# mandate activate

> Set the EVM wallet address for a registered agent. Required before validating transactions.

## What does activate do?

The `activate` command sets the wallet address for an agent that was registered without one. You need a wallet address before the policy engine can validate transactions.

```bash theme={null}
npx @mandate.md/cli activate 0xYourWalletAddress
```

## When to use it

If you ran `login` without `--address`, the agent has a zero address and cannot validate transactions. Call `activate` with the wallet address your agent will use to sign transactions.

## Example

```bash theme={null}
npx @mandate.md/cli activate 0x1234567890abcdef1234567890abcdef12345678
```

## Output

```json theme={null}
{
  "activated": true,
  "evmAddress": "0x1234567890abcdef1234567890abcdef12345678",
  "onboardingUrl": "https://app.mandate.md/onboarding/..."
}
```

The command updates `~/.mandate/credentials.json` with the new address. All subsequent commands use this address automatically.

<Note>
  This command requires authentication. You must run `login` first to store a valid runtime key.
