Archr is a token launchpad on Robinhood Chain (chainId 4663). A single transaction deploys a plain fixed-supply ERC-20, creates a Uniswap V4 pool for it paired against native ETH, and places 95% of the supply into the pool as a single-sided sell wall. The remaining 5% is escrowed on-chain in the same transaction and pays out to ARCHR holders and the coin’s early buyers on a fixed schedule; the amounts and unlock times are enforced by the contract. See holder rewards. The launch-wall LP position is minted directly to the burn address, so it is owned by no one and no address (the platform included) can ever withdraw or move it. The pool’s own LP fee is 0; a hook on the pool skims 1% of the ETH side of every trade to the coin’s creator, paid as pure ETH. See risks → liquidity is burned, rewards are ETH. 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 V4 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 pairs the coin against native ETH at an LP fee of 0, and the pool’s hook skims 1% of the ETH side of every buy and sell; 100% of that skim goes to the coin’s recorded creator as ETH. See creator fees. The escrowed 5% pays ARCHR holders and the coin’s early buyers in time-locked tranches (amounts and times enforced by the contract; recipient lists computed off-chain by the platform from published snapshot blocks). See holder rewards. Coins launched before the current program keep their original behavior: they trade on a Uniswap V3 pool and their fees stay in the legacy ARCHR fee-flywheel.

  • Launchers (X): Your first launch from X. Mention the bot with !deploy SYMBOL to trigger from a tweet.
  • Launchers (fees): Creator fees. Every coin routes 1% of its trading volume to its recorded creator as ETH; Reddit and X launchers claim theirs with !claim.
  • Traders: Trading overview. How the V4 pool prices out and where to swap.
  • ARCHR holders: Holder rewards. How holding ARCHR through each coin’s launch earns a pro-rata slice of its escrowed 5%.
  • Risks: Risk disclosure. Chain, liquidity, and program risks before you launch or trade.
  • Support and private disclosure: X (@archrdeploy). The public channel; message the account for a private line to report a bug or vulnerability.

Contracts

Every new launch runs through the platform’s publicly verified contracts on Robinhood Chain: the launch factory that deploys the coin and burns the launch-wall LP, the pool hook that skims the 1% ETH creator reward, the site’s launchpad adapter in front of the factory, and the escrow contract that holds each coin’s 5%. Coins launched before the current program stay on the earlier factories, which remain deployed and keep custody of those coins’ locked LPs. All are verified on Blockscout. See Contracts for the full address list and the canonical Uniswap V4, Uniswap V3, Chainlink, and WETH addresses on 4663.
