How to manage contract

To start working with contract you should follow next steps:

  1. Compile it in Remix with enamble optimization flag and compiler 0.4.18
  2. Deploy bytecode with MyEtherWallet. Gas 5100000 (actually 5073514).
  3. Call 'deploy' function on addres from (3). Gas 4000000 (actually 3979551).

Contract manager must call finishMinting after each crowdsale milestone! To support external mint service manager should specify address by calling setDirectMintAgent. After that specified address can direct mint VST tokens by calling directMint.

How to invest

To purchase tokens investor should send ETH (more than minimum 0.1 ETH) to corresponding crowdsale contract. Recommended GAS: 250000, GAS PRICE - 21 Gwei.
