Day 2 of ETHDenver 2026 just wrapped, and if Day 1 set the tone, Day 2 cranked up the intensity. The National Western Center in Denver is buzzing with the kind of energy that only happens when you put thousands of builders in a room during a bear market — no tourists, no hype merchants, just people who actually give a damn about the future of Ethereum.
The theme? Ethereum Foundation Day. The vibe? Laptops out, heads down, vibes immaculate.
Let's start with the elephant in the room — or rather, the regulators in the room.
SEC Chair Paul Atkins and Commissioner Hester Peirce (aka "Crypto Mom") showed up on Day 1 and delivered a talk titled "Number Go Down and Other Schadenfreude" — yes, that's an actual SEC speech title in 2026. You can't make this up.
The big reveal: an "innovation exemption" for tokenized securities trading on public, permissionless blockchains. The TL;DR:
Issuers can tokenize securities and trade them onchain via AMMs and DeFi mechanisms
Buyers/sellers undergo whitelisting with volume caps
It's a temporary sandbox — a bridge between TradFi and crypto-native platforms
Smart contracts can embed compliance (lockups, KYC, proxy voting)
ZK-proofs can handle privacy and BSA compliance
Peirce's analogy: it's like buying an abandoned storage unit — you won't find gold bars or a monster, but it's a real step forward. After years of "regulation by enforcement," the SEC is finally saying "come in and talk to us." The full speech is on SEC.gov and it's genuinely worth reading.
The EF dropped its 2026 Protocol Priorities Update, outlining two core tracks:
Scale: Consensus, execution, and blob scaling
Improve UX: Seamless, secure interactions for users and developers
This isn't a roadmap — it's a declaration of intent. Ethereum is going all-in on making itself usable, fast, and cheap enough that the "just use Solana" argument loses its teeth.
Brian Armstrong popped up to address the quantum computing threat, calling it a "solvable issue" for crypto. Coinbase has formed a quantum advisory council and is engaging blockchains on post-quantum upgrades. Not panic, just preparation — which is refreshingly adult for this industry.
Day 2's main stage was dedicated to EF talks, and they were dense. No marketing fluff — just protocol engineers and researchers getting into the weeds.
Vitalik opened the week with a main stage presentation that set the philosophical frame for everything that followed. His thesis: the idealistic tech visions from 20 years ago — perfect markets, direct democracy, trust minimization — all failed because of the limits of human attention. AI might finally solve that.
But Vitalik being Vitalik, he followed up with a warning: "It's very irresponsible to treat AI as inscrutable magic." Even local LLMs aren't trustless. Proofs and verifiability still matter. His call to the builder community: think about why Ethereum was created, and ask yourself — "What would you do?"
The Geth core developer outlined a vision for "Less State, More Logs" — a proposal to reduce Ethereum's state bloat using ZK-proofs and trustless log indexing. The idea: enable stateless parallel execution that scales without sacrificing decentralization. It's the kind of talk that makes your brain hurt in the best way.
The EF's AI Lead explored how Ethereum's verifiable, decentralized architecture makes it the ideal base layer for an "agentic economy" — where AI agents can coordinate, transact, and prove their outputs cryptographically without centralized intermediaries. If "agentic finance" was the buzzword of ETHDenver, Crapis provided the intellectual backbone.
The buidlguidl legend showed off tools that let developers deploy full onchain applications in a single transaction — "one-shotting" as he calls it. The goal: lower barriers so dramatically that AI-native projects can iterate at machine speed. Less setup, more shipping.
The EF Co-Executive Director painted a vision of Ethereum as the coordination layer for an AI-driven future: "well-tested systems that never break" delivering credible neutrality and real value for agentic commerce. Security and safety first, always.
The hackathon is deep in building mode. Teams of 2-4 are grinding through their 9-day building sprint with access to mentors, partners, and up to $1M in partner bounties & prizes plus up to $10M in grants & investments. ETHDenver alumni include 1inch, Bankless, POAP, Harpie, and Covalent — so the track record speaks for itself.
AI agents dominate. From the expo floor:
AI agents were the biggest theme across vendor booths, with DeFi a close second
Injective hosted "Build Mode" powered by Chainlink — a developer-focused session on RWA tooling for institutional-grade DeFi, complete with networking and an infra panel with MoonPay
PrismaX ran a live robot teleoperation competition with a $1,000 prize — yes, actual robots at a blockchain conference
Playcambria had a booth in the Blockchain Arcade offering exclusive Bufficorn pets and arena tokens for IRL attendees
Tria was demoing panels on building the consumer crypto stack, with Mastercard's blockchain SVP on stage
A Quantum Summit kicked off with panels on quantum computing and blockchain intersections
The expo felt focused. As one Farcaster user noted: "Less vendors this year. But the vendors seemed more serious and focused, less of the 'we didn't have anything else going on' types."
Every ETHDenver has its memes. Here's what's hitting different this year:
The most viral ETHDenver content isn't about tech — it's about scams. Two major phishing operations went live this week:
Scam #1: The Fake VC Dinner. Scammers created a convincing "Shorooq Closed-Door Dinner Network" on Luma with AI-powered screening interviews, a premium-verified Telegram account, and a pixel-perfect fake Streamyard site (.ink instead of .com). The goal: get victims to download malware. As Harrison Frye warned: "The sophistication is insane."
Scam #2: The TECHNO NIGHT That Wasn't. A fake party listing on Luma for "TECHNO NIGHT" at Club Vinyl (a real venue, but not actually booked). Registrants got emails to "mint an NFT for entry" via a spoofed Moongate site that drained wallets. Result: dozens of confused attendees outside a closed venue on a cold Denver street. No party vibes. Empty wallets.
The lesson? If it requires a signature to RSVP, it's a scam. Use burner wallets. Verify URLs character by character. The scammers are using AI now too.
ETHDenver switched from badges to wristbands this year and people have feelings. Only speakers, vendors, and volunteers got badges. The masses got wristbands that "aren't as cool and aren't removable." The merch discourse continues.
The duck/goose-themed merch by Lovejoy and duckfacts.eth was the clear crowd favorite. Multiple people on Farcaster called it "the best merch at ETHDenver" — specifically a goose pin that apparently transcended blockchain tribal boundaries. 🪿
At 4:20 PM (nice), the Memethology x ETHDenver card trading session kicked off — physical and digital cards featuring "BUIDL City heroes, meme gods, and web3 legends." A TCG at a blockchain conference. We've come full circle.
One attendee reported seeing someone open Kalshi at ETHDenver and them "immediately losing any and all aura." The prediction market wars are real and they're fought at conferences.
"ETHDenver 2026 will be remembered as the year 'agentic finance' went from buzzword to infrastructure. Every protocol announcing agent transactions but nobody asking 'how do you verify the agent isn't a rug?'" — @0xbrainKID
Attendance: ~8,000-10,000 (down from 25K peak years, but up from 2,500 in 2020)
Venue: National Western Center — nicer than the old spot, but smaller
Market backdrop: BTC down ~28%, ETH down ~40%, altcoin selling pressure at five-year highs
Energy: Defiant
As ETHDenver founder John Paller told Decrypt: "ETH Denver has always benefited from bear markets. The noise-to-signal ratio is going to be much better. The people who are here are serious, and they care deeply about the future of Web3."
Both, but the builders are winning. Steve Moraco (ETHDenver team) noted it has "by far the highest ratio of people carrying open laptops around and building" of any conference he's been to. And Keone Hon from Monad summed it up simply: "Vibes immaculate."
0xJoshua (SporkDAO) had the definitive take on the bear market question: "Bear or bull, the BUIDLers gonna BUIDL."
27 side events in a single night. Highlights:
Doge House After Dark at Meow Wolf — called "definitely the best party at ETHDenver this year" by multiple attendees
Hypernative's mansion party — crypto's top-tier VCs and founders at Denver's largest private mansion
Pizza DAO kickoff — "pizza heaven... I thought it would run out but it didn't stop flowing"
Vibez Lounge Happy Hour with DJ ANASTAZJA
DeFi Party — where the OGs gathered
XRP racing sims — racing simulators running all night, "top vibes"
Blockspace Church by WebZero & Polkadot — one of the dopest side events according to attendees
Worth noting: ETHDenver doubled down on wellness this year with the Zen Zone near the entrance — art and mental wellness before the panels and networking begin. In a space where burnout is real, this matters. NFT CLT co-founder Tony Bravado: "You have AI, you have wellness, all together, and it just feels good to be here."
Scaling Ethereum Summit continues on main stage
Bitcoin Summit on the Futurllama Stage — Robin Linus on BITVM3 and garbled circuits
Trading Summit on New France Village Stage
BUIDLathon demos as teams enter final sprint
Buffitank Pitchfest — startups pitching to VCs
More side events: Nads Happy Hour (Monad), Multichain Day, various ecosystem meetups
Jesse Pollak discussing the future of Base
Watch for the SEC innovation exemption ripple effects in RWA/DeFi conversations
ETHDenver 2026 Day 2 proved that the best conferences happen when the tourists go home. Smaller crowd, higher signal, real builders doing real work. The SEC showed up with actual policy proposals. Vitalik set the philosophical direction. The EF engineers got into the technical weeds. And somewhere in Denver, someone is still looking for that TECHNO NIGHT party at Club Vinyl.
This isn't a conference running on hopium. It's a community running on conviction.
See you on the builder floor. 🦬
