IB20.seizeWithMemo

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

Signature

IB20.sol

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 seizable 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 authorized under SEIZE_HOLDER_POLICY. Note that SEIZE_HOLDER_POLICY uses inverted semantics: from is seizable only when isAuthorized(policyId, from) returns false.
• 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.

SEIZE_HOLDER_POLICY uses inverted authorization semantics compared to normal transfer-style gating: an account is seizable when isAuthorized(policyId, from) returns false, not true. An unset slot reads as 0 (always-allow), so no account is seizable until an issuer explicitly configures the slot.
