Reject // Auto-refund // Send-back functionality

[drhus]

To allow for seamless recovery of lost token sent to xdai.io (burner wallet) It would be great to have sort of "Reject" // Auto-refund functionality, in another word if you send anything to this burner address but xDAI the smart contract would transfer it back to the sender within n hrs

On front end user shall be notified, he should see sort of notification with x fund/tokens received with error (it's not xDAI) and maybe 1) click to refund immediately 2) export private key

Currently, a user sending n DAI instead of xDAI, wouldn't be able to recover it easily even with the private key, he would still need to send some small ETH to the address >> to be able to recover his funds, too much complexity..

Not exactly how this would work. The transfers work just like the Ethereum mainnet and there isn't currently a way to do this that I know of. Maybe I'm not understanding it correctly.

However, I think Zooko mentioned it would be a good idea to have funds automatically revert: https://twitter.com/zooko/status/1061689556787961856

I think the app itself could do this somehow since it is in control of the privatekey. (Similar to how it needs to automatically sweep back unused link funds).

Let's keep this discussion open and see if we can come up with a way to do this.
