A
Airdrop
The scheduled payout of the ARCHR fee-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.
ARCHR
The Archr platform token. Holding ARCHR is the sole eligibility condition for the fee-flywheel airdrops.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.C
Coin
A token launched through Archr. See Contracts → Coin and 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.
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.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.Distributor
The address the fee-flywheel program 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.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.
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 (fronted by the ArchrLaunchpad adapter for the site), RedditFactory, and 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 oftickSpacing = 200. Because coin is token1 in the pool and WETH is token0, the launch tick is positive. See launch overview → 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.
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.N
NPM
Uniswap V3’sNonfungiblePositionManager — 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.
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. See 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.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.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.
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 is1.0001^tick. Archr pools use tickSpacing = 200, so valid ticks are multiples of 200. See the Uniswap V3 docs for the math.
W
WETH
Wrapped ETH on 4663, at0x0Bd7D308f8E1639FAb988df18A8011f41EAcAD73. Every Archr pool pairs a coin against WETH; the site’s swap widget wraps and unwraps for you.
