# Guard signer

Guard signer approval helpers.

`client.GuardSigner` manages approvals for protected funding account-control actions.

| Method                          | Purpose                         |
| ------------------------------- | ------------------------------- |
| `GetStatus` / `CreateWallet`    | Guard wallet state/provisioning |
| `SignProtectedAction`           | One approval                    |
| `BatchSignProtectedActions`     | Multiple approvals              |
| `RotateWallet` / `ExportWallet` | Guard key lifecycle             |

```go
status, err := client.GuardSigner.GetStatus(ctx, nil, nil)

chainID := 6
approval, err := client.GuardSigner.SignProtectedAction(
	ctx,
	"add_allowed_external_destinations",
	nil, nil,
	&chainID,
	[]string{"0x..."},
	nil, nil,
)
```

The action determines which optional fields are required. These are authenticated control-plane mutations: do not retry blindly and never log approvals or exported key material.

An approval does not submit an on-chain transaction. Combine it with the matching [Chain helper](https://testnet.polyester.com/docs/sdk/go/reference/chain) and verify the receipt/final state.
