DeFi (blockchain-based financial services) venues on Coinbase’s Base network hold $960,300 worth of Coinbase-issued stock tokens, with Uniswap accounting for $943,200, or roughly 98.2%. The remaining $17,100 is spread across other protocols. Coinbase launched B20-standard tokens representing fractional ownership in Apple (AAPLc), Nvidia (NVDAc), Meta (METAc), and Alphabet (GOOGLc) for eligible non-US users. The tokens can trade around the clock and are backed 1:1 by underlying shares held by broker-custodian Alpaca in a bankruptcy-remote structure regulated by Abu Dhabi Global Market (financial center and regulatory jurisdiction). B20 is a Base-native extension of ERC-20 that supports onchain corporate actions such as dividends and stock splits. Launch integrations included liquidity on Aerodrome and Uniswap and lending on Aave, Morpho, and Euler. About $4.5 million was minted at launch, with $3 million in DEX (decentralized exchange) liquidity and $10.8 million in 24-hour trading volume. The much smaller DeFi deposit balance suggests many minted tokens remain in wallets rather than deployed in protocols. Aerodrome’s gauge-based emissions system could help redirect liquidity incentives toward stock-token pools.
