0x82b42900: Unauthorized

error Unauthorized()

What it means

A transaction that reverts with the raw data 0x82b42900 hit the custom error Unauthorized, defined in Common DeFi convention. The explorer shows the hex because it does not have the contract's ABI to translate it.

A generic permission gate: the calling address is not allowed to do this. The custom-error cousin of owner and role checks.

How to fix it

Use the dapp's intended flow for the action. If you should have permission, confirm you are signing from the right address.
