# Contracts

> Archr contract addresses on Robinhood Chain (4663) — launchers, ARCHR token, distributor, and the canonical Uniswap V3 + Chainlink + WETH addresses on 4663.

## Deployment

Archr runs on Robinhood Chain mainnet (chainId 4663). Every launcher factory below is verified on Blockscout. The owner of each factory below is the deploy wallet `0x9008C9eE6eF776c06D4aAFb4a4bfCF13083680c6`.

## Archr launchers

### `WebFactory`

The launcher factory the archr.win site uses. Deploys [`Coin`](#coin) contracts, creates single-sided V3 pools, and holds every LP NFT permanently locked. Its `launcher` — the only address allowed to call `launch(...)` — is the [`ArchrLaunchpad`](#archrlaunchpad) adapter. Constants: `SUPPLY = 1e27`, `FEE = 10000`, `TICK_SPACING = 200`.

```

```

### `ArchrLaunchpad`

The public payable adapter for the site trigger. Stateless — no owner, no pause, no storage — and immutable in its wiring to [`WebFactory`](#webfactory). Three entry points: `launch(...)` for launches without a dev-buy, `launchWithBuy(...)` for launches with an [dev-buy](/launch/dev-buy), and `launchWithBuyFromPost(...)` for launches keyed to an external post identifier.

### `RedditFactory`

The launcher factory the Reddit `u/Archer_Bot` uses. Byte-similar to [`WebFactory`](#webfactory) — same constants, same locked-LP custody surface, same `Launched` event shape. The `launcher` is set at deploy time by the factory owner and is the only address permitted to call `launch(...)`. Deploys `RedditToken`, a rename of [`Coin`](#coin).

```

```

### `TwitterFactory`

The launcher factory the X (`@archrdeploy`) mention bot uses. Byte-identical to [`RedditFactory`](#redditfactory) with only the contract name changed. Same constants and same locked-LP guarantee.

```
0x8044644e4458B76ae0331D30D07d468b615A07bD

### `Coin`

The token template every launcher factory deploys via CREATE2. See [FAQ → what does a coin look like on-chain](/reference/faq#what-does-a-coin-look-like-on-chain) for the properties. The `RedditFactory` and `TwitterFactory` deploy byte-identical renames (`RedditToken`).

Coin addresses are per-launch (deterministic from launcher + salt + name + symbol). See [launch overview](/launch/overview) for how a launch is triggered on-chain.

### `ArchrLauncher`

The one-shot launcher used to deploy the ARCHR platform token itself. Separate from the coin factories above — it launches a single coin, then `launched` flips to `true` and the contract cannot launch again. Holds a permanently-locked 70% LP; the other 30% went to the deployer at launch.

## ARCHR

### ARCHR token

The Archr platform token — a plain ERC-20 with fixed supply `1,000,000,000e18`. See [FAQ](/reference/faq#what-does-a-coin-look-like-on-chain) for the properties. Holding ARCHR makes an address eligible for the [fee-flywheel airdrops](/earn/archr-flywheel).

### ARCHR WETH V3 pool

The Uniswap V3 pool ARCHR trades on. 1% fee tier, tickSpacing 200. Locked-LP NFT held by [`ArchrLauncher`](#archrlauncher). **This pool address is excluded from the flywheel's top-50 holder snapshot** — its ARCHR balance is unsold single-sided liquidity, not a real holder.

### ARCHR fee-flywheel distributor

The address the [fee-flywheel program](/earn/archr-flywheel) uses as its working balance. Collected fees land here, the WETH-leg swap happens from here, and the top-50 airdrop is sent from here. Every airdrop shows up as 50 outgoing transfers of the coin-of-the-cycle.
