Teller vs Aave - Redefining the Future of Crypto Lending and Borrowing Platforms

The recent years in the crypto space have seen the emergence of Decentralized finance (DeFi) as one of the hottest topics. DeFi imagines and promotes an open global financial system capable of functioning without intermediary parties such as clearing houses, banks, and insurance companies. DeFi companies strive to build a simple, swift, and secure financial ecosystem that is accessible to everyone with the internet on their devices. It is trying to bring the entire traditional financial market to the blockchain systems to ensure efficiency, transparency, and decentralization. A system like this is accessible on the internet to everyone with little knowledge about crypto assets.

In this article, we will discuss two leading DeFi lending and borrowing protocols that are changing the world of finance with decentralization and smart contracts as we see them today, Aave and Teller. Before we jump to the comparison between Aave and Teller, we first need to understand the underlying mechanism and process running on both of these protocols.

What is Teller

Teller protocol is a decentralized protocol that is making uncollateralized and undercollateralized loans accessible to the masses. It enables secured and unsecured DeFi digital asset borrowing and lending using an open order-book model.  The platform also helps borrowers to bridge their off-chain data onto on-chain crypto loan requests.

Borrowers can request crypto loans on the platform by filling in the details on the platform, while the lenders supplying assets to meet the loan demands can commit to a request of their choice. There is a direct transaction between the borrowers and the lenders if the latter decides to comply with the loan conditions of the former.  The borrower’s information includes details such as identity information, credit history, other loans active and other relevant data.

Product demonstration of Teller's borrower request form

Teller hosts three types of users on its lending protocol.

  1. Marketplace owners such as creators, entrepreneurs, and developers who wish to launch a new lending pool. They can initiate their lending book within the protocol by building a simple front-end user interface. The users can then borrow market-specific crypto loans by connecting the required data support.
  2. Lenders fill requests raised by borrowers or create their criteria for commitments based on the rules and requests of asset data. They can place another request serving as a counter to the requests raised by the borrowers.
  3. Borrowers are the ones who request loans via the Teller’s platform. Borrowers can choose a pool on Teller’s marketplace that is favorable to their conditions. Some of the pools currently hosted by Teller are Ape Now- which allows you to buy NFTs instantly and pay later. USDC Homes- this market allows uncollateralized crypto loans for residential mortgages, Koala B2B is a travel protection crypto loan, etc.  

What is Aave

Aave is a decentralized finance protocol letting people borrow and lend crypto. Lenders on this platform can earn interest by depositing their crypto assets into the liquidity pools created by liquidity providers on the platform. Borrowers then have to use their crypto as collateral to receive a crypto loan using liquidity.

Aave was launched in the year 2017 and was originally known as ETHLend. However, it was rebranded to Aave in the year 2018. Aave also provides its holders with some discounts on the platform. The AAVE token serves as its governance token, giving voting rights for future developments and operational changes within the protocol. Aave became one of the most popular DeFi lending protocols during the DeFi craze of 2020, as it was one of the first liquidity pool-driven lending platforms on the Ethereum blockchain. It emerged as one of the biggest decentralized finance projects in terms of total value locked in the protocol.

Aave allows its users to lend and borrow in almost 20 crypto assets. One of the unique offerings of Aave is the Flash Loans. This product was considered one of the first uncollateralized loans in the DeFi space. However, these uncollateralized loans were open only for a few minutes and had to be paid back within a few minutes or hours in the same transaction. Aave also lets its users alternate between variable and fixed rates.

  • Teller has recently collaborated with Chain Link, the world's leading decentralized oracle network, and DECO to create a proof of concept to issue undercollateralized crypto loans using zero-knowledge proofs to attest to off-chain information.
  • Roofstock, one of the world’s leading online marketplace for real estate investors in the single-family rental (SFR) home sector, will be leveraging the Teller protocol to enable the financing of real estate properties using USDC Homes.
