Deploy Uniswap V3 on Scroll: A Step-by-Step Guide

TLDR:

• Learn how to deploy the full Uniswap v3 suite on Scroll Sepolia Testnet in minutes
• Set up the v3 deploy repository, configure a Scroll RPC endpoint, and specify WETH/admin settings
• Understand core Uniswap v3 contracts (Router, Factory, NFT positions) and their AMM composition
• Leverage Scroll's hierarchical ZKP optimizations for efficient deployment

Introduction to Scroll Network

Scroll is an Ethereum scaling solution using zero-knowledge proofs for fast, secure, and affordable transactions. Its EVM compatibility allows seamless DApp migration. With Chainstack's support for Scroll Sepolia Testnet, developers can now deploy Uniswap v3 more easily than ever.

👉 Explore Scroll's hierarchical ZKP system for faster finality and lower fees compared to other L2 solutions.

Prerequisites

• Chainstack account for node deployment
• Node.js (JavaScript framework)
• Yarn package manager
• TypeScript V4.2.3

Deployment Overview

1. Create public chain project
2. Join Scroll Sepolia Testnet
3. Obtain node endpoint
4. Fund wallet with testnet ETH
5. Deploy Uniswap v3 contracts

Step-by-Step Deployment

1. Setting Up Infrastructure

Create a Chainstack project and join the Scroll Sepolia Testnet. Note your node endpoint credentials.

2. Funding Your Wallet

1. Acquire Sepolia ETH from Chainstack Faucet
2. Bridge to Scroll Sepolia using Scroll Bridge

3. Deploying Uniswap v3

Use the official v3 deploy repository with these requirements:

• Deployment account private key (0x...)
• Chainstack Scroll Sepolia endpoint
• Admin contract owner address

Deployment Command Structure:

- pk: Private key
- j: JSON-RPC endpoint
- w9: WETH9 contract address
- ncl: Native currency label (ETH)
- o: Owner address
