PolyQuity Review 2026: Interest-Free PUSD Loans Against MATIC
PolyQuity is a small Polygon borrowing protocol that issues interest-free PUSD loans against MATIC collateral. It is an interesting design, but its low TVL and thin public information call for caution.

Our verdict on PolyQuity
5.0/10PolyQuity suits experienced DeFi users who want to borrow a USD stablecoin against MATIC without paying interest and who understand liquidation risk. Its main strength is the simple, interest-free model with a 110% minimum ratio and a layered backstop. The main caveat is scale and transparency: TVL is under $100,000, trading in the token is thin, and the team, auditors and borrowing fee are not published in the material reviewed. Size positions conservatively and verify documentation first.

What is PolyQuity?
PolyQuity is a decentralized borrowing protocol on Polygon. Users lock MATIC and draw loans in PUSD, a USD-pegged stablecoin, with no interest charged on the debt. Loans must keep a minimum collateral ratio of 110%.
It sits in the collateralized debt position category. The pitch is capital efficiency and simplicity: one collateral type, one stablecoin and a backstop built from a Stability Pool and the borrowers themselves.
Scale is modest. The protocol shows around $93,600 in total value locked, and the PYQ token sees very little trading. Two audits are listed, but the auditors and the team behind the project are not named in the material reviewed.
How PolyQuity works
A user deposits MATIC into the protocol and borrows PUSD against it. The loan carries no interest, but the position must always hold collateral worth at least 110% of the debt. A user who borrows less keeps a larger safety margin.
If a position falls below the minimum ratio, it can be liquidated. The first line of defense is the Stability Pool, which holds PUSD from depositors and uses it to absorb the debt of liquidated loans, with the depositors receiving the seized collateral. If the pool is not enough, other borrowers collectively act as the guarantor of last resort.
The repayment path is simple: return the PUSD debt to unlock the MATIC collateral. Because the system relies on one volatile collateral asset, price drops are the main stress point.

Key features
01
Interest-free loans
Loans carry no ongoing interest rate, which sets it apart from lending markets that charge variable rates.
02
MATIC-backed borrowing
Borrowers deposit MATIC on Polygon and draw PUSD against it, keeping exposure to their collateral.
03
PUSD stablecoin
PUSD is a USD-pegged stablecoin issued by the protocol when loans are opened.
04
110% minimum ratio
Each loan must stay above a 110% collateral ratio, which allows relatively high capital efficiency.
05
Stability Pool
A pool of PUSD absorbs liquidated debt and acts as a first backstop for the system.
06
Collective backstop
Other borrowers collectively act as guarantors of last resort if the Stability Pool cannot cover bad debt.
Pros and cons
What we like
- Interest-free loans with no recurring rate on PUSD debt
- Low 110% minimum collateral ratio gives high capital efficiency
- Layered backstop with a Stability Pool and collective borrower guarantee
- Runs on Polygon, where transaction costs are generally low
- Two audits are listed for the protocol
Watch out for
- Very small TVL of roughly $93,600, so the protocol has little capital behind it
- Only MATIC is described as collateral, so users are exposed to one volatile asset
- A 110% minimum collateral ratio leaves little buffer in a fast price drop
- The stablecoin peg depends on the mechanism working at low liquidity
- The team, audit firms and borrowing fee are not published in the material reviewed
- Market data suggests very thin trading activity for the PYQ token
PolyQuity fees
The protocol describes its loans as interest-free, so borrowers do not pay a recurring rate on PUSD debt. That is the main cost advantage described.
The material reviewed does not state any one-time borrowing fee, redemption fee or other protocol charges. Users also pay Polygon network gas on each transaction. Fee details should be in the protocol's documentation and on the app before a loan is opened.
Is PolyQuity safe?
Two audits are listed for the protocol, but the auditors, dates and findings are not detailed in the material reviewed. The team and any bug bounty are also not described. Users should check the documentation for the audit reports before depositing funds.
Main risks are smart-contract bugs, MATIC price drops that trigger liquidation at a 110% ratio, and a PUSD peg that may weaken when liquidity is thin. With TVL under $100,000, there is little capital to absorb a stress event. Treat this as a high-risk position and only commit what you can afford to lose.
6 steps
How to get started with PolyQuity
- 1
Read the protocol's documentation to understand liquidation and the Stability Pool.
- 2
Set up a Polygon-compatible wallet and fund it with MATIC for collateral and gas.
- 3
Connect the wallet to the official PolyQuity app, confirming the address from the project's verified channels.
- 4
Open a position by depositing MATIC and choosing a PUSD borrow amount well above the 110% minimum ratio.
- 5
Check any borrowing fee shown before confirming the transaction.
- 6
Monitor your collateral ratio and add collateral or repay PUSD if MATIC falls.
Who PolyQuity is for
PolyQuity is for experienced Polygon users who hold MATIC, want stablecoin liquidity without selling it, and can monitor collateral ratios actively. It is not suited to beginners or anyone who needs a deeply liquid, established protocol.
PolyQuity FAQs
What is PolyQuity?
PolyQuity is a decentralized borrowing protocol on Polygon. Users lock MATIC as collateral and draw loans in PUSD, a USD-pegged stablecoin, without paying interest.
What is the minimum collateral ratio on PolyQuity?
The minimum collateral ratio is 110%. If a position's collateral value falls below that level relative to its debt, it can be liquidated.
Does PolyQuity charge interest?
Loans are described as interest-free. Any one-time borrowing or redemption fee is not stated in the material reviewed, so check the protocol's documentation before opening a position.
What is PUSD?
PUSD is the USD-pegged stablecoin that borrowers receive when they take a loan. It is backed by MATIC collateral held in the protocol.
What is the PYQ token?
PYQ is the protocol's token. Its specific utility is not detailed in the material reviewed, so read the project's documentation before buying it.
Is PolyQuity safe?
Like any smart-contract borrowing protocol, it carries risk. TVL is small, collateral is volatile, and liquidation is possible if MATIC drops. Two audits are listed, but the auditors and findings are not detailed here, so treat it as high risk.
