### Summary

This proposal aims to onboard eBTC to the Aave v3 Base instance and establish a liquid E-Mode configuration with CbBTC. The objective is to enhance capital efficiency for users leveraging eBTC/CbBTC pairs, facilitating more effective borrowing strategies and optimizing liquidity utilization on the Base network.

Proposal will be a Direct to AIP after successful implementation of [[ARFC] Enable eBTC/WBTC liquid E-Mode on Aave v3 Core Instance](https://governance.aave.com/t/arfc-enable-ebtc-wbtc-liquid-e-mode-on-aave-v3-core-instance/20141?utm_source=chatgpt.com)

### Motivation

By implementing this proposal, we aim to optimize the use of eBTC/CbBTC within the Aave ecosystem on Base, attracting more liquidity and enhancing user experience.

- **High Utilization:** BTC-correlated pairs have demonstrated significant usage as collateral for borrowing stablecoins on other platforms.
- **Capital Efficiency:** Enabling liquid E-Mode for eBTC/CbBTC will allow borrowers to substantially improve their capital efficiency when using these assets as collateral.
- **Controlled Growth:** Liquid E-Mode provides a mechanism for more precise control over the growth and borrow demand in relation to the overall stablecoin liquidity within Aave v3 on the Base instance.

### Specification

**Network:** Base

**eBTC Market Configuration:**

Risk Parameters will be provided by Risk Service Providers and ARFC will be updated accordingly.

### Next Steps

LlamaRisk does not recommend onboarding eBTC on Base. The network is currently [host to 4 eBTC,](https://basescan.org/token/0x657e8C867D8B37dCC18fA4Caead9C45EB088C642) which is going to increase significantly in the next two weeks. LlamaRisk is excited to revisit this in the near future.
