Treasury
As of April 2023, those contracts have not been deployed, and there is no front-end for this module.
Module Name: Treasury Module
Contract Sources:
Oracles
Summary
This module is a custom creation made of two smart contracts: The first one, the Kolektivo Treasury, holds the natural capital assets (or their indexes) and creates the Kolektivo Treasury Token (KTT) which directly represents the treasury’s value. KTT is a rebase token, influenced by Ampleforth. Through its elastic supply and the rebasing mechanics, the aim is to keep the token value close to a certain ratio. The treasury is comprised of the various LP index tokens as well as other currencies.
Module Details
The Treasury Module has 2 core components consisting of the Treasury.sol, and ElasticReceiptToken.sol contracts.
Treasury
The Treasury.sol contract allows to:
Hold multiple tokens: ERC20, Index/Liquidity Tokens from Balancer, Stable Coins such as cUSD or cEUR, ERC721, and GeoNFTs.
Withdraw certain tokens up to a certain amount (limited to certain addresses and revokable). For example: A mapping of address =>
address=>uint256, where we can define “Address X can withdraw Token Y up to a limit of 123”.Send treasury assets to arbitrary addresses. For example, the Treasury has stables and wants to fund a Kolektivo community economy.
Sell and buy assets (bond and redeem) by minting/burning the Kolektivo Treasury Token (KTT). This implies that the treasury allows to:
List certain tokens as bondable/redeemable
List certain tokens to be unbonded/unredeemed
Dynamically set the price of the bonds based on the value of assets to un-/bond. Note that the pricing should depend on the average value for some time to prevent flash loan attacks.
Perform negative and positive rebases
Modify the rebase impact by applying a damping factor to the supply delta (e.g. 1/5)
Create an elastic supply token (KTT).
Modify the deviation threshold defining supply boundaries in which no rebase should occur (e.g. 5%)

Treasury Token
The Treasury Token is a vanilla ERC-20 token backed by the Treasury's assets. It is called the Kolektivo Treasury Token (KTT), and it is an elastic / rebasing token, which means that 1 KTT is always worth 1$ worth of treasury assets. The KTT contract is inspired by the well-tested Ampleforth. Here are some of the token's characteristics:
The maximum supply is one billion.
Each rebase happens at an epoch.
Each time someone interacts with a token, e.g. token transfer, rebase is triggered a rebase.
Rebase can also be called manually.
