# Create a Sub-Wallet

This API is used to create a new stablecoin wallet for a specific merchant.\
Once successfully created, the wallet can receive on-chain stablecoin transfers and can be associated with payment links or payment orders.

The platform distinguishes between a **Primary Wallet** and a **Sub Wallet**, which differ in functionality and intended usage.

#### Wallet Types

**Primary Wallet**

* Provides full fund management capabilities, including:
  * Stablecoin on-chain deposits
  * Stablecoin withdrawals
* Typically used for the merchant’s main settlement and fund management purposes

**Sub Wallet**

* Intended for internal accounting and bookkeeping purposes only
* Does not support independent on-chain deposits or withdrawals
* Commonly used for:
  * Business line segregation
  * Financial accounting
  * Payment data tracking and reconciliation

#### Usage Notes

* Each merchant has at least one **Primary Wallet** by default
* Creating sub wallets does not affect the ownership of the merchant’s actual on-chain assets
* Payment links may be associated with sub wallets for accounting categorization purposes, while all on-chain funds are credited to the merchant’s **Primary Wallet**
