The world of decentralized finance (DeFi) is at a pivotal moment—one shaped by innovation bottlenecks, shifting user priorities, and the growing tension between decentralization and usability. Few figures understand this landscape better than Andre Cronje (AC), the visionary builder behind Yearn Finance, Solidly, Fantom, and now Sonic. In a revealing conversation from The DCo Podcast, AC shares candid insights into the realities of constructing in Web3 today.
From regulatory battles with the SEC to the stagnation of DeFi primitives, from the erosion of composability to the future of user experience, his reflections offer both a warning and a roadmap for developers and enthusiasts alike.
Navigating Regulatory Challenges in DeFi
Few builders have faced the legal spotlight as intensely as Andre Cronje. Despite operating from South Africa, developing locally, never fundraising, and not selling tokens, he still found himself in the crosshairs of the U.S. Securities and Exchange Commission (SEC).
"I thought I could focus on code," AC admits. "But regulatory and legal issues consumed a massive amount of my time."
His journey began with foundational projects like Yearn Finance and evolved into more complex systems like Solidly. However, it wasn’t technical hurdles that proved most draining—it was the relentless correspondence from regulators.
Initially, the SEC’s inquiries seemed routine: Who did you sell tokens to? How do you profit from the protocol? Simple questions with straightforward answers—he hadn’t sold any tokens, nor taken profits. But as the letters progressed, the tone shifted. By the fifth or sixth request, it was clear they understood DeFi deeply—and were looking for vulnerabilities.

AC realized he needed expert help. Without venture backing, he turned to his network and connected with Gabriel from Lex Node and later Steven Palley—both seasoned crypto legal minds. Their guidance was crucial, not just in content but in how responses were framed. Legal language matters; one misstep could redefine a protocol as a security under the Howey Test.
Eventually, the SEC pivoted their argument: even if no tokens were sold, perhaps the treasury itself constituted an investment contract. This demand—to prove a negative—felt impossible. "It’s like proving Santa Claus doesn’t exist," AC says wryly.
Thankfully, enforcement actions ceased months before a U.S. election cycle, bringing temporary relief. But the cost—three consecutive weeks spent solely gathering data, often nonexistent logs or third-party records—was staggering.
This experience underscores a harsh truth: in crypto, even permissionless builders aren't immune to centralized scrutiny.
Why DeFi Innovation Has Stalled
One of AC’s most striking claims? DeFi innovation has largely stalled since 2022.
While new products like Hyperliquid have emerged, they’re iterations—not new primitives. The foundational building blocks of DeFi remain largely unchanged: Uniswap V2’s x * y = k model still underpins much of the ecosystem due to its predictability and immutability.
But why hasn’t anyone replaced it?
“The market has shifted,” AC explains. “People no longer prioritize decentralization or immutability.”
In 2019–2020, DeFi attracted idealists—technologists passionate about self-custody and censorship resistance. Today’s participants? Mostly driven by token gains and yield chasing. Meme coins, NFTs, and liquidity mining lowered barriers to entry but also diluted philosophical commitment.
This shift creates a dangerous mismatch:
- Builders creating base-layer primitives need them to be immutable, so others can safely build atop them.
- Yet most new protocols are upgradable, making them risky dependencies.
- Result? Projects avoid composability altogether—building isolated AMMs or lending markets instead of leveraging existing ones.

And here lies the feedback loop:
More income-focused projects → Less immutable infrastructure → Fewer composable primitives → More isolated development.
True innovation requires builders who combine technical skill, creative vision, and financial independence—a rare trifecta. Most developers need funding, which brings VC pressure focused on ROI, not long-term protocol health.
Even when teams self-fund (like Hyperliquid), they’re outliers. For most, six months without income isn’t feasible.
“Real builders struggle to get funded,” AC notes. “Meanwhile, the 99th fork of a known project raises $50M because someone knows the right people.”
Until this incentive misalignment is resolved, breakthrough innovation will remain scarce.
The Missing Primitives: What’s Next for DeFi?
Despite stagnation, AC believes DeFi is still in its infancy.
1. Advanced AMMs & Dynamic Liquidity Models
We’re stuck on basic curves like constant product (x*y=k) and stableswap. Solidly introduced x^3*y, but progress has halted. With faster blockchains enabling dynamic liquidity market makers (DLMMs), there's room for adaptive pricing models and novel liquidity provisioning strategies.
2. On-Chain Oracles
A major missing piece. Fear of exploits keeps DeFi from embracing reliable price feeds for volatility, implied volatility, or order book depth. But secure implementations exist—whether fully on-chain designs or off-chain oracles using zero-knowledge proofs.
Once robust oracles are live:
- Black-Scholes pricing models become feasible
- European and American options can be built
- Delta-neutral strategies emerge
- True perpetual contracts unlock
In traditional finance, derivatives dominate trading volume—yet they're nearly absent on-chain. The path forward is clear: data first, then complexity.
3. Insurance Primitives
Another glaring gap. While protocols like Nexus Mutual exist, we lack standardized, scalable insurance layers that can protect against smart contract failures, oracle manipulation, or systemic risk.
These aren’t just add-ons—they’re foundational to trustless finance.
Balancing Decentralization and User Experience
Is true decentralization compatible with great UX? AC’s answer: not currently—and likely never perfectly.
True decentralization means:
- Running your own node
- Interacting via CLI
- Managing private keys and gas fees
Globally, perhaps 10,000 people can do this comfortably.
Great UX means:
- One-click sign-in (Face ID, Google)
- No wallet setup
- No gas fees
Platforms like Solana apps deliver this—but at the cost of centralization. Once you deposit funds into Hyperliquid or similar platforms, your assets are no longer self-custodied.
AC’s approach? Build both:
- Start with fully decentralized, CLI-accessible contracts
- Add abstraction layers: APIs, gasless transactions, signature wallets
- Deliver a final interface where users simply click buttons—unaware they're interacting with blockchain
This mirrors historical tech evolution: early computing required deep expertise; today’s smartphones hide complexity behind intuitive UIs.
“We’re manually doing what will eventually be native,” AC says. “Like early programmers automating repetitive tasks.”
Ethereum’s upcoming Pectra upgrade may accelerate this by making account abstraction and native gas sponsorship standard—eliminating MetaMask for everyday users.
The goal? Users shouldn’t know they’re using blockchain—just that the app works seamlessly.
Ethereum’s Crossroads: Innovation vs. Inertia
AC doesn’t mince words: L2s are premature and fragmenting the ecosystem.
Yes, scaling is necessary—but Ethereum operates at only ~2% of its theoretical capacity. Chains like Solana and Sonic prove high throughput is possible at Layer 1 without sacrificing security.
Instead of optimizing base-layer performance, Ethereum has offloaded scalability to L2s—many of which use centralized sequencers and extract value via MEV.
“They’re not composable sidechains—they’re profit-driven silos.”
Why hasn’t Ethereum improved its core?
Because it’s entered corporate maturity: once agile and experimental, now burdened by governance committees, audits, and risk aversion.
Case in point: AC’s team at Sonic rebuilt the EVM database (SonicDB), achieving:
- 8x higher throughput
- 98% reduction in storage
The fix? Replace generic databases (LevelDB) with a flat-file system optimized for EVM’s simple key-value structure. Low-risk, high-reward—but unlikely to land on Ethereum soon due to fear of change.
“They’d lose SQL query capability,” AC notes. “But nobody runs SQL on chain at scale anyway.”
Ethereum’s research (e.g., EIPs on account abstraction) remains visionary—but implementation lags years behind.
Advice for New Builders in Crypto
After years on the front lines, AC offers hard-won advice:
- Build Publicly: Share code on GitHub, post updates on social media. Invite scrutiny early—when bugs cost $50, not $50M.
- Prioritize Security: Partner with firms like Chainalysis or SlowMist for audits and red-team drills.
- Expect Crisis: Many quit after their first exploit. If you can’t handle pressure, this space isn’t for you.
- Find Your Balance: Decide how much decentralization your users truly need vs. what UX they demand.
“Open building is a filter,” AC says. “You’ll quickly learn if you belong here.”
