Proof of Concept (PoC) File
In packages/contracts/contracts/illuminex/xengine/chains/btc/AllowedRelayers.sol:
abstract contract AllowedRelayers is Ownable {
Ownable is used instead of Ownable2Step.
Revised Code File (Optional)
It is a best practice to use two-step ownership transfer pattern, meaning ownership transfer gets to a "pending" state and the new owner should claim his new rights, otherwise the old owner still has control of the contract. Consider using OpenZeppelin's Ownable2Step contract.
