The user’s Bitcoin address is mapped to their ETH address for the transaction, and the user will have 60 minutes to send the funds to the generated address at the custodian; otherwise, the transaction will be canceled, and the mapped address will no longer be valid. This Bitcoin deposit validation/tokenization system is termed the Proxy Relay. The Proxy relay confirms all BTC blocks onto the Matic chain to detect and validate any deposits with the mapped ETH wallet address. The confirmation of the deposit of BTC is confirmed onto the Matic Chain which instructs the smart contract to mint the corresponding amount of BTCpx onto either MRC20 or ERC20 version.
