Chains & Launchpad
Robinhood Chain
The only chain the engine operates on.
| Chain ID | 4663 (0x1237) |
| Currency | ETH |
| RPC | https://rpc.mainnet.chain.robinhood.com |
| Explorer | Blockscout (explorer.mainnet.chain.robinhood.com) |
Connecting your wallet to the app prompts a network switch to 4663 — MetaMask and most providers add the network automatically.
Pons v2
Tokens launch on a bonding curve with a native ETH pair. Buys and sells happen directly on the curve contract:
buy(quoteIn, minTokensOut, recipient)— payable, ETH insell(tokensIn, minQuoteOut, recipient)— token out → ETH
When a curve hits its graduation threshold (observed ~4.2 ETH), liquidity migrates to a Uniswap v4 pool owned by Pons's pool manager, and the token trades there from then on.
Launch protection
New curves carry a decaying snipe tax — starting near 99% and decaying over the first seconds, readable on-chain via currentSnipeTaxBps. Launches through the engine mark the bundle wallets in snipeTaxExemptions (max 32) so the opening buys are never taxed.
Whitelist
Public launching is currently gated — the factory's canLaunch(deployer) decides. The app checks this before the wizard's final step and tells you plainly if your wallet is not whitelisted.
Funding source chains
Wallet 0 can be funded with ETH on any of:
| Chain | ID |
|---|---|
| Base | 8453 |
| Ethereum | 1 |
| Arbitrum | 42161 |
Distribution to the other bundle wallets happens cross-chain through relay.link. You only fund once — the engine handles bridging and splitting.
