Why Robinhood Chain
What building natively on Robinhood's Arbitrum-based Layer 2 gives every Pinarc launch.
Robinhood Chain is the Layer 2 Robinhood built on Arbitrum technology to bring its users, tokenized stocks and other real-world assets on-chain (mainnet since July 2026). Pinarc is built natively on it.
The users are already there
Robinhood is onboarding a retail audience that has never touched a bridge. A launchpad on the chain those users land on is in front of them, not somewhere they have to travel to. Within weeks of mainnet, memecoins were most of the chain's DEX volume — the demand for launches is real, and so is the demand for launches that don't end in a rug.
USDG, the chain's native stablecoin
Robinhood selected USDG (Global Dollar, issued by Paxos; Robinhood is a Global Dollar Network partner) as the chain's native stablecoin. It is a 6-decimal ERC-20 at 0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168. Every price, raise, fee, floor and refund on Pinarc is denominated in it, so a buyer takes one risk (the new token) instead of two, and a creator raises dollars, not a volatile gas token. Gas is paid in ETH.
Uniswap V2 for graduation
Graduated tokens migrate their liquidity to Uniswap V2 on Robinhood Chain (router 0x89e5DB8B5aA49aA85AC63f691524311AEB649eba) in the same transaction that sells out the curve. The whole lifecycle of a token stays on one chain. See Graduation.

How Pinarc differs from the other launchpads on the chain
As of September 2026 the active launchpads on Robinhood Chain (PONS, Pools.trade, hood.fun, the stock-paired venues) all quote launches in ETH or in tokenized stocks, and none of them puts creator money at stake.
| Pinarc | Others on Robinhood Chain | |
|---|---|---|
| Quote asset | USDG on every launch | ETH / WETH, or tokenized stocks (PONS v2 can optionally pair a stablecoin) |
| Sniper protection | 30 s batch auction at one clearing price + 120 s anti-sniper window on every launch | Pools.trade Crowd Launch runs a 4-hour TWAP auction; others none disclosed |
| Creator bond | Slashable USDG bond, paid to the holders' floor reserve | — |
| Floor | USDG floor reserve redeemable by any holder | — |
| Team vesting | Enforced by the vault from launch | — |
| Dev buy | Disclosed on-chain, in the launch event | — |
| LP | Locked with a public certificate, or burned | Pools.trade and hood.fun lock liquidity |
| Admin keys | None on curves, vault, locker, floor | Varies; Noxa, the first big launchpad, went dark two weeks after mainnet with ~$12M in fees |
