Environment

Testnet

Acknowledgement

• I understand that issues are expected with the Go SDK as they are being updated.

Issue Description

In the dApp development tutorial：
singer = await new BrowserProvider(window.ethereum).getSinger();
window.ethereum error report:
Argument of type 'MetaMaskInpageProvider | undefined' is not assignable to parameter of type 'Eip1193Provider'.

Expected Behavior

able to operate normally

Code Example

const initializeProviderAndSigner = async () => {
provider = new Provider("https://sepolia.era.zksync.dev");
// Note that we still need to get the Metamask signer
signer = await new BrowserProvider(window.ethereum).getSigner();
contract = new Contract(GREETER_CONTRACT_ADDRESS, GREETER_CONTRACT_ABI, signer);
};

This seems to be an issue specific to MetaMask but please also ensure you have zkSync Sepolia added as a network in mm.

@KK-yao Make sure you're using zksync-ethers version 6.0.0 or higher. Also check if before getting the signer, you're connecting metamask with:

await window.ethereum
        .request({ method: "eth_requestAccounts" })
        .catch((e) => console.log(e));
