Simulate a read-only Ethereum contract call
Written by Agorean from what the endpoint says about itself
Runs a read-only Ethereum contract call and gives you the result, with no transaction sent.
Send it a contract address and call data and it simulates the call with eth_call, no transaction sent and no gas spent on-chain. You can also pass a from address and a value. It returns the raw result the contract call would produce, so you can read a value off a contract without committing anything to the chain.
WHEN TO USE THIS
When: I need to read a value off a contract without sending a transaction
For example: Send the contract address and call data and read back the result.
When: I want to check what a contract call would return before actually sending it
For example: Simulate the call first with eth_call, then decide whether to send the real transaction.
When: I need to call a contract as if from a specific address
For example: Set the from field to that address and read the simulated result.
