Chainlink Enables DeFi Borrowing Against Tokenized Stocks

Chainlink has enabled decentralized finance (DeFi) borrowing against tokenized versions of Apple and Nvidia stocks on the Base blockchain. The move allows users to pledge their ownership stakes in these major technology companies as collateral for loans.

The four digital assets, NVDAc, METAc, AAPLc, and GOOGLc, represent ownership rights in Nvidia, Meta, Apple, and Alphabet respectively. These tokens were introduced by Coinbase on August 24th and are issued under the B20 standard by Coinbase Onchain SPV Ltd., an Abu Dhabi-regulated entity.

Chainlink's oracle infrastructure provides total return valuations for each token by combining current stock market prices with adjustment multipliers sourced from Coinbase's blockchain-based oracle registry. This ensures that lending protocols receive precise valuation metrics and can establish borrowing thresholds, monitor position health metrics, and execute liquidation procedures when collateral valuations decline.

Major DeFi platforms such as Aave, Morpho, and Euler are integrating support for B20 tokenized assets, allowing users to pledge their tokenized stock holdings within compatible lending protocols and obtain loans against their positions. However, American investors face restrictions from participating due to Regulation S compliance requirements.
