Glossary

Plain definitions of the words used across these docs. For what is available on which network, see Network and addresses. For common questions, see Frequently asked questions.

Access code. While StartupOS is in early access, the personal code that gets you past the Under development screen. The first wallet that signs in with a code claims it, and the code then works only with that wallet.

Anti-snipe window. The first 2 blocks after a token launches, about 24 seconds. During it, every wallet except the creator can buy at most 5% of the supply and hold at most 5%, counted per wallet. Anyone may buy in the launch block itself. The creator has no cap at all. Sells and transfers are never restricted, and the limits end for good when the window closes.

Approval. Permission for a contract to move a specific token on your behalf, needed before a trade spends that token, such as a sale. On a bonding-curve or Uniswap V3 token, every sale first approves its own exact amount as a separate transaction, whatever the wallet. On a token in a Uniswap V4 pool, a wallet that can batch calls gives it in the same confirmation as the trade, for the exact amount, and other wallets approve the token once and add a Permit2 signature. See Paying for a trade.

Auto-Burn. One of the three token types, and the default. Every trade pays a 1% fee: 0.4% to the creator, 0.2% burned and 0.4% to the platform. Chosen at launch, fixed for life.

Basket. A token backed by fixed amounts of 2 to 8 listed assets, such as tokenized stocks. You can always burn a share back into those amounts. Anyone can create one from the assets StartupOS lists. See Baskets.

Basket-paired token. A launched token whose pair currency is a basket. Its price, fees and creator earnings are all in basket shares, so it carries the basket's risks as well as its own. See Risk disclosures.

Bonding curve. One of the two launch models. The token sells along a price curve that rises 14.7 times as people buy. Each curve is sized when its token launches and sells out after about $14,170 of net buying, at the prices of that moment. The token then graduates into a Uniswap pool.

Burn. Permanently destroying tokens, which lowers total supply. A bonding-curve token burns its burn share, in tokens, on every trade. An Instant token spends its burn share on buyback and burn. Standard tokens have no burn share.

Buyback and burn. Buying a token in its own pool and destroying what was bought. A token in a Uniswap V4 pool builds a budget in its pair currency from its burn share and from the burn half of a Rewards and burn holder tax, then spends it in small, price-limited buybacks. On mainnet this runs for tokens launched since October 18, 2026. Curve tokens in a Uniswap V3 pool spend part of their pool fees this way during each collection.

Circulating supply. Tokens actually in existence and held by someone. It falls over time as tokens are burned.

Claim. Taking money that is owed to you. Holders claim holder rewards and lottery prizes on the Rewards page and pay the gas. A bonding-curve token's creator claims creator earnings. Anyone can trigger a claim, and it always pays the person the money belongs to.

Collect. For a bonding-curve token that graduated to Uniswap V3, the transaction that gathers its pool fees and splits them between the creator, the burn and the treasury. Anyone can run it, and it takes no address, so nobody can redirect the proceeds. It needs a minimum amount to have built up, currently 0.005 WETH. Shown in the app as Run Collect & Burn. After it runs, the creator still claims.

Contract address. The unique on-chain identifier of a token, and the only thing that reliably tells one token from another. Names, tickers and images can all be copied.

Creator. The wallet that launched a token. It has no anti-snipe cap. It earns 0.7% of every trade on Standard, 0.4% on Auto-Burn and nothing on Tax-Free. The creator address of a token in a Uniswap V4 pool can never be changed. The contracts let the creator of a token in a Uniswap V3 pool hand its payout address over in two steps, and doing that from the app is not available on mainnet yet.

Creator earnings. The creator's share of the fee, also called creator rewards. An Instant token pays it in the pair currency once someone delivers it. A bonding-curve token builds it up in its pair currency, usually ETH, until it is claimed, and after graduation into Uniswap V4 it is delivered as on an Instant token. Tax-Free tokens produce none. See Creator rewards.

Deliver. On a token in a Uniswap V4 pool, Instant or graduated, the Deliver earnings to the creator button. It sends the creator's waiting share to the creator. Anyone can press it and pay the gas, and the money always goes to the creator. If a delivery fails, the amount is held until the creator uses Collect held earnings.

Fully diluted value (FDV). Price multiplied by total supply. It is the same number StartupOS shows as Market cap.

Gas. The network fee paid in ETH for any transaction. Separate from StartupOS's trade fee, and payable even on a Tax-Free token.

Graduation. The step where a bonding-curve token that has sold out moves into a Uniswap pool, with its liquidity position going straight to a locker for good. The pool is a Uniswap V4 pool with StartupOS's hook. A curve token launched on mainnet before October 18, 2026 graduates into Uniswap V3 instead. Trading stops between sell-out and graduation. StartupOS's keeper usually triggers the move automatically, and anyone can. The graduation fee is a flat 0.01 ETH on an ETH pair, or 2% of the raise on a market paired with another token, never both. It goes to the treasury with a matching share of the held-back tokens, so the pool opens at the curve's closing price. Instant tokens never graduate. See The pool and the liquidity lock.

Holder. A wallet with a non-zero balance of a token.

Holder rewards. Money paid to a token's holders from its holder tax, in the pair currency. Each UTC day, 90% of the token's rewards pool is shared among wallets whose average position that day was worth at least $100, in proportion to their average balance. The other 10% funds the weekly lottery. You can claim once you are owed at least $20. On mainnet, holder rewards run for tokens launched since October 18, 2026. See Holder rewards and the weekly lottery.

Holder tax. An optional extra 1% or 2% on every buy and sell of an Instant token, on top of the fee, chosen at launch and fixed for life. With Holder rewards, all of it goes to the rewards pool. With Rewards and burn, half goes to the rewards pool and half to buyback and burn. Tax-Free and bonding-curve tokens cannot have one.

Hook. A contract Uniswap V4 runs alongside a pool. Every StartupOS Uniswap V4 pool uses StartupOS's hook, for Instant tokens and graduated curve tokens alike. It charges the fee and any holder tax, enforces the anti-snipe window, holds each share until it is paid out, and lets only the token itself open its pool. A pool's hook is fixed for the life of the token.

Instant launch. One of the two launch models. The token trades in its own Uniswap V4 pool from the launch transaction, with the whole supply placed in the pool and no curve or graduation. On an ETH pair the whole supply opens at a value of about 0.98 ETH. Paired with another token, it opens at about 1 whole unit of that token.

IPFS. The distributed storage where token images live, so artwork is not hosted only by StartupOS.

Keeper. StartupOS's automated service that usually triggers graduation as soon as a bonding curve sells out. Also the name of an app page listing bonding-curve tokens that graduated to Uniswap V3, with buttons to collect their pool fees and pay out the creator's share. Anyone can press them.

Liquidity. The assets available to trade against. Deeper liquidity means your trades move the price less.

Locker. A contract that holds a token's Uniswap liquidity position for good: a Uniswap V4 locker for Instant tokens from launch and for bonding-curve tokens from graduation, and a Uniswap V3 locker for curve tokens launched on mainnet before October 18, 2026. Neither locker has owner functions or any code path that can remove liquidity or move a position out. On a bonding-curve token that graduated to Uniswap V3, the locker also splits collected pool fees.

Lottery. A weekly draw run separately for each Instant token with a holder tax. Weeks run Monday to Sunday, UTC. The pot is 10% of that week's rewards plus anything rolled over. To enter, hold at least $500 of the token at the end of the week. Chances follow dollar-days, where $1 held for one day is one point. Ten different winners each get a tenth of the pot, added to their holder rewards claim. Like holder rewards, on mainnet it runs for tokens launched since October 18, 2026. See Holder rewards and the weekly lottery.

Mainnet. Robinhood Chain's live network, chain ID 4663, where tokens have real value.

Market cap. Price multiplied by total supply. StartupOS shows it on token pages, cards and market lists. A new token shows its starting market cap from launch. A bonding-curve token opens at about $4,660, and an Instant token at about 0.98 ETH on an ETH pair, or about 1 whole unit of any other pair token.

One-confirmation trade. A trade where your wallet approves and swaps in a single confirmation, for the exact amount of the trade. StartupOS uses it on Instant tokens when your wallet can batch calls. Other wallets, Rabby among them, go step by step: the first time, an approval and a Permit2 signature, then the trade. One Permit2 signature covers that token for 30 days, so later trades ask only for the trade.

One-sided liquidity. How an Instant token's pool is seeded at launch: the token goes in and no ETH does. Buyers build up the other side.

Pair currency. What a token trades against: ETH by default, or another token chosen at launch where that is open. An Instant token's fee, creator earnings, holder rewards and buyback budget are all paid in it. A bonding curve can only launch against a pair currency that has a dollar price. Besides the assets on the launch list, a creator can paste in any token, and the app marks one that has not been vetted.

Pay with ETH. The trade panel option for buying a token paired with another token using ETH. In a Uniswap V4 pool it swaps through the pair currency in one transaction. On a bonding curve paired with another token it works for buying only, in one transaction or two steps, and it is not offered after graduation to Uniswap V3. It needs a Uniswap pool between ETH and the pair currency, and testnet does not offer it for tokens paired with another token. See Paying for a trade.

Permit2 signature. A gas-free message some wallets sign before a trade that spends a token on an Instant token, such as a sale. It lets Uniswap's router use your approval for that token, through Uniswap's Permit2 contract. One Permit2 signature covers that token for 30 days, so later trades ask only for the trade. Wallets that can batch calls skip it: see One-confirmation trade.

Pool ID. How a Uniswap V4 pool is identified, in place of an address. Every V4 pool lives inside one shared contract, so an Instant token has no separate pool contract to link to.

Price impact. How far your own trade moves the price. It grows with trade size, and is largest early on when the pool holds little ETH.

Round trip. Buying and then selling the same token. On Standard and Auto-Burn it always loses money, because each leg pays the 1% fee plus any holder tax. On an Instant Tax-Free token only gas and price impact apply.

Slippage. The maximum price movement you will accept between submitting a trade and it landing. If the price moves further, the trade reverts instead of filling at a worse price.

Sniping. Buying in the first seconds after a launch, before others can react. Limited by the anti-snipe window, which caps every wallet except the creator's, and shown on each token's safety card as Bought at launch.

Standard. One of the three token types: 1% per trade, split 0.7% to the creator and 0.3% to the platform, with no burn. Chosen at launch, fixed for life.

Tax-Free. One of the three token types. An Instant Tax-Free token charges no fee on any trade, ever, and nobody earns from it. A Tax-Free bonding-curve token is free to trade on the curve and after graduation. One launched on mainnet before October 18, 2026 graduates into a Uniswap V3 pool that charges 0.05%, all spent on buyback and burn. Tax-Free tokens cannot carry a holder tax. Chosen at launch, fixed for life.

Testnet. Robinhood Chain's test network, chain ID 46630. Its tokens have no value, and free test ETH comes from a faucet. A few features work differently there: see Network and addresses.

Trade fee. The fee on each trade, fixed at launch. On an Instant token the hook takes it in the pair currency, and the Uniswap pool's own fee is zero. On a bonding-curve token it is added to a buy and taken from a sell. See Fees and burns.

Treasury. The platform's address, receiving its share of fees. Published on Network and addresses.

Uniswap V3. Where a bonding-curve token launched on mainnet before October 18, 2026 trades after graduation. Standard and Auto-Burn pools charge 1%, and Tax-Free pools 0.05%.

Uniswap V4. Where Instant tokens trade from launch, and where bonding-curve tokens graduate. Every pool lives inside a single shared contract and is identified by a pool ID.

Virtual reserves. The two numbers that set a bonding curve's price: 1,073,000,000 tokens, and $5,000 worth of the pair currency, priced when the token launches and then fixed for that token. Each buy takes tokens out and puts the pair currency in, so the price rises. See Launching a token.

WETH. Wrapped ETH, the form ETH takes inside a Uniswap V3 pool, so curve tokens that graduated into Uniswap V3 use it. StartupOS's Uniswap V4 pools use plain ETH. The app wraps and unwraps for you when needed.
