📋 Summary

The Dawn of the Golden Age of Crypto Building

We have officially entered the "golden age of crypto building." According to Jesse Pollock, founder of Base, the foundational infrastructure work is finally complete. The industry has moved past the experimental phase, and the focus is now squarely on entrepreneurs leveraging these tools to create "10x impact" for businesses and building consumer experiences that were previously impossible. The current landscape is defined by maturity in key areas: chains have scaled, stablecoins have emerged as a powerful utility, and wallets have become significantly simpler.

The Shift to FinTech 3.0

Pollock draws a distinction between the historical progression of financial technology:

  • FinTech 1.0 (90s): The era of companies like PayPal, where consumers first grew comfortable with online payments.
  • FinTech 2.0 (Last decade): Startups building on top of legacy systems to deliver friendlier user experiences.
  • FinTech 3.0 (The current opportunity): The potential to "rewrite it all" from the ground up using programmable software platforms where money is native—specifically, crypto.

Solving the Scalability and Regulatory Hurdles

Historically, crypto suffered from being "slow and expensive," creating a barrier to entry where gas fees could cost more than the transaction itself. The industry has reached a "broadband moment" where costs have dropped from dollars to fractions of a cent, thanks to the evolution of Layer 2 solutions. Base, for instance, acts as an "HOV lane" on top of Ethereum, compressing millions of transactions to drive efficiency while maintaining the decentralization and censorship resistance of the L1 base layer.

Furthermore, the regulatory environment is finally shifting. Previously, startups were forced to spend more on lawyers than engineers, which effectively "chilled" innovation. With emerging clarity—such as the Genius Act and various stablecoin policies—the "rules of the road" are becoming clearer, allowing founders to focus on product-market fit rather than legal survival.

The Killer Use Case: Stablecoins and Programmable Money

Stablecoins have evolved from a niche asset to nearly $200 billion in market value. Pollock emphasizes that they provide "programmable dollars" to anyone globally, regardless of their location. This is a game-changer for entrepreneurs in regions with unstable local currencies, as it allows them to save, borrow, and transact in dollars without needing access to traditional banking systems. Beyond the dollar, there is a burgeoning opportunity for builders to create local-currency stablecoins (like the Brazilian Real or Nigerian Naira), enabling local economies to benefit from crypto-native efficiencies.

Disrupting Incumbents with Smart Contracts

Pollock highlights the collaboration with Shopify as a prime example of why this technology matters. By translating complex, million-line legacy systems—involving escrow, taxes, and tariffs—into a thousand-line smart contract, businesses can achieve massive operational efficiency. The mental model for founders is clear: identify where intermediaries currently extract value in traditional networks and use this new "open platform" to mediate those same transactions 10 times cheaper and faster.

The Intersection of AI and Crypto

Pollock and the Y Combinator team see a natural synergy between AI and crypto. AI agents require a "native substrate" to operate, and crypto provides the ideal environment for these agents to transact. Furthermore, in an era where AI-generated content makes it difficult to distinguish reality, crypto offers a method for "authenticity and verification," ensuring that data and assets are traceable and immutable.

Conclusion: A Call to Builders

For technical founders, the advice is to move past the "speculation" phase and focus on solving real problems for everyday people. The best teams are those that "work hard, do the right thing, and push boundaries." Y Combinator and Coinbase are actively seeking these "based" founders who understand the technology deeply but apply it to solve tangible pain points. As Pollock concludes, the infrastructure is ready, the barriers are lowering, and the time to build is now.

📖 Transcript

We've entered the golden age of crypto building, where we finally have the tools, and now it's about entrepreneurs coming in and saying how do we use these tools to make 10x impact for businesses or to build new consumer experiences that were previously completely impossible?
And the moment is now to break through, because we've done the infrastructure work.
The tools are in place, the stable coins, the chain, and now it's about putting it together into that magical experience that grows like wildfire across the world.
I'm really excited to be joined here today by Jesse Pollock.
Jesse is the founder of Base, which started life as Coinbase's blockchain but has since expanded into essentially the everything app for crypto.
You can use Base to trade crypto, store your own crypto and build community with other people in crypto.
