The `AccountRoot` object type describes a single _account_ object. Example `AccountRoot` object:

```json
{
    "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
    "AccountTxnID": "0D5FB50FA65C9FE1538FD7E398FFFE9D1908DFA4576D8D7A020040686F93C77D",
    "Balance": "148446663",
    "Domain": "6D64756F31332E636F6D",
    "EmailHash": "98B4375E1D753E5B91627516F6D70977",
    "Flags": 8388608,
    "LedgerEntryType": "AccountRoot",
    "MessageKey": "0000000000000000000000070000000300",
    "OwnerCount": 3,
    "PreviousTxnID": "0D5FB50FA65C9FE1538FD7E398FFFE9D1908DFA4576D8D7A020040686F93C77D",

}
```

The `AccountRoot` object has the following fields:

| Field                         | JSON Type | [Internal Type][] | Description  |
|:------------------------------|:----------|:------------------|:-------------|
| `LedgerEntryType`             | String    | UInt16            | The value `0x0061`, mapped to the string `AccountRoot`, indicates that this is an AccountRoot object. |

| `Sequence`                    | Number    | UInt32            | The sequence number of the next valid transaction for this account. (Each account starts with Sequence = 1 and increases each time a transaction is made.) |
| `AccountTxnID`                | String    | Hash256           | _(Optional)_ The identifying hash of the transaction most recently submitted by this account. |

### AccountRoot Flags

There are several options which can be either enabled or disabled for an account. These options can be changed with an [AccountSet transaction][]. In the ledger, flags are represented as binary values that can be combined with bitwise-or operations. The bit values for the flags in the ledger are different than the values used to enable or disable those flags in a transaction. Ledger flags have names that begin with _lsf_.

AccountRoot objects can have the following flag values:

| Flag Name | Hex Value | Decimal Value | Description | Corresponding [AccountSet Flag](reference-transaction-format.html#accountset-flags) |
|-----------|-----------|---------------|-------------|-------------------------------|
| lsfPasswordSpent | 0x00010000 | 65536 | Indicates that the account has used its free SetRegularKey transaction. | (None) |
| lsfRequireDestTag | 0x00020000 | 131072 | Requires incoming payments to specify a Destination Tag. | asfRequireDest |
| lsfRequireAuth | 0x00040000 | 262144 | This account must individually approve other users for those users to hold this account's issuances. | asfRequireAuth |
| lsfDisallowXRP | 0x00080000 | 524288 | Client applications should not send XRP to this account. Not enforced by `rippled`. | asfDisallowXRP |
| lsfDisableMaster | 0x00100000 | 1048576 | Disallows use of the master key to sign transactions for this account. | asfDisableMaster |
| lsfNoFreeze | 0x00200000 | 2097152 | This address cannot freeze trust lines connected to it. Once enabled, cannot be disabled. | asfNoFreeze |
| lsfGlobalFreeze | 0x00400000 | 4194304 |　All assets issued by this address are frozen. | asfGlobalFreeze |
| lsfDefaultRipple | 0x00800000 | 8388608 | Enable [rippling](concept-noripple.html) on this addresses's trust lines by default. Required for issuing addresses; discouraged for others. | asfDefaultRipple |

### AccountRoot ID Format

The ID of an AccountRoot object is the [SHA-512Half](#sha512half) of the following values, concatenated in order:

* The Account space key (`0x0061`)
* The AccountID of the account
