Hi everyone, i am trying to follow along the LZ-OFT-V2-Core-Guide tutorial.
I set the same configs that are proposed, and at the Deploying step, if fails every time for the Base-Sepolia network only (not the coredao) with this error :
√ Do you want to continue? … yes
Network: base-sepolia

But my rpc endpoint is valid, so i don’t understand the error here.
If someone can help me on this ?

Hi,

Thanks for sharing the details. It looks like your deployment to coredao-testnet was successful, but the deployment to base-sepolia failed due to a ProviderError. Even though your RPC endpoint might be valid, this error usually means Hardhat is unable to establish a working connection through that endpoint.

Here are a few things you can check:

  1. Double-check your hardhat.config.ts for base-sepolia
  2. Ensure the url for the base-sepolia network is correct and live or try using different public rpc url’s
  3. Try with different network like Optimisum or arbitrum sepolia
