┌ ZK Stack CLI ┌ ZK Stack CLI It always shows this step which shows a different key then provided in wallets.yaml. not sure about it. I have transferred 5 sepolia eth to governor account Deploying ecosystem contracts... ◆ Address 0x4341ca72e13d3bb903a8d791cfd3a2bd784fee12 doesn't have enough money to deploy contracts only 0.000000000000000000 ETH but expected: 5.000000000000000000 ETH do you want to try again? Additional DetailsHi All, I am trying to deploy my new custom token testnet on a Sepolia L1. Please see the above configuration. I have transffered atleast 10000 Test tokens to governer, fee_account and deployer address and send 2 SepoliaETH to governer address but after creating ecosystem and trying to init the deployment doesn't process further. IT has been atleast 2-3 hours since I started. First of all if I have setup the ecosystem wrong or if the setup is wrong in any way then please advise. Also advise if I need to deploy one chain or two chains. If I use sepolia as L1 and without running the reth node tutorial as shown in https://code.zksync.io/tutorials/custom-zk-chain, if I skip this and directly deploy a chain using sepolia l1 and create the ecosystem using sepolia L1 as well, would that be ok? I really need to deploy a chain to connect to my frontedn application. Solution needed urgently. Please advice @cytadela8 @dutterbutter @bxpana @sachanayush47 and or anyone who could help. |

Hi @monk07-01! If you want to deploy to sepolia as your settlement layer, you don't need to use local reth. It looks like in both cases you have not supplied any sepolia ETH to the deployer addresses: 0x4341ca72e13d3bb903a8d791cfd3a2bd784fee12 and 0x8aa2dbe52a26e939135bbb49a31c0732e2e1f55a from your logs are empty. Please provide at least 5 sepolia ETH and try again. You can find the address in your wallets.yaml config under Feel free to unmark this as answered if this does not resolve your issue. |

Hi @ly0va . I am reading this https://docs.zksync.io/zksync-era/environment and as per this I thought that while creating ecosystem if I use Zksync Sepolia testnet and bridge the funds from sepolia ETH to Zksync Sepolia Testnet ETH and now would transfer that 5 ETH to deployer address. FYI both the above addresses that were provided in logs doesn't belong to deployer or governor cause in first case I sent 2 Sepolia ETH to both deployer and governer and then sent 5 Sepolia ETH to governor the second time . It is a different key. Please advise if I deploy using chain-id 300 as base and then in the second step deploy my custom token chain, would that work? Cause Sepolia EThereum Network is different and Zksync Sepolia Testnet Network is different Kindly advise if I would need to create two chains or just one my custom token chain with sepolia testnet or first create ecosystem keeping sepolia testnet base, chain id 300, rpc: https://sepolia.era.zksync.dev and then second chain custom token right? This time I changed config and even sent 5 sepolia eth to deployer address, still facing troubles ~/zk$ zkstack ecosystem create ┌ ZK Stack CLI ~/zk/bfh$ zkstack ecosystem init ┌ ZK Stack CLI Real address as produced by wallets.yaml file operator: blob_operator: fee_account: governor: token_multiplier_setter: |

Can you please clarify if you are trying to use Ethereum Sepolia Testnet or ZKsync Sepolia Testnet as your settlement layer? From your logs it seems that you are using the former, in which case, you have to deposit funds to deployer on Ethereum Sepolia Testnet, not ZKsync Sepoloa Testnet, so no need to bridge ETH or use https://sepolia.era.zksync.dev/ rpc. Also please double-check if you are indeed using the config you provided. When you create an ecosystem, the configs will be stored at Also please clarify what is your end goal? If you want to deploy a chain with custom base token, you can do that right away, no need to deploy 2 chains. From the logs it seems like you are choosing your base token to be Eth. For more details, please consult the launch guide |

I am trying to deploy my custom token chain using Sepolia as L1. Above I tried to build using once using Sepolia L1 as base and in another one used ZkSync Sepolia as base but none of the processes moved forward but were just loading for a few hours on the zkstack ecosystem init command. |

This error normally occurs when there is a transaction initiated from the account that was added to the mempool but wasn't committed. This can happen during network gas price fluctuations. You may try to either resume the deployment (by running the command with |

So we need 5eth in the setup so we need this much amount for mainnet as well?? @ly0va |

5 ETH is a safe recommended balance with which you will certainly not run out of funds during the deployment. I see that this prompt can be confusing, so I'll work on changing it to be more clear. |

So in mainent we need 5 eth safe to deploy this rollup.

When prompted, you can answer "No" and the deployment will continue even
if you have less funds than recommended.
I see that this prompt can be confusing, so I'll work on changing it to be
more clear.

It is more than enough; the spend is almost guaranteed to be significantly lower than that. This amount is a very conservative heuristic to be on the safe side and account for different scenarios like gas price spikes. |

You can measure the amount of funds spent when deploying on Sepolia, and convert it in mainnet prices (e.g. divide by the average Sepolia gas price and multiply by the average Ethereum Mainnet gas price) to get an estimate for how much would it cost to deploy the system on Mainnet.
