Smart-contracts description

There is a special function to return 3rd party tokens that were sent by mistake (function retrieveTokens()).
Each stage has a direct minting function in wei. This is made to support the external payment gateways.

Contracts contains

1. Token
2. Stage 1
3. Stage 2
4. Configurator - contract with main configuration for production

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 tokens by calling mintTokensByETHExternal and mintTokensExternal.

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.
