Pool

It is the struct to manage project pools in funding cycle. Pool struct keeps to save the project's status.

struct Pool {
    uint id;
    address owner;
    string poolInfoUrl;
    string logoUrl;

    ////////////// Pool information

    // uint64 bidStartTime;
    uint64 bidEndTime;
        
    bool accessType;

    //token
    address tokenAddress;
    uint tokenPrice;
    uint tokenPriceDecimals;
    uint tokenTotalSupply;
    uint totalRaised;
    uint claimed;
    bool issued;
    bool allowed;
    bool removed;
    bool completed;

    //tier system
    uint[8] priceRangeEveryTier; // token
    uint[9] targetAmountEveryTier; // MEIJI
    uint[9] investedAmountEveryTier; // MEIJI
}

Functions

addPool

function addPool(string memory poolInfoUrl, string memory logoUrl) external

poolInfoUrl: Url to point the metadata including project application details logoUrl: Url to point logo file

issueToken

function issueToken(uint poolId) public onlyPoolOwner(poolId) validPoolId(poolId)

poolId: Identifier of project pool

modifyPoolInfo

modifyPoolInfo(uint poolId, address tokenAddress, uint tokenPrice, uint tokenDecimals, uint256 tokenTotalSupply, uint64 bidEndTime, uint[8] memory tier) public onlyPoolOwner(poolId) validPoolId(poolId)

poolId: Identifier of project pool tokenAddress: Project ticket token address tokenPrice: Ratio between $MEIJI and ticket token. it shows how many tickets can receive per $MEIJI. tokenDecimals: Project ticket token's decimal tokenTotalSupply: Total ticket amount for funding target. So funding target can be calculated as tokenTotalSupply / tokenPrice. bidEndTime: When the pool moves to the "completed pools" tier: Maximum $MEIJI amount array for 8 tier levels

bid

function bid(uint poolId, uint amount) external validPoolId(poolId)

poolId: Identifier of project pool amount: $MEIJI amount to deposit

claim

function claim(uint poolId) public validPoolId(poolId) onlyPoolOwner(poolId)

poolId: Identifier of project pool

unclaimedTickets

function unclaimedTickets(address investor, uint poolId) external view validPoolId(poolId) returns(uint)

investor: Wallet address of $MEIJI holder/staker poolId: Identifier of project pool

claimTickets

function claimTickets(uint poolId) public validPoolId(poolId)

poolId: Identifier of project pool

getTierLevel

function getTierLevel(uint256 poolId, address user) public view returns(uint)

poolId: Identifier of project pool user: Wallet address of user

setPools

function setPools(address pool1, address pool2, address pool3, address pool4, address pool5) private onlyOwner

pool1: 7 days lock staking pool address pool2: 14 days lock staking pool address pool3: 30 days lock staking pool address pool4: 60 days lock staking pool address pool5: 90 days lock staking pool address
