The expedition page displays multiple ways to spend or stake ZOO tokens to obtain a "Chest". There are two types of chests: Gold and Silver.
No matter how you manage to obtain it, a gold chest will always contain an NFT Booster.
A silver chest, however, will have a 1 in 10 chance of winning an NFT Booster. If you get "nothing" 9 times in a row, the next purchase will give you a 100% chance to acquire an NFT Booster. A countdown of the current number of attempts left is displayed on the Silver chest itself.
NFT are distributed randomly between chests but the rarest NFTs can only be found in Gold chests.
The option to purchase chests is self-explanatory. You can buy one of either at a time. If an NFT Booster is awarded (remember, silver has a 1 in 10 chance), purchasing will automatically open and add the NFT Booster card to "My Safe".
The alternative option to obtain an NFT Booster is by locking up your ZOO tokens for a set amount of time:
- 2 Days
- 7 Days (Silver chest only)
- 15 Days
- 30 Days
Staking is possible in all 4 pools (2,7,15,30 day) at the same time. It's not possible to stake multiple times in the same pool.
Once you have staked your ZOO tokens, a countdown timer will be visible, displaying the remaining time left until your ZOO is returned and you can claim the associated chest.
Chest prices are set dynamically with a decrease of 1% in price every hour (no chest purchase or ZOO staked for chest) and increase of 1% every time a chest is bought, or when ZOO tokens are staked for a chest (with the excpetion of 0,1% increase for Silver Chest staking).
1 Silver Chest costs 10 times less than a Gold Chest. To receive 1 Gold/Silver Chest from staking ZOO tokens:
- 2 days of lock = the amount of ZOO needed to stake is 10 times the current price of a Gold Chest
- 7 days of lock = the amount of ZOO needed to stake is 2.5 times the current price of a Silver Chest
- 15 days lock = the amount of ZOO needed to stake is the current price of 1 Gold Chest
- 30 days lock = the amount of ZOO needed to stake is 5 times the current price of a Silver Chest
