Chains, Lenders, Assets

In this section we list the supported chains, lenders and assets for the borrow flow.

Chains

As of Concrete v1, the protocol will run its own appchain allowing for multichain integrations.

The roadmap of upcoming supported chains includes (in no particular order):

• Berachain

• Avalanche

• Arbitrum

• Optimism

• Ethereum Mainnet

• Solana

For development purposes the supported chain is Ethereum Sepolia

Lenders

The supported lenders for the borrow flow for Concrete v1 are:

• AAVE v3

• Compound v3

• Radiant

• Silo Finance

For testing purposes, the supported lender is AAVE v3

Assets

The protocol supports assets for taking out loan positions on the underlying lending platforms, at different levels:

Collateral assets

These assets are essentially all of the assets that can be supplied in the supported lending platforms and are classified as:

• Unprotected: While available to be used as collateral assets for loan positions on any supported lender through Concrete, the protocol doesn't offer any protection to positions using these assets as collateral.

  • Foreclosable: This is a sub-type of the unprotected assets for which the protocol offers the Concrete Lite feature, avoiding liquidation on the lending platform by repaying the loan when approaching the lender's liquidation threshold. Read more about Loan Foreclosures. These assets are marked in the backend as "is_foreclosable = true" and are also included in the foreclosable whitelist at a smart contracts level.

• Protectable: For positions taken using these type of assets as collateral, the protocol offers Concrete Protect, that allows borrowers to apply a protection plan to the loan. Read more about Loan Protection. These assets are marked in the backend as "is_protectable = true" and are also included in the protectable whitelist at a smart contracts level.

Debt assets

These are the assets that, from the supported collateral types, Concrete allows to be borrowed in loan positions.

These assets are made available to the frontend from the backend and are classified as "Borrow Assets".

At a smart contract level, they are included in the debt tokens whitelist.

Blacklisted assets

These are the assets that Concrete will not allow to be used either as collateral or debt assets across the whole system.

These assets are included in a blacklist at the smart contracts level.
