State

directors

mapping (address => Boardseat) private directors;
​
struct Boardseat {
    uint256 appointmentTime;
    uint256 shares;
}

A map that records the current state of Basis Share stakers.

• address is the Share staker's address.

• appointmentTime is the block timestamp of last (deposit / withdrawal / dividend claim) of an account.

• shares is the account's current number of shares staked.

boardHistory

BoardSnapshot[] private boardHistory
​
struct BoardSnapshot {
    uint256 timestamp;
    uint256 rewardReceived;
    uint256 totalShares;
}

An array that records the history of past seigniorage events. This array is used to calculate the amount of dividends that a specific Share holder has accrued. New elements are added to boardHistory whenever Basis Cash is newly minted to the Boardroom contract.

• timestamp is the block timestamp when new seigniorage was added.

• rewardReceived is the amount of Basis Cash seigniorage that was newly added.

• totalShares is the total number of staked shares at the time of seigniorage generation.

Staked

event Staked(address indexed user, uint256 amount);

Emitted when Shares are staked via stake.

Withdrawn

event Withdrawn(address indexed user, uint256 amount);

Emitted when staked Shares are withdrawn via withdraw.

RewardPaid

event RewardPaid(address indexed user, uint256 reward);

Emitted when Share dividends are paid via claimDividends.

RewardAdded

event RewardAdded(uint256 reward);
