Full Definition
Cross-chain refers to the interoperability between two or more blockchain networks, enabling the transfer of assets, data, or messages across them. Cross-chain technology is essential for multi-chain payment acceptance — it allows a merchant to accept payment from any supported blockchain regardless of which chain is used for settlement. Cross-chain swaps, bridges, and messaging protocols like LayerZero and Wormhole enable this functionality. SpacePay supports payments across multiple blockchain networks.
