# IB20.seizeWithMemo

> Generated B20 reference for seizeWithMemo(address,address,uint256,bytes32).

## Signature

```solidity theme={null}
function seizeWithMemo(address from, address to, uint256 amount, bytes32 memo) external;
```

| Field               | Value                                            |
| ------------------- | ------------------------------------------------ |
| Selector            | `0xf916d81b`                                     |
| Canonical signature | `seizeWithMemo(address,address,uint256,bytes32)` |

## Description

Seizes `amount` of `from`'s balance and reassigns it to `to` in a single admin operation. Emits, in order, `Transfer(from, to, amount)`, `Memo(caller, memo)`, and `Seized(caller, from, to, amount)`. A memo of `bytes32(0)` is permitted.

Admin operation: skips allowance and the transfer policies. The membership checks are that `from` is blocked under `SEIZE_HOLDER_POLICY` and `to` is authorized under `SEIZE_RECEIVER_POLICY`.
`to` is gated by `SEIZE_RECEIVER_POLICY`, which defaults to always-allow when unset, so an unconfigured token may seize to any destination (a treasury need not be allowlisted).

## Parameters

| Parameter | Description                                 |
| --------- | ------------------------------------------- |
| `from`    | Account whose balance is being seized.      |
| `to`      | Destination address for the seized balance. |
| `amount`  | Amount to seize.                            |
| `memo`    | Memo payload.                               |

## Reverts

* `ContractPaused(SEIZE)` when `SEIZE` is paused.
* `AccessControlUnauthorizedAccount` when the caller does not hold `SEIZE_ROLE`.
* `InvalidReceiver` when `to == address(0)`.
* `AccountNotSeizable` when `from` is currently authorized under `SEIZE_HOLDER_POLICY`.
* `PolicyForbids(SEIZE_RECEIVER_POLICY, ...)` when `to` is not authorized under `SEIZE_RECEIVER_POLICY`.
* `InsufficientBalance` when `from`'s balance is below `amount`.

## Access control

`SEIZE_ROLE` gates seizure calls.

## Policy interaction

Checks `SEIZE_HOLDER_POLICY` for the holder and `SEIZE_RECEIVER_POLICY` for the destination.

## Example

```solidity theme={null}
IB20(token).seizeWithMemo(holder, destination, amount, memo);
```
