The eth_call method in Ronin's JSON-RPC API is used to execute a new message call immediately without creating a transaction on the blockchain. This method is particularly useful for testing and debugging smart contracts, as it allows developers to simulate the execution of contract methods without actually sending transactions to the network. This can help in identifying issues or understanding the behavior of contracts without incurring any gas costs or affecting the blockchain state. Please check the common use cases:
Testing Smart Contracts: Before deploying a smart contract, developers can use eth_call to test its functionality and ensure it behaves as expected.
Debugging: It can be used to debug smart contracts by simulating transactions and observing the state changes or return values without affecting the live contract.
Estimating Gas Costs: Although eth_call does not actually send a transaction, it can be used to estimate the gas costs of a transaction by simulating its execution.
