Instruction 0: Instruction Expected An Executable Account
Introduction
When working with the Solend protocol and Anchor, it's not uncommon to encounter errors related to executable accounts. In this article, we'll delve into the issue of "instruction expected an executable account" and provide a step-by-step guide on how to resolve it.
Understanding Executable Accounts
Before we dive into the solution, it's essential to understand what executable accounts are. In the context of Solend and Anchor, an executable account is an account that has been initialized with a program ID, which allows it to execute instructions. This is a crucial concept, as it enables accounts to interact with each other and the Solend protocol.
The Error: Instruction Expected an Executable Account
When you encounter the error "instruction expected an executable account," it means that the account you're trying to interact with does not have a program ID associated with it. This can happen for several reasons, including:
- The account has not been initialized with a program ID.
- The program ID associated with the account is incorrect.
- The account is not properly configured in the Anchor.toml file.
Resolving the Error: A Step-by-Step Guide
To resolve the error "instruction expected an executable account," follow these steps:
Step 1: Verify the Account Configuration
First, verify that the account you're trying to interact with is properly configured in the Anchor.toml file. Check the [[test.genesis]] section to ensure that the address and program fields are correct.
[[test.genesis]]
address = "So1endDq2YkqhipRh3WViPa8hdiSpxWy6z3Z6tMCpAo"
program = "your_program_id"
Step 2: Initialize the Account with a Program ID
If the account is not initialized with a program ID, you'll need to create a new program ID and associate it with the account. You can do this using the Anchor CLI tool.
anchor init --program-id your_program_id
Step 3: Update the Anchor.toml File
Once you've created a new program ID, update the [[test.genesis]] section in the Anchor.toml file to reflect the new program ID.
[[test.genesis]]
address = "So1endDq2YkqhipRh3WViPa8hdiSpxWy6z3Z6tMCpAo"
program = "your_new_program_id"
Step 4: Rebuild and Re-deploy the Program
After updating the Anchor.toml file, rebuild and re-deploy the program to ensure that the changes take effect.
anchor build
anchor deploy

Introduction
In our previous article, we explored the issue of "instruction expected an executable account" and provided a step-by-step guide on how to resolve it. However, we understand that sometimes, additional clarification is needed to fully grasp the concept. In this Q&A article, we'll address some of the most frequently asked questions related to executable accounts and Anchor.
Q: What is an executable account?
A: An executable account is an account that has been initialized with a program ID, which allows it to execute instructions. This is a crucial concept, as it enables accounts to interact with each other and the Solend protocol.
Q: Why do I need an executable account?
A: You need an executable account to interact with the Solend protocol and other accounts. Without an executable account, you won't be able to execute instructions and perform actions on the Solend protocol.
Q: How do I create an executable account?
A: To create an executable account, you'll need to initialize the account with a program ID using the Anchor CLI tool. You can do this by running the following command:
anchor init --program-id your_program_id
Q: What if I'm using a pre-existing account?
A: If you're using a pre-existing account, you'll need to update the account configuration in the Anchor.toml file to include the program ID. You can do this by adding the following lines to the [[test.genesis]] section:
[[test.genesis]]
address = "So1endDq2YkqhipRh3WViPa8hdiSpxWy6z3Z6tMCpAo"
program = "your_program_id"
Q: What if I'm still encountering issues?
A: If you're still encountering issues after following the steps outlined above, try the following troubleshooting tips:
- Verify that the account is properly configured in the Anchor.toml file.
- Check that the program ID associated with the account is correct.
- Ensure that the account is initialized with a program ID.
- Rebuild and re-deploy the program to ensure that the changes take effect.
Q: What are some common mistakes to avoid?
A: Some common mistakes to avoid when working with executable accounts include:
- Failing to initialize the account with a program ID.
- Using an incorrect program ID.
- Not updating the account configuration in the Anchor.toml file.
- Not rebuilding and re-deploying the program after making changes.
Q: Where can I find more information?
A: For more information on executable accounts and Anchor, refer to the following resources:
