The signer configuration file is a TOML file that contains the configuration options for your signer. Below are the options you can set in the signer configuration file.
| Name | Required | Description |
|---|---|---|
| node_host | ✓ | IP:PORT where your Stacks node can be accessed. The port 20443 is the default RPC endpoint for Stacks nodes. Note that you must use an IP address - DNS hosts are not supported at this time. |
| endpoint | ✓ | IP:PORT where the signer will expose an RPC endpoint for receiving events from your Stacks node. |
| stacks_private_key | ✓ | Hex representation of the signer's Stacks private key used for communicating with the Stacks Node, including writing to the Stacker DB instance. |
| network | ✓ | Network to use. One of "mainnet", "testnet" or "mocknet". |
| auth_password | ✓ | Authorization token for HTTP requests made from the signer to your Stacks node. |
| db_path | ✓ | Path to the signer's database file |
| block_proposal_timeout_ms | Specifies the maximum time (in milliseconds) a signer waits after a Bitcoin block for a miner to produce their first Nakamoto block. If the miner exceeds this time, the signer marks their tenure as invalid and rejects subsequent block proposals. Default value of 600_000 (10 minutes). | |
| metrics_endpoint | IP:PORT for Prometheus metrics collection. | |
| chain_id | An optional ChainID, only used for custom networks (like Nakamoto Testnet) |
Below are sample configuration files for running a Stacks node and signer provided in one place for convenience. You'll need to modify some of these according to the How to Run a Signer doc.
# The IP address and port where your Stacks node can be accessed.
# The port 20443 is the default RPC endpoint for Stacks nodes.
# Note that you must use an IP address - DNS hosts are not supported at this time.
# This should be the IP address accessible via Docker, usually via a network.
node_host = "127.0.0.1:20443"
# This is the location where the signer will expose an RPC endpoint for
# receiving events from your Stacks node.
endpoint = "127.0.0.1:30000"
# Either “testnet” or “mainnet”
network = "testnet"
# this is a file path where your signer will persist data. If using Docker,
# this must be within a volume, so that data can be persisted across restarts

# an authentication token that is used for some HTTP requests made from the
# signer to your Stacks node. You’ll need to use this later on when configuring
# your Stacks node. You create this field yourself, rather than it being generated
# with your private key.
auth_password = "$your_http_auth_token"
# This is the privateKey field from the keys you generated in the
# previous step.
stacks_private_key = "$your_stacks_private_key"{% hint style="warning" %}
Note that the block_proposal_token field has changed to auth_token in the Stacks node configuration file.
{% endhint %}
This is the configuration you'll need to run a Stacks follower node if you are also running a signer. Be sure to change the commented lines to the appropriate data for your setup. If you are not familiar with the process of setting up a signer, be sure to follow the How to Run a Signer guide.
An overview of all Stacks node configuration options can be found in the Stacks Node Configuration doc.
Additions necessary specifically to run a signer are the [connection_options] and [[events_observer]] sections and the stacker = true line. There are also a few comments detailing other lines that need to change.
