The submitted changes introduce a new feature to the NibiruChain/nibiru project: the ability to register an existing Cosmos coin as an EVM ERC-20 fungible token, known as a "fun token." This feature includes modifications to .proto files, new methods in the Keeper struct, and associated test cases to ensure functionality and robustness.

Poem
Amidst the chains that intertwine,
A coin transforms by design.
With magic code and tokens spun,
Cosmos meets EVM, the fun's begun.
In bytes and blocks, they come alive,
A rabbit's joy, the chains now thrive.
