ERC20Revertable is a simple ERC20 token that allow to revert lost tokens to the sender.
- If the recipient never transfered the tokens of that ERC20 before, the sender can request to revert the tokens to the sender.
- 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.
- 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.
