YAML/TOML Config

You can configure Erigon using a YAML or TOML configuration file by specifying its path with the --config flag.

Note: flags specified in the configuration file can be overridden by directly setting them in the Erigon command line.

Both in YAML and TOML files boolean operators (false, true) and strings without spaces can be specified without quotes, while strings with spaces must be included in "" or '' quotes.

YAML

Use the --config flag to point at the YAML configuration file.

./build/bin/erigon --config ./config.yaml --chain=holesky

Example of setting up a YAML config file:

datadir : 'your datadir'
chain : "mainnet"
http : true
http.api : ["eth","debug","net"]

In this case the --chain flag in the command line will override the value in the YAML file and Erigon will run on the Holesky testnet.

TOML

./build/bin/erigon --config ./config.toml

Example of setting up TOML config file:

datadir = 'your datadir'
chain = "mainnet"
http = true
"http.api" = ["eth","debug","net"]
