+## Understanding eth_call and eth_getBalance
+
+### Exploring eth_call
+
+While exploring contract interactions and blockchain data retrieval, it is important for DApp developers to use the `eth_call` method to simulate and execute message calls directly in the node’s Virtual Machine (VM), without making any modifications and without creating a transaction to the blockchain. This read-only interaction capability is quintessential for querying smart contract functions, such as retrieving ERC-20 token balances with the `balanceOf` function.
+
+Moralis offers a groundbreaking equivalent for `eth_call` with the [getBlock](/web3-data-api/evm/reference/get-block) RPC method, showcasing its innovative approach to data retrieval and blockchain interactions. This endpoint serves as a modern alternative, allowing developers to access extensive information about transactions, contract interactions, and more, all in a user-friendly manner.
+
+### Exploring eth_getBalance
+
+Developers use `eth_getBalance` to get the Ether balance of a given address or in other words to return account's balance of a given address. This method is a fundamental aspect for managing transactions and displaying real-time user balance information.
+
+Moralis presents the [getNativeBalance](/web3-data-api/evm/reference/get-native-balance) RPC method as the nearest equivalent to `eth_getBalance`. You can use it to obtain the native balance of an address which can be an important part in transaction management.

 ## Traditional vs. Modern: A Quick Comparison
 
 Historically, developers have used Ethereum's `eth_call` RPC method to interact with contracts without modifying the blockchain state. Here is an example:

 ## The Gateway to Ethereum Events with eth_getLogs
 
+The `eth_getLogs` is a JSON-RPC method in Ethereum that returns event data as an array of all logs matching a specified filter object. It is a fundamental method for querying and retrieving event logs from the Ethereum blockchain.
+
 The utilization of `eth_getLogs` plays a vital role in the blockchain industry as it empowers developers with a valuable tool to monitor and analyze events occurring on the Ethereum blockchain. Throughout this guide, we will delve into the functions and benefits of this tool and look at the advantages of using Moralis instead.
 
 Also, transaction receipts serve as repositories for Ethereum event logs, capturing details such as gas consumption, transaction status, and more. Understanding storage dynamics allows us to efficiently retrieve this information using methods like `eth_getLogs` along with other alternatives.
