CBTC is a wrapped Bitcoin (1:1 backed) on the Canton network, designed for institutional use cases. It's built by BitSafe (makers of iBTC) and will support liquidity provision, and integration with derivatives marketplaces (e.g., the Canton-QCP collaboration). It's privacy-enabled and secure, using Schnorr/FROST and Taproot-based signatures along with a decentralized network of Attestors for the bridge. #### Do I need a Canton validator to participate? Yes, you need to have a live validator and a validator address on Canton mainnet to receive credentials #### What are the transaction fees? Current transaction fees are 5 basis points for minting/burning and 3 basis points for transferring/locking/unlocking #### Who operates the CBTC bridge nodes? 9 pre-screened external node operators (e.g., P2P, Everstake) with more than $1B in AUM and 1 BitSafe node, run both Bitcoin and Canton nodes #### Do I need special wallets? **Bitcoin side:** No special setup required - any wallet that can send BTC to a Taproot address (e.g., Sparrow, Ledger Live, BlueWallet) will work when you deposit into the bridge. **For Canton:** Yes. After your Bitcoin is bridged, CBTC lives on Canton, so you’ll need a wallet that understands Canton tokens. Today that list is short - the Canton CLI is fully supported, with additional wallets coming as the ecosystem matures. #### Are there any KYC/KYB requirements? No additional KYC/KYB is required between app creators because acceptance into Canton requires sponsorship by a Supervalidator #### Will running a CBTC Attestor Node make me a custodian of customer assets or allow me to sweep or transact against customer funds? Running an Attestor Node does **NOT** make you a custodian of any CBTC assets Here's what Attestor Nodes actually do: * Verify Bitcoin transactions and CBTC mint/burn operations * Participate in Canton's governance system as a "signing party" * Submit confirmations for deposits and withdrawals through automated processes * Help maintain the decentralized security of the CBTC network What Attestor Nodes do **NOT** do: * Hold or custody any CBTC tokens * Store customer private keys * Control any customer assets **The key distinction:** Attestors verify transactions; they don't custody assets. You can participate in the CBTC rewards system without any of the custodial concerns. #### What future opportunities are available? Following are some of the future opportunities with Canton and CBTC: * **Node operator rewards:** As a validator securing CBTC, you'll earn additional rewards from minting activity * **Customer minting:** You can potentially mint CBTC on behalf of customers, earning Canton coin rewards to share with them * **Utility-based rewards:** Canton is shifting toward rewarding apps that create actual trading and financial activity, which should benefit CBTC holders #### What if I have more questions?
