Calldata
Definition: Calldata is the read-only byte data attached to an Ethereum transaction call, commonly encoding a smart-contract function and its arguments.
A simple ETH transfer can have empty calldata, while dApp interactions may contain complex encoded instructions.
How this concept appears in Terenval Wallet
When Terenval signs a contract interaction requested by a dApp, the transaction can include calldata describing the requested call.
Important: If a wallet cannot clearly explain complex calldata, treat the signature request cautiously.
