IB20.unpause

Resumes one or more paused token operation classes on a B20 token.

Signature

IB20.sol

function unpause(PausableFeature[] calldata features) external;

Field	Value
Selector	0x8b93dd63
Canonical signature	unpause(uint8[])

Description

Resumes each feature listed in features. Features not listed remain in their current state. Duplicates in the array are a no-op. The call does not revert when a feature is already unpaused.

Emits Unpaused(updater, features) with the exact array passed. That array is not the resulting paused set, read isPaused(feature) or pausedFeatures() for the current state.

Parameters

Parameter	Description
features	One or more PausableFeature values to resume. Must be non-empty.

Reverts

• AccessControlUnauthorizedAccount(account, neededRole): caller does not hold UNPAUSE_ROLE.
• EmptyFeatureSet(): features is an empty array.

Access Control

UNPAUSE_ROLE gates this call. UNPAUSE_ROLE and PAUSE_ROLE are separate roles, so the account that pauses a feature does not have to be the account that resumes it.

Policy Interaction

No direct policy interaction.

Pausable Features

Value	Gates
TRANSFER	transfer, transferFrom, and memo’d variants
MINT	mint, mintWithMemo, and Asset batchMint
BURN	burn, burnWithMemo, and the deprecated burnBlocked
SEIZE	seizeWithMemo

Example

Usage Example

// Unpause BURN only; MINT remains paused if it was paused separately.
PausableFeature[] memory features = new PausableFeature[](1);
features[0] = PausableFeature.BURN;
IB20(target).unpause(features);
