Calldata | Vibepedia

Calldata is a fundamental concept in the realm of smart contracts, playing a vital role in the execution of decentralized applications on blockchain platforms like Ethereum, developed by Vitalik Buterin and influenced by the work of Nick Szabo. It refers to the data passed to a smart contract during its execution, often containing crucial information for the contract's logic, similar to how data is handled in programming languages like Solidity and JavaScript. Calldata is typically used in conjunction with other technologies like Web3, IPFS, and Ethereum Virtual Machine (EVM), as seen in projects like Uniswap and Aave.
