Web3 Events Calendar 2026

Priority targets for the Ecosystem track — hackathons, conferences, and platforms

// last updated: May 2026 · Track 02 — Ecosystem

How to read this

Sponsoring vs. Attending

For hackathons, the goal is an infrastructure sponsor slot (devs get Chainstack credits by default). For conferences, the goal is a speaking slot or side event — not a booth.

Tier 1 — must be there (either as sponsor or speaker). Tier 2 — evaluate ROI closer to the date. Tier 3 — monitor, participate remotely or via content.

Chainstack already won prizes at ETHGlobal Istanbul — there's an existing relationship to build on. The goal is to convert that into a recurring annual partnership.

Hackathon Series

ETHGlobal 2026

Most relevant for developer ecosystem. 800+ developers per event. Infra sponsor = Chainstack becomes the default RPC for every project.

Event	Dates	Location	Status	Notes
ETHGlobal Cannes	Apr 3–5, 2026	Cannes, France	✅ Past	—
ETHGlobal New York	Jun 12–14, 2026	New York, USA	🔜 Soon	Google Cloud already in as sponsor — confirm if infra slot is exclusive
ETHGlobal Lisbon	Jul 24–26, 2026	Lisbon, Portugal	🟡 Target	Good timing to be on board by then
ETHGlobal Tokyo	Sep 25–27, 2026	Tokyo, Japan	🟡 Target	Asia market, relevant for Chainstack's Singapore base
ETHGlobal Mumbai	Q4 2026	Mumbai, India	🟡 Target	Coincides with Devcon 8 window — high-density week

Action: Contact ETHGlobal partnerships team. Ask about sponsor tiers, exclusivity on infra category, and what a recurring annual partnership looks like.

Major Conferences

2026 Conference Calendar

Format goal is always speaking slot or side event — booths don't work for developer audiences.

Event	Dates	Location	Tier	Format Goal
ETHDenver	Feb 17+	Denver, USA	Tier 1	Speaking slot / side event
Paris Blockchain Week	Apr 15–16	Paris, France	Tier 2	Speaking slot
TOKEN2049 Dubai	~Apr	Dubai, UAE	Tier 1	Side event / networking
EthCC	~Jul	Brussels area	Tier 1	Speaking slot — builder audience
TOKEN2049 Singapore	~Sep	Singapore	Tier 1	Side event — home turf, 25K+ attendees
Consensus Miami	2026	Miami, USA	Tier 2	Panel or side event
Devcon 8	Late Q4	Mumbai, India	Tier 1	Ethereum core community
Korea Blockchain Week	~Sep	Seoul, Korea	Tier 2	Asia expansion

TOKEN2049 Singapore: World's largest crypto event by attendance (25K+, 7K+ companies). Chainstack is Singapore-based — owning this event with a side event or workshop is a high-leverage move.
