Main prop: sub0 - BA 25 Flagship Conference
Polkadot is stepping into a new era.
That’s why we’re proposing a new flagship Polkadot conference in Buenos Aires this November: a 3-day, deeply immersive edition of sub0 that includes a main product stage and grows into a annual global flagship conference for the ecosystem.
Set against the backdrop of Devconnect, in one of the most vibrant Web3 regions in the world, this is Polkadot’s chance to open its doors to the global ecosystem and show what we’re really made of.
This proposal falls outside the scope of ecosystem bounties because of scale. We are happy to bring Polkadot's flagship event to OpenGov!
Check out the full 35-page proposal here.
Review the detailed budget here.
The plan:
- 3,000 attendees over 3 days
- 2 main stages (Product + Development), plus 18 immersive rooms
- 24/7 hackerspace, 2 hackathons with min. $15K in Polkadot bounties (plus sponsor bounties)
- Major activations across gaming, governance, identity and art
- 70% of attendees expected from outside the Polkadot ecosystem
We’re ready for it.
This conference will bring the whole ecosystem together to build, collaborate and move the Polkadot mission forward. All of it free to attend, fully catered, and designed for maximum real-world impact.
We’re inviting the community to help shape this event from the ground up. The proposal is now live.

FAQS
Why not go to the Events Bounty?
Flagships have been historically community-driven initiatives, and a proposal of this size should be as transparent as possible.
Why do you have a success fee?
The budget accounts for 19.5% for WebZero agency fee & salaries, including the success fee if targets above 60% are met. It’s important to add that WebZero salaries are also key functions that save us from outsourcing: social media & content manager, DevRel and hackathon coordination, logistics, set design, creatives & agenda management.
Why Devconnect?
Devconnect is set to be the most significant Web3 conference of the year with 25,000 visitors descending upon Buenos Aires from Nov 10. Timing sub0 during Devconnect captures an already-assembled, highly technical audience, multiplies media reach, and makes travel logistics easier for speakers and sponsors who plan to attend both weeks. This offsets speaker costs to zero, as many high-level figures will be in town.
By running concurrently with Devconnect, we gain significant leverage. This approach amplifies our attendance and allows us to focus our budget on enhancing the event experience, rather than on extensive marketing. Crucially, we still deliver a powerful, uniquely Polkadot-branded presence.
For Polkadot's senior leadership, attending Devconnect is essential, even with many of our representatives based in Europe. Devconnect stands as the world's largest developer conference in web3 and attracts thousands of teams. Therefore, it's strategically vital for our key players to converge during the initial three days to solidify connections, then fan out to capitalise on those relationships within the broader ecosystem.
sub0 Bangkok cost less than 500k, why the price increase?
We're upgrading the experience to include concert-grade immersions, professional-grade livestreaming that will reach thousands globally, new scholarship initiatives, and a refined focus on one of the biggest hackathons on Polkadot. This will be extraordinary and unprecedented.
sub0 Bangkok was our first time organizing a major conference, which severely impacted team health due to a lack of staff and resources. Done in just eight weeks end-to-end, several corners were cut to make the event a success. Agency fees were not included. The venue was an abandoned warehouse without toilets or electricity. Police were called multiple times.
It’s important to add that Argentina is significantly more expensive than Bangkok due to inflation dramatically impacting the country; therefore, costs are much higher.
All quotations have been heavily negotiated, with multiple quotes requested from different vendors per budget item for a full assessment.
Please note that we are aiming to send 10% or more back to the treasury via sponsorship revenue and aim to be well under budget.
