Question

I'm trying to have a simple program written in Solana that, on user approval, runs and transfers a given amount of SOL into the program's owner account.

        ...
        const secretKeyString = await fs.readFile(filePath, {encoding: 'utf8'});
        const secretKey = Uint8Array.from(JSON.parse(secretKeyString))
        const keypair = Keypair.fromSecretKey(secretKey)

        const instruction = new TransactionInstruction({
            keys: [
              {pubkey: publicKey, isSigner: false, isWritable: true}, // from wallet
              {pubkey: keypair.publicKey, isSigner: false, isWritable: true} // from json file, program owner
            ],
            programId,
            data: Buffer.alloc(0)
          });

        const transaction = new Transaction().add(instruction);
        signature = await sendTransaction(transaction, connection);
        //toast('Transaction Sent');

The system level SOL transfer<\/code> has a constraint that the from<\/code> PublicKey must be a system owned account<\/strong><\/em> . This means accounts owned by programs or PDA will fail as they are owned by your program.https:\/\/solanacookbook.com\/references\/accounts.html#transfer<\/a>
