Cross-Contract Gateway refers to a mechanism that enables seamless communication and interaction between different smart contracts on a blockchain. It facilitates transactions and data sharing across multiple contracts, allowing for more complex operations that involve diverse decentralized applications.By using cross-contract gateways, developers can create applications that leverage the functionalities of multiple contracts. This interoperability improves efficiency and opens up new possibilities for decentralized finance (DeFi), gaming, and other sectors, where multiple smart contracts may need to interact.For example, a gaming platform could use a cross-contract gateway to link a smart contract that manages in-game assets with another contract that handles user accounts. This connection allows for enhanced user experiences, such as instant trading of assets without requiring users to interact with each contract separately. Overall, cross-contract gateways enhance the capabilities of blockchain-based systems by breaking down silos and fostering a more integrated ecosystem.
