# Keepers

The auth module only exposes one keeper, the account keeper, which can be used to read and write accounts.

# Account Keeper

Presently only one fully-permissioned account keeper is exposed, which has the ability to both read and write all fields of all accounts, and to iterate over all stored accounts.

Copy // AccountKeeperI is the interface contract that x/auth's keeper implements. type AccountKeeperI interface { // Return a new account with the next account number and the specified address. Does not save the new account to the store. NewAccountWithAddress(sdk.Context, sdk.AccAddress) types.AccountI // Return a new account with the next account number. Does not save the new account to the store. NewAccount(sdk.Context, types.AccountI) types.AccountI // Retrieve an account from the store. GetAccount(sdk.Context, sdk.AccAddress) types.AccountI // Set an account in the store. SetAccount(sdk.Context, types.AccountI) // Remove an account from the store. RemoveAccount(sdk.Context, types.AccountI) // Iterate over all accounts, calling the provided function. Stop iteraiton when it returns false. IterateAccounts(sdk.Context, func(types.AccountI) bool) // Fetch the public key of an account at a specified address GetPubKey(sdk.Context, sdk.AccAddress) (crypto.PubKey, error) // Fetch the sequence of an account at a specified address. GetSequence(sdk.Context, sdk.AccAddress) (uint64, error) // Fetch the next account number, and increment the internal counter. GetNextAccountNumber(sdk.Context) uint64 }
