You can sign messages with your smart account. This can be helpful for Permit2, SIWE, or signing the offchain orders. Signing works for both deployed and undeployed smart accounts (via ERC-6492).

​
Ethereum Signed Message (EIP-191)

To sign a message: 
const signature = await rhinestoneAccount.signMessage(
  'Hello, world!',
  chain,
)
You can also sign hex values directly: 
const signature = await rhinestoneAccount.signMessage(
  {
    raw: '0x1234',
  },
  chain,
)

​
Typed Data (EIP-712)

const signature = await rhinestoneAccount.signTypedData(
  {
    domain: {
      name: 'Ether Mail',
      version: '1',
      chainId: 1,
      verifyingContract: '0xCcCCccccCCCCcCCCCCCcCcCccCcCCCcCcccccccC',
    },
    types: {
      Person: [
        { name: 'name', type: 'string' },
        { name: 'wallet', type: 'address' },
      ],
      Mail: [
        { name: 'from', type: 'Person' },
        { name: 'to', type: 'Person' },
        { name: 'contents', type: 'string' },
      ],
    },
    primaryType: 'Mail',
    message: {
      from: {
        name: 'Cow',
        wallet: '0xCD2a3d9F938E13CD947Ec05AbC7FE734Df8DD826',
      },
      to: {
        name: 'Bob',
        wallet: '0xbBbBBBBbbBBBbbbBbbBbbbbBBbBbbbbBbBbbBBbB',
      },
      contents: 'Hello, Bob!',
    },
  },
  chain,
)

​
Configuration

​
Chain

Signatures are chain-specific (they will vary based on whether the account is deployed or not).

​
Custom signers

You can also choose which signers to sign the message with. This is helpful when you have multiple validators, use a multisig, or session keys.
