Swap BTC to CBTC on Bron

A Step-by-Step Visual Guide To BTC/CBTC swaps on Bron

Before You Begin

To ensure a smooth swapping experience, please make sure you have the following:

• Bron Wallet: Ensure you have the latest version of the Bron wallet installed on your device

• Sufficient BTC Balance: You will need enough BTC in your wallet to cover the amount you wish to swap, plus a small network fee

Important Notes

• Two-Step Signature Process: The swap requires two separate signatures. The first signature initiates the swap, and the second signature accepts the CBTC deposit

• Network Fees: A small network fee in BTC is required to process the transaction

• BronSwaps: Bron uses Intents-based swap functionality, which enables users to convert BTC to CTBC using a decentralised infrastructure. You send BTC, you receive CBTC. If any part of the transaction fails, the user gets compensated immediately by the Intents smart contract. No value lost. No counterparty risk. No bridge custody.

• Authentication: For security, you will be required to authenticate transactions using your preferred method. The screenshots in this guide use TouchID on an Apple desktop device but Bron allows you to create a passkey using your fingerprint, face, screen lock, or hardware security key and one-time passwords

Step-by-step guide

Set Up the Swap

Navigate to the Swap section in your Bron wallet, select the account you wish to use, and enter the amount of BTC you want to sell
