+A Conflux account state includes four parts:
 
 - ```Basic state``` is the basic state of the account.
 - ```Storage state``` is a key/value database or storage space that can be used to store custom states or data of smart contracts.
 - ```Code information``` is the code information of the smart contract account. It includes the contract codes and the ```address``` of the account that paid the fee for the storage space occupied by the codes.
-- ```Staking deposit list``` is the list of Staking operations of the accounts (it will be removed in the next Hardfork).
 - ```Staking vote lock list``` is the list of lock operations performed by the account to participate in DAO voting.
 
+> ```Staking deposit list``` is already **removed** in the v2.4.0 Hardfork, which is the list of Staking operations of the account.

 The basic status of the account consists of eight fields as follows:
 
 - ```Nonce``` is a counter to keep track of the number of transactions sent by an account. It is also used to ensure that each transaction can only be executed once. For contract accounts, this value indicates the number of ```contracts created by this contract```.

 ## Gas
 
 1. Gas used and refund: Conflux requires less gas in `SSTORE` operation but no longer refunds resetting storage and contract destruction.
-2. Gas Fee Refund: In Ethereum, if a transaction's gas limit exceeds the actual gas cost, the remaining gas is fully refunded. In contrast, Conflux refunds a maximum of 1/4 of the **gas limit**. Setting an excessively high gas limit in Conflux can lead to additional transaction fee costs. However, no extra fees are incurred if the gas limit is set to less than 4/3 of the actual cost. Therefore, providing an accurate gas estimate for a transaction is crucial for optimizing transaction fees.
