unable to create the rollup node

[uneuro]

Hi, trying to run a node but in docker logs I got this on the unichain-nod-op-node-1:

I did docker compose with all defaults, under up to date manjaro + docker Engine: 27.2.0 + Compose: v2.29.2-desktop.2

Ok I think I need to replace in .env files this setting: https://your.sepolia.beacon.node/endpoint-here with a full ETH node RPC

You need to edit Edit OP_NODE_L1_ETH_RPC and OP_NODE_L1_BEACON

You can find RPC and BEACON here : https://ethereum-sepolia.publicnode.com/?sepolia

You need an RPC, try to find a good one and replace these values on those files mentioned :

OP_NODE_L1_ETH_RPC and OP_NODE_L1_BEACON

These should be different but just for testing try it with the same.

I do have a full tutorial here : https://github.com/0xAJPanda/unichain-node

I hope it helps...

Hey all, I have two questions:

1. ShouId I be using ETH Sepolia or OPT Sepolia?
2. I'm using Alchemy and there's no Beacon API to be found for either ETH or OPT. What to do?

May be you can use public api, or I find chainstack api support this

[RumoursGR]

either

1.Sepolia.
2.I'm using dRPC.org, where the Ethereum Beacon Chain is available for both Mainnet and Sepolia.

If you choose to use it this is my referral link: https://drpc.org?ref=53deaf.

Don't forget to use the following command and jot down the node key in the end, which acts as a private key in this case:

cat ~/unichain-node/geth-data/geth/nodekey

Cheers!
