Just released the latest Endgame with @Austin_Federa!

For many years, Austin had a similar role in the world of Solana as I did in Ethereum, sitting in the seat of storytelling and GTM.

When we got to know each other at @buidl_conf through mutual friends @ekang426 and @ilblackdragon it reaffirmed I had to invite the person who'd been on this longtime, parallel path to sit down on the show.

Austin is a wonderful conversationalist and unique thinker, and we discuss the trajectory of crypto, the perspectives we came from in Solana and Ethereum, and wading through nihilism to buidl what's next.

It's a great episode, and I hope you enjoy it.

Can a popup city for smart people prevent WW3?

On the latest Endgame,@amandacassatt and @timourxyz discuss how his collaboration with @VitalikButerin evolved into a new identity group for today's brightest minds to exit together from nationalism and militarization.

Increíble: @ICBCArgentina emitió una tarjeta a mi nombre, la envió a una dirección que no es mía, hubo consumos fraudulentos y cerraron la investigación sin explicaciones - solo le tiraron la pelota @MastercardArg . Ya denunciado ante el @BancoCentral_AR.

We’re excited to launch our capital arm, 5HTP!

5HTP is a building block for Serotonin molecules. That’s how we see capital, as a precursor for our mission to take shape.

For years we’ve been quietly investing in venture and liquid deals with a long-term view towards whether they accelerate that mission, asking each time, “Does this help bring the world onchain?”

We see traction with the ultra-aligned model blending investment with services to help the strongest projects GTM. And as we increasingly work with the largest enterprises and institutions in the industry, that network will be immensely valuable to the startups we support.

5HTP is live today with positions including Ethereum, @SkyEcosystem, @aave, @maplefinance, @centrifuge, @Etherealize_io, and select generational companies like @bryan_johnson's Blueprint, and @xai.

Builders of breakthrough technologies: let’s talk.

Thesis: incentives = market design and the edge is analytics-first. Use game theory to set best-response depth, screen capital with caps + vesting, and explore at the edges of a data-defined optimal.

Introducing Dynamic zk-SNARKs—a breakthrough from the Lagrange research team Weijie Wang, @chbpap, @s_shravan, and @dipapadopo

Dynamic zk-SNARKs mark a major step forward in making real-time, updatable cryptographic proofs a reality

Here’s what that means and why it matters 🧵

[LAGRANGE @lagrangedev]

Lagrange is partnering with @NVIDIA to ensure that the AI revolution is 𝘃����𝗿𝗶𝗳𝗶𝗮𝗯𝗹𝗲 and 𝘀𝗮𝗳𝗲.

World, please meet Sero!

Our product team spent 18 months obsessively solving a huge problem: connecting crypto’s people.

Existing tools weren't quite right. X is for shouting from rooftops. LinkedIn is… yeah. Luma is limited. Conferences are popular but often lack ROI.

So we built the Serotonin Platform, web3’s missing "people layer" starting with events. What started as a tool to help our clients became crypto’s #1 side events list, mapping 500k+ connections and tracking 16k events across 60 countries, growing organically to thousands of users.

Now out of beta with its official launch and new name, Sero introduces even more: see who's in your city, search people by need (eg, finding VCs, partnering with DeFi apps), and natively host events.

Instead of starting with an arbitrary constraint like 180 characters, we started with a mission to serve a specific community: our own, with the goal of accelerating the growth of the space by organizing web3's people layer.

Check out https://t.co/ELABqvDf52, sign up, and please send feedback as we keep iterating. Excited to announce some huge partnerships soon. Think top crypto foundations and major conferences!

Do token airdrops actually work?

Our data team analyzed the Zora airdrop, and this is what we found:

▶️~$20M tokens sent to 526K+ wallets

▶️Only 0.7% (3,600 wallets) bought additional tokens afterward (~$3.5M spent, recouping just 17.5%)

▶️Of recipients, active wallets rose sharply from ~20K (one week pre-airdrop) to ~74K (airdrop week), then rapidly declined. 81.5% made zero subsequent transactions

▶️Just 0.3% remained highly engaged long-term (10+ tx post-airdrop)

Conclusion?

Many broad airdrops generate brief attention but rarely sustained engagement. If they're primarily awareness plays, it's an extremely expensive marketing tactic. Targeting committed users likely offers superior ROI at lower cost. 💡

Disclaimer: We don’t know Zora’s internal objectives or KPIs, so this isn’t a commentary on their strategy. We’re just providing onchain insights to help inform your approach!
