-- [#2074](https://github.com/NibiruChain/nibiru/pull/2074) - fix(evm-keeper): better utilize ERC20 metadata during FunToken creation. The bank metadata for a new FunToken mapping ties a connection between the Bank Coin's `DenomUnit` and the ERC20 contract metadata like the name, decimals, and symbol.  This change brings parity between EVM wallets, such as MetaMask, and Interchain wallets like Keplr and Leap.
