Firehose chain-specific configuration for Avalanche C-Chain

This page covers Reader Node configuration specific to Avalanche C-Chain. For general Firehose architecture and deployment, see the Single Machine Deployment or Distributed Deployment guides.

Firehose for Avalanche uses an RPC poller approach. You can either run your own Avalanche node or use an RPC provider. For node setup, refer to the official Avalanche documentation.

Architecture

Firehose for Avalanche uses an RPC poller approach. The poller fetches blocks from Avalanche C-Chain RPC endpoints (which are EVM-compatible) and converts them to Firehose format.

Reader Node Configuration

Avalanche C-Chain Mainnet

fireeth start reader-node <apps> \
  --advertise-chain-name="avalanche-mainnet" \
  --common-first-streamable-block=<start-block> \
  --reader-node-path="fireeth" \
  --reader-node-arguments="tools poller optimism <rpc-endpoint> {first-streamable-block}" \
  <other_flags...>

Key Poller Flags

Flag	Description
tools poller optimism	Subcommand to run the EVM RPC poller
<rpc-endpoint>	Avalanche C-Chain RPC endpoint URL
{first-streamable-block}	Variable substituted from --common-first-streamable-block
