Functions

func AddressFromBalancesStore

func AddressFromBalancesStore(key []byte) (sdk.AccAddress, error)

func CreateAccountBalancesPrefix

func CreateAccountBalancesPrefix(addr []byte) []byte

func DenomMetadataKey

func DenomMetadataKey(denom string) []byte

DenomMetadataKey returns the denomination metadata key.

func MigrateJSON

func MigrateJSON(oldState *types.GenesisState) *types.GenesisState

MigrateJSON accepts exported v0.40 x/bank genesis state and migrates it to v0.43 x/bank genesis state. The migration includes: - Prune balances & supply with zero coins (ref: https://github.com/cosmos/cosmos-sdk/pull/9229)

func MigrateStore

func MigrateStore(ctx sdk.Context, storeKey storetypes.StoreKey, cdc codec.BinaryCodec) error

MigrateStore performs in-place store migrations from v0.40 to v0.43. The migration includes:

- Change addresses to be length-prefixed. - Change balances prefix to 1 byte - Change supply to be indexed by denom - Prune balances & supply with zero coins (ref: https://github.com/cosmos/cosmos-sdk/pull/9229)
