internals notes
- gas is the EVM cost of running the contract (the gas limit)
- if you input a higher number, this is ok, because whatever doesn't get used gest refunded (test this)
- gasPrice is how much I'm willing to pay per gas based on market forces. Mainnet is typically 20 gwei (20000000000 wei)
