How to generate a private key with Loom and get your public address

$ ./loom genkey -k priv_key -a pub_key


local address: 0x3B334bEd1e7d3e7d9214495120160D9236aCbC31
local address base64: OzNL7R59Pn2SFElRIBYNkjasvDE=

and this will create files named priv_key and pub_key, the priv_key file contains your private key that you'll use to deploy contracts to the DAppChain.

Deploy Truffle Example to a Testnet

  1. Make sure you have node and yarn/npm installed
  2. Obtain the testnet URL from PlasmaChain Testnets page
  3. Get the source:
    git clone
    cd truffle-dappchain-example
    # copy the private key generated earlier to the root directory of the example repo
    cp ../priv_key extdev_private_key
  4. If you wish to deploy the example contracts to extdev-plasma-us1 skip this step. Otherwise, add the network you wish to deploy to in truffle-config.js.
  5. Install node modules:
  6. Run deploy:
    yarn deploy:extdev
