What is the Atlendis protocol?

Atlendis is a capital-efficient DeFi protocol enabling uncollateralized crypto lending to institutional borrowers. Atlendis enables lenders to deposit digital assets in a single pool per asset and per borrower, and to earn liquidity rewards while funds are unused and additional rewards as funds are lent out.

Has the Atlendis protocol been audited?

Atlendis Labs has mandated Runtime Verification to audit the protocol’s smart contracts. The audit report is available on the following page.

Who can use the Atlendis protocol?

Anyone can use the protocol to lend assets. Only whitelisted institutional borrowers can take out a loan, for more information please refer to the borrower FAQ.

On which network/blockchain is the Atlendis protocol operating?

The Atlendis protocol is operating on Ethereum mainnet and Polygon.


What is a position?

Each liquidity provider’s deposit on the Atlendis protocol is characterized by a position. The positions are represented by an NFT with original artwork. A position is characterized by:
  • Borrower pool
  • Chosen lending rate
  • Quantity of bonds held if the pool is actively used by the borrower and the funds in the position have been borrowed
  • Amount of unused capital placed on a third-party liquidity protocol (i.e. Aave).

What type of assets can a lender deposit into a borrower pool?

All pools on the Atlendis protocol are single-asset pools. The type of assets that lenders can deposit on the Atlendis protocol depends on the assets required by the borrower at the pool’s creation time. Lenders can filter the pools by asset type in the “Atlendis” section of the dApp.

Where can I find information on the borrower?

Information about the borrower is available on the borrower's pool page.

Why are my funds currently not actively loaned out?

Either the borrower is not currently borrowing from their pool, or other liquidity providers in the pool have set lower lending rates and therefore, their funds have been lent on a priority basis.

How can lenders know if their funds are going to be borrowed when choosing their lending rate?

Looking at the maximum borrowable amount and the volume weighted average lending rate should give lenders an indication of how likely their funds are to be borrowed.

Where can one find a summary of their position?

This can be found on the position page of the dApp.

How should a lender choose their lending rate?

The lender's lending rate should depend on the lender’s own risk assessment of the borrower’s default risk. Note that since unused capital benefits from Aave’s APY, it is highly recommended to choose a lending rate that is higher than Aave’s rate to ensure that the lender actually benefits from having their capital borrowed.

Is there a limit for lending rate?

Yes, the chosen lending rate must remain within a range set at the pool’s creation time.

Why is the maximum lending rate fixed?

The maximum rate is fixed with the borrower at the pool’s creation time. It is the highest rate at which the borrower might be willing to borrow. Having a maximum rate removes the risk of a borrower never using their pool, which would be detrimental for lenders.

Why is the minimum lending rate fixed?

Unused capital is placed on Aave, benefitting from Aave’s APY. Having a minimum rate that is higher than Aave’s yield eliminates the possibility for lenders with no capital actively loaned out to benefit from a higher rate than lenders with actively loaned out capital.

What is the maturity of a loan?

The maturity of a loan is a parameter that is fixed at the opening of the pool and visible on the pool’s description card.

Position Management

Are lenders’ funds withdrawable at any time?

Funds that are not actively loaned out are withdrawable at any time. Funds that have been loaned out cannot be withdrawn, but lenders’ positions can then be sold as an NFT (as described in Position) on an NFT marketplace.

Can liquidity providers change their lending rate?

Liquidity providers can change their position's lending rates as long as their funds are not actively loaned out.

Are there any fees to deposit and/or withdraw on the Atlendis protocol?

Yes, gas fees.

What is the cool down period?

The cool down period is the minimum period of time that the borrower must respect between two borrows.

How does the cool down period help me to withdraw?

If part of the funds are actively loaned out, the funds cannot be withdrawn until repayment. It is optimal to withdraw during the cool down period to prevent the funds from being borrowed again.

Atlendis Rewards

Where are funds deposited when they are not actively loaned out?

Funds that are not actively loaned out are deposited on Aave, earning Aave’s APY on top of liquidity rewards paid by borrowers as an interest on unused capital.

When do lenders start accumulating liquidity rewards?

Lenders start accumulating liquidity rewards as soon as their funds are exposed to being borrowed. That is on day one if the pool is not actively used, and at repayment time if the pool is fully used at deposit time.

Why was Aave selected to deposit unused capital?

Aave was selected as it constitutes a highly trusted third-party yield provider.

What interest do lenders earn on the Atlendis protocol?

  • Aave’s yield
  • Liquidity rewards – called liquidity fees for borrowers – are fees paid out by borrowers to lenders as an interest on unused fees, similar to commitment fees in traditional finance
  • The lender's chosen lending rate when actively lending to borrowers
  • Late repayment fees in the exceptional case the borrower enters a recovery period.

What is the minimum APY on the Atlendis protocol?

The minimum APY earned on the Atlendis protocol is Aave’s yield, plus potential liquidity rewards paid by the borrower.

Are the Atlendis protocol’s interests compounded?

Yes, interest earned on the Atlendis protocol is calculated based on both the initial deposit amount and the accumulated interest.

Who bears the loss in case of a borrower default?

In Atlendis V1, liquidity providers of a specific pool will bear the loss of funds in case of default of the borrower of that pool.
