  +## Insufficient Funds
  +If the wallet configured in Hermes' `config.toml` is empty or doesn't have enough funds, any transfer will result in the following error:
  +```
  +ERROR ThreadId(11) send_messages_and_wait_commit{chain=ibc-0 tracking_id=ft-transfer}:send_tx_with_account_sequence_retry{chain=ibc-0 account.sequence=25}:estimate_gas: failed to simulate tx. propagating error to caller: gRPC call failed with status: status: Unknown, message: "failed to execute message; message index: 0: 20stake is smaller than 108stake: insufficient funds [cosmos/cosmos-sdk@v0.46.3/x/bank/keeper/send.go:191] With gas wanted: '18446744073709551615' and gas used: '52497' ", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc", "x-cosmos-block-height": "377"} }
  +```
  +
  +### Fix
  +In order to fix the error above, use one of the following two solutions:
  +- add enough funds to the wallet configured by `key_name` in Hermes' `config.toml`.
  +- change the wallet configured by `key_name` in Hermes' `config.toml` to a wallet which has enough funds.
