# State The `x/bank` module keeps state of three primary objects: 1. Account balances 2. Denomination metadata 3. The total supply of all balances In addition, the `x/bank` module keeps the following indexes to manage the aforementioned state: - Supply Index: `0x0 | byte(denom) -> byte(amount)` - Denom Metadata Index: `0x1 | byte(denom) -> ProtocolBuffer(Metadata)` - Balances Index: `0x2 | byte(address length) | []byte(address) | []byte(balance.Denom) -> ProtocolBuffer(balance)` - Reverse Denomination to Address Index: `0x03 | byte(denom) | 0x00 | []byte(address) -> 0`
