      "detailed_summary_en": "Coinbase launched tokenized stocks for Nvidia, Apple, Meta, and Alphabet on its Base layer-2 network, available to non-US users. Approximately $4.5 million was minted and $3 million of DEX liquidity appeared on day one.\n\nA major US exchange bringing tokenized equities of well-known tech companies onto a public layer-2 network marks a significant step for on-chain securities. This development could broaden access for non-US investors and test regulatory and market-structure boundaries in the crypto ecosystem.\n\nChainlink price feeds run 24/5 while the tokenized stocks trade 24/7, creating a potential gap in reference pricing. Base is an Ethereum rollup incubated by Coinbase, processing transactions on its own execution layer while settling through Ethereum.",
