[ARFC] Deployment of Aave on Linea

[ARFC] Deployment of Aave on Linea

Author: ACI

Date: 2024-11-19

Simple Summary

The current ARFC proposes deploying Aave V3 on Linea to expand Aave’s reach and use cases on zk-Rollups. By integrating with Linea, Aave can offer users more efficient transactions while maintaining the security of the Ethereum mainnet. This ARFC seeks governance approval to deploy an Aave V3 instance on Linea.

Motivation

Linea is a Layer 2 built on Ethereum, powered by a zkEVM tech stack developed by Consensys. Linea is the result of more than five years of cryptographic research and 20 months of dedicated R&D. The Consensys team has a strong track record in the zk space, including contributions like the GNARK library and active involvement in Ethereum’s Merge. Linea is well-positioned within the developer ecosystem through relationships with MetaMask, SMG, and Infura.

By deploying on Linea, Aave can leverage high throughput and fast finality, enabling efficient transaction processing and reduced gas fees. Additionally, Linea’s integration with Consensys products allows seamless distribution to users, potentially reaching MetaMask’s 30 million active users. This presents an opportunity to make DeFi more accessible and expand Aave’s user base.

Linea’s TVL currently sits at ~$780M. Further Linea market data can be found here.

Benefits of deploying to Linea

  1. Scalability and Performance: Linea enables high throughput and fast finality for zk networks, allowing Aave to scale effectively alongside Linea as its technology advances.
  2. Accessibility and Distribution: Linea is integrated with Consensys products like MetaMask, and Infura, facilitating seamless distribution to users and making DeFi more accessible to MetaMask’s 30 million active users.
  3. GHO Integration: Upon successful deployment and bootstrapping of Aave on Linea, the Consensys team is motivated to enable GHO, Aave’s stablecoin, to be spendable on the MetaMask Debit Card, which is exclusively available on Linea.
  4. Growth Opportunities: With exciting growth catalysts for Linea in the upcoming H1, establishing Aave as the premier lending market on Linea will ensure long-term sustainability and growth for the Aave protocol.

Specification

Proof of Liquidity (POL) and Deposit Commitments

  1. Aave DAO commits to redistribute to Aave users via liquidity mining, GHO secondary liquidity incentives, safety module deployments, or merit programs any airdrop provided by the Linea ecosystem.
  2. ACI, on behalf of the Aave DAO, will coordinate any liquidity mining campaign on a Linea Aave V3 deployment.

Risk Parameters

Risk parameters will be provided by service providers and this section will be updated in due course.

I think Linea is a pretty big name and brands like Metamask are also well known. If the market grows well and GHO could be included into the Metamask card as a payment option this could lead to good growth for GHO and the name would be spread across different groups of people.
Which kind of assets are considered to be listed on that market?

This would be great
Linea/Consensus are looking to ramp up aggressively

Since they’re trying to build in & incentivize usage of Linea within the Metamask wallet (the most popular wallet), perhaps with a protocol as credible as AAVE on Linea, they would consider adding Lend / Withdraw / Borrow / Repay buttons into Metamask while on Linea chain (as they have done with swaps)

Linea is 7th biggest EVM chain, large market and growing

Summary

LlamaRisk supports deployment to Linea. This recommendation is based on a developmental Chain Qualification Framework (CQF) that we are beginning to share with ecosystem partners for feedback. While not a substitute for technical audit, our evaluation indicates the risks are high but acceptable. Significant trust assumptions in Consensys’ good faith and competence remain, but we view the network as sufficiently developed for an Aave deployment. Current lending protocol metrics on Linea indicate strong potential for Aave to capture significant market share, given its established brand equity and resources. LlamaRisk will monitor Linea’s progress, coordinate with other Service Providers to propose launch parameters, and inform Aave DAO of any changes that could impact operations. We maintain an ongoing line of communication with the Linea team and will continue clarifying various issues related to the identified governance, technical, architectural, and access control risks.

Network Fundamentals

Linea is a zkRollup L2 for Ethereum launched in August 2023. As an EVM-equivalent platform, smart contracts can be deployed without modification. The network uses ZK-proofs to reduce data storage on L1, processing transactions in 2-3 seconds on L2 with block times averaging that speed, while final L1 settlement takes 8-48 hours. Since launch, Linea has produced 12.3M blocks and confirmed 223M transactions, maintaining an average of 1.8 TPS with a gas price of 0.6 gwei (paid in ETH). The platform remains partially centralized, with a single sequencer retaining all ETH from L1 postings and no financial incentives for node operators.

Market Risks

Established infrastructure essential for Aave deployment is present on Linea, including DEXs with verifiable volume, Chainlink price feeds, and a range of reputable assets. Active liquidation activity across lending platforms on Linea demonstrates satisfactory chain health. The chain’s primary economic activity centers on leveraged Ethereum staking through leading protocols: Zerolend ($183M TVL, Aave V3 fork), Kelp ($130M, LST), and Renzo ($128M, LST). Other notable lending protocols include Mendi (Compound V2 fork deployed by the Sonne finance team) and LayerBank, which initially launched on Linea before expanding cross-chain.

Several key metrics highlight current market limitations. Chain TVL has declined from $850M to $540M since July, though future ecosystem incentives could reverse this trend, as demonstrated by the previous Surge points program, which doubled network TVL. Decentralized exchange activity remains modest, with approximately $25M daily volume (compared to ±$50M on Mantle). Limited market depth is particularly evident - only USDC.e/WETH trades on Odos maintain less than 7.5% price impact at $1M size.

The high concentration of cross-network assets presents additional risk factors. Canonically bridged tokens comprise over 80% of chain TVL, with stablecoins at ±$43M (USDC.e dominating at 73%). This dependency on cross-network assets may create liquidation routing risks depending on native network liquidity.

Technical Risks

Two significant design choices in Linea’s network architecture warrant attention. Currently, only one node implementation enables interfacing with the network. While functional, this single implementation creates a potential point of system interruption that could affect block production if implementation-specific issues occur. This setup contrasts with Ethereum’s ecosystem, which utilizes 8 node implementations for enhanced resilience. A second key consideration is that contract upgrades can be executed without timelocks, meaning users have no mandatory waiting period to exit if they disagree with proposed updates.

Despite these risks, the network has established strong foundational elements. It features comprehensive data infrastructure and developer tooling, including an Etherscan-equivalent block explorer at lineascan.build. A native Safe deployment enhances transparency and reduces development friction. The network’s EVM equivalence ensures broad compatibility with Ethereum smart contracts (with documented exceptions), and Consensys is progressing toward complete EVM equivalence.

On the security front, Linea’s framework includes extensive auditing, a $100K bug bounty, real-time transaction monitoring via Hypernative, and economic risk analysis through IntoTheBlock. Additionally, partnerships with leading infrastructure providers like LayerZero, Axelar, CCIP, and various data providers strengthen the ecosystem’s resilience.

Counterparty Risk

Currently, network control remains concentrated within Consensys through a hierarchical multisig structure: a 4/8 Safe controls core functions, while a likely Consensys-controlled 3/6 Safe maintains oversight. Unlike Optimism’s sequencer, this structure could allow Consensys to restrict fund withdrawals.

Consensys is implementing a progressive decentralization strategy, currently governed by Consensys Software Inc.'s Terms of Use. The Phase 3 roadmap introduces the independent Linea Association, with Nicolas Liochon as the only confirmed appointee. The Association’s establishment coincides with the LINEA token launch in Q1 2025. While Consensys faces SEC scrutiny over MetaMask, the planned Linea Association may provide regulatory separation. The upcoming token generation event presents market uncertainties, though strategic partnerships and the Ecosystem Investment Alliance provide stability.
