CollateralProvider
CollateralProvider is a contract that enables the management of tokens
and main coins
for the Project Owner.
Pools
When registering a pool, three types of pools are created for refund purposes.
Main Coin Pool
If a user withdraws their tokens before the end of the lock-up period, a portion of the main coins, based on the withdrawal amount and the defined rate, becomes accessible to the project owner. The main coin pool holds this portion and allows the withdrawal of main coins before the time limit expires.
Token Pool
In the event that some users initiate a refund, the tokens they exchange for main coins are sent to the token pool. The project owner has access to withdraw tokens from this pool before the finish time limit.
Refund Main Coin Pool
This pool holds an initial amount of main coins to facilitate the refund process. Users who wish to request a refund exchange their tokens for main coins, resulting in a decrease in the amount held in the Refund Main Coin pool and an increase in the Token pool. After the time limit, the project owner gains access to the Refund Main Coin pool.
Сollateral provider interacts with other providers to correctly calculate the required accrual amounts for Collector pools.
Rate To Wei
The poolIdToRateToWei
variable is a mapping within the CollateralProvider contract that associates each pool ID with a rate conversion factor from main coins to tokens. This mapping is crucial for calculating the exchange rate between the main coin (e.g., USDT) and the corresponding tokens within each pool.
mapping(uint256 => uint256) public poolIdToRateToWei;
- Key (uint256): Represents the unique identifier of a collateral pool (poolId).
- Value (uint256): Represents the rate conversion factor from main coins to tokens associated with the specified pool.
Example Usage
// Example values
// Updated example values in Wei
uint256 mainCoinAmount = 300 * 10**18; // Main coin amount, e.g., USDT in Wei
uint256 tokenAmount = 150 * 10**18; // Token amount in Wei
// Calculate exchange rate
uint256 rate = (mainCoinAmount * 1e21) / tokenAmount;
// Output the result
// rate = (300 * 1e21) / 150 = 2e18
In this case, the values for mainCoinAmount
and tokenAmount
are represented in Wei
(the smallest unit of ether). The resulting rate is 2*10**18
or 2e18
. The resulting rate indicates that for every 1 Wei
of the tokens, a user would receive 2e18 Wei
worth of main coins based on this exchange rate.
Conclusion
The CollateralProvider contract provides a comprehensive solution for managing tokens and main coins for the Project Owner. With its time-limited collateral pools, it ensures that funds are securely held until a specific time limit is reached. Once the time limit expires, the Project Owner gains full control over the Collector pools, enabling efficient fund withdrawal.
Contract creates three types of pools: the Main Coin Pool, Token Pool, and Refund Main Coin Pool. These pools facilitate the exchange and withdrawal of tokens and main coins based on user actions and the defined time limit. Users withdrawing tokens increase the Main Coin pool and decrease the Refund Main coin pool, while those who initiate a refund exchange tokens for main coins, which affects the Token pool and the Refund Main coin pool.
The CollateralProvider contract collaborates with other providers to accurately calculate the required accrual amounts for the Collector pools, ensuring transparency and reliability in fund management.
