Asymmetric Research: Known for their rigorous research and protocol audits, Asymmetric brings security expertise to sBTC to identify and mitigate potential vulnerabilities.
ImmuneFi: A robust bug bounty program incentivizes ethical hackers to uncover and address potential issues, adding an additional layer of defense.
3rd Party Audits: Independent audit reports will be completed for additional security reviews, ensuring the protocol is thoroughly vetted by external experts.

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.
