Coinbase Just Put Apple, Nvidia, Meta and Alphabet Onchain — Stocks Are Now 24/7 DeFi Collateral

The line between Wall Street and crypto just got a lot thinner. On August 24, Coinbase went live with tokenized stocks on its Base network, putting shares of Apple, Nvidia, Meta and Alphabet directly into the DeFi ecosystem. For the first time, the two biggest asset classes on Earth — equities and crypto — can be held, traded and borrowed against in the same self-custody wallet.

The Stock Market Just Learned to Trade 24/7

Traditional equities are boxed into exchange hours, settlement delays and brokerage accounts. The new Coinbase tokens remove all three. Each one is issued under Base's B20 token standard — an extension of ERC-20 that stays compatible with existing wallets, DEXs and routers — and is backed one-for-one by a real share held with regulated custodian Alpaca. That means every holder carries a direct beneficial claim on the underlying stock.

The launch includes four of the most liquid names in the world: Apple, Nvidia, Meta and Alphabet, with more to follow in the coming weeks. Because the tokens trade through onchain markets rather than a centralized exchange, they're available around the clock — not just 9:30 to 4:00. Eligible users outside the US can hold them entirely in self-custody, with no broker sitting in the middle.

How a Tokenized Share Actually Works

Under the hood, B20 keeps things deliberately simple. It extends the ERC-20 contract so a stock token behaves like any other asset in your wallet — you can send it, wrap it, or plug it into a protocol. Dividends and stock splits are handled through an onchain multiplier, so corporate actions adjust your balance automatically without breaking the DeFi positions you've built around it.

The endgame isn't a token that looks like a stock. It's a stock that behaves like money — programmable, 24/7, and collateralizable.

Custody is where the trust sits. The underlying shares are purchased by institutional market makers and held through Alpaca in a bankruptcy-remote structure supervised under the Abu Dhabi Global Market framework. That separation means the shares backing your tokens are ring-fenced from the issuer's own balance sheet — a design choice aimed squarely at making tokenized equities safe enough for serious capital.

Stocks Just Became DeFi Collateral

This is the part that matters for anyone already in crypto. The moment a stock is onchain, it stops being a 'hold and wait' asset and becomes working capital. Aerodrome is already supplying liquidity for tokenized-stock trading, and lending protocols like Aave support borrowing and lending against the assets. In practice that means you can post Apple or Nvidia as collateral for a stablecoin loan, or supply tokenized shares to a liquidity pool and earn yield — the same things you do with ETH, now with a slice of the S&P 500.

The implications ripple outward fast. Automated investment products can rebalance across equities and crypto in a single transaction. Derivatives and structured products can be built on top of tokenized shares without an off-chain legal wrapper. For developers, equities become just another programmable asset, sitting next to stablecoins and crypto in the same codebase.

Where Onchain Equities Go From Here

Coinbase is already signaling that this is the first wave, not the last. Base said more tokenized equities and other real-world assets will launch as its push to bring traditional finance onchain expands. The network is also positioning tokenized stocks as infrastructure for autonomous agents — projects like Virtuals and Treasures are already integrating these assets into agent-based trading systems, letting automated strategies allocate across equities and crypto without human intervention.

For a market that spent years waiting for a bridge between traditional finance and DeFi, the bridge just opened for real. The four biggest names in tech can now be held in the same wallet as your stablecoins, traded at 3 a.m., and used as collateral for an onchain loan. That's not a headline about another token launch — it's the stock market, rewired.
