Transaction

eth_call

Executes a new message call immediately, without creating a transaction on the block chain. The eth_call method can be used to query internal contract state, to execute validations coded into a contract or even to test what the effect of a transaction would be without running it live.

Parameters

callObject has the following properties:

}

stateOverrideSet has the following properties:

The goal of the state override set is manyfold:

  • It can be used by DApps to reduce the amount of contract code needed to be deployed on chain. Code that simply returns internal state or does pre-defined validations can be kept off chain and fed to the node on-demand.

  • It can be used for smart contract analysis by extending the code deployed on chain with custom methods and invoking them. This avoids having to download and reconstruct the entire state in a sandbox to run custom code against.

  • It can be used to debug smart contracts in an already deployed large suite of contracts by selectively overriding some code or state and seeing how execution changes. Specialized tooling will probably be necessary.

Example - stateOverrideSet

{
  "0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3": {
    "balance": "0xde0b6b3a7640000"
  },
  "0xebe8efa441b9302a0d7eaecc277c09d20d684540": {
    "code": "0x...",
    "state": {
      "0ccfa7da0b3522161999fd723e497b1a3556598653325c2fe7f0b2a98c9d6aae": "c70447ca5ce4344e32ae8234c5e70a446e26b39a5b636b502983ea7a555ab21c"
    }
  }
}

Example

To test call in meaningful way, you need to setup test environment like below.

  • Deploy KIP-7 Contract to test call or you can use it with already deployed one.

    • We will use KIP-7 contract function totalSupply to check whether call is working or not in this example.

    • To call totalSupply you should know about its function signature which is 0x18160ddd.

In this example:

  • The address of KIP-7 contract: 0xbE3892d33620bE5aca8c75D39e7401871194d290 (You should use an existing contract address.)

  • The address of caller: 0xca7a99380131e6c76cfa622396347107aeedca2d

curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method": "eth_call", "params": [{"from": "0xca7a99380131e6c76cfa622396347107aeedca2d", "to": "0xbE3892d33620bE5aca8c75D39e7401871194d290", "input": "0x18160ddd"}, "latest"], "id": 1}' http://localhost:8551

Example - StateOverrides

Following the example above, let's test call using state overrides feature.

  • We will replace the bytecode of 0xbE3892d33620bE5aca8c75D39e7401871194d290 which is the address of KIP-7 contract already deployed above (Check the above example).

  • The bytecode to be replaced is 6080604052600436106049576000357c0100000000000000000000000000000000000000000000000000000000900463ffffffff1680632e64cec114604e5780636057361d146076575b600080fd5b348015605957600080fd5b50606060a0565b6040518082815260200191505060405180910390f35b348015608157600080fd5b50609e6004803603810190808035906020019092919050505060a9565b005b60008054905090565b80600081905550505600a165627a7a723058207783dba41884f73679e167576362b7277f88458815141651f48ca38c25b498f80029 .

    • The original source code of this bytecode is below.

pragma solidity ^0.4.24;

/**
 * @title Storage
 * @dev Store & retrieve value in a variable
 */
contract Storage {

    uint256 number;

    /**
     * @dev Store value in variable
     * @param num value to store
     */
    function store(uint256 num) public {
        number = num;
    }

    /**
     * @dev Return value 
     * @return value of 'number'
     */
    function retrieve() public view returns (uint256){
        return number;
    }
}

Now let's override the state of 0xbE3892d33620bE5aca8c75D39e7401871194d290 (KIP-7 contract) with another contract's byte code (Storage contract) and call retrieve (function signature: 0x2e64cec1) of Storage contract.

eth_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

Parameters

callObject has the following properties:

Fields of transaction can be different based on transaction types. Currently, there are three types of transactions in Ethereum(Legacy, AccessList , DynamicFee).

Object - A transaction object, or null when no transaction was found:

Legacy Transaction
