At launch :
Max transaction : 10000000000
Max wallet : 20000000000 ( Per address,you can use multiple addresses)
5% liquidity Fee on buying and selling QUEST
There is no dev or marketing fee.
QUEST is a social experiment style of token.
All you need to do is buy and share/shill/promote or simply talk about it.
Your Xs will depend on how much you shill.
There is no team or dev behind the project. We will act simply as holders.
There are no socials sites for the token,community is free to make one.

Synthetic Loot
This contract creates a "virtual NFT" of Loot based
on a given wallet address.
Because the wallet address is used as the deterministic
seed, there can only be one Loot bag per wallet.
Because it's not a real NFT, there is no
minting, transferability, etc.
Creators building on top of Loot can choose to recognize
Synthetic Loot as a way to allow a wider range of
adventurers to participate in the ecosystem, while
still being able to differentiate between
"original" Loot and Synthetic Loot.
Anyone with an Ethereum wallet has Synthetic Loot.
-----
Also optionally returns data in LootComponents format:
Call weaponComponents(), chestComponents(), etc. to get
an array of attributes that correspond to the item.
The return format is:
uint256[5] =>
[0] = Item ID
[1] = Suffix ID (0 for none)
[2] = Name Prefix ID (0 for none)
[3] = Name Suffix ID (0 for none)
[4] = Augmentation (0 = false, 1 = true)
See the item and attribute tables below for corresponding IDs.
The original LootComponents contract is at address:
0x3eb43b1545a360d1D065CB7539339363dFD445F3

In Attack on Titan, the Survey Corps (調査兵団) was the branch of the Military most actively involved in direct Titan combat, Titan study, human expansion, and outside exploration.
In this cryptocurrency driven world, Survey Corp Inu would be the investigation unit to monitor each and every project on the market. We mainly consist of 2 branches. The investment unit and military unit.
Our investment unit will locate nice and creative projects and use the investment pool fund to invest into all the nice projects. All the profits we gain will be fairly distributed to every holder through reflection and community rewards.
Our military unit aims to destroy and stop all the scammers and ruggers in the market in order to make this crypto currency world clean again. We will work as a team, corporate and gather all the information just like the survey corp in Attack of Titan.
