JSON File for Fund Recoveries

It’s important to keep this JSON file until you have successfully initiated tBTC minting.
This file contains your BTC recovery address, the wallet's public key, the refund public key, and the refund lock time of this deposit. It can be used to reconstruct the deposit address in case of system error.
Each new deposit will generate a new JSON file. Take note: Recovery time lock is currently 9 months.
