The Single Asset Vault uses [Multi-Purpose-Token](https://github.com/XRPLF/XRPL-Standards/tree/master/XLS-0033-multi-purpose-tokens) to represent ownership shares of the Vault. The Vault serves diverse purposes, such as lending markets, aggregators, yield-bearing tokens, asset management, etc. The Single Asset Vault decouples the liquidity provision functionality from the specific protocol logic.

Vault Owners set the currency code of the share and whether the token is transferable during the vault's creation. These two values are immutable. The share is represented by a [Multi-Purpose Token](https://github.com/XRPLF/XRPL-Standards/tree/master/XLS-0033-multi-purpose-tokens). The MPT is issued by the vault's pseudo-account. -##### 2.1.6.1 `Scale` +#### 2.6.1 `Scale` The **`Scale`** field enables the vault to accurately represent fractional asset values using integer-only MPT shares, which prevents the loss of value from decimal truncation. It defines a scaling factor, calculated as $10^{\text{Scale}}$, that converts a decimal asset amount into a corresponding whole number of shares. For example, with a `Scale` of `6`, a deposit of **20.3** assets is multiplied by $10^6$ and credited as **20,300,000** shares. As a general rule, all calculations involving MPTs are executed with a precision of a single MPT, treating them as indivisible units. If a calculation results in a fractional amount, it will be rounded up, down or to the nearest whole number depending on the context. Crucially, the rounding direction is determined by the protocol and is not controlled by the transaction submitter, which may lead to unexpected results. -##### 2.1.6.1.1 `IOU` +##### 2.6.1.1 `IOU` When a vault holds an **`IOU`**, the `Scale` is configurable by the Vault Owner at the time of the vault's creation. The value can range from **0** to a maximum of **18**, with a default of **6**. This flexibility allows issuers to set a level of precision appropriate for their specific token. -##### 2.1.6.1.2 `XRP` +##### 2.6.1.2 `XRP` When a vault holds **`XRP`**, the `Scale` is fixed at **0**. This aligns with XRP's native structure, where one share represents one drop (the smallest unit of XRP), and one XRP equals 1,000,000 drops. Therefore, a deposit of 10 XRP to an empty Vault will result in the issuance of 10,000,000 shares ($10 \times 10^6$). -##### 2.1.6.1.3 `MPT` +##### 2.6.1.3 `MPT` When a vault holds `MPT`, its `Scale` is fixed at **0**. This creates a 1-to-1 relationship between deposited MPT units and the shares issued (for example, depositing 10 MPTs to an empty Vault issues 10 shares). The value of a single MPT is determined at the issuer's discretion. If an MPT is set to represent a large value, the vault owner and the depositor must be cautious. Since only whole MPT units are used in calculations, any value that is not a multiple of a single MPT's value may be lost due to rounding during a transaction. -##### 2.1.6.2 `MPTokenIssuance` +#### 2.6.2 `MPTokenIssuance` The `MPTokenIssuance` object represents the share on the ledger.
