Aave co-founder and CEO Stani Kulechov really wants Tesla to join the decentralized finance (DeFi) craze.

Kulechov tweeted at Tesla CEO Elon Musk offering to tokenize Teslas as collateral in Aave (LEND) to borrow assets such as U.S. Dollar Coin (USDC) and even invited Musk to learn about DeFi.

Musk, however, has not yet responded to Kulechov’s tweet. Musk, while very friendly to the crypto world, has not publicly commented on DeFi.

Aave’s lending protocol allows for non-collateralized borrowing where parties enter agreements where the borrower can use the lender’s credit line. Kulechov said that the model could help bring DeFi into the mainstream because it makes lending flexible. Kulechov has been a strong proponent of more DeFi education and believes DeFi can play nice with more traditional financial systems.

It won’t be a surprise to link DeFi to Tesla, especially since Musk is a known supporter of cryptocurrencies. Financial charting provider TradingView said Bitcoin and Tesla are two of the most popular assets on the platform.
