Network and addresses
StartupOS runs on Robinhood Chain. "Robinhood" here refers to the chain only. StartupOS is not affiliated with, endorsed by, or connected to Robinhood.
StartupOS is deployed on two Robinhood Chain networks: mainnet, where tokens have real value, and testnet, where they have none. Check which network your wallet is on.
You do not need to enter network details by hand. The Add network button in the app asks your wallet to add the chain with the correct settings.

Payouts on mainnet. Every token launched since October 18, 2026 pays its holder rewards, weekly lottery prizes and buybacks through the rewards distributor and buyback executor of the factory that launched it, listed below. A token launched before then keeps collecting its holder tax and burn share, which are held for it, but its payouts have not started yet. Creator earnings and the platform's share are paid as normal on every token.
How testnet differs. Paying with ETH does not work there for a token paired with another coin, because the Uniswap router on testnet points at mainnet contracts. New features usually reach testnet first.
StartupOS's contracts have had internal security reviews but no external audit. See Risk disclosures.

The source code of every contract in this table is verified on Blockscout, Etherscan and Sourcify.
A token's terms come from the factory that launched it, and never change. A factory and its hook, deployers and lockers are a matched set, and a token's type, fee, fee split, holder tax and anti-snipe window are fixed at launch. A later change to StartupOS's settings only applies to tokens launched after it.
Earlier mainnet factories
Tokens launched before November 2, 2026 came from an earlier factory. A token from any factory on this page is a genuine StartupOS token, and keeps the terms it launched with.
The October 18, 2026 factory works the same way as the current one. Its bonding-curve tokens graduate into Uniswap V4, and its tokens pay holder rewards, weekly lottery prizes and buybacks through its own rewards distributor and buyback executor. It uses the same lottery randomness, FOMO jackpot, basket factory and asset registry as the current factory.

Each of these factories points to its own hook and lockers, which you can read on the factory's explorer page. Bonding-curve tokens from these factories graduate into Uniswap V3. Tokens from the October 4 factory send their holder-reward and burn shares to a rewards distributor at 0xEC4A4F25e393a19b4e9d17012E26C1224eA43619 and a buyback executor at 0x4003D8470709740d7a9c068a442e091F454E3b58, and tokens from the other earlier factories keep those shares in their hook. Either way the shares are held for each token, and payouts for these tokens have not started yet.

What each contract does
Factory. Every launch goes through it, and each token is its own contract. The factory creates Instant tokens through the Instant token deployer and bonding-curve tokens through the curve token deployer. Mainnet factories from before October 18, 2026 created bonding-curve tokens themselves.
Liquidity lockers. They hold every token's Uniswap liquidity position for good: from launch for an Instant token, and from graduation for a bonding-curve token. No locker has owner functions, and none has any code path that can remove liquidity or move a position out. Every factory since October 18, 2026 places graduated tokens in its Uniswap V4 locker. Mainnet factories from before then also have a Uniswap V3 locker for the curve tokens they graduate. See The pool and the liquidity lock.
Hook. It is attached to every Uniswap V4 pool StartupOS opens. It charges the fee and any holder tax in the pair currency, enforces the anti-snipe window, and keeps each share until it is paid out. It also lets only the token itself open the token's pool. Without that, an attacker could create the pool first at a price of their choosing and make the real launch fail. A hook is part of a Uniswap V4 pool's identity, so it is fixed for the life of the token.
Rewards distributor. It holds each token's holder rewards and weekly lottery prizes, and pays them out when holders claim. On mainnet, the current factory and the October 18, 2026 factory each have their own, listed above, and each pays for the tokens its factory launched. See Holder rewards and the weekly lottery.
Buyback executor. It spends each token's burn budget buying the token in its own pool and burning what it buys. On mainnet, the current factory and the October 18, 2026 factory each have their own, listed above, and each runs for the tokens its factory launched. See Fees and burns.
Lottery randomness. It asks an on-chain randomness oracle built on the Pyth Entropy design for the number that picks each week's lottery winners. See Holder rewards and the weekly lottery.
Quote zap. It lets you pay with ETH for a bonding-curve token paired with another coin, in one transaction: it swaps your ETH into the pair currency and buys the token for you. Each quote zap works only for tokens from its own factory. For any other token paired with another coin, the app pays in two steps instead. See Paying for a trade.
FOMO jackpot. It holds each round's prize pool and pays the winners when the round ends. See The FOMO jackpot.
Basket factory. It creates baskets. Each basket is its own token contract and holds its own assets. See Baskets.
Basket zap. It lets you buy a basket with ETH, so you pay in one asset instead of buying each of a basket's holdings yourself. It does the same job for a token paired with a basket: paying in ETH, it buys every holding, mints the basket and buys the token in one transaction, and selling, it runs the whole path in reverse and pays you in ETH. On mainnet, its route for basket-paired tokens covers tokens from the current factory.
Asset registry. The list of assets a basket may hold, and the price feed for each one. It is also the list of assets you can pair a new token with on the launch page, where they appear under Stocks, ETFs and Crypto. On mainnet it lists 34. Anything not in it cannot be put in a basket.
Treasury. It receives the platform's share of fees. See Protocol revenue and buyback and burn.
Uniswap V4
Uniswap V4 is deployed at the same addresses on mainnet and testnet. StartupOS uses it for Instant tokens and for graduated bonding-curve tokens.
| Contract | Address |
|---|---|
| PoolManager | 0x8366a39CC670B4001A1121B8F6A443A643e40951 |
| Position manager | 0x58daec3116aae6d93017baaea7749052e8a04fa7 |
| Universal router | 0x8876789976decbfcbbbe364623c63652db8c0904 |
| Quoter | 0x8dc178efb8111bb0973dd9d722ebeff267c98f94 |
| StateView | 0xf3334192d15450cdd385c8b70e03f9a6bd9e673b |
| Permit2 | 0x000000000022D473030F116dDEE9F6B43aC78BA3 |
V4 keeps every pool inside the single PoolManager and identifies each one by a pool ID, so a StartupOS V4 pool has no address of its own.
Use the universal router above. Mainnet also has a second universal router at 0x66a9893cC07D91D95644AEDD05D03f95e1dBA8Af. Its pool manager is an address with no code, so any V4 swap routed through it fails. The app already uses 0x8876…, so this matters only if you route trades yourself.
To route a trade to a token in a StartupOS V4 pool yourself, you need its full pool key: both currencies, the pool fee (0), the tick spacing (200) and the hook of the factory that launched it. The token address alone is not enough, but each token returns its own pool key from its poolKey function.
Verifying a token
Before you buy anything:
- Open the token page and copy the contract address from the header.
- Open it on the explorer for the right network, and check who created it. A StartupOS token is created by a factory on this page, current or earlier, or by one of that factory's token deployers.
- Check the holder distribution, including how much the creator holds. A token where a few wallets hold most of the supply carries far more risk.
A name, a ticker, an image and a social link can all be copied. The address cannot. See Risk disclosures before you trade.
