What “graduated” means
When a curve’s backing value hits $6,000, liquidity leaves the bonding curve and seeds a Uniswap V4 pool — permanently locked.

How the threshold is measured
Backing value is the USD value of stock tokens sitting in the curve, using the market’s price oracle (Chainlink stock/USD feed). Progress on Explore and the token page is that value divided by $6,000.
Buys can trigger graduation
On-chain graduation

require(

);
_graduate();
}Internally the curve seeds the V4 pool at the final curve spot when inventory allows: it deposits all backing stock and only enough meme tokens to match that price. Leftover unsold sale tokens (and any unused LP slice) go to a dead address instead of dumping into the pool — so expensive tickers no longer open at a discount to the curve mark.
// vs = VIRTUAL_STOCK + realStock; vt = VIRTUAL_TOKEN + unsold
// ideal = realStock * vt / (vs * leverage)
tokensForPool = min(onCurveBalance, ideal);
// excess → DEAD; stock + tokensForPool → V4Graduator.graduate(...)
// realStockReserve = 0; graduated = true;Deploy note
