Key Takeaways

Aave is a decentralized finance (DeFi) protocol that enables users to lend and borrow cryptocurrencies without intermediaries, using smart contracts on blockchain networks like Ethereum, where depositors earn interest and borrowers provide collateral.
Its core features include flash loans, which allow instant, collateral-free borrowing as long as repayment occurs in the same transaction, alongside options for stable or variable interest rates to suit different user needs.
Aave’s native token, AAVE, powers governance, staking for security, and fee reductions, making it integral to the ecosystem’s operation and growth.
Advantages include high liquidity through lending pools, multi-chain support for lower fees, and innovative risk management via health factors, though it comes with risks like smart contract vulnerabilities and market volatility.
As a leader in DeFi, Aave has expanded to networks like Polygon and Avalanche, fostering a vibrant community and partnerships that drive adoption in the broader crypto industry.

What Is Aave?

Aave is an open-source, decentralized lending protocol built on blockchain technology that allows users to deposit cryptocurrencies into liquidity pools to earn interest or borrow assets by providing collateral, all without relying on traditional banks or intermediaries, leveraging smart contracts for automated, trustless transactions.

Imagine you’re at a coffee shop, chatting with a friend about how banking could be revolutionized. That’s where Aave comes in—it’s like a peer-to-peer lending club, but on the blockchain. Originating from the Finnish word for “ghost,” Aave started as ETHLend in 2017, founded by Stani Kulechov, and rebranded to Aave in 2020 to emphasize its broader DeFi ambitions. The core concept revolves around creating efficient, permissionless money markets where anyone can lend or borrow crypto assets seamlessly. The ecosystem includes lending pools, flash loans for quick arbitrage, and governance through the AAVE token, which lets holders vote on protocol upgrades. Backed by a team of blockchain experts, Aave has grown into a multi-billion-dollar protocol, integrating with various chains to reduce costs and increase accessibility. It’s not just about lending; it’s about democratizing finance, much like how ride-sharing apps disrupted taxis.

Origins and Background

Aave’s journey began in the midst of the 2017 crypto boom, when traditional lending was clunky and centralized. It evolved from a simple P2P lending platform to a full-fledged DeFi powerhouse, with its V1 launch in 2020 introducing flash loans that shook up the industry.

Core Concept and Ecosystem

At its heart, Aave operates on liquidity pools where suppliers and borrowers interact via smart contracts. The ecosystem spans DeFi applications, including integrations with wallets, DEXs, and even real-world asset tokenization, making it a staple in the crypto lending space.

FAQs on Aave Basics

What makes Aave different from traditional banks? Unlike banks, Aave is decentralized—no single entity controls it, and everything runs on code, ensuring transparency and global access.
Is Aave only for experts? Nope, it’s user-friendly with interfaces like the Aave app, though beginners should start small to understand the risks.

Who Created Aave?

Stani Kulechov, a Finnish entrepreneur with a background in law and a passion for blockchain, founded Aave (originally ETHLend) in 2017. He assembled a team of developers, economists, and crypto enthusiasts, including names like Jordan Lazaro Gustave and Mika Antero, who brought expertise in smart contracts and finance. The project originated from Kulechov’s frustration with inefficient lending in crypto, inspired by the Ethereum ecosystem’s potential.

The whitepaper, released in 2017, outlined a peer-to-peer lending model using ERC-20 tokens. Key milestones include the 2017 ICO raising $16 million, the 2020 rebrand to Aave with flash loans, and expansions to Polygon in 2021 and Avalanche in 2022. By 2025, Aave has handled billions in loans, surviving market crashes like the 2022 bear market through robust governance. It’s like that startup story where a small team builds something that outpaces giants—think of it as the Uber of crypto lending.

Founding Team Background

Kulechov, often called a DeFi visionary, has spoken at conferences like Devcon, emphasizing open finance. The team includes advisors from ConsenSys, adding credibility.

Historical Milestones

From its ICO to V3 upgrades in 2023, which enhanced cross-chain functionality, Aave’s timeline shows steady innovation, with TVL (total value locked) peaking at over $20 billion during bull runs.

How Does Aave Work?

Picture Aave as a high-tech vending machine for loans: you put in crypto as collateral, select your borrowing terms, and out comes the loan—all automated. It runs on Ethereum’s blockchain, using smart contracts written in Solidity to handle lending and borrowing. No proof-of-work here; it leverages Ethereum’s proof-of-stake for efficiency.

Depositors add assets to pools, receiving aTokens (like interest-bearing receipts) that accrue value over time. Borrowers over-collateralize to mitigate risks, with interest rates fluctuating based on supply and demand—variable rates change with market conditions, while stable rates offer predictability but can adjust in extremes.

Flash loans are the star: borrow millions without collateral, but repay in the same block, or the transaction reverses. Security comes from the health factor, monitoring collateral vs. debt; drop below 1, and liquidation bots step in to sell assets and repay loans. Aave’s multi-chain setup on Polygon and Avalanche cuts gas fees, making it faster than pure Ethereum ops. Public keys let you interact openly, while private keys secure your wallet—lose them, and it’s like locking yourself out of your house forever.

Blockchain and Consensus Mechanisms

Aave piggybacks on Ethereum’s PoS, ensuring transactions are validated securely without energy-heavy mining. It’s all about efficiency in a decentralized world.

Smart Contracts and Technical Principles

Smart contracts automate everything, from interest calculations to liquidations. Think of them as self-executing agreements—code that enforces rules without a middleman.

Key Technical Features

aTokens: These grow in value as interest accrues, like a savings account on steroids.
Risk Management: Oracles feed real-time prices to prevent under-collateralization.

FAQs on Aave Mechanics

How safe are flash loans? Incredibly safe due to atomic transactions—if not repaid, nothing happens. It’s like a trial run with no commitment.
What if markets crash? The health factor protects the system by triggering liquidations, but users might lose collateral.

How Is New AAVE Created?

AAVE isn’t mined like Bitcoin; it’s a governance token with a fixed supply model. The total supply is capped at 16 million tokens, with about 14.8 million circulating as of 2025-08-20 14:02:10. New AAVE isn’t “created” per se—most were pre-allocated during the 2020 token migration from LEND to AAVE at a 100:1 ratio.

Instead, users earn AAVE through staking in the Safety Module, where they lock AAVE to backstop the protocol against shortfalls, receiving rewards from fees and emissions. The inflation model is minimal, with emissions tapering off; currently, it’s deflationary as fees buy back and burn AAVE. Rewards come from protocol fees (like borrowing interest), distributed to stakers. No endless minting here—it’s designed for scarcity, much like limited-edition sneakers that gain value over time.

Issuance and Staking Mechanisms

Staking AAVE in the Safety Module earns stkAAVE, which accrues rewards while providing insurance. It’s a way to participate without mining hardware.

Supply Limits and Rewards

With a hard cap, AAVE avoids hyperinflation. Rewards are performance-based, incentivizing long-term holders.

What Are the Use Cases of Aave?

Aave shines in DeFi, where users lend stablecoins like USDC to earn yields or borrow ETH against collateral for leverage. It’s perfect for cross-border transfers—no banks, just instant blockchain magic. In governance, AAVE holders vote on proposals, shaping the protocol’s future.

Flash loans enable arbitrage: spot a price difference on DEXs, borrow, trade, repay—all in seconds. NFTs? Collateralize them for loans without selling. It’s like using your art collection as a credit line. Real-world applications include yield farming, where farmers deposit into pools for optimal returns, or even institutional use for efficient capital deployment. Ever thought of borrowing crypto to short a market? Aave makes it seamless.

Editor's Note: Citrini7's cyberpunk-themed AI doomsday prophecy has sparked widespread discussion across the internet. However, this article presents a more pragmatic counter perspective. If Citrini envisions a digital tsunami instantly engulfing civilization, this author sees the resilient resistance of the human bureaucratic system, the profoundly flawed existing software ecosystem, and the long-overlooked cornerstone of heavy industry. This is a frontal clash between Silicon Valley fantasy and the iron law of reality, reminding us that the singularity may come, but it will never happen overnight.

The following is the original content:

Renowned market commentator Citrini7 recently published a captivating and widely circulated AI doomsday novel. While he acknowledges that the probability of some scenes occurring is extremely low, as someone who has witnessed multiple economic collapse prophecies, I want to challenge his views and present a more deterministic and optimistic future.

Never Underestimate "Institutional Inertia"

In 2007, people thought that against the backdrop of "peak oil," the United States' geopolitical status had come to an end; in 2008, they believed the dollar system was on the brink of collapse; in 2014, everyone thought AMD and NVIDIA were done for. Then ChatGPT emerged, and people thought Google was toast... Yet every time, existing institutions with deep-rooted inertia have proven to be far more resilient than onlookers imagined.

When Citrini talks about the fear of institutional turnover and rapid workforce displacement, he writes, "Even in fields we think rely on interpersonal relationships, cracks are showing. Take the real estate industry, where buyers have tolerated 5%-6% commissions for decades due to the information asymmetry between brokers and consumers..."

Seeing this, I couldn't help but chuckle. People have been proclaiming the "death of real estate agents" for 20 years now! This hardly requires any superintelligence; with Zillow, Redfin, or Opendoor, it's enough. But this example precisely proves the opposite of Citrini's view: although this workforce has long been deemed obsolete in the eyes of most, due to market inertia and regulatory capture, real estate agents' vitality is more tenacious than anyone's expectations a decade ago.

A few months ago, I just bought a house. The transaction process mandated that we hire a real estate agent, with lofty justifications. My buyer's agent made about $50,000 in this transaction, while his actual work — filling out forms and coordinating between multiple parties — amounted to no more than 10 hours, something I could have easily handled myself. The market will eventually move towards efficiency, providing fair pricing for labor, but this will be a long process.

I deeply understand the ways of inertia and change management: I once founded and sold a company whose core business was driving insurance brokerages from "manual service" to "software-driven." The iron rule I learned is: human societies in the real world are extremely complex, and things always take longer than you imagine — even when you account for this rule. This doesn't mean that the world won't undergo drastic changes, but rather that change will be more gradual, allowing us time to respond and adapt.

The Software Industry Has "Infinite Demand" for Labor

Recently, the software sector has seen a downturn as investors worry about the lack of moats in the backend systems of companies like Monday, Salesforce, Asana, making them easily replicable. Citrini and others believe that AI programming heralds the end of SaaS companies: one, products become homogenized, with zero profits, and two, jobs disappear.

But everyone overlooks one thing: the current state of these software products is simply terrible.

I'm qualified to say this because I've spent hundreds of thousands of dollars on Salesforce and Monday. Indeed, AI can enable competitors to replicate these products, but more importantly, AI can enable competitors to build better products. Stock price declines are not surprising: an industry relying on long-term lock-ins, lacking competitiveness, and filled with low-quality legacy incumbents is finally facing competition again.

From a broader perspective, almost all existing software is garbage, which is an undeniable fact. Every tool I've paid for is riddled with bugs; some software is so bad that I can't even pay for it (I've been unable to use Citibank's online transfer for the past three years); most web apps can't even get mobile and desktop responsiveness right; not a single product can fully deliver what you want. Silicon Valley darlings like Stripe and Linear only garner massive followings because they are not as disgustingly unusable as their competitors. If you ask a seasoned engineer, "Show me a truly perfect piece of software," all you'll get is prolonged silence and blank stares.

Here lies a profound truth: even as we approach a "software singularity," the human demand for software labor is nearly infinite. It's well known that the final few percentage points of perfection often require the most work. By this standard, almost every software product has at least a 100x improvement in complexity and features before reaching demand saturation.

I believe that most commentators who claim that the software industry is on the brink of extinction lack an intuitive understanding of software development. The software industry has been around for 50 years, and despite tremendous progress, it is always in a state of "not enough." As a programmer in 2020, my productivity matches that of hundreds of people in 1970, which is incredibly impressive leverage. However, there is still significant room for improvement. People underestimate the "Jevons Paradox": Efficiency improvements often lead to explosive growth in overall demand.

This does not mean that software engineering is an invincible job, but the industry's ability to absorb labor and its inertia far exceed imagination. The saturation process will be very slow, giving us enough time to adapt.

Redemption of "Reindustrialization"

Of course, labor reallocation is inevitable, such as in the driving sector. As Citrini pointed out, many white-collar jobs will experience disruptions. For positions like real estate brokers that have long lost tangible value and rely solely on momentum for income, AI may be the final straw.

But our lifesaver lies in the fact that the United States has almost infinite potential and demand for reindustrialization. You may have heard of "reshoring," but it goes far beyond that. We have essentially lost the ability to manufacture the core building blocks of modern life: batteries, motors, small-scale semiconductors—the entire electricity supply chain is almost entirely dependent on overseas sources. What if there is a military conflict? What's even worse, did you know that China produces 90% of the world's synthetic ammonia? Once the supply is cut off, we can't even produce fertilizer and will face famine.

As long as you look to the physical world, you will find endless job opportunities that will benefit the country, create employment, and build essential infrastructure, all of which can receive bipartisan political support.

We have seen the economic and political winds shifting in this direction—discussions on reshoring, deep tech, and "American vitality." My prediction is that when AI impacts the white-collar sector, the path of least political resistance will be to fund large-scale reindustrialization, absorbing labor through a "giant employment project." Fortunately, the physical world does not have a "singularity"; it is constrained by friction.

We will rebuild bridges and roads. People will find that seeing tangible labor results is more fulfilling than spinning in the digital abstract world. The Salesforce senior product manager who lost a $180,000 salary may find a new job at the "California Seawater Desalination Plant" to end the 25-year drought. These facilities not only need to be built but also pursued with excellence and require long-term maintenance. As long as we are willing, the "Jevons Paradox" also applies to the physical world.

Towards Abundance

The goal of large-scale industrial engineering is abundance. The United States will once again achieve self-sufficiency, enabling large-scale, low-cost production. Moving beyond material scarcity is crucial: in the long run, if we do indeed lose a significant portion of white-collar jobs to AI, we must be able to maintain a high quality of life for the public. And as AI drives profit margins to zero, consumer goods will become extremely affordable, automatically fulfilling this objective.

My view is that different sectors of the economy will "take off" at different speeds, and the transformation in almost all areas will be slower than Citrini anticipates. To be clear, I am extremely bullish on AI and foresee a day when my own labor will be obsolete. But this will take time, and time gives us the opportunity to devise sound strategies.

At this point, preventing the kind of market collapse Citrini imagines is actually not difficult. The U.S. government's performance during the pandemic has demonstrated its proactive and decisive crisis response. If necessary, massive stimulus policies will quickly intervene. Although I am somewhat displeased by its inefficiency, that is not the focus. The focus is on safeguarding material prosperity in people's lives—a universal well-being that gives legitimacy to a nation and upholds the social contract, rather than stubbornly adhering to past accounting metrics or economic dogma.

If we can maintain sharpness and responsiveness in this slow but sure technological transformation, we will eventually emerge unscathed.
