A contract call refers to the process of executing a function or interacting with a smart contract on a blockchain. Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They run on platforms like Ethereum, allowing for automated and trustless transactions between parties.When a user or another contract makes a call to a smart contract, they are triggering specific functions defined in the contract’s code. This can involve various activities, such as transferring tokens, updating states, or executing complex logic. Contract calls help facilitate decentralized applications by allowing different components to communicate and interact seamlessly.The call can be categorized as either a “read” or “write” operation. A read operation retrieves data without altering the state of the blockchain, while a write operation changes the state and usually requires gas fees, which are paid in the native cryptocurrency of the platform. Overall, contract calls enable the functionality and versatility of decentralized applications and the broader blockchain ecosystem.
