Is it possible to revert a transaction in a blockchain?
Once a transaction is written to the blockchain (i.e., it has received at least one confirmation), no one can reverse it (revert). Neither the sender, nor the recipient, nor the blockchain validator (node runner).
In Tron blockchain (TRC20), for example, one confirmation takes ~20 seconds after the sender initiates the transaction.
There are ways to cancel a transaction in bitcoin blockchain before it has not received any confirmation. I have also heard about ways to cancel seemingly with one confirmation in some blockchain, and the way is technically complicated.
If the transaction was executed in some bridge’s smart contract, you may send a request to the bridge service.
One more tip is to check service’s traffic volume on similarweb. com. Real bridges and cross-chain aggregators have a stable solid traffic volume through months.
