Token Sale

This is a smart contract running on NEAR Protocol. It could be used to run a token sale.

Sale rules

• There are 2 periods: Sale and Grace.
• In Sale period: users can deposit and withdraw.
• In Grace period: users can only withdraw.
• At any point of time, the price is calculated by the total deposit divided by the total number of tokens for sale.
• After the grace period ends, the sale finishes and the price is finalized.
• At that point, tokens are allocated to users based on their deposit. Users can redeem to their wallets.
