# System's Elements
## 1. **The token (G$)**
The ***GoodDollar token (G$)*** is an ERC-20, ERC-677, ERC-777 and a [**pure Supertoken**](https://superfluid.org/) (on celo) crypto token with a max supply of 2.2 trillion. It is native to Ethereum and also operates on Fuse and Celo.
## **2. The Reserve**
The ***GoodDollar Reserve*** is the smart contract that governs the vault holding the assets that back G$ tokens. The algorithm that guides the reserve is based on the Bancor formula, which has been altered to fit GoodDollar’s needs. There are two important characteristics unique to the GoodDollar Reserve:
1. The reserve supports the generation of G$. Users can always convert to and from G$ via the reserve.
2. The reserve applies an "exit contribution" to all G$ sold back to the reserve.
3. The unique math of the GoodDollar Reserve lends G$ exceptional stability.
## **4. Savings rewards**
Rewards are fixed at 5% APY.
## **5. Distribution Manager**
The **Distribution Manager** receives newly created G$ from the Reserve and distributes it.
This component acts as the **central allocator of G$ emissions**.
## **6. UBI Contract (UBIScheme)**
The ***UBIScheme*** is a smart contract that handles the distribution of G$ to all white-listed addresses.
The daily amount per claimer is calculated by:\
Daily Pool = G$ in pool divided by Cycle Days (60)\
Daily Claim = Daily Pool divided by previous day claimers \* 1.05 (5% buffer)
## **7. Governance (DAO)**
The GoodDollar governance model is based on the Compound governance model and code, as set out [here](https://compound.finance/docs/governance#comp). Critical to the process is the **GOOD token**, a non-transferable token that controls all smart contracts within the GoodDollar ecosystem.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.gooddollar.org/how-gooddollar-works/systems-elements.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
