<h2 class="wp-block-heading">How Does the Stability Pool Work?</h2>



<p>The Stability Pool works in three steps:</p>



<h5 class="wp-block-heading"><strong>Step 1</strong></h5>



<p>In a liquidation, all of the PLS in the liquidated vault gets distributed to the stability providers.</p>



<figure class="wp-block-image size-full"><img loading="lazy" width="325px" height="183px" srcset="https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223325/PLS-Liquidation-Stability-Pool-375x183.webp 375w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223325/PLS-Liquidation-Stability-Pool-662x322.webp 662w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223325/PLS-Liquidation-Stability-Pool-768x374.webp 768w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223325/PLS-Liquidation-Stability-Pool.webp 688w"  sizes="(max-width: 425px) 150px, 450px" src="https://ll-blog-dev.s3.ap-southeast-2.amazonaws.com/wp-content/uploads/2023/05/11223325/PLS-Liquidation-Stability-Pool.webp" alt="PLS Liquidation Stability Pool" class="wp-image-2393"/></figure>



<h5 class="wp-block-heading"><strong>STEP 2</strong></h5>



<p>The Stability Pool pays back the amount of USDL owed by the vault.</p>



<figure class="wp-block-image size-full"><img loading="lazy" width="325px" height="183px" srcset="https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223522/USDL-PLS-Liquidations-Stability-Pool-375x183.webp 375w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223522/USDL-PLS-Liquidations-Stability-Pool-662x322.webp 662w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223522/USDL-PLS-Liquidations-Stability-Pool-768x374.webp 768w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223522/USDL-PLS-Liquidations-Stability-Pool.webp 688w"  sizes="(max-width: 425px) 150px, 450px" src="https://ll-blog-dev.s3.ap-southeast-2.amazonaws.com/wp-content/uploads/2023/05/11223522/USDL-PLS-Liquidations-Stability-Pool.webp" alt="USDL PLS Liquidations Stability Pool" class="wp-image-2394"/></figure>



<h5 class="wp-block-heading">STEP 3</h5>



<p>The system state reaches equilibrium as the un-collateralized vault is closed out.</p>



<figure class="wp-block-image size-full"><img loading="lazy" width="325px" height="183px" srcset="https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223725/Stability-Provided-375x183.webp 375w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223725/Stability-Provided-662x322.webp 662w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223725/Stability-Provided-768x374.webp 768w, https://d2ly46a6b1u3g6.cloudfront.net/wp-content/uploads/2023/05/11223725/Stability-Provided.webp 688w"  sizes="(max-width: 425px) 150px, 450px" src="https://ll-blog-dev.s3.ap-southeast-2.amazonaws.com/wp-content/uploads/2023/05/11223725/Stability-Provided.webp" alt="Stability Providers" class="wp-image-2395"/></figure>



<h2 class="wp-block-heading tablecontent">Benefits of Being a Stability Provider</h2>



<p>As a Stability Provider, you are supporting the health of the system, and for doing so you’re rewarded in the protocol’s native token, LOAN. Plus, you also receive Pulse (PLS) when liquidations happen. This is because, by depositing your USDL into the Stability Pool, you’re essentially agreeing to buy PLS (at a discount) from Vaults being liquidated.</p>



<p>When a liquidation occurs, USDL is taken from the Stability Pool and used to pay off the undercollateralized loan, and the collateral in the Vault (i.e. the PLS) is distributed proportionally amongst the Stability Providers. For example, if you own 10% of the Stability Pool, then you receive 10% of the PLS from liquidations, whenever they occur.</p>



<h2 class="wp-block-heading tablecontent">Can I Lose Money as a Stability Provider?</h2>



<p>Even though liquidations happen at a collateral ratio above 100% most of the time, in the unlikely event of a flash crash or an <a href="https://www.thecoinzone.com/blockchain/what-are-blockchain-oracles" target="_blank" rel="noreferrer noopener"><strong>oracle</strong></a> failure, it is theoretically possible that a Vault could get liquidated below 100% collateralization. This would result in Stability Providers experiencing a loss since the collateral gain would be smaller than the reduction of their USDL deposit.</p>



<p>Note: In developing Liquid Loans, the team placed a great deal of importance on ensuring that the oracles used by the protocol are of the highest quality. Liquid Loans will have two oracles in place: </p>



<ol>
<li>Primary Oracle - <a href="https://fetchoracle.com/" target="_blank" rel="noreferrer noopener"><strong>Fet</strong></a><strong><a href="https://www.fetchoracle.com/" target="_blank" rel="noreferrer noopener">c</a></strong><a href="https://fetchoracle.com/" target="_blank" rel="noreferrer noopener"><strong>h</strong></a>: A <a href="https://www.thecoinzone.com/defi/decentralized-blockchain-oracles" target="_blank" rel="noreferrer noopener"><strong>decentralized blockchain oracle</strong></a> forked from <strong><a href="https://www.thecoinzone.com/blockchain/tellor-oracle" target="_blank" rel="noreferrer noopener">Tellor</a> </strong>and launched natively on PulseChain</li>



<li>Secondary Oracle: To Be Determined</li>
</ol>



<p>Put simply, the system is designed to reward Stability Providers, not harm them. For Stability Providers to make a loss, a dramatic “black swan” flash crash would have to happen, or all three oracles would have to fail simultaneously, which is extremely unlikely.</p>



<h2 class="wp-block-heading">What Influences Stability Pool APR?</h2>



<p>The Stability Pool APR fluctuates up and down for four different reasons:</p>



<ol>
<li>The Number of Liquidations</li>



<li>The Size of Each Liquidation</li>



<li>The Collateral Ratio at the Time of Liquidation</li>



<li>Early Adoption</li>
</ol>

<h2 class="wp-block-heading tablecontent">Can I Stake my USDL in the Stability Pool?</h2>



<p>No, but you can deposit it there, and you can stake your LOAN token in the Staking Pool!</p>



<p>From a user’s point of view, there’s not much difference between depositing your USDL into the Stability Pool and staking your LOAN in the Staking Pool – you simply click a button, and there’s no time lock like with HEX, for example – but it’s important that the correct terminology is used so that the two functions don’t get confused.</p>



<p>When you stake LOAN in the Staking Pool, you receive daily rewards in the form of USDL stablecoin from the system’s borrowing fees, and PLS from the system’s redemption fees.</p>

The Stability Pool EXPLAINED

How Staking USDL Maintains System Solvency and Earns Yield

The stability pool maintains system solvency of the Liquid Loans protocol by ensuring that USDL is always backed by PLS.
