Risk Disclosures

Smart Contract Risk: Aave V3 contracts deployed on Arbitrum inherit mainnet security with L2-specific considerations. Layer 2 Risk: Arbitrum relies on a centralized sequencer. Sequencer downtime could prevent transactions. Bridge Risk: Assets bridged to Arbitrum depend on bridge contract security. Native USDC avoids this for that asset. Withdrawal Delay: Official withdrawals from Arbitrum require a 7-day challenge period (third-party fast bridges offer instant exits with fees). Lower Liquidity: Arbitrum markets have less liquidity than mainnet, potentially causing larger rate volatility. Oracle Risk: Chainlink operates on Arbitrum, but L2 oracle infrastructure has less history. Utilization Risk: Smaller markets may see higher utilization volatility during market stress.
