## **Unlocking Stellar Liquidity Across Blockchains**&#x20;

Polariz is Stellar's first cross-chain yield protocol, designed to unlock the full potential of $XLM liquidity. By minting the over-collateralized stablecoin $pUSD, users can access yield-generating opportunities across leading blockchain ecosystems without liquidating their $XLM holdings.

$pUSD serves as both an asset and a gateway, expanding Stellar liquidity to leading blockchain ecosystems. Unlock yield, earn, and access seamless interoperability with top DeFi dApps across different verticals including AMMs, lending protocols and perpetual DEXs.&#x20;

Presently, $XLM yield opportunities are limited to lending on Blend or using CEXs for an APY that doesn't exceed 3%. With Polariz, $pUSD holders will be able to tap into double-digits APY across protocols like Kamino or Aave.
