# DeFi Integrations

> Use trUSD and strUSD across the DeFi ecosystem

## Overview

trUSD and strUSD are standard ERC-20 tokens, so they work anywhere ERC-20s do. The live catalog of venues, with current rates, is in the app at [app.tori.finance/defi](https://app.tori.finance/defi).

## Ecosystem Vault

The Tori Ecosystem Vault (LP token: etrUSD) runs on Upshift and is curated by RockawayX, which publishes its own [investment thesis and risk disclosure](https://www.rockawayx.com/insights/rockawayx-tori-ecosystem-vault-investment-thesis-risk-disclosure) for the vault. Phase details are on the [Pre-Deposit Vault](/resources/pre-deposit) page.

## Composability

strUSD is built to be used as:

* **Collateral**: borrow against it in lending protocols
* **Liquidity**: provide it to pools
* **Yield exposure**: access fixed or variable yield through third-party markets

<Note>
  Using strUSD as collateral or in leveraged strategies involves additional risks including liquidation risk. Understand all risks before proceeding. See [Risk Disclosures](/resources/risks).
