Hola @carovidela Estas usando el chainId 1337, asegure que ese id corresponda a tu instancia de ganache, si estas desplegando esto en un live network tienes que user el código correcto para esa blockchain.

Hola Gracias por responder si asi es

Ok, el error the cytools es bastante común, hay varias formas arreglar estoÑ

  1. usar WSL y manejar tu entorno de desarrollo en Linux desde Windows.
  2. Instalar Visual Studio Community para windows y sus herramientas de desarrollo para python.

Bueno pude solucionar esto Instale WSL y esta manejando en el entorno de win con linux

carovidela commented 1 year ago

Queria contarles que pude solucionar los errores de conexion de WSL2 y ganache.

Si probaba la aplicacion con los datos proporcionados con la ejecucion de ganache-cli en ubuntu, compilaba correctamente. Sin embargo al usar la gui de ganache para win no lograba conectarse a la RPC informada.

Lo solucion permitiendo el acceso de ganache en el firewall de win en todos sus puertos y conexiones. Espero sea util para alguien mas.

Saldos
