What Are Cross-chain Contract Calls? 

Cross-chain contract calls allow information, cryptocurrencies or NFTs, which would otherwise be constrained to their own network, to move freely between blockchains via smart contracts.

Cross-chain contract calls are a means of achieving interoperability in Web3. This enables users to have a smooth experience when interacting with any dApp regardless of the chain they’re on. 

Users must currently navigate manually between chains in order to manage assets while engaging with dApps via cross-chain bridges, which are complex and laborious. The objective of cross-chain contract calls is to remove the need for cumbersome processes of moving funds between different chains, using bridges and managing different native gas tokens. By abstracting cross-chain complexities, cross-chain contract calls improve Web3 UX and provide a chain-agnostic experience that feels chainless. The trustless and verifiable network connects users to other chains with the support of on-chain validators to create a decentralized network where burdensome obstacles are eliminated, allowing users to seamlessly interact with dApps.  

Use cases of cross-chain contract calls include NFT purchases, multi-chain yield farms and liquidity pools. In the case of NFTs, users can leverage SDKs to enable the movement of assets and purchase NFTs in an all-in-one transaction creating a seamless one-click NFT minting experience. For multi-chain yield farms and liquidity pools, cross-chain contract calls allow users to deposit liquidity into pools without having to bridge assets between networks.
