# Sign messages and transactions

Sign plaintext messages, EIP-712 typed data, or submit raw EVM transactions.

## Ask your agent

```text
You (to your agent): "Sign this message on Ethereum: Hello, world"

```

```text
You (to your agent): "Sign this EIP-712 typed data: <paste JSON payload>"

```

Your agent shows the exact payload and asks you to confirm before signing.

## Prerequisites

- [Quickstart](/agent-wallet/quickstart/) completed
- Understanding of what you are signing. Review payloads before confirming.

## Sign a plaintext message

```bash
mm wallet sign-message --message "<TEXT>" --chain-id <CHAIN_ID> [--wait]

```

## Sign EIP-712 typed data

```bash
mm wallet sign-typed-data --chain-id <CHAIN_ID> --payload '<JSON>' [--wait]

```

The payload must be valid JSON with `domain`, `types`, `primaryType`, and `message` fields.

## Send a raw transaction

If the calldata is unfamiliar, decode it first:

```bash
mm decode --payload <0x-calldata>

```

Then submit the transaction:

```bash
mm wallet send-transaction --chain-id <CHAIN_ID> --payload '<JSON>' [--wait]

```

The payload must include at least a `to` address. See the commands reference for the full schema. If `mm decode` returns `Call unknown function`, treat the transaction as higher risk and confirm the payload before signing.

## Polling

Signing commands can return a `pollingId` when `--wait` is omitted, in both server-wallet and bring your own wallet mode. In bring your own wallet mode, the request is signed locally and then submitted as a job, so pass `--wait` to get the result in one call. In server-wallet mode, track pending requests:

```bash
mm wallet requests list
mm wallet requests watch <POLLING_ID>

```

If the output contains `AWAITING_MFA`, the request is waiting for your 2FA approval. See [Approve requests](/agent-wallet/approve-requests/).
