Repay With Collateral

The repay with collateral feature allows borrowers to repay their borrowed assets using supplied liquidity within the protocol.
This feature is enabled via ParaSwapRepayAdapter. The user must first approve the contract to pull ATokens to successfully repay with collateral.

Supported Markets

Feature available on following mainnet markets:
This feature does not support repayment of a borrow transaction with the same type of asset (e.g., repaying borrowed USDC with USDC collateral). For repayments with same type of collateral asset see [Repay With ATokens feature](about:blank#repay-with-atokens).

Collateral Swap

The collateral swap feature allows the user to swap supplied liquidity in one asset type to another asset type without a separate withdrawal and supply transaction (e.g., swapping aUSDC to aDAI in a single transaction).
The collateral swap feature is enabled via the ParaSwapLiquiditySwapAdapter. The user must approve the contract to pull ATokens in order to successfully swap liquidity.

Supported Markets

The collateral swap feature is available on following mainnet markets:

Repay With ATokens

Repay with ATokens is a new Aave protocol V3 native feature, which allows the user to repay borrowed assets with supplied liquidity of the same asset type in the pool (e.g., repay borrowed USDC with aUSDC). Additional details can be located at New Feature: repay with atoken.

Supported Markets

The repay with ATokens feature is available on all V3 production and testnet markets:

Staking

Existing feature from aave governance V2.
An AAVE or ABPT Aave Balancer Pool Token holder can stake their AAVE or ABPT in the Safety Module to enhance protocol solvency and earn Safety Incentives. Upon the occurrence of a shortfall event, up to 30% of the token holder’s stake can be slashed to cover the deficit, providing an additional risk mitigation mechanism for the protocol.
The staking option is only available on Ethereum Mainnet. Learn more about staking risks [here](https://docs.aave.com/faq/migration-and-staking)

Snapshot Voting

Existing feature from Aave governance V2.
The Aave Snapshot Space is a designated place for voters to gauge the community sentiment for on-chain votes and decide off-chain proposals. Voting on Snapshot proposals is done via a gasless signature and is compatible with a variety of assets and chains. A list of available voting strategies can be viewed here or queried in realtime via this GraphQL endpoint.

On-Chain Governance

Existing feature from Aave governance V2.
Aave Governance allows holders of AAVE or stkAAVE to vote and propose changes and/or upgrades to the protocol and governance. The governance process is described here in more detail.
Aave Governance is only enabled on Ethereum mainnet.

Cross-Chain Governance Bridges

Relatively new feature integrated on chains that support cross-chain messaging.
All voting for Aave Governance proposals occurs on Ethereum mainnet. Governance bridges can be used to take the result of proposal voting on Ethereum mainnet to execute proposals on other chains. This repo contains the technical implementation for cross-chain bridges.
The cross-chain bridge is currently available on the Polygon network.
