Terms & Conditions

Returns the standard deviation of Interest Rates for Aave Reserves over time:

Standard deviation of interest rates

Returns time averaged Interest Rates for Aave Reserves:

Average interest rates

Returns key metrics for Aave Reserves:
- Total Supplied (TVL) in USD
- Total Borrowed in USD
- Utilization Ratio

See below for more info:

Reserve overview

Returns the latest APY and APR rates for a specified token on Aave, for both
deposits and loans.

**Annual percentage yield (APY)** is the yearly return/cost after continuous
compounding of the per-second rate stored on-chain. This value is the same value as
seen the on [app.aave.com](
https://app.aave.com/)
but more up-to-date as it is taken directly from the
blockchain every time this endpoint is called.

**Annual percentage rate (APR)** is the yearly simple interest rate (no
compounding).

For APY/APR on loans Aave offers both stable and fixed rates on certain tokens.

Interest rates

This endpoint retrieves the current price of a specified token in USD as
determined by the Aave protocol.

It utilizes the Aave V3 Oracle to fetch the token price, ensuring accurate and up-
to-date information. The request requires the token identifier and the blockchain
network (chain) on which the token resides. The response provides the token price in
a standardized format, converted from Wei to the base currency decimals defined by
Aave.

Token prices

This endpoint retrieves the change in the reserve liquidity index between two
provided blocks.

This is then converted to a percentage change. The liquidity index represents the
change in debt and interest accrual over each block. Aave does not store individual
user balances directly. Instead, it keeps a scaled balance and uses the liquidity
index to compute real balances dynamically. If a user was to have deposited tokens
at the start block, a positive liquidity index change will represent accrued
interest and a profit. If tokens were borrowed at the start block, this debt will
increase, compound on itself and represent large debt. The reverse in both cases is
true if the liquidity index is negative.

Liquidity index

This endpoint retrieves a comprehensive summary of a user's position on the AAVE
platform.

It provides key financial metrics including the total collateral deposited, total
debt accrued, available borrowing capacity, liquidation threshold, maximum loan-to-
value ratio, and the health factor of the user's account. These metrics are
calculated by aggregating data across all open positions held by the user, offering
a holistic view of their financial standing within the AAVE ecosystem.

Positions - total

This endpoint retrieves the user's position for a specific token on the AAVE
platform.

It provides key financial metrics including the current aToken balance, current
stable debt, current variable debt, principal stable debt, principal variable debt,
stable borrow rate, stable borrow rate for new loans, variable borrow rate, and
liquidity rate. These metrics are calculated by aggregating data across all open
positions held by the user for the specified token, offering a detailed view of
their financial standing within the AAVE ecosystem.

Positions - per token

This endpoint retrieves historical transactions for a user on the AAVE platform.

It returns a list of transactions including deposits, withdrawals, borrows, and
repayments. Each transaction includes details such as the token, amount, timestamp,
and transaction type. This provides a comprehensive view of the user's historical
activity within the AAVE protocol.

Historical transactions

By supplying assets, users can earn interest on their deposits.

The supplied collateral can be used as a basis for borrowing other assets, allowing
users to leverage their positions. In combination with a trading protocol, this can
create leverage.

Overall, this endpoint is a critical component for users looking to maximize their
asset utility within the AAVEv3 ecosystem, providing both earning potential and
borrowing flexibility.

Supply/Lend

You will pay interest for your borrows.

Price changes in the assets may lead to some or all of your collateral being
liquidated, if the borrow position becomes unhealthy.

Borrow

This endpoint allows users to repay a portion or the entirety of their borrowed
tokens on the Aave platform.

By repaying borrowed amounts, users can improve their health factor, which is a
measure of the safety of their loan position. A higher health factor reduces the
risk of liquidation, ensuring a more secure borrowing experience. The endpoint
requires specifying the chain and the details of the repayment transaction,
including the amount and the asset to be repaid.

Repay loans

This endpoint facilitates the withdrawal of collateral from the Aave protocol.

Users can withdraw a portion or all of their collateral, which may increase the risk
of liquidation if there are outstanding borrows. The withdrawal process also
includes the collection of any interest earned on the collateral. It is important
for users to carefully consider their outstanding debts and the potential impact on
their liquidation threshold before proceeding with a withdrawal. This endpoint is
designed to provide a seamless and efficient way to manage your collateral within
the Aave ecosystem.

Unstake

Retrieve the total number of Liquidity Provider (LP) positions associated with a
specific sender.

This endpoint allows users to query and obtain detailed information about their LP
positions, including the number of active positions they hold. The response model,
AerodromeLPPositionsInfo, provides a structured representation of the LP positions
data, ensuring clarity and ease of use. This functionality is essential for users
managing their liquidity provision activities, enabling them to make informed
decisions based on their current positions.

List LP positions

This endpoint retrieves the current price of a pool, indicating how many token0
you can purchase for 1 token1.

Note that this is an instantaneous price and may change during any trade. For a more
accurate representation of the trade ratios between the two assets, consider using
the quote endpoint.

Pool price

This endpoint allows users to trade a specific amount of one token into another
token using the Aerodrome Slipstream protocol.

The transaction is executed by specifying the exact amount of the input token to be
sold, and the system calculates the amount of the output token that will be
received. The operation ensures that the trade is conducted within the constraints
of the current market conditions, taking into account the liquidity and price
impact. This endpoint is suitable for users who want to sell a precise quantity of a
token and are willing to accept the resulting amount of the other token.

Swap - from specified amount

This endpoint facilitates the trading of tokens by allowing users to specify the
exact amount of the output token they wish to receive.

Utilizing the Aerodrome Slipstream protocol, the system calculates the necessary
amount of the input token required to achieve the desired output. This operation is
particularly useful for users who have a specific target amount of the output token
in mind and are willing to provide the corresponding input token amount. The
transaction is executed with consideration of current market conditions, including
liquidity and price impact, ensuring that the trade is completed efficiently and
effectively.

Swap - into specified amount

Initiate a new Liquidity Provider (LP) position by minting tokens.

This endpoint allows users to open a new LP position, enabling them to participate
in liquidity provision. The minting process involves creating a new position with
specified parameters, such as token amounts and pool details. The response will
confirm the successful creation of the LP position, providing users with the
necessary information to manage their newly minted position. This functionality is
crucial for users looking to expand their liquidity provision activities, offering
them the opportunity to engage in decentralized finance (DeFi) markets effectively.

Open a new LP position

Increase the liquidity of an existing Liquidity Provider (LP) position.

This endpoint allows users to add more tokens to their current LP position,
enhancing their participation in liquidity provision. By increasing liquidity, users
can potentially earn more rewards and improve their position in the pool. The
process involves specifying additional token amounts and updating the pool details.
The response will confirm the successful increase of the LP position, providing
users with updated information about their enhanced position. This functionality is
vital for users aiming to optimize their liquidity provision strategy, enabling them
to adapt to market conditions and maximize their returns in decentralized finance
(DeFi) markets.

Increase an LP position

Withdraw an existing Liquidity Provider (LP) position.

This endpoint allows users to remove their tokens from an LP position, effectively
closing their participation in the liquidity pool. The withdrawal process involves
specifying the LP position to be closed, and the response will confirm the
successful removal of liquidity, providing users with details about the withdrawn
tokens and any remaining balances. This functionality is essential for users who
wish to exit their liquidity provision activities, enabling them to reclaim their
assets and potentially reallocate them to other investment opportunities. The
endpoint ensures a smooth and secure withdrawal process, facilitating users'
strategic management of their decentralized finance (DeFi) portfolios.
