# IB20.burnBlocked

> Generated B20 reference for burnBlocked(address,uint256).

## Signature

```solidity theme={null}
function burnBlocked(address from, uint256 amount) external;
```

| Field               | Value                          |
| ------------------- | ------------------------------ |
| Selector            | `0xec0cf3dc`                   |
| Canonical signature | `burnBlocked(address,uint256)` |

## Description

DEPRECATED. Burns `amount` from a `from` account that is blocked under `TRANSFER_SENDER_POLICY`, without spending an allowance. Retained for back-compat; prefer `seizeWithMemo` (to a treasury/self address) followed by `burn`. Emits `Transfer(from, address(0), amount)` and `BurnedBlocked(caller, from, amount)`.

Gated by `BURN_BLOCKED_ROLE` and the `BURN` pause vector (not `SEIZE`). Its blocked check reads `TRANSFER_SENDER_POLICY`, distinct from `seizeWithMemo`'s `SEIZE_HOLDER_POLICY`.

## Parameters

| Parameter | Description                                    |
| --------- | ---------------------------------------------- |
| `from`    | Account whose blocked balance is being burned. |
| `amount`  | Amount to burn.                                |

## Reverts

* `ContractPaused(BURN)` when `BURN` is paused.
* `AccessControlUnauthorizedAccount` when the caller does not hold `BURN_BLOCKED_ROLE`.
* `AccountNotBlocked` when `from` is currently authorized under `TRANSFER_SENDER_POLICY`.
* `InsufficientBalance` when `from`'s balance is below `amount`.

## Access control

`BURN_BLOCKED_ROLE` gates deprecated blocked-burn calls.

## Policy interaction

Checks `TRANSFER_SENDER_POLICY`; the account can be burned only when not authorized by that policy.

## Example

```solidity theme={null}
IB20(token).burnBlocked(from, amount);
```
