# Config File

Application configuration can be stored in a file and passed to the application with the `--config` flag.

Example:

```
./keep-client --config /path/to/your/config.toml start
```

Configuration files in formats TOML, YAML and JSON are supported.

Sample configuration file:

{% code overflow="wrap" %}

```toml
# This is a sample TOML configuration file for the Keep client.

# Uncomment to override the defaults for transaction status monitoring.

# MiningCheckInterval is the interval in which transaction
# mining status is checked. If the transaction is not mined within this
# time, the gas price is increased and transaction is resubmitted.
#
# MiningCheckInterval = 60  # 60 sec (default value)

# MaxGasFeeCap specifies the maximum gas fee cap the client is
# willing to pay for the transaction to be mined. The offered transaction
# gas cost can not be higher than the max gas fee cap value. If the maximum
# allowed gas fee cap is reached, no further resubmission attempts are
# performed. This property should be set only for Ethereum. In case of
# legacy non-EIP-1559 transactions, this field works in the same way as
# `MaxGasPrice` property.
#
# MaxGasFeeCap = "500 Gwei" # 500 Gwei (default value)

# Uncomment to enable Ethereum node rate limiting. Both properties can be
# used together or separately.

# RequestsPerSecondLimit sets the maximum average number of requests
# per second which can be executed against the Ethereum node.
# All types of Ethereum node requests are rate-limited,
# including view function calls.
#
# RequestsPerSecondLimit = 150

# ConcurrencyLimit sets the maximum number of concurrent requests which
# can be executed against the Ethereum node at the same time.
# This limit affects all types of Ethereum node requests,
# including view function calls.
#
# ConcurrencyLimit = 30

# BalanceAlertThreshold defines a minimum value of the operator's account
# balance below which the client will start reporting errors in logs.
# A value can be provided in `wei`, `Gwei` or `ether`, e.g. `7.5 ether`,
# `7500000000 Gwei`.
#
# BalanceAlertThreshold = "0.5 ether" # 0.5 ether (default value)

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.threshold.network/tbtc-signer-nodes/tbtc-v2-node-setup/advanced-options/config-file.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
