Where and when is it held?

Open Protocol takes place on Wednesday 29th and Thursday 30th November in Helsinki, Finland. It’s hosted at an incredible, state-of-the-art venue in the city.


You can join Open Protocol as an attendee, speaker, sponsor or media representative. Please note, to ensure the highest quality event possible, all participation is by application-only. All spots are limited and in high demand.

You can submit your speaker papers here.

Open Protocol was spun out of the Slush technology conference in Helsinki as a standalone event. Last year it was the largest Web3 event in the Nordics to date with over 15% of the entire Slush population applying (1800 applicants) to attend. So we recommend applying early.

Yes. If you are actively involved in a relevant media publication you can join Open Protocol for free with a Media Pass.

Please apply for your Media Pass here.

Open Protocol is a Web3-only conference on 29th and 30th November 2023 and Slush is a general technology entrepreneurship conference on 30th and 31st November 2023.

A ticket for Slush does not given you access to Open Protocol and vice versa.

But both events are in Helsinki during overlapping dates, so you can enjoy both simultaneously as many attendees do.

Sadly we can’t help with visa invitation letters unless you are an Open Protocol speaker.
