anybody can participate by "proving their ETH". Participants will send ETH to the designated smart contract, which will then register the ETH wallet used in the submission process with an AUT stake proportional to the the ETH submitted. The ETH will then be refunded less the transaction gas cost
the amount of ETH send is relevant or is just to "proving their ETH" ?
Understood now , we do have to sent the eth to the dev , is better to use an escrow in this case ...
