If you have already granted approval for this token in the past, this step will be automatically skipped during the minting process.

#### **Confirming the Mint transaction in wallet**

After a successful approval, the popup will mark the approval step as complete and move to the mint transaction confirmation step. Please click “Confirm” to finalize the vBTC on-chain minting process.
