The replaceAdmin() function in HomeFi.sol updates admin role address in one-step. If an incorrect address is mistakenly used then future administrative access or even recovering from this mistake is prevented because all onlyAdmin modifier functions require _msg.sender to be the incorrectly used admin address (for which private keys may not be available to sign transactions). In such a case, contracts would have to be redeployed.
Suggest using a two-step process where the new admin address first claims ownership in one transaction and a second transaction from the new admin address takes ownership.
