Connected Networks#

Along with the endpoints listed to interact with its own networks, Flare offers public RPC nodes for a series of other blockchain networks, to bootstrap development of connected services like attestation providers.

All public RPC endpoints are experimental and rate-limited to avoid spamming attacks. For a production-grade option check out Flare's API Portal and the Google Cloud Marketplace.

Ethereum

Ethereum has two layers: the execution layer and consensus layer, which work in tandem.

  • The execution layer creates blocks with transactions and executes smart contracts.
  • The consensus layer, sometimes referred to as the beacon chain, governs consensus and was the extra layer required for the Ethereum 2.0 proof-of-stake (PoS) merge.

These two layers have their own API, which can be called from the provided nodes. When querying the Ethereum network nodes, specifying only the root path / will target the execution layer API. Prefixing your path with /eth will target the consensus layer API.

Official API specifications for each layer:
