IB20.burnBlocked

Generated B20 reference for burnBlocked(address,uint256).

Signature

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

IB20(token).burnBlocked(from, amount);
