What is the boton generate keys ?
thx
Info you get on that step will allow you to collect Lisk after the launch. If you lose the info, you lose your Lisk.
When you click Generate Keys the system generates an address, pass phrase to access this address and a public key.
ok i have an adress i don't click on correct ?
You need to generate keys (it generates a wallet address, a passphrase and a public key) for every exchange you committed.
Once the ICO is over, you will use those keys to access your wallet with the total LISK you bought.
