screen -S aztec

🔺🔺--- Execute below given command to Start Your node & Dont forget to make changes in it-

aztec start --node --archiver --sequencer \
  --network alpha-testnet \
  --l1-rpc-urls Eth_Sepolia_RPC \
  --l1-consensus-host-urls Eth-beacon_sepolia_RPC \
  --sequencer.validatorPrivateKeys 0xYourPrivateKey \
  --sequencer.coinbase YourAddress \
  --p2p.p2pIp Your_ip

• Replace Eth_Sepolia_RPC with your actual one! -follow above steps

• Replace Eth-beacon_sepolia_RPC with your actual one -follow above steps
