The smart contracts for the Polymath Network token (POLY) crowdsale.
POLY tokens are used to grow and interact with the Polymath Security Token network, and also to pay for new security token issuances.
Please see the contracts/ directory.
The PolyMathToken.sol contract should be deployed first with the address of the presale wallet in the contructor. The 150million presale tokens will be stored in the presale wallet and the remaining 850million tokens will be stored in the address which deployed the contract.
Next, the PolyMathTokenOffering.sol contract is deployed. Parameters will be set by admin in the constructor.
After deploying this contract you must call the setOwner function of the deployed PolyMathToken.sol contract and give it the address of the PolyMathTokenOffering.sol contract. This will allow the crowdsale to transfer tokens even though they are locked until the end of the crowdsale for contributors.
Calling this function will pause all tokens from being transferred (other than by the crowdsale) until the crowdsale has been finalized. The function will also transfer the 150million tokens allocated for the public sale to the crowdsale contract to be sold. The deployer of PolyMathToken.sol will still hold the tokens which are to be vested.
Contributors must be whitelisted to contribute to the crowdsale. In order for KYC checks to be applied, contributors will first need to go through submitting their ID verification in order to be allowed to send ETH to the crowdsale contract.
The contract will automatically finalize when cap is reached, and purchases will automatically be blocked once the crowdsale end time is reached. Please note that someone must manually call the checkFinalize() function if the crowdsale end time is reached without hitting the cap. Calling that function will properly finalize the sale and allow tokens to be transferred by contributors.
Lastly, in order to achieve locking up future distribution of POLY tokens to founders, developers and advisors the PolyMathVesting.sol will be deployed.
Contracts are written in Solidity and tested using Truffle and testrpc.
