xDollar is a multi-chain interest free lending platform that users can borrow non-custodial stablecoin, xUSD against their crypto assets on any side chains with a minimum collateral ratio. xDollar’s is here to democratize the store value of crypto assets on all chains with more utilization.
To begin our multichain planet exploration, xDollar starts with the Polygon and will eventually expand into other chains. Furthermore, we have designed a new tokenomics to support xDollar’s long-term vision.


xDollar’s vision is to become the next-generation DAO governance multi-collateral chain agnostic stablecoin lending platform.


xDollar’s mission is to make cross-chain DeFI accessible to 1 billion users by 2030 through xCHAIN DeFI Alliance.

Core Feature (using Matic for elaboration as deployed in Polygon first):

  • By staking $MATIC or $AVAX, zero interest-fee stablecoin (xUSD) is minted to improve capital utilization.
  • Minimum collateral ratio of 110% — more efficient usage of deposited $MATIC or $AVAX
  • Automated operation— all operations are algorithmic and fully automated, and protocol parameters are set at time of contract deployment.
  • Directly redeemable — xUSD can be redeemed at face value for the underlying collateral at any time.
  • Fully decentralized — xDollar contracts have no admin keys and will be accessible via multiple interfaces hosted by different Frontend Operators, making it censorship resistant.
  • xDollar Token (XDO) holders can earn xUSD (Borrowing fee) and $MATIC (Redeem fee on Polygon) or $AVAX (Redeem fee on Avalanche)
