[Direct-to-AIP] Onboard USDe to the Aave V3 MegaETH Instance

Summary

This proposal seeks to onboard USDe to the Aave V3 MegaETH instance.

The listing of this asset would expand the range of supported stable and yield-bearing collateral available on MegaETH and strengthen the instance’s utility for users seeking to supply, borrow, and manage stablecoin-linked positions within the Aave protocol.

Motivation

Ethena’s USDe has seen meaningful adoption across DeFi and represents assets with clear user demand and strategic relevance.

Listing this asset on the Aave V3 MegaETH instance would improve market completeness and help position the deployment to capture additional stablecoin and yield-oriented activity from day one. It would also align the MegaETH instance more closely with assets already familiar to a broad segment of DeFi users.

Specifications

This proposal recommends onboarding the following asset to the Aave V3 MegaETH instance:

  • USDe

Risk service providers will provide the full risk parameter recommendations, including all relevant listing and configuration parameters required for Aave governance consideration.

Next Steps

Following community feedback, the next step is to wait for the risk analysis and parameter recommendations from the Risk Service Providers.

Once that analysis is available, an AIP will be posted with the proposed final configuration for both assets.

Summary

LlamaRisk supports the onboarding of USDe to the Aave V3 MegaETH instance. The asset is well established within the Aave ecosystem and has been successfully deployed across multiple instances, including Ethereum, Arbitrum, Base, Avalanche, and Plasma. Its risk profile is well understood, and the LayerZero OFT (Omnichain Fungible Token) bridging architecture used for cross-chain deployment introduces no additional structural risk relative to prior deployments. Initial seed liquidity for USDe of size in $6M total liquidity TVL has been deployed on MegaETH, providing an initial foundation for secondary markets.

On Aave V3 MegaETH deployment USDe will be structured as an asset offering a yield passthrough for USDe deposits, making USDe equivalent to sUSDe and not requiring to onboard sUSDe to allow for yield leverage looping. This is partially enabled by the lowered sUSDe unstaking cooldown.

1. Asset Fundamental Characteristics

1.1 Asset

USDe is a dollar-pegged synthetic stablecoin issued by Ethena Labs, backed by delta-neutral positions. Extensive analyses of USDe have been conducted in prior assessments, including:

1.2 Architecture

USDe on MegaETH is bridged through LayerZero infrastructure using the Omnichain Fungible Token (OFT) standard. On Ethereum mainnet, the OFT Adapter locks tokens in the adapter contract; on destination chains such as MegaETH, equivalent tokens are minted. When bridging back, tokens are burned on MegaETH and unlocked on Ethereum, maintaining canonical supply parity. This architecture is already present on multiple Aave deployments and introduces no incremental risk.

USDe Contract Address on MegaETH: 0x5d3a1Ff2b6BAb83b63cd9AD0787074081a52ef34

1.2.1 Bridge Configuration

The USDe OFT contract on MegaETH connects to a shared LayerZero V2 Endpoint at 0x6f475642a6e85809b1c36fa62763669b1b48dd5b. The bridge configuration is as follows:

Parameter USDe
Peered chains Ethereum
Rate limit 10,000,000 tokens / 1 hour

USDe on MegaETH is peered exclusively with Ethereum mainnet. No secondary bridge routes (e.g., to Arbitrum, Base, or other L2s) are configured. This means that in a stress scenario, all bridging activity, both inflows and outflows, must route through the Ethereum pathway.

The rate limit is set at 10M tokens per 1-hour window, providing generous throughput relative to the current on-chain supply. At scale, this would allow up to $240M in daily bridge throughput per direction. However, the single-chain peering represents a concentration point: if the LayerZero messaging channel to Ethereum were disrupted, there would be no alternative path for cross-chain transfers.

No external rateLimiter contract is designated for USDe. Rate limit modifications can only be initiated by the contract owner (the 5/10 multisig), which provides a measure of governance overhead for any parameter changes but may limit operational responsiveness in urgent scenarios.

1.3 Tokenomics

1.3.1 Token Holder Concentration

As of April 6, 2026, on-chain supply of USDe on MegaETH is 3,000,166**.**45 tokens, vast majority of that amount being deposited into the USDe/USDm DEX pool to bootstrap the initial liquidity. Once listed on Aave MegaETH, supply is expected to grow via LayerZero bridging as users deploy capital for borrowing and yield strategies, leading to natural demand.

2. Market Risk

2.1 Liquidity

Seed liquidity for USDe on MegaETH has been deployed. A USDe/USDm pool on Kumbaya is live with approximately $6M in initial liquidity. This provides a baseline for secondary market activity and liquidation routing support at the time of listing. Initial caps are set conservatively and would be scaled upward as additional liquidity develops across MegaETH DEXes as well as the aggressiveness of the borrows is observed.

2.2 Volatility

USDe has maintained a stable peg over the course of the year, with the exception of a brief depeg event in October 2025, caused by 10/10 events. The token has been trading at a slight discount of up to 20 bps for the past 3 months.

  • Maximum discount from peg: 2.33%
  • Mean discount from peg: 0.027%
  • Minimum recorded price: $0.9772


Source: LlamaRisk, April 7, 2026

2.3 Exchanges

On MegaETH, seed liquidity is available via the USDe/USDm Kumbaya pool (~$6M). Primary liquidity access remains through Ethena’s minting/redeeming mechanism on Ethereum mainnet, with cross-chain bridging via LayerZero. USDe is also listed on major centralized exchanges including Binance, Bybit, KuCoin, MEXC, and others.

2.4 Growth

2.4.1 Ethena’s Current State

Ethena’s protocol TVL stands at approximately $5.89B. The protocol has undergone a contraction from its peak (~$14.8B USDe supply), driven by a combination of lower funding rates in the crypto derivatives market and broader risk-off period of the market. However, the Liquid Leverage product, which enables leveraged sUSDe strategies on Aave, has further linked Ethena’s growth profile to leverage demand. The proposed setup on MegaETH deployment would enable a novel yield passthrough strategy for USDe, allowing for direct yield generation without needing to tap into sUSDe.


Source: LlamaRisk, April 7, 2026

2.4.2 Growth on MegaETH

As the chain is relatively new (mainnet launched February 2026) and the Aave deployment is still establishing its asset base, meaningful adoption is expected to follow the listing and potential incentive programs. The deployment of seed liquidity for USDe signals preparations for the market scaling.

3. Technological Risk

3.1 Smart Contract Risk

Ethena’s core protocol contracts (USDe, minting) have been audited by multiple firms including Zellic (July 2023) and others listed on Ethena’s audits page. The LayerZero OApp/OFT framework used for cross-chain bridging was separately audited by Zellic (September 2025). The MegaETH-specific OFT deployment uses the same audited codebase but has not received a chain-specific audit.

MegaETH’s security model delegates consensus and state settlement to Ethereum and data availability to EigenDA. The chain uses a rollup architecture with specialized node roles. As a recently launched L2, the chain’s track record is limited compared to more established rollups.

3.2 Bug Bounty Program

  • Ethena: Maximum bounty of $3M via Immunefi for critical smart contract vulnerabilities (10% of affected funds, minimum $100k).
  • LayerZero: Maximum bounty of $15M via Immunefi for critical smart contract vulnerabilities. However, OFT-related contract impacts are classified as low severity with a maximum payout of $10,000.

4. Counterparty Risk

4.1 Access Control Risk

The USDe OFT contract on MegaETH inherits OpenZeppelin’s Ownable standard and implements a 2-step ownership transfer process via OFTOwnable2Step. The owner has the following administrative capabilities:

  • Transfer or renounce ownership
  • Set the rateLimiter contract address
  • Modify rate limits for cross-chain transfers (owner or rate limiter)
  • Register trusted peers via setPeer()

A malicious or compromised rate limiter could interrupt cross-chain transfers, potentially preventing users from bridging assets back to the canonical chain. As of this analysis, no external rateLimiter contract is set for USDe on MegaETH, rate limit modifications require a transaction from the owner multisig.

4.2 Contract Modification

The USDe OFT contract on MegaETH has no proxy-based code upgradeability. The modifiable surface is limited to owner-controlled administrative configuration (rate limits, ownership). No timelock is present in the contract.

4.3 Multisig Configuration

USDe on MegaETH is owned by a Safe multisig at 0x6e61463eC8ef3c585bB534473528f5fa68C9A709 with a setup of 5/10 threshold.

Parameter Recommendations

The following risk parameters are recommended for USDe on the Aave V3 MegaETH instance. Initial supply and borrow caps are set conservatively relative to the available onchain liquidity (~$6M in the USDe/USDm Kumbaya pool) and would be scaled upward as the secondary market develops as well as the aggressiveness of the positions is observed on Aave MegaETH market.

To direct usage toward the intended stablecoin borrowing use case, USDe is constrained to function as collateral exclusively within a dedicated USDe-Stablecoins E-Mode category. Within this E-Mode, only USDm and USDT0 are borrowable against USDe. This design would move USDe collateral into stablecoin-linked strategies, aligning with the available liquidity profile and limiting exposure to volatile strategies on the collateral side.

Overview

Chaos Labs supports the listing of USDe on the Aave V3 MegaETH instance. The asset has a proven track record on Ethereum, demonstrating strong user demand. Below, we present MegaETH-relevant analysis of USDe along with initial risk parameter recommendations.

Bridging

USDe bridges between Ethereum and MegaETH via LayerZero using two contracts: an adapter on Ethereum that escrows the canonical tokens and an OFT on MegaETH that mints and burns. For Ethereum to MegaETH, users approve the adapter and call send; the adapter locks the tokens, emits a LayerZero message, and the MegaETH OFT mints the same amount to the recipient’s address. By default, there are no bridge haircuts, as the amount sent equals the amount received. USDe cannot be minted natively on MegaETH, since its contract mints only when a LayerZero message confirms tokens have been locked on Ethereum, making it a purely bridged representation. The USDe OFT on MegaETH is peered exclusively with Ethereum, meaning all bridging activity must route through this single pathway. Rate limits are set at 10M tokens per 1-hour window and the contract is owned by a 5/10 Safe multisig and implements a 2-step ownership transfer process via OFTOwnable2Step, with no proxy-based upgradeability.

Market & Liquidity

The USDe OFT contract on MegaETH was deployed on January 30, 2026, with small test mints through February and early April. The main liquidity deployment occurred on April 7, when approximately 3M USDe was bridged and deposited into a UniswapV3 USDe/USDm pool. Total on-chain supply currently stands at approximately 3.34M, with 99.99% concentrated in this single pool at a TVL of approximately $6M. The pool has maintained a tight peg, with a maximum observed depeg of just 0.033% across a total of 51 swap events. Trading volume remains minimal, with the majority of activity driven by a single LP rebalancing event on April 10. Only 22 unique addresses have held USDe on MegaETH to date. Given MegaETH’s recent mainnet launch and the concentration of liquidity in a single venue, on-chain liquidity is modest compared to more mature deployments. However, the LayerZero OFT standard ensures that bridging from Ethereum provides a reliable path for supply growth as demand materializes. Primary liquidation backstops remain accessible through Ethena’s minting and redemption mechanism on Ethereum mainnet and across major centralized exchanges.

Risk Parameters

Given the limited on-chain liquidity history on MegaETH and the concentration of DEX liquidity in a single pool, we recommend disabling USDe as collateral outside of E-Mode. We therefore recommend establishing a dedicated E-Mode and setting LTV at 90%, LT at 93%, and LB at 2%, consistent with USDe E-Mode configurations on other instances. This approach concentrates collateral usage in stablecoin-linked strategies aligned with the available liquidity profile on MegaETH, while avoiding exposure to volatile borrowing positions where the limited DEX depth could impair liquidation execution.

Supply Cap and Borrow Cap

Given the scale and growth of USDe’s on-chain liquidity, along with the seamless cross-chain bridging enabled by LayerZero OFT, we believe a relatively high supply cap is justified. We therefore recommend setting the initial supply cap at 50 million while aligning the borrow cap to optimal utilization at 40 million tokens.

Interest Rate

We recommend aligning USDe’s interest rate parameters with those of other stablecoins on MegaETH. At the same time, we suggest setting a lower Uoptimal at 85% to account for USDe’s recent launch on MegaETH and its relatively limited supply.

Pricing

We recommend using the USDT/USD Chainlink oracle to price USDe, consistent with the pricing approach used across all active Aave instances.

Greetings Aave community,

The MegaETH proposal, proposal 471, that was expected to execute yesterday was delayed on the voting chain, Avalanche, during the switch from the Chainlink API-based execution flow to CRE. This delay prevented the Aave Robot from automatically executing the proposal’s payload.

BGD handled the Chainlink CRE transition and assisted in resolving the voting delay. Today, after Proposal 473 passed, BGD manually executed the payload, upgrading the MegaETH deployment from Aave V3.6 to Aave V3.7.

The protocol is functioning as intended. Proposal 471 was built against the previous V3.6 deployment, and is no longer valid for execution in its current form. This proposal must expire and be re-proposed to the current V3.7 deployment.
