Plain-language definitions for the terms you will meet while launching, trading, or holding ARCHR on Archr. For contract-level detail, see [Contracts](/network/contracts). ## A ### Airdrop The scheduled payout of the [ARCHR fee-flywheel](/earn/archr-flywheel). Every time a launched coin's fees have been recycled into 1% of its supply (10,000,000 tokens), the top-50 ARCHR holders receive that stack pro-rata to their ARCHR balance. An airdrop is always in the coin that triggered it, not in ARCHR. ### `AlreadyLaunched` The on-chain revert raised by every launcher factory when a launch is retried against a dedupe key that has already produced a coin. The launch's own trigger surface (site / Reddit / X) enforces dedupe off-chain first; the on-chain revert is the crash-safety backstop. See [launch overview → dedupe](/launch/overview#dedupe). ### ARCHR The [Archr platform token](/network/contracts#archr-token). Holding ARCHR is the sole eligibility condition for the [fee-flywheel airdrops](/earn/archr-flywheel). ### Archr The launchpad platform itself — the on-chain launcher contracts, the archr.win frontend, the Reddit and X trigger bots, and the fee-flywheel keeper. See [Introduction](/introduction). ## C ### Coin A token launched through Archr. See [Contracts → Coin](/network/contracts#coin) and [FAQ → what does a coin look like on-chain](/reference/faq#what-does-a-coin-look-like-on-chain). ### `collect(id, to)` The owner-only call on every launcher factory that sweeps a locked position's accrued swap fees to a destination address. Because the position is locked forever, `collect` cannot decrease liquidity — it can only realize the `tokensOwed` fee bucket. Feeds the [ARCHR fee-flywheel](/earn/archr-flywheel). ## D ### Dedupe The rule that each trigger event can produce at most one coin — one per launch form submission, one per Reddit comment, one per tweet. Enforced off-chain by the platform and on-chain by the launcher factories. See [launch overview → dedupe](/launch/overview#dedupe). ### Dev-buy The site's optional launch feature: buy a share of your coin's supply in the same transaction that deploys it. The deploy and the buy succeed together or neither happens — a swap-side revert unwinds the whole transaction and no coin is deployed. Only available on the site trigger. See [dev-buy](/launch/dev-buy). ### Distributor The address the [fee-flywheel program](/earn/archr-flywheel) uses as its working balance — collected fees land here, WETH is swapped into coin here, and the top-50 airdrop is sent from here. See [Contracts → distributor](/network/contracts#archr-fee-flywheel-distributor). ## F ### Fee tier Every Archr coin trades on a Uniswap V3 pool at the **1% fee tier** (`fee = 10000`, `tickSpacing = 200`). A 1% cut on every swap goes to the locked LP position — that is what feeds the fee-flywheel. See [trading overview](/trade/overview#fees). ### Fully-diluted valuation (FDV) The market cap the coin would have if every token were priced at the current pool price. Because Archr coins have a fixed 1B supply and 100% is in the pool at launch, initial FDV equals the market cap implied by the launch tick. ## L ### Launcher factory The on-chain contract that actually deploys a coin, creates its pool, and holds the locked LP. Archr has three factories: [`WebFactory`](/network/contracts#webfactory) (fronted by the [`ArchrLaunchpad`](/network/contracts#archrlaunchpad) adapter for the site), [`RedditFactory`](/network/contracts#redditfactory), and [`TwitterFactory`](/network/contracts#twitterfactory). All three share the same locked-LP, fees-only custody surface. ### Launch tick The tick where the single-sided sell wall starts — the lowest price at which a coin can be bought. Derived from a target FDV in USD, read live from Chainlink ETH/USD on 4663, then snapped to a multiple of `tickSpacing = 200`. Because coin is `token1` in the pool and WETH is `token0`, the launch tick is positive. See [launch overview → launch tick](/launch/overview#the-launch-tick). ### `Launched` The event every launcher factory emits after a successful launch — carries the deployed coin address, pool address, LP NFT id, name, symbol, and dedupe key. Indexers key off this event. See [Contracts](/network/contracts). ### Locked LP The LP NFT position held by the launcher factory after every launch. Permanently locked — no address can withdraw or move the principal, and revenue is only the accrued 1% swap fees. See [risks → liquidity is locked, revenue is fees](/reference/risks#liquidity-is-locked-revenue-is-fees). ## N ### NPM Uniswap V3's `NonfungiblePositionManager` — the contract that mints LP positions as ERC-721 NFTs. On 4663 the canonical NPM is `0x73991a25C818Bf1f1128dEAaB1492D45638DE0D3`. Every Archr launcher factory holds its LP NFTs via NPM. See [Contracts → Uniswap V3 NPM](/network/contracts#uniswap-v3-nonfungiblepositionmanager). ## R ### Robinhood Chain The L2 rollup Archr runs on. Chain ID **4663** (mainnet). Native token ETH. Arbitrum Orbit stack settling to Ethereum mainnet. Canonical docs: [docs.robinhood.com/chain](https://docs.robinhood.com/chain). See [wallet setup](/getting-started/wallet-setup) to add it to a wallet. ## S ### Sell wall The single-sided liquidity position that every Archr launch creates: the full coin supply, positioned from the launch tick upward, with no WETH on the buy side at deploy. Buyers eat into the wall to discover price. See [trading overview](/trade/overview#how-price-discovers). ### Slippage The maximum acceptable gap between the price you expected when you signed a swap and the price you actually got. The swap widget lets you set a tolerance in basis points; a fill outside tolerance reverts the swap rather than filling at a worse price. See [trading overview → slippage](/trade/overview#slippage). ### `SwapRouter02` Uniswap V3's canonical periphery router — the contract wallets and integrators call to execute swaps. On 4663 it lives at `0xCaf681a66D020601342297493863E78C959E5cb2`. The site's swap widget and every dev-buy call routes through it. See [Contracts → Uniswap V3 SwapRouter02](/network/contracts#uniswap-v3-swaprouter02). ## T ### Tick The unit of price granularity in a Uniswap V3 pool. Each tick is a fixed proportional step; the pool's price at a given tick is `1.0001^tick`. Archr pools use `tickSpacing = 200`, so valid ticks are multiples of 200. See the [Uniswap V3 docs](https://docs.uniswap.org/contracts/v3/reference/core/libraries/TickMath) for the math. ## W ### WETH Wrapped ETH on 4663, at `0x0Bd7D308f8E1639FAb988df18A8011f41EAcAD73`. Every Archr pool pairs a coin against WETH; the site's swap widget wraps and unwraps for you.
