Governance New Asset

Summary

This proposal seeks to list Coinbase Wrapped XRP (cbXRP) on the Base network instance of Aave as a borrowable and collateral asset. cbXRP is a wrapped version of XRP, bridged and custodied by Coinbase, with on-chain deployment on the Base L2 network. Adding cbXRP to Aave would allow users to access XRP market exposure within the Base ecosystem, enabling lending, borrowing, and leveraged trading strategies without leaving the network.

Motivation

Coinbase is further integrating with its ETH L2 meaning volume could expand greatly if CEX traffic is more able to access DEX liquidity on Base, hence cbXRP could become an even bigger asset.

1. Asset Overview & Market Relevance

  • Token: Coinbase Wrapped XRP (cbXRP)
  • Contract Address (Base): 0xcbc5b58f7C08fa0e8f108bF5d915fEb8C33a4af
  • Current Price: ~$3.18
  • Market Cap: ~$37.22M
  • Circulating Supply: 11.68M cbXRP
  • Primary Markets: PancakeSwap v3 (Base), Aerodrome Slipstream (Base)
  • 24h Trading Volume: ~$424k
  • Liquidity Depth: ~$379k+ combined across top Base DEX pairs

cbXRP provides direct XRP price exposure in the Base network environment, with liquidity anchored to Coinbase’s custody model. This makes it a secure and reputable wrapped asset with clear backing and redemption mechanics.

2. Strategic Alignment with Aave Base Markets

  • Expands Aave’s Base asset offering beyond ETH, stablecoins, and blue-chip DeFi tokens into high-demand altcoins.
  • Captures XRP’s global retail and institutional interest, potentially onboarding new users from the XRP ecosystem into Base and Aave.
  • Strengthens Base network TVL by adding a non-stable, non-ETH large-cap asset with active on-chain liquidity and trading volume.

3. Risk Considerations & Mitigation

  • Counterparty risk: cbXRP is backed 1:1 with XRP held by Coinbase, which is a regulated, highly capitalized custodian.
  • Liquidity risk: While Base liquidity is smaller than mainnet, combined DEX depth exceeds $375k with sustained trading volume above $400k daily.
  • Volatility risk: XRP historically exhibits moderate volatility compared to small-cap altcoins, and cbXRP is expected to track XRP spot prices tightly.

4. Expected Impact

  • Increased borrowing and lending demand from users seeking XRP exposure or using cbXRP as collateral.
  • Opportunities for delta-neutral and yield farming strategies when paired with Base-native stablecoins.
  • Strengthened cross-asset liquidity flows between cbXRP and existing Aave Base markets.

Specification

Given cbXRP’s relatively modest Base TVL and liquidity depth, this proposal suggests using conservative risk parameters to limit systemic exposure while allowing gradual growth.

Initial Risk Parameters (Conservative)

  • Isolation Mode: Disabled
  • Borrowable: Yes
  • Collateral Enabled: Yes
  • Loan-to-Value (LTV): 60%
  • Liquidation Threshold (LT): 69%
  • Liquidation Bonus: 9%
  • Reserve Factor: 30%
  • Borrow Cap: 200,000 cbXRP (~$636k at current prices)
  • Supply Cap: 400,000 cbXRP (~$1.27M at current prices)
