FAQ 7

There are two transaction fees required to mint your sBTC. The first is set by the user manually when they initiate the deposit transaction within their wallet.
The second is a fee used to consolidate the deposit UTXOs into the single signer UTXO. This separate transaction fee happens automatically and is set to a max of 80k sats. This is automatically deducted from your minted sBTC. This is not a signer fee but a regular Bitcoin transaction fee.
