Hi @boosik

I will discuss this matter with the team and provide you with a response shortly.

Hey @boosik looking at the code you shared and error. I would like to know few things. Why are you using the web3auth_flutter and single_factor_auth_flutter both together. Both SDKs are different and have different usecases. If you can share the use case, I could help you choose the SDK. You can also read the documentation.

The first browser error you shared of verifier not supported, SingleFactorAuthFlutter doesn’t support Sapphire Mainnet networks. The Custom Verifier you have created is on Sapphire Devnet so it won’t work with SingelFactorAuthFlutter SDK.

The second error you shared is not from Web3Auth, it’s form web3dart and looks like you are using Goreli RPC. Goreli was deprecated and no longer works. You can read the announcement.

thank you for reply @Ayush !
I am trying with Torusnetwork.testnet, and in this case goerli network may be used.
But I don’t set anything about network config… I downloaded web3dart in pubspec.yaml, but don’t use it anywhere. Can I change network setup?

Hey @boosik can you share the github repo for the code? If you are looking to use the SFA and Torusnetwork.testnet, you will need to create a verifier on Testnet in Web3Auth dashboard.

oh it finally worked with MPC(plug and play)! Thank you very much. I confused with Web3Flutter and SFA features.
