Archr is a token launchpad on Robinhood Chain (chainId 4663). A single transaction deploys a plain fixed-supply ERC-20, creates a Uniswap V3 pool for it, and locks 100% of the supply into the pool as a single-sided sell wall against WETH. The LP position is permanently locked in the launcher contract, so no address (owner included) can withdraw or move the principal, and the only value that can ever leave is the 1% swap fees. See risks → liquidity is locked, revenue is fees. There are three ways to launch a coin, and the on-chain result is identical in each: connect a wallet at archr.win and use the launch form, reply u/Archer_Bot !deploy SYMBOL [name] to any Reddit thread the bot can see, or mention @archrdeploy !deploy SYMBOL [name] on X. The launch form additionally lets you buy a share of the supply for yourself in the same transaction. If that dev-buy swap reverts, the whole launch reverts and the coin is not deployed. See dev-buy for the invariant. Trading happens on the newly created V3 pool immediately. No bonding curve, no vesting, no graduation event. Prices discover as buyers eat through the single-sided sell wall placed at launch. The pool is a standard Uniswap V3 1% fee tier (fee = 10000, tickSpacing = 200). Every buy and sell contributes to the locked-LP fee bucket, which feeds the ARCHR fee-flywheel: once a launched coin’s accumulated fees have been recycled into 1% of its own supply (10,000,000 tokens against a 1B fixed supply), the top 50 ARCHR holders receive an airdrop of that stack pro-rata to their ARCHR balance.

Contracts

Every launch runs through one of three publicly verified launcher contracts on Robinhood Chain: the site’s ArchrLaunchpad, Reddit’s RedditFactory, and X’s TwitterFactory, plus the underlying WebFactory that the site adapter fronts. All are verified on Blockscout and share the same locked-LP, fees-only custody surface. See Contracts for the full address list and the canonical Uniswap V3, Chainlink, and WETH addresses on 4663.
