# 5.1	Smart Contract based FingeRate Protocol

FingeRate’s Native token (ERC-20\[1]) MSOT & NFT token (ERC-721\[2]) SOT both have its respective smart contracts deployed in the Ethereum main net. Deploying on the Ethereum ensures scalability as we expand our business in the future. Besides, the SoT Renting Smart Contract tackles the survey requests autonomously until the delivery of the survey results and the Profit Distribution Smart Contract distributes the share of the profit generated by the SOTs to the SOT owners. These smart contracts combined forms the FingeRate Protocol.

\[1] ERC-20 is the standard for Fungible Tokens on the Ethereum Main net.

\[2] ERC721 is the standard for Non-Fungible Tokens on the Ethereum Main net.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://fingerate.gitbook.io/fingerate-whitepaper-v3.1/5.-technology/5.1-smart-contract-based-fingerate-protocol.md?ask=<question>&goal=<endgoal>
```

`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.
