After the Ethereum merge, the block confirmation rules have changed. When the transaction is included in enough blocks, its status changes to Safe. Safe blocks mean that they are unlikely to be changed, but are not final. After a block has been included to a finalized epoch, its status becomes Finalized. Finalized transactions cannot be reverted without slashing the validators that accepted it, and are even less likely to be reverted without a hard fork. ChangeHero accepts transactions that have been included in a finalized block. Average epoch time is 7 minutes, so transactions with ETH/ERC-20 tokens normally should be approved within that time frame.
