Title: Specifying a PDA Owned by Different Programs in Anchor

Introduction:

Anchor, a popular decentralized exchange (DEX), allows users to hold and manage multiple assets across different wallets. Specifying a Program Daemon Address (PDA) owned by different programs can be complicated. In this article, we will walk you through the steps required to do this in the Anchor app.

Step 1: Create a PDA Account

To specify a PDA owned by different programs, you must first create a PDA account on Anchor. Here’s how:

• Log in to your Anchor account.

• Click on the “Wallets” tab, then select “Create Wallet.”

• Select “PDA” as the wallet type, then click the “Create” button.

• Fill in the required information, including:

• Account Name

• Program Names (i.e., the names of the programs that own your assets)

• Click the “Create PDA” button to create a new PDA account.

Step 2: Add Programs to Your PDA Account

Once you have created your PDA account, you will need to add the programs that own your assets. Here’s how:

• Log in to your Anchor wallet.

• Select the PDA account you created.

• Click the “Programs” tab, then select “Add Program”.

• Enter the program names for each asset you want to manage (e.g. SOL, SPL).

• Repeat this process for each asset you want to manage.

Step 3: Specify which PDA is owned by which program

Now that you have added programs to your PDA account, you can specify which devices belong to which PDA:

• Log in to your Anchor wallet.

• Select the PDA account you created.

• Click the “Programs” tab, then select “Manage”.

• In the “PDA” section, click “Edit PDA”.

• In the “Device Mapping” field, add each device as a separate entry and specify which program owns it (e.g. SOL: MY_FST_SEED, SPL: MY_SND_SEED).

• Repeat this process for each device you want to manage.

Step 4: Verify PDA Ownership

Finally, verify that your PDA ownership is correct by checking the “PDA” section of each account:

• Log in to your Anchor wallet.

• Select the PDA account you created.

• Click the “Programs” tab, then select “Manage.”

• In the “PDA” section, verify that each device is correctly assigned to the correct program.

Conclusion:

Indicating which PDA is owned by different programs in Anchor may seem complicated, but these steps should get you there. Don’t forget to add programs to your PDA account and specify which PDA has which device for accurate asset management across multiple wallets.
