[ARFC] Endorse the Asset Classification Framework (AAcA)

Title: [ARFC] Endorse the Asset Classification Framework (AAcA)

Author: LlamaRisk

Date: 2025-09-11

Summary

Following a community discussion, a formalization proposal by @bgdlabs, and an ARFC that passed the snapshot vote, we proposed this document to establish the Aave Asset Class Allowlist (AAcA). This framework is intended to be a collaborative tool maintained by Aave’s Service Providers to streamline and standardize the asset onboarding process. We’re opening this draft for the DAO’s feedback, as we have already started circulating it amongst SPs.

Motivation

The core principle of the AAcA is to group assets into logical categories based on their shared characteristics and collective risk profiles. This structured approach provides several key benefits:

• Clarity and Consistency: It creates a shared language for all stakeholders, from community members to risk service providers.

• Systematic Risk Assessment: By grouping similar assets, risks can be evaluated more systematically, allowing consistent risk parameters across a class.

• Deliberate Governance: It forces the DAO to make a conscious and deliberate decision before onboarding a new asset class, ensuring strategic alignment and risk awareness.

The framework is organized into six primary groups: Stablecoins, Wrapped Assets, Staking & Restaking Derivatives, Protocol Tokens, Tokenized Financial Instruments, and Uncategorized Assets. Each class within these groups is defined with a clear description, its current approval status, and examples of assets that fit the category.

• Approved classes are those that have been formalized based on currently or previously onboarded assets. Approved assets are still subject to analysis to determine if they are individually eligible for onboarding.

• Not Approved classes are those that have already been reviewed and have been explicitly not approved due to factors such as technical considerations and/or legal implications, among others.

• Not Analyzed classes are new categories introduced by recently proposed assets, suggested for future consideration, but not yet formally part of the Aave allowlist. These require assessment, community discussion and formal approval (via ARFC) before onboarding an asset of that class.

Specification

Aave Asset Class Framework

1. Stablecoins

This group includes all assets designed to maintain a stable value relative to a fiat currency, subdivided by their stabilization mechanism and yield properties.

Class Name	Description	Status	Example Assets

CDP Stablecoin	Fiat-pegged assets backed by a surplus of crypto assets, managed via a collateralized debt position (CDP) mechanism.	Approved	crvUSD, DAI, GHO, lisUSD, LUSD, USDS
Actively Managed Stablecoins
Actively Managed Stablecoin	Assets whose peg relative to fiat or its underlying is maintained through different strategies (e.g., delta-neutral positions) or vault mechanisms.	Approved	USDe, USR, scBTC, scETH, scUSD
Algorithmic Stablecoins
Algorithmic Stablecoin	Assets whose peg is maintained through algorithmic mechanisms.	Approved

Concentrated Yield-Bearing Stablecoin	Stablecoins that generate yield for holders from their underlying reserve assets being deployed to narrowly defined strategies.	Approved	sUSDe, sDAI, sUSDS

2. Wrapped Assets

This group includes tokens representing another underlying asset on a 1:1 basis, differentiated by their utility.

Class Name	Description	Status	Example Assets
Native Wrappers	ERC-20 assets that represent a wrapped version of a network or protocol token, for purposes such as non-rebasing or interim receipts.	Approved	WAVAX, WBNB, WETH, WPOL, Ws, WXDAI, eUSDe, tUSDe
Bridging Wrappers	ERC-20 assets that represent tokens bridged from a secondary chain, differentiated by their custom bridge infrastructure and non-standardized mechanisms.	Approved	BTC.b, BTCB, cbBTC, SolvBTC, tBTC, WBTC

3. Staking & Restaking Derivatives

This group includes all liquid tokens derived from Proof-of-Stake (PoS) staking or restaking activities.

Class Name	Description	Status	Example Assets
LST (Liquid Staking Token)	Liquid receipt tokens representing staked assets in a Proof-of-Stake (PoS) system.	Approved	cbETH, ETHX, LsETH, MaticX, osETH, rETH, sAVAX, weETH, wstETH, LBTC, stS, wstLINK
LRT (Liquid Restaking Token)	Liquid receipt tokens representing assets deposited into a restaking protocol like EigenLayer.	Approved	eBTC, ezETH, pufETH, rsETH, rstETH, wrsETH, xSolvBTC
Leveraged LST	Liquid staking tokens with leveraged yield optimization.	Approved	tETH, wOS

4. Protocol Tokens

This group includes tokens integral to a protocol’s function, governance, or utility.

Class Name	Description	Status	Example Assets
Governance	Tokens whose primary utility is directing a protocol’s governance through voting.	Approved	1INCH, AAVE, ARB, BAL, CRV, ENS, KNC, LDO, MKR, OP, SCR, STG, UNI
Protocol Utility Token	Assets that facilitate key functions within a protocol, such as staking, collateral, or operator rewards.	Approved	CELO, FXS, GNO, LINK, Metis, RPL, SNX, ZK

5. Tokenized Financial Instruments

This group includes tokenized derivatives and representations of traditional financial assets, including Real-World Assets (RWAs).

Class Name	Description	Status	Example Assets
Tokenized Derivatives
Principal Token (PT)	Non-yield-bearing tokens representing the principal component of a deposited asset from a yield-splitting protocol.	Approved	PT-eUSDE-29MAY2025
Tokenized Real-World Assets (RWAs)
Tokenized Commodity	Assets that are collateralized by physical commodities.	Approved	XAUt
Tokenized Securities	A tokenized representation of traditional securities such as Exchange-Traded Funds.	Not Approved	bCSPX

6. Uncategorized Assets

This group is for unique asset types that do not fit into the other categories.

Class Name	Description	Status	Example Assets
#### Uncategorized	e.g. Memecoin; these are tokens based on internet memes that typically lack fundamental utility and derive value primarily from social consensus.	Not Approved or Not Analyzed
