[bug]: Connection to Sei EVM blockchain. Flow works but error is thrown #464
Description
Description
I am building a SeiEvm react-native app. We are also already hosting a Web-App that successfully integrates reowns appkit with the same chain configuration.
I have integrated the library like described in the docs and I am being prompted to my wallet and redirected after accepting the connection. I also see my address displayed in the AppKitButton. Still my logs show several errors after attempting the connection and const { address, isConnected, chainId } = useAppKitAccount(); is not resolved to a connected state.
The Error:
Connected to unsupported network
This is how I initialize appkit:
import "@walletconnect/react-native-compat";
import {
createAppKit,
defaultConfig,
AppKit,
} from "@reown/appkit-ethers-react-native";
// 3. Define your chains
const mainnet = {
chainId: 1329,
name: 'Sei Network',
currency: "SEI",
explorerUrl: "https://seitrace.com",
rpcUrl: "https://evm-rpc.sei-apis.com",
nativeCurrency: { name: 'Sei', symbol: 'SEI', decimals: 18 },
rpcUrls: {
default: {
http: ['https://evm-rpc.sei-apis.com/'],
webSocket: ['wss://evm-ws.sei-apis.com/'],
},
},
blockExplorers: {
default: {
name: 'Seitrace',
url: 'https://seitrace.com',
apiUrl: 'https://seitrace.com/pacific-1/api',
},
},
contracts: {
multicall3: {
address: '0xcA11bde05977b3631167028862bE2a173976CA11',
},
},
};
const chains: Parameters<typeof createAppKit>[0]['chains'] = [mainnet];
// 4. Create modal
createAppKit({
projectId,
metadata,
chains,
config,
enableAnalytics: true, // Optional - defaults to your Cloud configuration
});
export function WalletConnectProvider({ children }: { children: React.ReactNode }) {
return <>
<AppKit />
{children}
</>
}
