Proposal Summary
- The purpose of this post is to inform the community of the canonical deployment of Uniswap v2 and v3 on Soneium, facilitated by Uniswap Labs.
- All of the Uniswap v2, v3 contracts have already been deployed.
Overview:
This proposal advocates for the deployment of Uniswap on Soneium, an Ethereum L2 developed by Sony Block Solutions Labs (a joint venture between Sony Group Corporation and Startale Group). The proposal aims to provide general background information to gauge the community’s interest in the opportunity to deploy Uniswap V2, V3 on Soneium.
This deployment proposal is an opportunity to tap into a consumer-focused Ethereum L2 and utilize Sony’s IPs, distribution channels, and access to real-world consumers. Built on the Superchain like Unichain, Soneium offers a scalable, low-cost, and highly interoperable infrastructure for DeFi protocols. The deployment would integrate Uniswap into an Ethereum L2 designed for mainstream adoption, potentially tapping into Sony’s user base and an upcoming dynamic ecosystem of DeFi, gaming, NFTs, RWAs, and entertainment applications.
About:
“Empowering individuals and communities to collaborate, create, and fill the world with emotion together.”
Sony Block Solution Labs believes that the development of a comprehensive Web3 solution based on blockchain technology has big potential for the company, which has developed a wide variety of businesses as part of its purpose to “fill the world with emotion, through the power of creativity and technology”.
Soneium launched its mainnet on January 14, 2025, settled 60M+ on-chain transactions with 4M+ unique wallet addresses as shown on Blockscout, and achieved $120M+ total value secured according to L2Beat, within 8 weeks. Soneium has also launched the Soneium Spark Incubation Program, attracting over 1,700 builders and projects. The participating Sony Group Companies include Sony Group, Sony Music, Sony Pictures, Sony Innovation Fund, Inzone, and Sony Global Education. Please refer to here for the list of winners of the first Soneium Spark.
We see DeFi as the backbone of blockchain adoption and is built with a vibrant DeFi ecosystem that promises to be both innovative and robust, featuring a well-rounded mix of multichain and native protocols. Notable names include Stargate, Squid, Lido, Mellow, StakeStone, KelpDAO, Solv, OpenEden, etc. Our Soneium Spark program also incubated several standout projects that will be launching as native DeFi protocols on Soenium, bringing unique features and services to our users, including Sake Finance (Monolithic Lending), Untitled Bank (Modular Lending), SuperVol (On-chain Options), WaveX (Perpetuals), Macaron Finance (Leveraged Farming), etc.
In addition to the existing Web3 services, the Soneium team has been investigating how new services that collaborate with businesses within the Sony Group can be developed as Soneium-compatible apps. Specifically, we will explore protecting the rights of content created by creators, new mechanisms for distributing profits to support creators and fans, and opportunities for creators to be active across the digital and real worlds.
Furthermore, by utilizing Web3 services, such as the Japan-regulated crypto exchange operated by Sony Group’s S.BLOX Inc., and adding new value to the various businesses and utilizing IPs, we aim to create apps that can be used daily by people who have never had the opportunity to experience Web3, and to build a world where Web3 services permeate people’s daily lives.
Key Benefits of Deployment:
- Potential to tap into the existing users from the Sony ecosystem and further expand Uniswap user base with Soneium’s distribution networks and go mainstream together. Soneium settled 60M+ on-chain transactions with 4M+ unique wallet addresses and achieved $120M+ total value secured within 8 weeks after launch.
- Establish Uniswap’s position as the major DEX and early mover on Soneium and capture a rapidly growing market in the ecosystem with a focus on real-world adoption (e.g. JPY-USD carry trade on-chain to explore, etc.)
- We envision Soneium to be one of the most unique ecosystems in the crypto world that truly foster Web3 mainstream adoption utilising Sony’s distribution channels and business opportunities. We see Uniswap as an important and reliable partner to facilitate users’ demand in swapping and earning passive income.
- Integrate closely with Soneium’s rapidly growing ecosystem, including strategic integrations with native DeFi projects and serve the asset exchange demand for Consumer & Gaming applications in Japan.
- Operates in a high throughput, tps, and low gas fees environment based on the Superchain to provide a smooth UX and efficient lending experience. Soneium is also equipped with top-tier infrastructures including Chainlink, Pyth, RedStone, LayerZero, Axelar, Superbridge, Across, Hyperlane, Li.Fi, Jumper Exchange, The Graph, etc.
- Receive liquidity incentives for Uniswap liquidity providers in any upcoming ecosystem-wide liquidity incentive campaign on Soneium from now to the future and help Uniswap bootstrap liquidity on Soneium.
