Anyone can create a pancake IFO-like pre-sale (there are soft caps and hard caps, part of the excess investment will be refunded, and the sales unit price will not be increased) 3. Supporting functions and pages, such as lockers (token locks), pre-sale lists, etc. 4. A swap, preferably based on uni v3, does not require the farm part 5. A simple treasury, the platform tokens can be used to exchange funds in the treasury, the total amount of platform tokens used for exchange will be destroyed, and the exchange ratio is based on the balance of the treasury / the remaining total amount of platform tokens = exchange ratio 6. There are some modifications to the pre-sale charging part, such as the allocation of creation fees and service fees (2% of the funds raised), part of which is given to the platform wallet and part to the treasury; if platform tokens are used to create a pre-sale, only the creation fee will be charged Fee, service charge free prior choice: 1. If you have developed a pre-sale platform and have product cases 2. There are additional functions that can be copied, such as creating tokens, tiered sales, or anti-bots, creating airdrops, etc., preferred 3. The contract uses solidity. It is better to host the front-end and back-end codes in netlify, which is more convenient. It is also acceptable to deploy on the server
