Frequently Asked Questions

Summer Borrow is the main entry point for users to take advantage of DeFi. Through, users can generate (borrow) Dai, or other supported assets in any of the protocols.

For example, Dai has a stable price, soft pegged to the US dollar, and lives completely on the blockchain, making it borderless and available to anyone, anywhere. These and other blockchain benefits allow Dai to extend the power of traditional currency: it can be freely sent to others, used as payments for goods and services, or locked in a smart contract to earn savings.

Summer Borrow allows users to borrow Dai on Maker, or other assets in Aave and Ajna against any collateral supported like ETH, WBTC, and 20+ more. With an intuitive and world class UX that’s constantly evolving to suit users needs, the process to borrow Dai is seamless.


  • Extra liquidity: Users gain access to extra liquidity.

  • Multiple collaterals: Different collateral types, rates and collateral ratios are suitable for multiple risk profiles.

  • Flexible repayment schedules: There are no repayment schedules, no minimum payments, and no credit history requirements. Users can repay at their own pace as long as their Vault is properly collateralized

What are the differences between supported protocols for Borrow?

For Borrow, you can choose between Maker, AAVE, and Ajna. The most important differences with each protocol are:

  1. Maker & Aave both use oracles. Maker has a 1-hour delay between oracle updates. This means that a position only becomes uncollateralized with a one-hour delay, allowing you more time to unwind your position. For Aave, liquidations are instantaneous, but this allows the protocol to have a lower penalty fee for liquidation. The liquidation penalty for each asset can be seen in the liquidation price tooltip. Maker uses its own oracle network to report prices, while Aave utilizes Chainlink services. Ajna does not use internal oracles.

  2. Aave supports higher multiples and pays interest on the collateral deposited since it works with a single pool for lending and borrowing. This means that in cases where the protocol fails to deal with defaulting accounts properly and is left with bad debt, the risk is spread across all protocol users.

  3. Aave has, in general, support for different tokens both as collateral and debt, allowing you to borrow different tokens.
