# Documentation Home

BIFY provides two distinct products:

* **BIFY Commerce** enables businesses to add stablecoin checkout, verifiable purchase records, certificates, access, rewards, and engagement features to their existing websites.
* **BIFY RWA** provides a regulated workflow for issuers and eligible investors purchasing and holding tokenized real-world asset units.

The products have separate contracts, APIs, portals, operating procedures, and documentation. The **BIFY SDK** belongs exclusively to BIFY Commerce.

## Documentation Principles

* Partners retain ownership of their Commerce catalogue, prices, inventory, order system, customer relationship, and fulfilment process.
* BIFY Commerce records the payment and digital ownership layer without requiring a partner storefront to implement blockchain infrastructure.
* BIFY RWA is a separate product with issuer approval, investor eligibility, offering controls, ERC-3643 tokenization, and issuer-defined redemption terms.
* Certificates are digital records. They do not independently transfer physical or legal title.

# 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://bify.gitbook.io/rwa-docs/start-here/readme.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.
