# Contract addresses

Everything Unstable does — launching, trading, fee collection — happens through the contracts on this page. They live on the **Stable mainnet** (chain ID `988`).

## Unstable contracts

| Name                 | Address                                      | Purpose                                                          |
| -------------------- | -------------------------------------------- | ---------------------------------------------------------------- |
| **UnstableFactory**  | `0x4865b8974C1a8309E8791443577E3385c80436FB` | Entry point for launches. Registry of every launched token.      |
| **UnstableLPLocker** | `0xbB027B8210E98a19d7B90929B8baA77Ec09F0f96` | Holds every launched token's LP NFT. Splits + routes fees 80/20. |

Every launched **UnstableToken** is a fresh contract deployed via `CREATE2` — its address is deterministic per `(deployer, nonce, name, symbol)`. See [Events & indexing](/on-chain-reference/events.md) for how to enumerate them.

## External dependencies

Unstable relies on the canonical Uniswap V3 deployment on Stable, plus a couple of infrastructure primitives:

| Name                              | Address                                      |
| --------------------------------- | -------------------------------------------- |
| USDT0 (ERC-20 side)               | `0x779Ded0c9e1022225f8E0630b35a9b54bE713736` |
| UniswapV3Factory                  | `0x88F0a512eF09175D456bc9547f914f48C013E4aA` |
| NonfungiblePositionManager (NFPM) | `0x3BdC3437405f7D801b6036532713fc1F179136a6` |
| SwapRouter02                      | `0x32eaf9B5d5F2CD7361c5012890C943D7de84C22a` |
| QuoterV2                          | `0xb070179E7032CdA868b53e6C1742F80c9e940d1A` |
| Universal Router                  | `0x5Be52b52f3d1dbC324d2959637471a4208626144` |
| Permit2                           | `0x000000000022D473030F116dDEE9F6B43aC78BA3` |
| Multicall3                        | `0xcA11bde05977b3631167028862bE2a173976CA11` |

## The launch configuration

Every launch uses the same immutable parameters — set on the factory at deployment and provable via `cast call`:

|                              |                                               |
| ---------------------------- | --------------------------------------------- |
| Total supply per launch      | 1,000,000,000 × 10¹⁸ (1B tokens, 18 decimals) |
| Pool fee tier                | 1% (10,000 bps)                               |
| Tick spacing                 | 200                                           |
| Anchor tick (token = token0) | -407,600                                      |
| Starting mcap                | \~$2,000 USDT0                                |
| Deploy fee                   | 2 USDT0 (2,000,000 in 6-decimal raw)          |
| Initial-buy cap              | 5% of supply (50,000,000 tokens)              |
| Fee split                    | 80% creator / 20% treasury (immutable BPS)    |

## Verification status

| Contract         | Verified?                                                                                       | Link                                                                                        |
| ---------------- | ----------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| UnstableFactory  | ✅ Verified via Etherscan V2 API                                                                 | [stablescan.xyz](https://stablescan.xyz/address/0x4865b8974C1a8309E8791443577E3385c80436FB) |
| UnstableToken    | Auto-matches the first verified launch (bytecode-identical per launch)                          | See any launched token on StableScan                                                        |
| UnstableLPLocker | Intentionally unverified during test phase — see [LP position lock](/under-the-hood/lp-lock.md) | —                                                                                           |

## RPC endpoints

| Network     | URL                                      |
| ----------- | ---------------------------------------- |
| Public HTTP | `https://rpc.stable.xyz`                 |
| Explorer    | [stablescan.xyz](https://stablescan.xyz) |

Private endpoints (Alchemy, dRPC, etc.) work identically — Stable is on the Etherscan V2 API and Alchemy's Stable mainnet list.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.unstable.run/on-chain-reference/contracts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
