source venv/bin/activate

or to explicitly install Python 3.6 via

virtualenv -p /usr/local/bin/python3.6 venv
source venv/bin/activate

Running contract


How this works

After the contract is deployed, the Spotcoin forces users to go through a KYC process on, and they will be generated a deposit address that Spotcoin manages after passing KYC. This address will be whitelisted in our contract via the tokensale_register method.

Upon contribution on our site via USD, BTC, ETH, GAS, etc., we call the airdrop function to reserve X amount of SPOT tokens for that address given the current market rates, which are calculated on our backend.

The contract will ensure that this happens within the ICO period and the user is limited to getting a maximum of 1 million SPOT for public contributions.

After the ICO period has ended, we (the contract owner) will call mint_team - which will create team tokens, in order to maintain the 2-1 ratio of public-to-team tokens.
