nonpayable
Allows the owner (DEFAULT_ADMIN_ROLE) and blacklist managers to blacklist addresses.
Parameters
| Name | Type | Description |

approve(spender: address, amount: uint256)
nonpayable
dev: Sets `amount` as the allowance of `spender` over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an {Approval} event.

rescueTokens(token: address, amount: uint256, to: address)
nonpayable
Allows the owner to rescue tokens accidentally sent to the contract. Note that the owner cannot rescue USDe tokens because they functionally sit here and belong to stakers but can rescue staked USDe as they should never actually sit in this contract and a staker may well transfer them here by accident.

setCooldownDuration(duration: uint24)
nonpayable
Set cooldown duration. If cooldown duration is set to zero, the StakedUSDeV2 behavior changes to follow ERC4626 standard and disables cooldownShares and cooldownAssets methods.

Parameters
| Name | Type | Description |
|---|---|---|
| duration | uint24 | Duration of the cooldown |
transfer(to: address, amount: uint256)
