Aave faces challenges in achieving scalability, particularly as transaction volumes increase and the Ethereum network becomes congested. High gas fees and slow transaction times on the Ethereum mainnet can make it costly for users to interact with the protocol. However, Aave has been integrating with Layer 2 solutions like Optimism and Arbitrum to overcome these issues. By leveraging these solutions, Aave can offer faster, cheaper transactions and scale its protocol to accommodate more users and liquidity providers.
