Here is an example demonstrating how it works:

For example The extra bonus for Vesting Swap is 2% (The bonus rate is constantly changing based on our market making performance and market volatility.) The lockup period is 7 days and each epoch time is 6 hours, which means there will be 28 epochs in total The ALT token price is 0.1 USDT.

A user uses 100 USDT to purchase ALT via the Vesting Swap Function with the 2% extra bonus. The total expected tokens received will be: USDT * (1+ Extra Bonus) / TokenPrice: 100 * (1.02) / 0.1c = 1020 ALT.

1020 ALT will be released to the user across the lockup period: 7 days. There will be a total of 28 epochs for the next 7 days. Each epoch time is 6 hours. The user will be receiving around 36.43 ALT per epoch, which means around 145.714 tokens a day for the next 7 days.

Note* Once you have swapped the APT for the discounted ALT using the Vesting Swap Function, the APT will become the protocol own liquidity - stabilising the protocol.
