FAQ
How do I sign a transaction in the Bron Wallet (passkey/fingerprint/face)

a. First, to login to the platform you can use your passkey, which can be your phone, browser, or password manager. This will allow you to view the Wallet dashboard.


b. To sign transactions, you then need to access your shard, which sits encrypted on your device. To decrypt your shard you can use your Device Key (protected by biometrics), which is bounded to your device and cannot be extracted. This signs the transaction and automatically re-encrypts the shard on your device.


c. All of this happens in the background. All you will have to do is click ‘Sign Transaction’ and authenticate with their Device Key.


d. This unique layer of security helps prevent unauthorised access to your digital assets, even in the event your machine is hacked and controlled remotely. Without your biometric authorisation, no transaction can be signed

What are Bron Guardians?

a. Your Bron Guardians are people you appoint who can help you restore access to your wallet in the event of a disaster.


b. You name two people you trust to act as Bron Guardians. They don’t have to know each other, and they won’t know a single detail about what’s inside your Bron wallet.


c. In the event you lose your device and all access to the assets in your Bron wallet, your nominated guardians can help authenticate you to Bron and Qrypt, re-establishing access to your wallet.


d. Guardians cannot work together or alone to gain access to your wallet. They can only help you prove who you say you are so that your shard can be regenerated.

How do cross-chain swaps work?

a. Cross-chain swaps are executed via an independent Smart Contract called an Intent. It works like a notice board on the blockchain. You post your intent to swap one asset for another, like an on-chain RFQ (request for quote).


b. Then third-party Solvers will come along and bid in an auction to fulfil your intent at the lowest price. Solvers act as a liquidity providers and compete to offer the best price to the user who initiated the swap. Anyone can be a Solver provided they comply with the requirements of the smart contract.


c. The user then accepts the price and the on-chain transaction begins. First the user will sign the transaction in their Bron Wallet, which sends their assets to the Solver. The Solver will then return the other side of the swap to the user. The Solver is required to post collateral to the Smart Contract in order to bid for the swap in the first place. They can only solve intents up to the value of the collateral that’s been posted. And if they fail to return the swapped asset within a specified period of time, the Smart Contract will automatically send the collateral to the user who initiated the swap.

What does a policy engine do?

a. Typically, a digital asset wallet acts as an interface between the user and the blockchain. It provides key management to authorise transactions.


b. The Bron Wallet is a much more sophisticated software layer that helps the user to organise their portfolio of digital assets before any on-chain activity can occur.


c. In essence, a Bron Wallet’s Policy Engine can be configured to set conditions which must be true before a transaction can be signed. There are innumerable ways to configure a Policy Engine, but commonly the conditions set out will govern who can create transactions, who can sign transactions, who can view or set user permission levels, etc…


d. These advanced features won’t be suitable for every user and are thus reserved for higher tiers. But for small trading firms such as family offices, they provide an essential layer of management and accountability.
