These are the current production contracts used for crypto-paired o1 Launchpad tokens on Base and Robinhood Chain and stock-paired tokens on Robinhood. The separate Base stock suite is deployed, but no Base stock catalog is published yet. These addresses and connections were verified onchain on July 28, 2026.
Always confirm the chain ID and active factory before signing. The same-looking address on another chain is not interchangeable.

​
Base mainnet

Chain ID 8453. View the network on Basescan.

​
Crypto-paired launch suite

This is the active Base route for ETH and USDC pairs.

​
Stock-paired suite readiness

These contracts are deployed, but no Base Stock Token catalog is published yet. A public creation route becomes available only when assets are present in the shared platform catalog, registered on the live factory, and launch creation is enabled. Do not build a creation flow from deployment status alone.

​
Base B20 protocol contracts

The factory checks activation of keccak256("base.b20_asset") before every B20 launch.

​
Uniswap and paired assets

​
Robinhood Chain

Chain ID 4663. View the network on Robinhood Chain Blockscout.

​
Crypto-paired launch suite

This is the active Robinhood route for ETH and USDG pairs.

​
Stock-paired launch suite

This route has 96 registered Robinhood Stock Tokens, free creation (nativeLaunchFee = 0), and new creation enabled. See Stock-paired launches for every paired-asset address.

The current owner controls configuration for future launches. The platform fee receiver receives the platform share of swap fees. Creation fees are currently zero on every available production route. Neither address can modify a completed token or remove its liquidity. Each address links to its chain explorer. Base’s native B20 addresses are also defined in the Base B20 specification, and the Uniswap addresses match the official Uniswap v4 deployment list. See the machine-readable deployment snapshot for normalized addresses and current configuration values.
