The Reddit trigger deploys the same on-chain shape as the site launch (a plain 1B-supply ERC-20 with a permanently-locked Uniswap V3 pool), except the trigger is a Reddit reply instead of a wallet signature. There is no gas cost to the launcher from Reddit or X. The launch is broadcast on your behalf, and the addresses come back as an in-thread reply.
Reddit triggers do not support the dev-buy option. If you want to buy a share of your own coin’s supply in the launch transaction, use the site flow instead.

Command shape

Reply to any comment or post visible to u/Archer_Bot with one of: 
u/Archer_Bot !deploy SYMBOL
u/Archer_Bot !deploy SYMBOL name goes here
  • SYMBOL is the ticker: short, alphanumeric, uppercase by convention.
  • name is optional; when omitted the coin’s name defaults to the symbol.
  • 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 RedditFactory.launch(...) which atomically deploys the ERC-20, creates the V3 pool, and locks the full supply into it as a single-sided sell wall.
  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. RedditFactory 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 V3 pool exists (fee tier 1%, tickSpacing 200) and holds the entire supply as single-sided liquidity.
  • The LP NFT is held by the RedditFactory. That is the “liquidity is locked” invariant.
The coin’s swap widget on archr.win/token/<address> works for coins launched from every trigger surface, including Reddit and X.
