eth_call

POST

Invoke smart contract functions locally using eth_call for read-only queries without altering blockchain state. Essential for dApps to fetch data like balances or contract states via JSON-RPC.

The eth_call method is essential in the Ethereum JSON-RPC interface, enabling read-only interaction with smart contracts on the Ethereum blockchain. It allows for querying data, such as balances and contract states, without modifying the blockchain, unlike state-changing methods like eth_sendTransaction. As part of the Core API, eth_call is critical for building Web3 dApps.
