What format should my private key be in?
The private key should be in the base58 string format, not bytes.
Why are my transactions being dropped?
You get what you pay for. Don't use the main-net RPC, just spend the money for Helius or Quick Node.
How do I change the fee?
Modify the unit_budget and unit_price values.
Does this code work on devnet?
No.
