## Properties

### Account

Account: string

The unique address of the transaction sender.

Inherited from BaseTransaction.Account

- Defined in packages/xrpl/src/models/transactions/common.ts:225

### `Optional` AccountTxnID

AccountTxnID?: string

Hash value identifying another transaction. If provided, this transaction is only valid if the sending account's previously-sent transaction matches the provided hash.

Inherited from BaseTransaction.AccountTxnID

- Defined in packages/xrpl/src/models/transactions/common.ts:249

### `Optional` Fee

Fee?: string

Integer amount of XRP, in drops, to be destroyed as a cost for distributing this transaction to the network. Some transaction types have different minimum requirements.

Inherited from BaseTransaction.Fee

- Defined in packages/xrpl/src/models/transactions/common.ts:236

### `Optional` Flags

Flags?: number | GlobalFlags

Set of bit-flags for this transaction.

Inherited from BaseTransaction.Flags

- Defined in packages/xrpl/src/models/transactions/common.ts:251

### `Optional` LastLedgerSequence

LastLedgerSequence?: number

Highest ledger index this transaction can appear in. Specifying this field places a strict upper limit on how long the transaction can wait to be validated or rejected.

Inherited from BaseTransaction.LastLedgerSequence

- Defined in packages/xrpl/src/models/transactions/common.ts:257

### LedgerSequence

LedgerSequence: number

The ledger index where this pseudo-transaction appears. This distinguishes the pseudo-transaction from other occurrences of the same change.

- Defined in packages/xrpl/src/models/transactions/UNLModify.ts:14

### `Optional` Memos

Memos?: Memo []

Additional arbitrary information used to identify this transaction.

Inherited from BaseTransaction.Memos

- Defined in packages/xrpl/src/models/transactions/common.ts:261

### `Optional` NetworkID

NetworkID?: number

The network id of the transaction.

Inherited from BaseTransaction.NetworkID

- Defined in packages/xrpl/src/models/transactions/common.ts:293

### `Optional` Sequence

Sequence?: number

The sequence number of the account sending the transaction. A transaction is only valid if the Sequence number is exactly 1 greater than the previous transaction from the same account. The special case 0 means the transaction is using a Ticket instead.

Inherited from BaseTransaction.Sequence

- Defined in packages/xrpl/src/models/transactions/common.ts:243

### `Optional` Signers

Signers?: Signer []

Array of objects that represent a multi-signature which authorizes this transaction.

Inherited from BaseTransaction.Signers

- Defined in packages/xrpl/src/models/transactions/common.ts:266

### `Optional` SigningPubKey

SigningPubKey?: string

Hex representation of the public key that corresponds to the private key used to sign this transaction. If an empty string, indicates a multi-signature is present in the Signers field instead.

Inherited from BaseTransaction.SigningPubKey

- Defined in packages/xrpl/src/models/transactions/common.ts:279

### `Optional` SourceTag

SourceTag?: number

Arbitrary integer used to identify the reason for this payment, or a sender on whose behalf this transaction is made. Conventionally, a refund should specify the initial payment's SourceTag as the refund payment's DestinationTag.

Inherited from BaseTransaction.SourceTag

- Defined in packages/xrpl/src/models/transactions/common.ts:273

### `Optional` TicketSequence

TicketSequence?: number

The sequence number of the ticket to use in place of a Sequence number. If this is provided, Sequence must be 0. Cannot be used with AccountTxnID.

Inherited from BaseTransaction.TicketSequence

- Defined in packages/xrpl/src/models/transactions/common.ts:284

### TransactionType

TransactionType: "UNLModify"

The type of transaction. Valid types include: `Payment`, `OfferCreate`, `TrustSet`, and many others.

Inherited from BaseTransaction.TxnSignature

- Defined in packages/xrpl/src/models/transactions/common.ts:289

### UNLModifyDisabling

UNLModifyDisabling: 0 | 1

If 0, this change represents removing a validator from the Negative UNL. If 1, this change represents adding a validator to the Negative UNL.

- Defined in packages/xrpl/src/models/transactions/UNLModify.ts:19

### UNLModifyValidator

UNLModifyValidator: string

The validator to add or remove, as identified by its master public key.

- Defined in packages/xrpl/src/models/transactions/UNLModify.ts:21
