# Protocol Controls & Security

ADAPT I LP offers on-chain investors direct exposure to US Treasury Bill Yields by managing the Fund on TrueFi's modular blockchain infrastructure. Investors receive tfBILL tokens when they deposit USDC into the tfBILL Vault. These assets represent tokenized LP interests in ADAPT I LP.

## What is TrueFi?

TrueFi is a modular infrastructure for on-chain financial products. 

TrueFi connects investors, lenders, borrowers, and portfolio managers via smart contracts governed by the TRU Token.

Since its launch in November 2020, TrueFi has originated more than $1.7bn in loans to >30 borrowers and paid more than $40mm in interest to protocol participants.

Borrowers include both leading crypto-focused institutions and "real world" firms, such as fintech companies, trading firms, and credit funds.

## What are Asset Vaults? 

***Asset Vaults*** are TrueFi vaults that facilitate off-chain credit, or "Real World Asset" (RWA), activity.

## Why are Asset Vaults useful? 

Asset Vaults represent off-chain instruments by using on-chain attestations, or Asset *Reports.*

By using this structure, Asset Vaults can facilitate diverse and complex RWA activities, such as:

* *Deploy capital to off-chain uses:* portfolio managers (PMs) can use Asset Vaults to create representations of off-chain financial instruments.

## How do Asset Vaults work? 

Asset Vaults are TrueFi smart contracts that coordinate the subscription, redemption, and management of on-chain funds. 

Asset Vaults are made up of modular components, enabling PMs to configure vaults to their unique needs.

On TrueFi, Portfolio managers disburse funds using on-chain asset reports, rather than disbursing funds to on-chain loans.

### Tutorial / Demo

Users can test Asset Vaults by creating their own demo vault on Optimism Goerli using this [link](https://app.truefi.io/structured-asset-vault/create/). 

{% hint style="warning" %}
Before beginning, you will need to switch to the Optimism Goerli test network and ensure your wallet is funded with test ETH and test USDC assets.
