IB20.pause

Signature

IB20.sol

function pause(PausableFeature[] calldata features) external;

Field	Value
Selector	`0xa290249c`
Canonical signature	`pause(uint8[])`

Description

Pauses each feature in features. The call is additive: features already paused remain paused, and duplicates within the array are silent no-ops. Emits Paused(updater, features) with the exact array passed. While a feature is paused, the operations it gates revert ContractPaused(feature).

Parameters

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

Reverts

AccessControlUnauthorizedAccount(account, neededRole): caller does not hold PAUSE_ROLE.
EmptyFeatureSet(): features.length == 0.

Access Control

PAUSE_ROLE gates this call. PAUSE_ROLE and UNPAUSE_ROLE are separate roles, so the account that pauses need not be the account that resumes.

Policy Interaction

No direct policy interaction.

Pausable Features

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

The ABI encodes PausableFeature as uint8, in enum order (TRANSFER = 0, MINT = 1, BURN = 2, SEIZE = 3). B20Constants.ALL_FEATURES_PAUSED (15) is the bitmask with all four set.

Example

Usage Example

// Pause MINT and BURN in one call; TRANSFER remains live.
PausableFeature[] memory features = new PausableFeature[](2);
features[0] = PausableFeature.MINT;
features[1] = PausableFeature.BURN;
IB20(target).pause(features);
