Rotate within a market family
Rotation moves from one registered launch token to another through the quote asset they share. It is the native route between markets in the same family, without first converting the position to ETH or breaking a Lot into its components.
Launch token A → shared Lot token → Launch token B
For two eligible direct-stock launches, the intermediate asset is their shared stock token.
What rotation changes
The route exchanges your launch-token position through two independent pools. It preserves the shared Lot's recipe and avoids component sales and repurchases. Both swap fees and price impact still apply; the destination token has no direct Lot redemption rights.
Which markets can rotate
Eligibility depends on exact registered identity, not a similar name or theme:
| Source and destination | Dedicated rotation route? |
|---|---|
| Two Lot-paired launches using the same registered Lot vault | Yes, if executable |
| Two direct-stock launches using the same registered stock-token address | Yes, if executable |
| Separate Lots with identical-looking recipes | No |
| Different direct-stock quote tokens | No |
| One direct-stock launch and one Lot-paired launch | No |
| Launches from different factory versions | No dedicated rotation route |
| A token into itself or an unregistered launch | No |
Both launches must be distinct, registered with the same launch factory on the same chain, and connected to official pools validated against immutable factory records. A caller-supplied matching address is not enough. Zero input and zero intermediate quote output are rejected.
The complete route
Review source, destination, intermediate quote amount, both fees, impact, expiry, gas and protected final output. Approve the source token if its allowance is insufficient.
Both swaps settle atomically. If the final minimum cannot be met, the route reverts without leaving an unrequested intermediate Lot. Gas can still be consumed; earlier approvals remain.
Two markets mean two fees
The source sale pays its permanent fee. The destination purchase pays its fixed fee. The destination’s early buying limits apply while active. The source fee is paid in the source launch token; the destination fee is paid in the shared Lot token, or the shared Stock Token for direct-stock pairs.
The fee-only retained fraction is:
(1 − source fee) × (1 − destination fee)
At 1% on both swaps, the fee-only drag is 1.99%; at 4% on both, it is 7.84%. With 2% on each side, a normalized 100 becomes 98 after the first fee and 96.04 after the second, a 3.96% drag. This illustration holds exchange ratios constant and excludes price impact, gas, and rounding; it is not an executable quote.
Changing between launches quoted in different Lots is a different set of transactions with its own markets and costs. It does not alter either Lot. Trading in Lot units explains the difference between the speculative position and the asset used to measure it.
