title: [Direct-to-AIP] Asset Listing - USDC X Layer
author: @TokenLogic
created: 2026-08-12
Summary
This ARFC proposes to onboard native USDC as a supported asset on the Aave V3 X Layer Instance.
USDC was recently deployed natively on X Layer by Circle, alongside support for the Cross-Chain Transfer Protocol (CCTP). This proposal seeks to expand the stablecoin offering available on Aave V3 X Layer and provide users with an additional highly liquid, fiat-backed asset for supplying, borrowing, and collateral usage.
Motivation
On August 6, 2026, Circle launched native USDC and CCTP on X Layer. Native USDC on X Layer is issued by Circle, fully reserved, and redeemable 1:1 for US dollars through eligible Circle channels. CCTP also enables native USDC to be transferred between X Layer and other supported networks without relying on wrapped or third-party bridged representations.
Onboarding USDC to Aave V3 X Layer would:
- Expand the range of high-quality stablecoin assets available to Aave users on X Layer.
- Provide an additional asset for lending and borrowing alongside USDT0, USDG, and GHO.
- Increase the available stablecoin borrowing liquidity for the existing xBTC, xETH, xSOL, and WOKB E-Mode categories.
- Enable users and institutions to access native USDC liquidity supported by Circle Mint and CCTP infrastructure.
The deployment provides X Layer with direct access to one of the most established stablecoins in DeFi and creates an opportunity to deepen stablecoin liquidity across the ecosystem.

E-Mode Configuration
We propose adding USDC as a borrowable asset to the four existing stablecoin-borrowing eMode categories on X Layer, following the same configuration currently applied to USDT0.
eMode #1
| Parameter | Value | Value | Value | Value | Value |
|---|---|---|---|---|---|
| Asset | xBTC | USDT0 | USDC | USDG | GHO |
| Collateral | Yes | No | No | No | No |
| Borrowable | No | Yes | Yes | Yes | Yes |
| Max LTV | 78.00% | - | - | - | - |
| Liquidation Threshold | 81.00% | - | - | - | - |
| Liquidation Bonus | 6.00% | - | - | - | - |
eMode #2
| Parameter | Value | Value | Value | Value | Value |
|---|---|---|---|---|---|
| Asset | xETH | USDT0 | USDC | USDG | GHO |
| Collateral | Yes | No | No | No | No |
| Borrowable | No | Yes | Yes | Yes | Yes |
| Max LTV | 78.00% | - | - | - | - |
| Liquidation Threshold | 80.00% | - | - | - | - |
| Liquidation Bonus | 6.00% | - | - | - | - |
eMode #3
| Parameter | Value | Value | Value | Value | Value |
|---|---|---|---|---|---|
| Asset | xSOL | USDT0 | USDC | USDG | GHO |
| Collateral | Yes | No | No | No | No |
| Borrowable | No | Yes | Yes | Yes | Yes |
| Max LTV | 65.00% | - | - | - | - |
| Liquidation Threshold | 70.00% | - | - | - | - |
| Liquidation Bonus | 7.50% | - | - | - | - |
eMode #4
| Parameter | Value | Value | Value | Value | Value |
|---|---|---|---|---|---|
| Asset | wOKB | USDT0 | USDC | USDG | GHO |
| Collateral | Yes | No | No | No | No |
| Borrowable | No | Yes | Yes | Yes | Yes |
| Max LTV | 50.00% | - | - | - | - |
| Liquidation Threshold | 55.00% | - | - | - | - |
| Liquidation Bonus | 10.00% | - | - | - | - |
These are the four existing X Layer eMode configurations. USDT0, USDG, and GHO are currently configured as borrowable stablecoins within each category; this proposal would extend the same functionality to USDC.
Oracle
A Chainlink USDC/USD Price Feed is already available on X Layer Mainnet.
| Parameter | Value |
|---|---|
| Feed | USDC / USD |
| Network | X Layer Mainnet |
| Chainlink Oracle | 0xB8a08c178D96C315FbFB5661ABD208477391BC40 |
Chainlink identifies this feed as USDC/USD-RefPrice-DF-XLayer-001.
We propose using the Chainlink USDC/USD feed for pricing USDC, with the final oracle configuration to be confirmed by the relevant Aave Risk and Technical Service Providers.
