### Run a local coin node (BTC supported)
|
||||
|
||||
Run `node bin/lamassu-coins` in the project root and select `Bitcoin`. This process will require the existence of certain environment variables that the setup will warn about.
|
||||
|
||||
Once that is done, the node needs to be run in a terminal with the following command `<YOUR_BLOCKCHAIN_DIR_ENV_VAR>/bin/bitcoind -datadir=<YOUR_BLOCKCHAIN_DIR_ENV_VAR>/bitcoin`
