The Reddit trigger deploys the same on-chain shape as the site launch (a plain 1B-supply ERC-20 with a Uniswap V4 pool whose launch-wall LP is burned to the dead address), except the trigger is a Reddit reply instead of a wallet signature. A plain !deploy has no gas cost to the launcher. The launch is broadcast on your behalf, and the addresses come back as an in-thread reply.
To buy a share of your own coin’s supply in the launch transaction, append the and buy suffix, which spends from a wallet you link once at archr.win/signup, or use the site flow.

​
Command shape

Reply to any comment or post visible to u/Archer_Bot with one of:
  • SYMBOL is the ticker: short, alphanumeric, uppercase by convention.
  • name is optional; when omitted the coin’s name defaults to the symbol.
  • and buy 0.05e optionally adds a dev-buy paid from your linked wallet: an ETH amount with an e suffix, up to four decimals.
  • The command is case-sensitive on !deploy.
  • Only the first !deploy in a comment counts. One coin per comment; you can post multiple !deploy comments in the same thread and each one launches its own coin.

​
What the bot does

  1. Reads the trigger comment on Reddit.
  2. Sanitizes the name and symbol per the rules on launch → name and symbol rules.
  3. Prices the launch tick from the live Chainlink ETH/USD feed on Robinhood Chain (feeds older than the on-chain heartbeat cause the launch to fail-closed rather than proceed on a stale number).
  4. Calls the launch factory (see Contracts), which atomically deploys the ERC-20, creates the V4 pool, places 95% of the supply into it as a single-sided sell wall with the launch-wall LP burned to the dead address, and escrows the other 5% for holder rewards.
  5. Replies to your trigger comment with the coin address, pool address, and Blockscout links.

​
Dedupe

Each Reddit comment can trigger at most one launch. The launch factory enforces this on-chain: a duplicate !deploy on a comment that already produced a coin reverts AlreadyLaunched.

​
When a launch is rejected

The platform does not reply when a command cannot be launched. Common reasons a !deploy will not produce a coin:
  • The command failed to parse (missing SYMBOL, or characters outside the sanitizer rules).
  • The originating thread is older than the archive cutoff (Reddit locks very old threads).
  • Launches from Reddit and X may be paused for maintenance. Comments and mentions are still read, but no launches are broadcast until the pause lifts. Site launches are unaffected.
If your comment parses cleanly and the bot goes silent, the platform is likely paused for maintenance.

​
After the reply

The bot’s reply includes the coin’s Blockscout URL. Open it and verify:
  • The token contract shows a fixed supply of 1,000,000,000e18.
  • The V4 pool exists (LP fee 0, tickSpacing 200) and holds 95% of the supply as single-sided liquidity; the other 5% sits in the on-chain holder rewards escrow.
  • The launch-wall LP position is owned by the burn address 0x…dEaD. That is the “liquidity is burned” invariant.
The coin’s swap widget on archr.win/token/<address> works for coins launched from every trigger surface, including Reddit and X.

Claim your creator fees

A launch from Reddit starts with no recorded creator, because a Reddit account is not a wallet. To record one, reply in the same thread, from the same Reddit account that posted the !deploy:
The platform matches the claim to your !deploy and records that address as the coin’s creator on-chain. The write is one-shot (a set creator can never be changed) and public, so it ties your Reddit account to that wallet; check the address before you post. Until you claim, the skimmed ETH simply accrues in the coin’s vault and never expires. See creator fees for how collection works.
