TWAM • 
Time Weighted Asset Mints
A minting harness enabling time-weighted assets to determine minting prices.
How it works
Requirements: maxMintingAmount number of erc721 tokens are minted to the TWAM contract in advance.
For a given mint's allocationPeriod (let's use 24 hours), a given type of asset can be deposited into the twam contract. Note: during the allocationPeriod, the deposit token can be withdrawn.
Once the allocationPeriod ends, a cooldown period begins with a length of mintingStart - allocationEnd.
Note: the cooldown may be 0.
At the beginning of the minting period mintingStart, each erc721 can be minted at the price equal to (total allocated assets) / (maximum supply erc721 tokens) as long as it exceeds the minimumPrice.
If the minimumPrice is not reached, minting is prohibited, and nothing happens during the minting period.
If all tokens are minted at the end of the minting period, the session is completed.
Otherwise (when the minimumPrice isn't met or not all tokens are minted), one of three options are available:
- The TWAM process starts over again.
- Minting is enabled at the max{
resultPrice,minimumPrice}. - The session is ended.
This option is denoted as the session's rolloverOption.
