, so a balance refresh does not stall the UI.
