How it works

One pool, three market states

Open

Tracks the exchange

Quotes a few basis points around the live Nasdaq price. Nothing stale to pick off.

Closed

Finds the price itself

Trades move the pool's own curve, and the spread widens with the square root of time.

Halted

Stops with the exchange

Nasdaq halts the stock, the program refuses swaps. Withdrawals always work.

Proof

Same money, same prices, same traders

Three years of real NVDA prices replayed minute by minute through four pools, each starting with $100,000. Faster traders always know the true price. Bellcurve runs the exact code deployed on-chain.

NVDA · liquidity providers vs simply holding
Constant-product 0.30%-53.6%
Constant-product 1.00%-61.0%
Oracle pool, no market hours-165.8%
Bellcurve-11.9%
Regulation-ready

Built for the SEC's new exemption

On September 17, 2026 the SEC opened tokenized US stocks to permissioned AMMs on public blockchains, with conditions attached. Bellcurve already meets them in code.
