The following core operations are halted when the vault is paused:

• All request types - Any pending or new requests are blocked, including:

  • cancelRequestDeposit()

  • withdraw()

  • redeem()

  • settleRedeem()

  • initiateClosing()

  • close()

• NAV proposals - The NAV update proposal functionality is disabled, including:

  • updateNewTotalAssets()

• Share transfers - The _update() function is paused resulting in all transfers of shares being blocked

• Operator operations - The setOperator() function is disabled

Usage example

You can also call pause from etherscan or any other Ethereum client that allows contract interaction

Events
