crazed-nft-fans

A new NFT has dropped, but its location is a secret! Fans have become crazed, and are sending funds to random wallets and calling gas guzzling contracts as fast as they can to hopefully snag it.

Using the fans on a simulated network (like geth in dev mode) can help you emulate network congestion events.

If using a simulated geth instance, you might find it helpful to turn on metrics.

Configure

Environment variables are used to configure everything about the crazed fans.

HTTP_URL="http://localhost:8545" # HTTP URL of the chain to run on
WS_URL="ws://localhost:8546" # WS URL of the chain to run on
CHAIN_ID="1337" # ID of the chain to run on
FUNDING_KEY="ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80" # Private key of the funding address
CRAZED_LEVEL="0" # See below

Crazed Levels

You can set how intensely the fans will interact with the chain using the CRAZED_LEVEL env var. This controls how high fans will set their gas tips, and how often they decide to replace transactions with higher gas tips.

var CrazedLevelMappings = map[int]string{
  0: "Mixed", // Randomly assigns each fan one of the below statuses
  1: "Indifferent",
  2: "Curious",
  3: "Interested",
  4: "Obsessed",
  5: "Manic",
}

Test

make test

to run basic tests in standard go format, or

make test_fancy

to run basic tests with a prettier output, or

make test_integration

to launch a simulated geth node to run all possible tests.

Can I use this to cause chaos on ethereum mainnet or testnets?

Maybe? But I wouldn't recommend it, unless you are looking for a way to become very poor, very fast. There's far more fun ways to do that anyway.
