Mythril builds its own contract database to enable fast search operations. Unfortunately, this process is slow. You don't need to sync the whole blockchain right away though: If you abort the syncing process with `ctrl+c`, it will be auto-resumed the next time you run the `--init-db` command.

Unfortunately, the initial sync process is slow. You don't need to sync the whole blockchain right away though: If you abort the syncing process with `ctrl+c`, it will be auto-resumed the next time you run the `--init-db` command.
