I WANT:

I simply want to send hundreds of tx to my local node.

I DO:

  1. install this extension
  2. write my script
  3. execute test
  4. get a error 😢

MY MACHINE:

  • MacBook Air M2: 8gb

STEPS

install this extension

>>> docker run --rm -e GOOS=darwin -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" \
  grafana/xk6 build \
  --with github.com/distribworks/xk6-ethereum
