- A 3rd-party (central) address set by contract deployer can revert tokens sent to a victim address.
- Salmonela dupe
- Need to add owner address overrides (which bypass the toxic transfer) once bot contracts are deployed*
- Non-toxic baseline
- Pausible ERC20
- *First, enter change token name in deploy.js

MaxFeePerGas = Base fee + maxPriorityFee.
- MaxFeePerGas = absolute max user is willing to pay on gas
- Base fee = algorithmically determined cost per unit of gas based on how full blocks are.
- maxPriorityFee = tip miners. Minimum tip for your tx to be mined = 1 gwei, or .000000001 eth.
- For non-Flashbots miners, MaxPriorityFee is the tip to miners. Standard Ethereum Miners receive (per block): maxFeePerGas - base fee.
- new packages (@ethereumjs/tx and axios) installed - need to
npm i - Calculates gas fees for current block.
- Calculates last 10 blocks baseGasFees, formats to dec, reduces, gets average
- Just how Dan sends these tx's in the video but we can use other methods
