Sign a message in Ethereum/EVM

Recommended: JavaScript SDK for React Native

While this SDK is still supported, we recommend using newer JavaScript SDK, which is optimized for React Native, but also comes with a host of other benefits.

React Native

    // Requires setting up the RN Viem extension
    // See: /react-native/wallets/viem
    import { dynamicClient } from '<path-to-your-dynamicClient>'; // extended with ViemExtension

    export const signMessage = async () => {
      const wallet = dynamicClient.wallets.primary;
      if (!wallet) return;

      const walletClient = dynamicClient.viem.createWalletClient({ wallet });
      const signature = await walletClient.signMessage({ message: 'example' });
      console.log('signature', signature);
    }
