Aave (AAVE) 是什麼？累計放款突破一兆美元、市佔逾半的去中心化借貸龍頭

Aave（AAVE）是市佔逾五成的去中心化借貸（DeFi Lending）龍頭協議，讓用戶無需銀行、無需信用審查，僅憑加密資產作為抵押品，即可在鏈上出借賺息或超額抵押借款。截至 2026 年，Aave 累計放款已突破一兆美元、鎖倉價值逾 250 億美元，並推出原生穩定幣 GHO 與機構級 RWA 借貸平台 Horizon。原生代幣 AAVE 為協議的治理代幣。

Aave 是目前規模最大的去中心化借貸協議，前身為 2017 年創立的 ETHLend，2020 年更名並轉型為採用「流動性資金池」模式的借貸平台。與傳統銀行不同，Aave 完全由智能合約運作——沒有信用審查、沒有貸款專員，只有程式碼、抵押品與數學。

其運作核心是「共享流動性池」：出借方存入加密資產（如 ETH、USDC、WBTC）賺取浮動利息，並取得可自動累積利息的憑證代幣（aToken）；借款方則存入價值更高的抵押品，超額借出所需資產。截至 2026 年，Aave 累計放款突破一兆美元、掌握逾 50% 的去中心化借貸市場，並部署於 Ethereum、Arbitrum、Base、Avalanche 等 10 條以上的區塊鏈。

Aave 的核心特色

1. 超額抵押借貸與閃電貸（Flash Loans）

Aave 的借貸建立在「超額抵押」之上，以確保系統償付能力：

超額抵押與清算： 借款人須維持抵押品價值高於借款的比率（LTV），一旦抵押品價值跌破清算門檻，協議會自動清算部分部位以維持系統健全。2025 年 Aave 處理了約 11 億美元、逾 10 萬次清算，且未產生任何壞帳。
閃電貸（Flash Loans）： Aave 首創的無抵押借貸——在同一個區塊內借出、使用並還款，若未於區塊結束前還清，整筆交易會如同從未發生般被還原。2025 年閃電貸經 Aave 處理的金額達 75 億美元，是套利、清算機器人與 DeFi 開發者的核心工具。

2. GHO：由借款鑄造的去中心化超額抵押穩定幣

GHO 是 Aave 的原生穩定幣，並非在交易所買賣後流通，而是由借款人存入抵押品後「鑄造」而生、還款時「銷毀」，供給隨借貸需求自然增減：

成長迅速： GHO 流通量從 2025 年初的約 3,500 萬美元，一年內成長約 1,400% 至逾 5 億美元。
內建收益： 逾半數 GHO 被存入「儲蓄型 GHO（sGHO）」賺取收益（年化約 5–7%），且所有 GHO 借款利息 100% 流入 Aave DAO 金庫，成為協議重要收入來源。
V4 核心： 在最新的 V4 架構中，GHO 成為整個系統的核心結算資產。

3. V4「Hub and Spoke」架構與機構級 Horizon

2026 年 3 月 30 日，Aave 於以太坊主網推出 V4 重大升級，核心是全新的「Hub and Spoke（樞紐與輻條）」架構：由中央「流動性樞紐」集中持有資產，各「輻條」市場則能有各自的抵押品種類、風險參數與清算規則，在不切割主流動性的前提下服務不同用戶。這也讓 Aave 首度支援固定利率借貸（對機構借款人尤其重要）。同時，其機構借貸平台 Horizon 讓傳統金融機構能以代幣化的美國國債、公司債等真實世界資產（RWA）作為抵押借出穩定幣，截至 2026 年 2 月已突破 10 億美元 RWA 鎖倉，合作對象包括 Circle、Ripple、VanEck、WisdomTree、Securitize 等。

代幣經濟學：固定總量、治理與「手續費開關」

AAVE 的代幣經濟聚焦於治理與協議安全：

固定總量： 總發行上限為 1,600 萬枚 AAVE，截至 2026 年約 1,516 萬枚流通。
治理與安全模組： AAVE 為治理代幣，持有者可對所有關鍵參數投票；質押 AAVE 至「安全模組（現升級為 Umbrella）」可為協議壞帳提供保障並賺取獎勵，但須承擔被罰沒（Slashing）的風險。
手續費開關與回購： Aave DAO 於 2025 年啟動「手續費開關」，將部分協議收入導向公開市場回購 AAVE；2025 年協議淨收入達 1.418 億美元（年增 57%）。惟需留意，回購已於 2026 年 4 月因一起市場事件而暫停，恢復時程尚待 DAO 決議。

投資 AAVE 需留意的市場隱患與重要風險揭露

Aave 擁有領先市佔與強勁現金流，但作為一項資產，投資人進場前仍應理性評估以下風險（以下資訊擷取日期：2026/08/19）：

智能合約與預言機風險： 儘管 Aave 是加密圈中經過最多審計的協議之一，DeFi 仍無法完全排除未知漏洞；2026 年 3 月一次預言機定價異常，即曾觸發約 2,700 萬美元的非必要清算。
借款人的清算風險： 借款採超額抵押，若抵押品價值下跌至門檻以下，部分部位將被強制清算，行情劇烈波動時尤須留意。
壞帳與系統性事件： DeFi 借貸在極端行情下仍可能累積壞帳；歷史上 Aave 曾在類似「銀行擠兌」的行情中，因利用率飆升而一度出現約 1.23 億美元的壞帳。回購於 2026 年 4 月暫停，正是與相關市場事件有關。
治理代幣的價值捕獲仰賴 DAO 決策： AAVE 的價值捕獲高度取決於手續費開關、回購節奏等治理決定，若回購長期暫停或收入下滑，代幣表現可能與協議規模成長背離。

Aave 憑藉領先市佔、強勁收入與高度審計的合約，穩居 DeFi 借貸龍頭。然而，請投資人交易前務必知悉上述智能合約與預言機風險、清算與壞帳風險，以及治理代幣價值捕獲的不確定性，理性評估自身的風險承受能力。

總結

Aave 成功地把「借貸」這項最古老的金融行為，重塑為完全由智能合約運作、全球無須許可即可參與的鏈上市場。從超額抵押借貸、首創的閃電貸，到原生穩定幣 GHO、V4 的 Hub and Spoke 架構與機構級 Horizon，Aave 已是 DeFi 借貸賽道無可爭議的領頭羊。不過，AAVE 作為治理代幣，其「協議成功」能否轉化為「代幣價值」，仍取決於手續費開關與回購等治理決策的走向。在配置這類資產時，建議密切關注 Aave 的收入與市佔、GHO 與 Horizon 的成長，以及回購機制的恢復進度。

What Is Aave (AAVE)? The Market-Leading Decentralized Lending Protocol With Over $1 Trillion in Cumulative Loans

Aave (AAVE) is the leading decentralized lending (DeFi lending) protocol, with over 50% market share, letting users lend to earn interest or borrow against crypto collateral on-chain—no bank, no credit check required. As of 2026, Aave has processed over $1 trillion in cumulative loans with over $25 billion in total value locked, and has launched its native stablecoin GHO and its institutional-grade RWA lending platform, Horizon. The native token, AAVE, is the protocol’s governance token.

Aave is the largest decentralized lending protocol, originally founded in 2017 as ETHLend and rebranded in 2020 into a “liquidity pool”-based lending platform. Unlike traditional banks, Aave runs entirely on smart contracts—no credit checks, no loan officers, just code, collateral, and math.

Its core is “shared liquidity pools”: lenders deposit crypto assets (like ETH, USDC, WBTC) to earn floating interest and receive interest-accruing receipt tokens (aTokens); borrowers post collateral worth more than they borrow to take out over-collateralized loans. As of 2026, Aave has processed over $1 trillion in cumulative loans, holds over 50% of the decentralized lending market, and is deployed across 10+ blockchains including Ethereum, Arbitrum, Base, and Avalanche.

Core Features of Aave

1. Over-Collateralized Lending and Flash Loans

Aave’s lending is built on “over-collateralization” to ensure system solvency:

Over-Collateralization and Liquidation: Borrowers must keep their collateral value above the loan ratio (LTV); if collateral value falls below the liquidation threshold, the protocol automatically liquidates part of the position to keep the system solvent. In 2025, Aave processed roughly $1.1 billion across 100,000+ liquidation events with zero bad debt.
Flash Loans: Aave’s pioneering uncollateralized loans—borrow, use, and repay within a single block; if not repaid before the block finalizes, the entire transaction is reverted as if it never happened. Flash loans processed $7.5 billion through Aave in 2025, serving as a core tool for arbitrageurs, liquidation bots, and DeFi developers.

2. GHO: A Decentralized, Over-Collateralized Stablecoin Minted by Borrowing

GHO is Aave’s native stablecoin—not bought and circulated on an exchange, but “minted” when borrowers deposit collateral and “burned” on repayment, with supply expanding and contracting with borrowing demand:

Rapid Growth: GHO circulating supply grew roughly 1,400% in a year, from about $35 million in early 2025 to over $500 million.
Built-In Yield: More than half of GHO is deposited into “Savings GHO (sGHO)” to earn yield (~5–7% APY), and 100% of GHO borrow interest flows to the Aave DAO treasury, serving as a key revenue source.
Core of V4: In the latest V4 architecture, GHO becomes the core settlement asset for the entire system.

3. The V4 “Hub and Spoke” Architecture and Institutional-Grade Horizon

On March 30, 2026, Aave launched its major V4 upgrade on Ethereum mainnet, centered on a new “Hub and Spoke” architecture: a central “Liquidity Hub” holds assets centrally, while individual “Spoke” markets can have their own collateral types, risk parameters, and liquidation rules—serving different users without fragmenting the main liquidity. This also lets Aave support fixed-rate loans for the first time (especially important for institutional borrowers). Meanwhile, its institutional lending platform Horizon lets traditional financial institutions borrow stablecoins against tokenized real-world assets (RWAs) like U.S. Treasuries and corporate bonds, surpassing $1 billion in RWA TVL by February 2026, with partners including Circle, Ripple, VanEck, WisdomTree, and Securitize.

Tokenomics: Fixed Supply, Governance, and the “Fee Switch”

AAVE’s token economics focus on governance and protocol security:

Fixed Supply: The maximum supply is 16 million AAVE, with roughly 15.16 million circulating as of 2026.
Governance and Safety Module: AAVE is a governance token; holders vote on all key parameters. Staking AAVE into the “Safety Module” (now upgraded to Umbrella) backstops protocol bad debt and earns rewards, but carries slashing risk.
Fee Switch and Buybacks: The Aave DAO activated a “fee switch” in 2025, directing part of protocol revenue toward buying back AAVE on the open market; 2025 net revenue reached $141.8 million (+57% YoY). Note, however, that buybacks were paused in April 2026 following a market incident, with the resumption timeline pending a DAO decision.

Market Risks and Key Disclosures to Note Before Investing

Aave has a leading market share and strong cash flow, but as an asset, investors should rationally assess the following risks before entering (information as of: 2026/08/19):

Smart Contract and Oracle Risk: Although Aave is one of the most-audited protocols in crypto, DeFi cannot fully rule out unknown vulnerabilities; a March 2026 oracle pricing glitch triggered roughly $27 million in unjustified liquidations.
Borrower Liquidation Risk: Borrowing is over-collateralized, so if collateral value drops below the threshold, part of the position is forcibly liquidated—especially a concern during sharp market swings.
Bad Debt and Systemic Events: DeFi lending can still accumulate bad debt in extreme conditions; historically, Aave once saw roughly $123 million in bad debt during a “bank run”-like event as utilization spiked. The April 2026 buyback pause was related to such a market incident.
Governance-Dependent Value Capture: AAVE’s value capture depends heavily on governance decisions like the fee switch and buyback cadence; if buybacks stay paused long-term or revenue declines, token performance may diverge from protocol growth.

With its leading market share, strong revenue, and heavily audited contracts, Aave sits firmly atop the DeFi lending sector. Nonetheless, investors should be fully aware of the risks above—smart contract and oracle risk, liquidation and bad-debt risk, and the uncertainty of governance-token value capture—and rationally assess their own risk tolerance before trading.

Summary

Aave has successfully reinvented “lending”—one of finance’s oldest activities—as an entirely smart-contract-run, permissionless on-chain market that anyone worldwide can join. From over-collateralized lending and its pioneering flash loans, to the native GHO stablecoin, the V4 Hub and Spoke architecture, and institutional-grade Horizon, Aave is the undisputed leader of the DeFi lending race. However, as a governance token, whether AAVE’s “protocol success” can translate into “token value” still hinges on governance decisions such as the fee switch and buybacks. When allocating to this kind of asset, we recommend closely monitoring Aave’s revenue and market share, the growth of GHO and Horizon, and the progress of the buyback mechanism’s resumption.
