Noble API

Access Noble blockchain data through the Spectrum API. Noble is a Cosmos SDK appchain purpose-built for native asset issuance, most notably native USDC inside the Cosmos ecosystem.

Available methods

Noble supports the same Cosmos SDK method set as Cosmos Hub, except getStakingRewards (Noble does not run the distribution module). See the Cosmos Hub page for full descriptions.
