Buying with ETH

A token paired with SPY trades against SPY. A token paired with CASHCAT trades against CASHCAT. Taken literally that means only people who already hold the pair asset can buy — which would make those launches unreachable to almost everyone.

They are not. You can pay in ETH, and the site routes it for you. This page explains what happens when you do.

The route

Buying a SPY-quoted token with ETH takes two swaps:

ETH  →  SPY        on the SPY/WETH pool     (Uniswap V3)
SPY  →  the token  on the token's own pool  (Uniswap V4)

Both happen inside one transaction. You sign once, ETH leaves your wallet, the token arrives, and you never hold SPY at any point you could observe.

Selling runs the same route backwards: the token into SPY, SPY into ETH, paid out as ETH.

Why it needs its own contract

The two legs are on different versions of Uniswap, and that is the whole difficulty.

Every tokenized equity and every memecoin on this chain trades on a Uniswap V3 pool — SPY has around 226 WETH of liquidity at the 0.05% tier, MSTR 123 at 1%, TSLA 17 at 0.3%. Meanwhile every launch that can be paired against one of them is a Uniswap V4 pool, because V4 is where the platform opens equity- and memecoin-quoted pools.

Uniswap's V3 router cannot touch a V4 pool. The V4 router cannot touch a V3 one. A route crossing between them needs something that speaks to both, and on this chain nothing did — which is why this was not possible before.

CrossVenueRouter is that piece. It is deliberately thin: it does not derive pool keys, hold positions, or implement a swap of its own. It wraps your ETH, hands the first leg to the same V3 router the stock buy flow already uses, hands the second to the same V4 router every token trade already uses, and passes the result to you.

What that buys you over doing it yourself

You could do both swaps by hand — buy SPY on the swap page, then use it to buy the token. Three signatures instead of one, and one real risk: if the second swap fails, you are left holding an equity you did not want and may not be entitled to hold.

Routing it in a single transaction removes that. Either the whole route completes or none of it does. There is no state in between where you own the intermediate.

Slippage

Your slippage tolerance is checked once, on the token you finally receive — not on each leg.

That is deliberate. A bound on the intermediate would reject routes that are perfectly fine end to end, while still not limiting the thing you actually care about, which is how much token your ETH buys. If the final amount would come in under your tolerance, the whole transaction reverts and you keep your ETH.

Two pools means two sets of fees and two spreads, so a cross-venue buy will always price slightly worse than a direct one. The quote you see already accounts for both.

When ETH is not offered

The spend selector only offers ETH where the route can actually be executed. Three things have to be true:

1. The token's pool is on Uniswap V4 — which every equity- and memecoin-paired launch is.
2. The pair asset has a funded WETH market on this chain. This is the one that fails: 19 of the 30 tokenized equities have no WETH pool here at all, so there is no first leg to route through. The ones that do are MSTR, SPY, NVDA, SPCX, COIN, CRCL, META, QQQ, GME, TSLA and AAPL. Every memecoin offered as a pair has one.
3. The router is deployed on that chain. It is on Robinhood Chain.

Where any of them is missing, the card offers only the pair asset — because an option that cannot be executed costs you a signature and a reverted transaction to discover.

Funding a dev buy

The same problem appears at launch. A dev buy on an equity- or memecoin-quoted pool is paid in that asset, so the launch form buys exactly what you are short of on the asset's own market first, then continues.

That one is a separate transaction rather than part of the launch, on purpose: folding it in would mean the token factory acquiring assets mid-launch, and that contract holds every pool the platform has opened. A swap beforehand costs one more signature and risks nothing.

Quick answers

Do I ever hold the stock? No. It exists only inside the transaction, and the transaction either completes or reverts entirely.

Can I sell back to ETH? Yes — the receive selector on a sale offers both ETH and the pair asset.

Is it more expensive than a direct buy? Slightly. You cross two pools, so you pay two sets of fees. The quote shows the real figure before you sign.

What if the price moves between the two legs? Your slippage tolerance is checked on the final amount, so a move large enough to matter reverts the whole thing.

Does this work on every chain? It needs the router deployed and the pair asset to have a WETH market. Today that means Robinhood Chain.
