A cross-chain decentralized marketplace built on Push Chain, enabling users from any supported chain to buy, sell, and trade digital and physical assets seamlessly through Universal Entry Accounts (UEA).

The Universal Marketplace leverages the power of Push Chain's Universal Accounts to create a single, unified trading experience across multiple blockchains.
Users can list, discover, and purchase assets — all while maintaining chain-agnostic interoperability and secure ownership verification.

  Users connect once and interact across all supported chains.

• Cross-Chain Asset Listing:

• Event Emissions:
  Real-time event updates for listings, bids, and completed sales, indexed on Push Chain.

• Gas-Optimized Transactions:
  Smart batching reduces costs for cross-chain interactions.
