  -k, --key string                       select the key to use [fuji/devnet only]
  -g, --ledger                           use ledger instead of key (always true on mainnet, defaults to false on fuji/devnet)
      --ledger-addrs strings             use the given ledger addresses
      --node-endpoint string             gather node id/bls from publicly available avalanchego apis on the given endpoint
