One coin.
Two chains.
One click.
Launch once. Hinge creates your coin on Pons (Robinhood Chain) and on pump.fun (Solana) in the same minute, with the same name, ticker and logo. You pay the creation fees of both chains in one deposit, from one wallet.
Every chain splits the trenches in two.
A new coin lives where it was launched. Robinhood Chain has Pons and its crowd, Solana has pump.fun and another one. Launching on both means two wallets, two tools, two sets of fees and a lot of copy and paste.
One chain, half the market
Launch on Pons and Solana traders never find it. Launch on pump.fun and Robinhood Chain traders never do.
Two launches by hand
Two wallets, two uploads of the same logo, two sets of fees in two different coins, and one of the two always lands later.
Hinge: one launch, both chains
One form, one logo, one deposit in ETH. The same coin is created on both launchpads, Pons first.
Three moves, one wallet.
You connect MetaMask, upload a logo and pay one deposit in ETH on Robinhood Chain. You never need SOL or a bridge: the deposit covers the pump.fun fees too.
Connect and pay
Connect MetaMask, and Phantom if you want your share of the pump.fun creator fees. One transfer in ETH on Robinhood Chain, with a reference, pays the creation fees of both chains.
Launch on both
The keeper pins your logo once, launches the coin on Pons through the HingeLauncher contract, then creates it on pump.fun, with the same name, ticker and logo.
Share the fees
pump.fun creator fees are shared on-chain between your wallet and Hinge. On Pons the creator tax goes to the coin's vault and is split between your Robinhood address and Hinge.
After the launch the two coins are two independent coins on two curves. Hinge does not trade them and does not keep their prices together: nothing here promises the same price on both sides.
Not a mock-up. Real curves, real contracts.
The Robinhood Chain contract is tested on a fork of mainnet against the live Pons. The Solana transactions are simulated on live pump.fun state.
HingeLauncher on Robinhood Chain
Launches a coin on the real Pons and points its creator fees to a fee vault. Tested on a fork of the live chain.
Solana simulations
create_v2, buy and sell for a pump.fun coin run clean against mainnet state.
One logo, pinned once
The same image and metadata are used on both chains.
Automated tests
Launch pipeline with retries and refunds, deposit detection, API limits, curves and fees.
Real curves, real numbers.
Both curves hold a billion tokens. They differ in the quote asset (ETH, SOL), in the fees and in where they graduate, so the same coin opens at a different value on each side.
An operator, said plainly.
Two chains cannot be tied by one contract. A keeper runs the launch. Here is what it can and cannot do.
| The keeper can | The keeper cannot | |
|---|---|---|
| On pump.fun | Create the coin from its own wallet | Take your share of creator fees: it is fixed once by pump.fun's fee sharing |
| On Robinhood Chain | Launch the coin through the HingeLauncher contract | Send vault funds to any address except the Hinge address set at deployment |
| Your deposit | Spend it on the creation fees of both chains | Hide where it went: every move is a public transaction |
| Your coin | Nothing after the launch: it does not trade it | Set or hold up the price of either side |
The trade-off is real: you trust the keeper to run the launch after you pay. The docs list the limits, the risks and what is audited.
Fees come back to the creator on both chains.
On pump.fun the creator fees are shared on-chain between you and Hinge. On Pons the creator tax goes to the coin's vault and is split between your Robinhood address, if you give one, and Hinge.
You, on Solana
Half of the pump.fun creator fees, claimable from your own wallet through pump.fun.
Hinge
The other half is Hinge's fee for running the launch.
You, on Robinhood
Give an address and a share for the Pons creator tax. Leave it empty and all of it goes to Hinge.
These are the parameters of the launch. They are written in the docs and in the contracts.
