func NewServer

func NewServer(w *ecs.World, opts ...Option) (Server, error)

NewServer returns a new EVM connection server. This server is responsible for handling requests originating from the EVM. It runs on a default port of 9020, but a custom port can be set using options, or by setting an env variable with key CARDINAL_EVM_PORT.

NewServer will return ErrNoEvmTypes if no transactions OR queries were given with EVM support.
