Original title: Aave Founder: Why is Lending the Most Empowering Financial Product?
On-chain lending began around 2017 as a fringe experiment related to crypto assets. Today, it has grown into a market worth over $100 billion, primarily driven by stablecoin lending, largely collateralized by crypto-native assets like Ethereum, Bitcoin, and their derivatives. Borrowers unlock liquidity through long positions, execute leverage loops, and engage in yield arbitrage. The key is not creativity, but validation. The behavior over the past few years has shown that automated lending based on smart contracts had genuine demand and true product-market fit long before institutions began to take notice.
The crypto market remains volatile. Building a lending system on top of the most dynamic existing assets forces on-chain lending to immediately address risk management, liquidation, and capital efficiency issues, rather than hiding them behind policies or human discretion. Without crypto-native collateral, it would be impossible to see just how powerful fully automated on-chain lending can be. The key is not cryptocurrency as an asset class, but the cost structure transformation brought 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 a cost of around 5%, while centralized crypto lending institutions charge interest rates of 7% to 12%, plus handling fees, service charges, and various additional costs. When conditions favor the borrower, choosing centralized lending is not only not conservative, it's irrational.
This cost advantage does not come from subsidies, but from capital aggregation in an open system. Permissionless markets are structurally superior to closed markets in pooling capital and pricing risk because transparency, composability, and automation drive competition. Capital moves faster, idle liquidity is penalized, and inefficiencies are exposed in real-time. Innovation spreads immediately.
When new financial primitives like Ethena's USDe or Pendle emerge, they absorb liquidity from the entire ecosystem and expand the use of existing financial primitives (like Aave) without the need for sales teams, reconciliation processes, or back-office departments. Code replaces management costs. This is not just an incremental improvement; it is a fundamentally different operational model. All advantages of the cost structure are passed on to capital allocators and, more importantly, to borrowers.
Every major transformation in modern history has followed the same pattern. Heavy-asset systems become light-asset systems. Fixed costs become variable costs. Labor becomes software. Centralized scale effects replace local duplication. Excess capacity is transformed into dynamic utilization. Change initially looks bad. It serves non-core users (e.g., lending for cryptocurrency, not mainstream use cases), competes on price before quality improves, and doesn't look serious until it scales to a point where existing players cannot cope.
On-chain lending fits this pattern exactly. Early users were mostly niche cryptocurrency holders. The user experience was poor. Wallets felt unfamiliar. Stablecoins didn't touch bank accounts. None of this mattered because the cost was lower, execution was faster, and access was global. As everything else improved, it became more accessible.
What Happens Next
During bear markets, demand falls, yields compress, revealing a more important dynamic. Capital in on-chain lending is always in competition. Liquidity does not stagnate due to quarterly committee decisions or balance sheet assumptions. It is constantly repriced in a transparent environment. Few financial systems are as relentless.
On-chain lending does not lack capital; it lacks collateral available for lending. Most on-chain lending today simply recycles the same collateral for the same strategies. This is not a structural limitation, but a temporary one.
Cryptocurrency will continue to generate native assets, productive primitives, and on-chain economic activity, thereby expanding the scope of lending. Ethereum is maturing into a programmable economic resource. Bitcoin is consolidating its role as a store of economic energy. Neither is a final state.
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 an extremely low cost. This will be the catalyst for replacing the backend of old finance with decentralized finance.
What's Wrong with Lending
Lending is expensive today not because capital is scarce. Capital is abundant. The clearing rate for quality capital is 5% to 7%. The clearing rate for risk capital is 8% to 12%. Borrowers still pay high interest rates because everything surrounding capital is inefficient.
The loan origination process is bloated with customer acquisition costs and lagging credit models. Binary approvals cause quality borrowers to overpay, while subprime borrowers receive subsidies until they default. Servicing remains manual, compliance-heavy, and slow. Incentives are misaligned at every layer. Those who price risk rarely actually bear the risk. Brokers do not bear default risk. Loan originators immediately sell their exposure. Everyone gets paid regardless of the outcome. The flaw in the feedback mechanism is the true cost of lending.
Lending has not been disrupted because trust trumps user experience, regulation stifles innovation, and losses mask inefficiencies until they explode. When lending systems fail, the consequences are often catastrophic, reinforcing conservatism over progress. Consequently, lending still looks like an industrial-era product crudely grafted onto digital capital markets.
Breaking the Cost Structure
Unless loan origination, risk assessment, servicing, and capital allocation become fully software-native and on-chain, borrowers will continue to overpay, and lenders will continue to rationalize these costs. The solution is not more regulation or marginal user experience improvements. It is breaking the cost structure. Automation replaces processes. Transparency replaces discretion. Certainty replaces reconciliation. This is the disruption decentralized finance can bring to lending.
When on-chain lending becomes significantly cheaper to operate end-to-end than traditional lending, adoption is not a question, it is inevitable. Aave was born in this context, capable of serving as the foundational capital layer for a new financial backend, serving the entire lending landscape from fintech companies to institutional lenders to consumers.
Lending will become the most empowering financial product simply because the cost structure of decentralized finance will enable fast-moving capital to flow into the applications that need it most. Abundant capital will breed abundant opportunity.
