This contract suite manages the distribution of shares from the makers fees inside LinkPool and manage our public share sale. Contributors can send link to this contract for % percentage share based on a 1000 ETH hard-cap valued at 25%.
- Hard Cap: 1000 ETH
- Valuation: 4000 ETH
- Minimum Stake: 0.2 ETH (0.005% of valuation)
- Total Share of Creators: 75%
Once contributed, the digital agreement is locked and you will recieve that share for the lifetime of LinkPool. Fees earned by the LinkPool platform are transfered to this suite.
This contract is token agnostic and can support management and distribution of any ERC20 token, but natively uses ERC677 (LINK).
There are four main events within the owners contract:
- Contribution
- Distribution of Tokens
- Token Withdrawal
- Ownership Transfer
Contribution is called by the fallback function.
Method Signature:
function contribute(address sender) internal payable;
Usage:
web3.eth.sendTransaction({
from: accounts[1],
to: PoolOwners.address,
value: web3.toWei(5, 'ether'),
gas: 100000
});Distribution of the token balance within the contract. Token address can be specified, allowing contract to be token agnostic.
Method Signature:
function distributeTokens(address token) public onlyPoolOwner();
Usage:
await poolOwners.distributeTokens(LinkToken.address, { from: accounts[1] });Withdrawal of token balance for a single owner to their own wallet.
Method Signature:
function withdrawTokens(address token, uint256 amount) public onlyPoolOwner();
Usage:
await poolOwners.withdrawTokens(LinkToken.address, ownerBalance, { from: accounts[1] });Allows an owner/contributor of LinkPool to transfer part or all of their ownership to a different address.
Method Signature:
function transferOwnership(address receiver, uint256 amount) public onlyPoolOwner();
Usage:
await poolOwners.transferOwnership(accounts[3], web3.toWei(500, 'ether'), { from: accounts[1] });Requires v8 of NodeJS or later.
