Powercity Flex Protocol Review 2026: Interest-Free HEX Loans

Powercity Flex Protocol is a decentralized borrowing protocol on PulseChain. It lets holders of HEX take out interest-free loans in HEXDC, a USD-pegged stablecoin, without selling their HEX. It has a native token, FLEX, and has been tracked since July 2024.

It is part of Powercity, an ecosystem of projects built for PulseChain and linked through a central hub called the Core, which acts as the staking platform for the WATT token. Flex is the borrowing arm of that set of products.

The protocol holds roughly $196,000 in total value locked, with a 7-day increase of about 9.5%. That makes it a small niche protocol. The team, governance process and audit history are not published in any source we could cite, and no audits are listed.

Flex Protocol is a collateralized debt position (CDP) system. A user deposits HEX into a smart contract and borrows HEXDC against it. HEXDC is a stablecoin pegged to the US dollar, and the protocol states that these loans carry no interest.

Each position must stay above a 110% collateral ratio. That means the HEX locked must be worth at least 1.1 times the HEXDC borrowed. If HEX falls in price and the ratio drops below the minimum, the position can be liquidated under the protocol's rules, which generally means the collateral is sold or seized to cover the debt.

To close a loan, the borrower repays the HEXDC and withdraws their HEX. Because there is no interest, the main risk to a borrower is the collateral price falling, not the cost of carrying the debt.

The protocol describes its loans as interest-free, so there is no recurring interest on the HEXDC you borrow. That is the main cost advantage over lenders that charge a variable rate.

The protocol does not publish a full fee schedule in any source we can cite. Possible charges such as a one-time borrowing fee, redemption or liquidation penalties, and PulseChain gas costs would appear in the app before you confirm. Check them there first.

No audits are listed for Flex Protocol, and the team and governance details are not published in sources we could cite. Smart-contract risk is therefore unquantified. Borrowing protocols have a long record of exploits and oracle problems, and small ones with limited review are more exposed.

The main user-side risk is liquidation. A 110% minimum ratio leaves little room, and HEX is a volatile asset, so a sharp price drop can wipe out a position. The HEXDC stablecoin also depends on the protocol's mechanisms to hold its peg. Use small amounts, keep a wide buffer above the minimum, and verify the official app through the project's verified channels.

Flex Protocol is for existing HEX holders on PulseChain who are comfortable with CDP mechanics, liquidation risk and unaudited contracts. It is not suited to beginners, or to anyone who cannot actively monitor their collateral ratio.
