 - [#2088](https://github.com/NibiruChain/nibiru/pull/2088) - refactor(evm): remove outdated comment and improper error message text
 - [#2089](https://github.com/NibiruChain/nibiru/pull/2089) - better handling of gas consumption within erc20 contract execution
 - [#2091](https://github.com/NibiruChain/nibiru/pull/2091) - feat(evm): add fun token creation fee validation
+- [#2xxx](https://github.com/NibiruChain/nibiru/pull/2xxx) - fix(evm): Following
+from the changs in #2086, this pull request implements two critical security
+fixes. 
+   1. First, we add new `JournalChange` struct that saves a deep copy of the
+      state multi store before each state-modifying, Nibiru-specific precompiled
+   contract is called (`OnRunStart`). Additionally, we commit the `StateDB` there
+   as well. This guarantees that the non-EVM and EVM state will be in sync even
+   if there are complex, multi-step Ethereum transactions, such as in the case of
+   an EthereumTx that influences the `StateDB`, then calls a precompile that also
+   changes non-EVM state, and then EVM reverts inside of a try-catch.
+   2. Second, the solution from #2086 that records NIBI (ether) transfers on the
+      `StateDB` during precompiled contract calls is generalized as
+   `NibiruBankKeeper`, which is struct extension of the `bankkeeper.BaseKeeper`
+   that is used throughout the Nibiru base application. The `NibiruBankKeeper`
+   holds a reference to the current EVM `StateDB` if there is one and records
+   balance changes in wei as journal changes automatically.
