Aave Founder: What Is the Secret of the DeFi Lending Market?
When on-chain lending becomes significantly cheaper than traditional lending in end-to-end operations, mass adoption is not a question—it is inevitable.

On-chain lending began around 2017 as a fringe experiment tied to crypto assets. Today, it has evolved into a market exceeding $100 billion—primarily driven by stablecoin lending, secured by crypto-native collateral such as Ethereum, Bitcoin, and their derivatives. Borrowers unlock liquidity via long positions, execute leveraged loops, and engage in yield arbitrage. What matters is not creativity, but validation. Behavior over the past few years shows that smart-contract-based automated lending already possessed genuine demand and real product-market fit—long before institutions took notice.
Crypto markets remain volatile. Building lending systems atop the most dynamic assets currently available forces on-chain lending to confront risk management, liquidation, and capital efficiency head-on—rather than hiding them behind policy or human discretion. Without crypto-native collateral, we could never have seen just how powerful fully automated on-chain lending truly is. The key isn’t cryptocurrency as an asset class—it’s the cost-structure transformation enabled by decentralized finance.
Why On-Chain Lending Is Cheaper
On-chain lending is cheaper not because it’s new technology, but because it eliminates layers of financial waste. Today, borrowers can access stablecoins on-chain at roughly 5% annualized cost, while centralized crypto lenders charge 7%–12% interest plus fees, service charges, and various add-ons. When conditions favor borrowers, choosing centralized lending isn’t merely conservative—it’s irrational.
This cost advantage doesn’t stem from subsidies, but from capital aggregation within open systems. Permissionless markets are structurally superior to closed ones in aggregating capital and pricing risk—because transparency, composability, and automation drive competition. Capital flows faster; idle liquidity is penalized; inefficiencies are exposed in real time; innovation spreads instantly.
When new financial primitives like Ethena’s USDe or Pendle emerge, they absorb liquidity across the entire ecosystem—and expand the usage of existing primitives (e.g., Aave)—without requiring sales teams, reconciliation processes, or back-office departments. Code replaces management overhead. This isn’t incremental improvement—it’s a fundamentally different operating model. All structural cost advantages flow directly to capital allocators—and, more importantly, to borrowers.
Every major transformation in modern history follows the same pattern: heavy-asset systems become light-asset systems; fixed costs become variable costs; labor becomes software; centralized scale replaces local duplication; excess capacity transforms into dynamic utilization. At first, these changes look bad. They serve non-core users (e.g., crypto lending instead of mainstream use cases), compete on price before quality improves, and appear unserious until they scale beyond the capacity of incumbents to respond.
On-chain lending fits this pattern precisely. Early users were mostly niche crypto holders. UX was poor. Wallets felt alien. Stablecoins didn’t touch bank accounts. Yet none of that mattered—because costs were lower, execution faster, and access global. As everything else improved, accessibility followed.
What Comes Next
During bear markets, demand falls and yields compress—revealing a deeper dynamic: capital in on-chain lending is always competing. Liquidity doesn’t sit idle due to quarterly committee decisions or balance-sheet assumptions. It continuously reprices in transparent environments. Few financial systems are this ruthless.
On-chain lending doesn’t lack capital—it lacks borrowable collateral. Most on-chain lending today simply recycles the same collateral for the same strategies. This isn’t a structural limitation—it’s temporary.
Cryptocurrencies will continue generating native assets, productive primitives, and on-chain economic activity—expanding the scope of lending. Ethereum is maturing into a programmable economic resource. Bitcoin is consolidating its role as economic energy storage. Neither is final.
If on-chain lending is to reach billions of users, it must absorb real economic value—not just abstract financial concepts. The future lies in combining autonomous crypto-native assets with tokenized real-world rights and obligations—not to replicate traditional finance, but to operate it at extremely low cost. This will catalyze the replacement of legacy financial backends with DeFi.
What’s Broken About Lending
Lending is expensive today not because capital is scarce—it’s abundant. Prime capital clears at 5%–7%. Venture capital clears at 8%–12%. Borrowers still pay high rates because everything surrounding capital remains inefficient.
Origination is bloated by customer acquisition costs and lagging credit models. Binary underwriting forces high-quality borrowers to overpay, while low-quality borrowers receive subsidies until default. Servicing remains manual, compliance-heavy, and slow. Incentives are misaligned at every layer: those pricing risk rarely bear it; brokers don’t absorb defaults; originators offload risk exposure immediately. Everyone gets paid regardless of outcome. Defective feedback mechanisms—not risk itself—are the true cost of lending.
Lending hasn’t been disrupted because trust still overrides UX, regulation constrains innovation, and losses mask inefficiency until they explode. When lending systems collapse, consequences are often catastrophic—reinforcing conservatism over progress. Thus, lending still looks like an industrial-age product awkwardly bolted onto digital capital markets.
Breaking the Cost Structure
Unless origination, risk assessment, servicing, and capital allocation become fully software-native and on-chain, borrowers will keep overpaying—and lenders will keep rationalizing those costs. The solution isn’t more regulation or marginal UX improvements. It’s breaking the cost structure: automation replacing process, transparency replacing discretion, determinism replacing reconciliation. That’s the disruption DeFi brings to lending.
When end-to-end on-chain lending becomes demonstrably cheaper than traditional lending, adoption won’t be a question—it’ll be inevitable. Aave emerged precisely in this context, serving as the foundational capital layer for a new financial backend—from fintech firms and institutional lenders to consumers.
Lending will become the most empowering financial product—not because of its mechanics, but because DeFi’s cost structure enables fast-moving capital to flow precisely where it’s needed most. Abundant capital creates abundant opportunity.
