Two kinds of stock token
Coinbase B20 stocks
NVDAc, COINc and friends - issued in the Coinbase app as chain-native
B20 tokens. No on-chain DEX market yet: buyers must already hold
the stock, and ETH cannot route into it.
ST0x wrapped stocks
wtCOIN, wtNVDA, wtMSTR, wtSPCX - 1:1 backed wrapped equities with
real DEX liquidity. Anyone can buy a token paired with these using
plain ETH.
How a pair becomes launchable
Every launchable pair is registered in an on-chain oracle registry naming its Chainlink feed and how stale an answer may be before it must not be trusted:- Crypto feeds get roughly a day.
- Equity feeds get 96 hours, because they hold Friday’s close over a weekend by design.
$BSTONK itself is priced by a purpose-built adapter reading the
BSTONK/USDC pool’s own price times the USDC feed. It is a spot price: a
determined trader can move it within a transaction, which can misprice
the opening of a new launch that chose this pair - never a pool that
already exists.
