ERC20Revertable is a simple ERC20 token that allow to revert lost tokens to the sender.

Revert Conditions

• If the sender requested to revert the tokens to the sender, the sender needs to wait for 30 days to revert the tokens to the sender.
• If the recipient disputed on the revert once, the sender and any future sender can't revert the tokens to the sender.
• If the recipient is a contract, the sender can't revert the tokens.
• If the recipient ever used the tokens of that ERC20, i.e transferd/approved before, the sender can't revert the tokens to the sender.

Intended Use

• After a sender accidentally sends his tokens to a wrong address, the sender calls requestTransferRevert(address recipient) to revert the tokens to the sender.
• The recipient can dispute on the revert by calling disputeTransferRevert() if the recipient was a real person and never used that token yet before.
• The sender has to wait 30 days to allow the recipient to dispute at anytime.
• After this period the sender can call transferRevert(address recipient) to revert the tokens to the sender. which eventually will check if the recipient disputed or not.
