hi @betnow , I have no problem with the Ethers library example. Please check the RPC you are using (you can share with me all your configs) and also check that the Active chainId is the same one that you are using inside the domain/chain attribute in the message. ---

Domain ```auto tconst domain = { name: 'Live Betting', version: '1.0.0', chainId: 137, verifyingContract: AZURO_CLIENT_CORE, } ``` How signer is set ```auto const connectHanlder = async () => { try { if (web3Auth) { const web3authProvider = await web3Auth.connect() if (web3authProvider) { hotjar.initialize(3306401, 6); setIsConnecting(true) const web3Provider = new ethers.providers.Web3Provider(web3authProvider); //const web3 = new Web3(web3authProvider); const signerVal = web3Provider.getSigner(); const address = await signerVal.getAddress(); const accountInfo = await web3Auth.getUserInfo(); const isSocialLogin = Object.keys(accountInfo).length !== 0 const biconomySmartAccountConfig = { signer: signerVal, chainId: ChainId.POLYGON_MAINNET, bundler: bundler, paymaster: paymaster, rpcUrl: getRpc(), }; let biconomySmartAccount = new BiconomySmartAccount( biconomySmartAccountConfig ); biconomySmartAccount = await biconomySmartAccount.init(); const scwAddress = await biconomySmartAccount.getSmartAccountAddress() setEoaAddress(address?.toLowerCase()) setSmartAccount(biconomySmartAccount); setProvider(web3Provider); setSigner(signerVal) setIsConnected(true); setSocailLogin(isSocialLogin) setProvider1(new ethers.providers.JsonRpcProvider(process.env.REACT_APP_POLYGON_RPC_URL_1)) setProvider2(new ethers.providers.JsonRpcProvider(process.env.REACT_APP_POLYGON_RPC_URL_2)) setProvider3(new ethers.providers.JsonRpcProvider(process.env.REACT_APP_POLYGON_RPC_URL_3)) //setWeb3Val(web3); isSocialLogin ? setSocialInfo(accountInfo) : setSocialInfo(null) if (scwAddress?.length) { if (searchParams.get("referralID")?.length) { connectWalletAddress(scwAddress, searchParams.get("referralID"), isSocialLogin, accountInfo, address?.toLowerCase(), connectWalletCallBack) } else { connectWalletAddress(scwAddress, "", isSocialLogin, accountInfo, address?.toLowerCase(), connectWalletCallBack); } } setIsConnecting(false) return scwAddress; } } else return } catch (err) { setIsConnecting(false) //console.log(err, "here") } ``` When i use signer.signMessage ,I’m able to get the signature but Sign Typed Data v4 is failing ---
