# Protocols / project information provided by Unified

Every protocol / project essentially has total value locked (TVL) in the form of cryptocurrency assets staked on the protocol / project.

[DefiLlama](https://defillama.com/) provides a high-level overview of TVLs by protocol / project.

* Each protocol / project may have multiple liquidity pools / vaults within it.

In general, users stake cryptocurrency assets into liquidity pools / vaults, and expect to generate a return in the form of rewards or emissions. 

When users stake assets into liquidity pools / vaults, they receive a receipt for the deposit, often referred to as a Liquidity Provision (LP) token.

When rewards or emissions have a monetary value attached to them, this allows users to estimate the annual percentage return (APR) that they are receiving on that liquidity pool / vault.  

* The APR is a function of rewards / emissions (at current rate) over the total value of the liquidity pool / vault.
* While rewards / emissions may follow a schedule in which it changes over time, by convention, APR is measured based on the current rate of rewards / emissions.

[VFAT](https://vfat.tools/) provides a tool for users to view liquidity pools / vaults for many protocols / projects (but not exhaustive).

The most useful items of information for users are in the following table.

| What is the TVL of that particular liquidity pool / vault?  What is the user's share of the TVL of that particular liquidity pool / vault? | <p>These 2 measures are usually placed together, because they indicate a user's exposure risk to a protocol / project that may have very little adoption.</p><p></p><p>For example, a liquidity pool / vault may have high APR, but it could be due to low amount of total deposits by all users into that liquidity pool / vault. In this case, the high APR could signify that either users have been fleeing that liquidity pool / vault, or it could be a temporarily high APR because that liquidity pool / vault has not received much deposits yet.   If a user deposits into this liquidity pool / vault, that APR may quickly disappear as more adoption takes place.</p><p></p><p>As another example, if a user has a high percentage share of that vault, then that user carries a large exposure to that vault.  This may be relevant in case a user wants to manage their exposure relative to others.  The more risk is shared with others, there may be more eyes on that protocol / project to monitor it for incidences such as smart contract exploits.</p> |

The above 4 information items represent the information that each user should have on a particular liquidity pool / vault that they have participated in.  A user should not see liquidity pools / vaults that they have not participated in (as it is superfluous information).

{% hint style="info" %}
Sometimes protocol / project front-ends fail.  VFAT interacts directly with smart contracts and therefore provides 3 useful tools in addition to information:

* Users can stake directly into liquidity pools / vaults.
* Users can unstake directly from liquidity pools / vaults.  This is extremely useful when there is a critical issue involving liquidity pools / vaults and the front end is not available.
* Users can claim unclaimed rewards / emissions directly from liquidity pools / vaults.

This is possible because VFAT is based on users logging in via e.g. Metamask for a single address.
