Generate P2P node key​

cd $HOME/.NullaNetwork && ./nulla-relay key generate-node-key \
  --file $HOME/.NullaNetwork/node.key

Show your peer ID (share this if you want to be added as a bootnode)​

cd $HOME/.NullaNetwork && ./nulla-relay key inspect-node-key \
  --file $HOME/.NullaNetwork/node.key

Insert session keys​

Generate a mnemonic (or use an existing one — keep it secret):

cd $HOME/.NullaNetwork && ./nulla-relay key generate --scheme sr25519

Insert all 6 key types from the same mnemonic.

Replace the value below with your own 12-word mnemonic phrase generated above.

Keep this mnemonic secret. Do not share it with anyone.

MNEMONIC="your twelve word mnemonic phrase here"

MNEMONIC="your twelve word mnemonic phrase here"

KEYSTORE=$HOME/.NullaNetwork/chains/nulla_mainnet/keystore
cd $HOME/.NullaNetwork
mkdir -p $KEYSTORE
chmod 700 $KEYSTORE

for TYPE in babe gran audi asgn para; do
  SCHEME=sr25519
  [ "$TYPE" = "gran" ] && SCHEME=ed25519

  ./nulla-relay key insert \
    --keystore-path $KEYSTORE \
