# Security and Attack Vectors

1. Gradual Fund Integration:

* When users deposit in Earn or sell ERC20s to MortgageFi, the contracts stream the funds over 3 days
* This prevents sudden large influxes of funds that could potentially exploit the system
* Implemented through the doUpdate function in the mortgagefipool contract

2. No Direct Lending of Deposited Stablecoins:

* Stablecoins from Earn users are not available for direct lending
* They are used exclusively to purchase ERC20s from sellers, maintaining system integrity

# Agent Instructions

## 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://mortgagefi-docs.gitbook.io/mortgagefi-documentation/mortgagefi-ecosystem/self-balancing-protocol/security-and-attack-vectors.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.
