Devcon touches down in Mumbai on 3–6 November 2026, and the calendar attached to this listing has one narrow job: collecting the side events that sprout around Ethereum's flagship gathering — run by the community, and explicit that it is not the Ethereum Foundation.
Mumbai takes its turn in the spotlight
Devcon is the gathering where Ethereum's developers, researchers and enthusiasts share insights and innovations in person — part conference, part family reunion for the protocol's ecosystem. From 3–6 November 2026 it lands in Mumbai, India, a city whose scale, engineering talent and developer energy make it a fitting stage for a community that measures itself in contributors rather than market caps.
Four days is the shape of it. The core programme gives Ethereum's working groups, client teams and researchers a shared room, while the host city supplies the context: India has one of the largest developer populations on earth, and putting the protocol's flagship event in front of that pool is its own statement about where the next generation of builders comes from.
The side-event economy
Around any Devcon, a second conference assembles itself. Community teams book nearby spaces for workshops, deep dives, regional meetups and working sessions that would never fit the main agenda but often deliver more per hour for specialists. This listing exists to gather exactly that layer, covering the 3–6 November window as events accumulate.
The strategy for attendees is to plan both layers at once. Main-stage days give breadth; side events give depth — a client-team breakdown, a standards discussion, a regional community dinner. Following this calendar from now through October means watching the shadow programme take shape in time to build a realistic schedule instead of choosing between three rooms you wanted at midnight.
Note what the calendar is not: a substitute for the main conference. Devcon itself carries the keynotes, the announcements and the weight of Ethereum Foundation coordination; the satellites carry specificity. The pairing works when you respect that division — attend the core days for orientation, then let the side programme take you deep on whatever your work actually touches. Builders hunting collaborators should weight the latter heavily; newcomers to the ecosystem should probably do the opposite.
Clearly labelled community stewardship
One line on the page does important work: this calendar is managed by the community, not the Ethereum Foundation. At the time of writing it is still flagged as launching soon, with a follow button for notifications and a submission path for organisers adding their events. That transparency about provenance is rarer than it should be and worth trusting accordingly.
Practically, it means quality control is distributed. Each listed side event stands on its own host's credibility, so confirm times, venues and access rules with each organiser rather than assuming the calendar polices them. Used that way — as a crowdsourced index, not a guarantee — it is the right tool for the week.
Planning a November week in Mumbai
November sits comfortably after Mumbai's monsoon, with dry, warm days that make multi-venue hopping tolerable even with traffic taken into account. Distances in the city are real, so cluster your side-event picks geographically where possible and budget travel time honestly — the most common Devcon-week mistake everywhere is treating a twenty-minute map estimate as a promise.
Accommodation near whichever neighbourhood concentrates the programming will move early; Devcon weeks reliably inflate demand across entire districts. Track the official Devcon channels for the core conference alongside this community calendar for the satellites, and you will be able to assemble the full week — main stage, side rooms and the informal evenings in between — before flights get expensive.
