Pump.fun Lets Memecoins Trade Against Tokenized Stocks on Solana

Pump.fun has introduced “Custom Pairs” on Solana, allowing creators to launch tokens that trade directly against tokenized stocks, major cryptocurrencies and metals. The initial rollout supports 93 asset pairs through the xStocks and Sunrise platforms.

Tokenized Stock Offerings

Twenty new stock tokens have been issued by Backpack Securities via Sunrise. The list includes Boeing, Alibaba, Costco, Dell, IBM, Johnson & Johnson, Lockheed Martin, Reddit, Rivian, Shopify and UPS. Backpack states the tokens are redeemable 1:1 for the underlying shares and can be transferred to traditional brokerages.

Trading Mechanics

Creators can pair a new token with assets such as NVDAx or TSLAx instead of using SOL or a stablecoin as the quote asset. Trading fees may be paid in the paired token and follow the same bonding‑curve and Pumpswap protocol fees as standard launches. Half of the revenue from Custom Pairs is allocated to a programmatic PUMP buyback‑and‑burn contract. Creators may set fees between 0.05% and 1% or choose a cashback model that returns fees to users.

Economic Considerations

DeFi commentator Ignas warned that the model’s reliance on high trading volume could be fragile. He noted that if volume declines, payouts and buybacks would diminish, reducing incentives for token holders.

Regulatory Context

The launch follows a recent dispute involving Robinhood’s tokenized equities, where AMC CEO Adam Aron demanded the removal of an AMC‑linked token, citing lack of authorization and shareholder rights. Robinhood described its stock tokens as debt securities offering economic exposure, while Backpack claims its Solana stock tokens are fully backed and redeemable.

Implications

By merging memecoin speculation with tokenized real‑world assets, Pump.fun expands 24/7 trading of equities on a blockchain, raising questions about how traditional market regulations will apply to such programmable assets.
