# PepuSwap Addresses

PepuSwap is PEPU's main DEX, operated by a third party (0sum.io): a white-labelled Uniswap V3 fork. Several of its contracts sit at non-canonical addresses, and two of them (a multicall and a Permit2) are easy to mistake for general infrastructure. This page lists them and the do-not-substitute rules.

Addresses are in the SDK's PepuSwap registry (`getPepuSwapContract`, `listPepuSwapContracts`). These are third-party contracts: PEPU does not operate them and they are outside this repository's security policy. `live-check` covers `pepuContracts` only, so confirm a contract with `pepu_check_contract_deployed` before relying on it. Mainnet only.

## Address table

Tokens it trades (also in `@pepu-chain/sdk` tokens): WPEPU `0xF9Cf4A16d26979b929Be7176bAc4e7084975FCB8` (18 decimals), USDT `0x06f69A40C33C5A4Cd038BBE1DA689D4D636Ec448` (6 decimals), USDC `0x20fB684Bfc1aBAaD3AceC5712f2Aa30bd494dF74` (6), WETH `0x7CCC51754216C04D4Bb1210630cCA16e5430Aa70` (18). Get PepuSwap's token list from `https://raw.githubusercontent.com/0sum-io/tokens/refs/heads/main/pepu-mainnet2.json` rather than hardcoding more.

## Do-not-substitute table

| If you want                                  | Use                                                                                                 | Never use                                                                                                                      |
| -------------------------------------------- | --------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| Batched reads (Multicall3 `aggregate3`)      | `0x9CE19273Ae9c24437DFF512E8DFCAed4E4B001bd` ([Multicall3](/contracts-and-addresses/multicall3.md)) | PepuSwap's `0x927a…383B` (a Multicall2-style contract with a different function set), and not `0xcA11…CA11`, which has no code |
| Permit2 for your own contracts and libraries | `0x000000000022D473030F116dDEE9F6B43aC78BA3` ([Permit2](/contracts-and-addresses/permit2.md))       | PepuSwap's `0xB461…8b4B`                                                                                                       |
| Integrating with PepuSwap's UI or routers    | PepuSwap's own addresses above                                                                      | The canonical Permit2 (its frontend overrides `PERMIT2_ADDRESS` for chain 97741)                                               |

The two Permit2 deployments respond to `DOMAIN_SEPARATOR()` with different values, so signatures are not interchangeable. The SDK ships separate ABIs (`pepuSwapMulticallAbi`, `pepuSwapPermit2Abi`) so the confusion is visible in types.

## Using the registry

```ts
import { getPepuSwapContract, listPepuSwapContracts } from "@pepu-chain/sdk";

const router = getPepuSwapContract(97741, "swapRouter02");
const all = listPepuSwapContracts(97741);
```

Other PepuSwap ABIs shipped: router, quoter, position manager, V3 factory, V3 pool, tick lens and universal router.

## Common failures

| Symptom                                                     | Cause                           | Fix                                    |
| ----------------------------------------------------------- | ------------------------------- | -------------------------------------- |
| Batched calls to `0x927a…` revert or return the wrong shape | It is not Multicall3            | Use PEPU's Multicall3                  |
| Permit2 signature rejected by PepuSwap                      | Signed for the canonical domain | Sign against PepuSwap's Permit2 domain |
| Quoter call spends gas                                      | Sent as a transaction           | Use `eth_call` or `simulateContract`   |

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.pepeunchained.com/contracts-and-addresses/pepuswap.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
