Quick answers to the questions most people ask on the way in. Each answer links to the page that covers it in full.

​
What is Archr?

Archr is a self-serve token launchpad on Robinhood Chain (chainId 4663). Every launch deploys a plain fixed-supply ERC-20 and creates a Uniswap V3 pool for it, with 100% of the supply locked into the pool as single-sided liquidity. There is no bonding curve and no graduation event — trading is live the instant the launch transaction confirms. See Introduction for the framing and Launch overview for the on-chain shape.

​
How do I launch a coin?

Three ways, all producing the same on-chain result:

​
Is the liquidity really permanently locked?

Yes. The launcher factory holds the LP NFT and no address (owner included) can withdraw or move it. The only value that can ever leave the position is the 1% swap fees. See risks → liquidity is locked, revenue is fees.

​
What does a coin look like on-chain?

A plain, 10-line OpenZeppelin ERC-20 with fixed supply 1,000,000,000e18 (1 billion, 18 decimals). No tax, no transfer hooks, no owner controls on the token itself. See Coin.sol — every token deployed through Archr uses the same template.

​
What does the V3 pool look like?

Standard Uniswap V3: 1% fee tier (fee = 10000), tickSpacing 200, paired against the canonical 4663 WETH. Full supply added as single-sided liquidity at launch. See trading overview → where to swap for where to swap.

​
Can I buy some of my own coin in the launch transaction?

Only from the site launch flow. The launch form has an optional dev-buy field that adds a same-transaction swap; if the swap fails, the whole launch reverts and the coin is not deployed. Reddit and X triggers do not support dev-buys. See dev-buy.

​
What does it cost to launch?

Native ETH on 4663 for gas — on the order of 0.005–0.01 ETH per launch at typical gas prices. If you include a dev-buy, add the ETH you are spending on that buy. There is no separate platform fee at launch time. See launch overview.

​
Are name and symbol unique?

No. Two different launchers can each ship a PEPE. The unique identifier is always the contract address. See launch overview.

​
Is trading 24/7?

Yes. Every pool is a plain V3 pool on 4663 — there are no market hours or session boundaries. See trading overview.

​
What wallets are supported on the site?

Anything the wagmi wallet adapter supports — MetaMask, Rabby, WalletConnect. See wallet setup.

​
How does the ARCHR airdrop program work?

Every launched coin’s 1% swap fees are collected periodically, and the WETH leg is swapped into more of the same coin. Once a coin’s balance in the distributor reaches 1% of that coin’s supply (10,000,000 tokens against the 1B fixed supply), the top-50 ARCHR holders receive an airdrop of that stack pro-rata to their ARCHR balance. The cycle repeats for every 10M threshold each coin crosses. See ARCHR fee-flywheel for the full mechanic.

​
How do I become eligible for the airdrops?

Hold ARCHR. Eligibility is a snapshot of the top 50 ARCHR-balance holders at each airdrop’s trigger block. See ARCHR fee-flywheel → what counts as a holder.

​
What is ARCHR itself?

The Archr platform token — see ARCHR fee-flywheel and Contracts → ARCHR token.

​
Is Archr live on mainnet?

Yes. The three trigger surfaces — site, Reddit, X — all run against Robinhood Chain mainnet (chainId 4663). See Contracts for the launcher addresses and Introduction for how the surfaces fit together.

​
What happens if a launch fails halfway?

It cannot. Every launch is atomic: coin deploy, pool creation, LP mint, and (on the site) dev-buy all succeed together or the entire transaction reverts. There is no “coin deployed but pool creation failed” state; there is no “pool created but LP mint failed” state. See dev-buy for the invariant. The launch reverts fail-closed rather than proceeding on a stale price. This can briefly block new launches during a chain-level incident but does not affect trading on already-deployed pools. See risks → price and oracle risk.

​
Can launches be paused?

Reddit and X launches can be paused for maintenance — comments and mentions are still read, but no launches are broadcast until the pause lifts. Site launches and pool trading are unaffected. Maintenance windows are posted at @archrdeploy.

​
Where do I report bugs?

Non-security bugs: DM @archrdeploy on X. Security vulnerabilities: do not post publicly — see security for the private disclosure process.
