In the rapidly evolving world of decentralized finance (DeFi), few projects have managed to transition as successfully as Aave—from its early days as ETHLend to becoming one of the most influential lending protocols in the blockchain space. Originally launched under the name LEND, this token has undergone a significant transformation, both technically and functionally, aligning with the broader rebranding of ETHLend into Aave.
This article explores the journey of LEND, its role in the DeFi ecosystem, the mechanics behind Aave’s innovative lending model, and what investors and users should know about its historical performance and future potential.
The Evolution from ETHLend to Aave
In September 2018, ETHLend officially rebranded to Aave, marking a pivotal shift in its vision and technological approach. The name "Aave" comes from Finnish, meaning “ghost”—a symbolic representation of transparency, invisibility of intermediaries, and seamless financial interactions within a decentralized environment.
Headquartered in London, UK, Aave was built by a team of 18 forward-thinking developers and blockchain enthusiasts who aimed to revolutionize peer-to-peer (P2P) lending through smart contract automation and open-source innovation.

From Peer-to-Peer to Pool-Based Lending
While ETHLend started as a decentralized P2P lending platform, allowing users worldwide to borrow or lend using cryptocurrency as collateral, it soon evolved beyond direct matching. One of the most significant upgrades came with the introduction of Decentralized Lending Pools (DLPs)—a system that replaced traditional P2P structures with liquidity pools.
This new model allows users to deposit assets into shared pools rather than directly funding individual borrowers. As a result:
- Lenders earn passive income via interest accrued from borrowers.
- Borrowers can access funds instantly without waiting for a direct match.
- Assets are secured through over-collateralization and enforced via smart contracts.
The DLP system supports over 150+ ERC-20 tokens as collateral, including major cryptocurrencies like ETH, BTC, DAI, USDT, and various stablecoins, significantly expanding accessibility and flexibility.
Understanding the Role of LEND Token
Before the migration to Aave v2, LEND was the native utility token powering the ecosystem. Although LEND has since been swapped 1:100 for the new AAVE token, understanding its original purpose helps clarify the foundation upon which Aave’s governance and incentive structure was built.
Core Utilities of LEND (Pre-Migration)
- Staking & Passive Income: Users could stake LEND tokens in lending pools to earn yield on their holdings.
- Fee Discounts & Incentives: Holding LEND provided reduced fees across platform transactions.
- Governance Participation: Token holders gained voting rights on protocol upgrades, such as adding new collateral types or adjusting interest rate models.
- Security Mechanism: A portion of transaction fees was used to buy back and burn LEND tokens, creating deflationary pressure over time.
Although LEND is no longer active post-migration, its legacy lives on through AAVE, which retains similar—yet enhanced—governance and economic functions.
Aave Pay: Bridging Crypto and Real-World Spending
One of the standout features introduced during the ETHLend era was Aave Pay, a service designed for European users seeking to spend their crypto holdings in everyday life.
With Aave Pay, users can:
- Use cryptocurrencies like LEND, DAI, BTC, ETH, ADA, LTC, BCH, XLM, XRP, USDT, KCS, and BNB to make payments in fiat currency (currently EUR).
- Receive loan disbursements directly into their bank accounts.
- Cash out crypto without navigating complex exchange procedures—just a single transaction.
This integration marked an early step toward mainstream adoption, demonstrating how DeFi applications could serve real-world financial needs beyond speculation and trading.
Decentralized Lending Pools: Innovation at Scale
The shift from P2P lending to decentralized liquidity pools was more than just a technical upgrade—it represented a fundamental rethinking of how trustless finance could scale.
Key Advantages of Aave’s DLP Model
- Flexible Interest Rates: Borrowers can switch between fixed and variable interest rates based on market conditions and personal preference.
- Open Source Protocol: Developers can build on top of Aave’s infrastructure using its public API and smart contract ABIs.
- Non-Custodial Security: Users retain full control of their funds at all times; no centralized entity holds custody.
- Flash Loans: Aave pioneered flash loans—unsecured loans that must be borrowed and repaid within a single blockchain transaction—enabling advanced trading strategies like arbitrage and collateral swapping.
These innovations positioned Aave as a leader in DeFi lending, attracting billions in total value locked (TVL) across multiple blockchain networks.

Frequently Asked Questions (FAQ)
Q: What happened to the LEND token?
A: LEND was phased out in 2020 when Aave launched its V2 protocol. All LEND holders were required to swap their tokens for the new AAVE token at a ratio of 100:1. The migration enhanced security, governance capabilities, and laid the foundation for future protocol developments.
Q: Can I still use LEND today?
A: No. LEND is no longer functional within the Aave ecosystem after the migration. Any remaining LEND tokens should have been converted to AAVE. Unswapped tokens hold no utility in current DeFi applications.
Q: Is Aave safe for lending and borrowing?
A: Aave employs robust security measures including over-collateralization, liquidation mechanisms, regular audits by top firms like Trail of Bits and ConsenSys Diligence, and a bug bounty program. However, as with all DeFi platforms, users should understand smart contract risks and market volatility before participating.
Q: How does Aave generate returns for lenders?
A: When users deposit assets into Aave’s liquidity pools, they receive aTokens (e.g., aDAI, aUSDC), which accrue interest in real-time based on supply and demand dynamics. The interest comes from borrowers paying fees to use those funds.
Q: On which blockchains does Aave operate?
A: Aave is deployed across multiple chains including Ethereum, Polygon (formerly Matic), Avalanche, Optimism, Arbitrum, and others—enabling cross-chain liquidity and lower transaction costs depending on network choice.
Q: What makes Aave different from other DeFi lending platforms?
A: Aave stands out due to its innovation in flash loans, rate switching, credit delegation, and its strong focus on open-source development and community governance. Its evolution from ETHLend also reflects a long-term commitment to user-centric improvements.
Looking Ahead: The Future of DeFi Lending
As decentralized finance continues to mature, platforms like Aave are setting benchmarks for scalability, usability, and innovation. While LEND may be retired, its journey exemplifies how blockchain projects can adapt and grow in response to changing market demands.
With ongoing developments such as Aave Arc (for institutional lending) and GHO, Aave’s native stablecoin, the protocol continues pushing boundaries in permissionless finance.
Whether you're interested in earning yield on idle crypto assets or exploring advanced DeFi strategies like flash loans, understanding the roots of LEND and the evolution into Aave provides valuable context for navigating today’s digital economy.
