Key Points
- Program Deployment: Use
add_program()to deploy a program from bytes - include_bytes!: Embeds the compiled program at compile time
- Program ID: Use the keypair from
target/deploy/ - Instructions: Create custom instructions with program ID, accounts, and data
- Log Verification: Check transaction logs to verify program execution
