IronSwap & xUSD: Building Cross-Protocol Synergy for Polygon Stablecoins

Iron Finance
2 min readAug 2, 2021


Last week we announced a partnership and cross-integration of the PUSD stablecoin into the IronSwap ecosystem. This consisted of adding the PUSD-3pool pair (PUSD and USDC+USDT+DAI) to the IronSwap DEX, followed up with a 30-day PYQ liquidity incentive campaign by PolyQuity. This quickly attracted $1.5M in TVL and is currently fetching about 46% APY (at time of writing).

This integration has proven benefits for both protocols. Iron benefits from adding a quality stablecoin to its DEX, which will accrue trading fees and additional revenue for our governance stakers. Polyquity users benefit from having PUSD added to the DEX with the highest liquidity and lowest swap fees for stablecoin pairs on Polygon. Additionally, both projects benefit from community cross exposure.

We are proud to announce our latest partnership with the stablecoin project — xDollar!

xDollar is an interest-free stablecoin minting platform built upon Liquity protocol operating on Polygon. xDollar’s vision is to become the cross-chain non-custodial stablecoin minting platform with DAO governance and a multi-collateral vault system.

xDollar enables users to open troves and mint non-custodial stablecoin, xUSD against their collateral with a minimum collateral ratio of only 110%. This xUSD can be staked in the stability pool, or placed into a stablecoin LP position to earn yield in XDO governance tokens.

xUSD will also have a new incentivized pair with IronSwap LP coming soon at xDollar’s farms page!

Additional Partnerships

The Iron team is open to additional partnerships with other protocols and communities looking to grow their supply and daily volume. By integrating IronSwap, these projects will increase their overall stablecoin activity and use-case. List with Ironswap and tap into the significant liquidity stored in Iron’s protocol.

Ironswap aims to become the “go-to” DEX for all stablecoin swaps. Its high liquidity and extremely low swap fee make for extremely low slippage — making it a very positive user experience overall. As early as this week, IronFinance is aiming to onboard the sixth stablecoin onto IronSwap!
