Launch on the hub. Trade on three.
A launch is born on Robinhood Chain and extended to Solana and Arc at the same moment, at the same starting market cap. One hub, two spokes, one price, kept in line by a solver.

One hub. Two spokes. One price.
Every launchpad is one chain. A token born on Robinhood Chain is a stranger on Solana. Three launches, three curves, three prices, and the fastest chain runs away.
Introducing Sync

A creator launches once. Three things happen at the same time.
Born on the hub, extended to two spokes
The creator launches on Robinhood Chain in USDG. Sync carries the launch out to Solana and Arc, where the token is created natively too. Supply is unified with an omnichain token standard, so a token moved between chains is the same token, not a wrapped copy.
Same curve, same start
Each chain runs an identical bonding curve quoted in that chain’s dollar stable. Same numbers everywhere, so the token opens at the same market cap on all three. Trading opens on every chain at one shared time, two minutes after launch.
A solver keeps prices aligned
Sync holds inventory of the token and the stable on every chain. When one chain’s price drifts, it buys on the cheap chain and sells on the expensive one until they line up. Every second, every launch.
Three parts. Same numbers on every chain.

The curve
Constant product, $4,000 of virtual quote and one billion tokens per leg. Every leg opens at the same price and graduates when it has raised $20,000.

The solver
A market participant, not an oracle. It trades toward the median of the hub and spoke prices with a cap per trade, so a gap on one chain closes in seconds.

Graduation
Each leg seeds that chain’s DEX at the curve’s final price, with the raised quote plus the fee reserve, and the position is locked forever. No cliff.
The flywheel
The solver’s arbitrage profit is swept the same way: half to liquidity, half to the burn vault. There is no platform token yet, so today the burn share simply accumulates. More launches mean deeper pools and a larger vault. That is the mechanism, not a claim about what any token is worth.

Finally, a launch that is whole.
Who it is for
What it does not promise
4 limits · scrollAlignment needs inventory
The solver can only align prices while it has inventory on each chain. When it runs out on one chain, that chain’s price drifts until inventory is moved back.
Graduation needs a live DEX
A leg graduates into that chain’s DEX. Arc’s is new. If a DEX is not live, the leg’s escrow waits, still non-custodial, and its curve closes at graduation regardless.
Fast movers exist
Chains finalize at different speeds. Someone can buy on one chain before the solver reacts. They pay the curve price plus fee, then the solver trims the gap.
Nothing about price is promised
Sync aligns three prices to each other. It does not hold any of them up. There is no platform token today; the burn share of fees accumulates in a vault until one exists, and it will be described by what fees do to it, never by what it might be worth.
