Configuration

Gossamer consumes a .toml file containing predefined settings for the node from setting the chain-spec file, to the RPC/WS server, this file allows you to curate the functionality of the node instead of writing out the flags manually

Full reference

# This is a TOML config file.
# For more information, see https://github.com/toml-lang/toml

# NOTE: Any path below can be absolute (e.g. "/var/gossamer/data") or
# relative to the home directory (e.g. "data"). The home directory is
# "$HOME/.local/share/gossamer" by default, but could be changed via
# $GSSMRHOME env variable or --home cmd flag.
