# Doppler Multicurve Goes Live on Base Sepolia *Build custom token launches with Doppler's newest market structure & TypeScript SDK* By [The Sharpening Block](https://paragraph.com/@whetstone) · 2025-09-16 doppler, multicurve, launchpad --- [Whetstone Research](http://whetstone.cc), in collaboration with [Zora,](http://zora.co) published a whitepaper called "Multicurve" in April 2025. Today, we are excited to share that **_Doppler Multicurve is now deployed on Base Sepolia and ready for application integrations._** ![](https://storage.googleapis.com/papyrus_images/4efe25470ffdf9c0022db2b85faaf4e207aae8e5cf8992833d538159fa478dd5.png) Source: Doppler Multicurve Whitepaper “Financial markets are increasingly becoming internet native. One size-fits-all token launchpads and liquidity bootstrapping protocols have failed to meet the needs of token creators and their communities. Developers increasingly want onchain markets with application-specific customizations. We introduce Doppler Multicurve, a new primitive for onchain issuance that enables multiple price curves to be specified during an initial auction or liquidity bootstrapping phase, which can then be tailored to a specific use case or application’s needs. In doing so, developers have the expressivity necessary to reduce maximal extractable value (MEV), and enable more capital-efficient liquidity formation."   🔗 Read the [Doppler Multicurve Whitepaper](https://doppler.lol/multicurve.pdf) About Multicurve  ----------------- Over the past few months, the [Zora](https://zora.co) team has been leveraging a custom implementation of Doppler Multicurve to power their application’s novel content and creator markets. This technology easily enables the creation of customized trading markets for individual pieces of content (such as specific posts on Zora) as well as creator profiles (individual creators on the platform). These content markets have been seamlessly integrated across the Base ecosystem, including within [The Base App](https://join.base.app/). Today, we're thrilled to bring Multicurve support to the broader developer community, opening up the best onchain price discovery and liquidity bootstrapping mechanisms to new asset classes. Introducing the Doppler Multicurve "Initializer" ------------------------------------------------ The Doppler Protocol now includes a "Multicurve Initializer" smart contract that gives developers and coin creators more fine-tuned control over price curves during initial token auctions, using Uniswap v4. Once tokens reach their parameterized goals - such as bootstrapping a specific amount of liquidity - the proceeds can be seamlessly migrated from the Multicurve Initializer to different versions of Uniswap, building liquidity in the most widely integrated DEX. This new version of Doppler offers significant improvements over legacy onchain market structures and enables quicker iterations and market optimizations post-integration. Developer tools --------------- Doppler Multicurve is now supported within the official Doppler TypeScript SDKs. For integrators that are already utilizing the v4 SDK, [configuring multicurve](https://docs.doppler.lol/sdk/references/v4/examples#example-4-multicurve-token-launch) should be less than a 10 line change to your parameterization. For new integrations, [get started with the latest alpha SDK](https://docs.doppler.lol/sdk/references/new-alpha-sdk/get-started).  ![](https://storage.googleapis.com/papyrus_images/d6554bdd8fdf284048d0e7e7ee92601a84d7bd083e64e66d19b6b4c44781c578.png) 🚨 Open source [Indexer](https://github.com/whetstoneresearch/doppler-indexer) and [Demo Application](https://github.com/whetstoneresearch/doppler-demo-app) support for Doppler Multicurve is coming soon. Follow along on the [Whetstone Research GitHub](http://github.com/whetstoneresearch) or [Paragraph blog](https://paragraph.com/@whetstone) to get the latest updates.  Supported networks ------------------ Doppler Multicurve is now deployed to Base Sepolia for teams to begin integration and testing. Mainnet deployments are coming soon. [View the Doppler protocol smart contract addresses](https://docs.doppler.lol/resources/contract-addresses). About Doppler ------------- Doppler is a smart contract protocol developed by [Whetstone Research](http://whetstone.cc) to power custom token launches. It is used by industry leading applications like Zora, Paragraph, and Coop Records, enabling efficient application specific markets. Doppler is available on Base, Ink, and Unichain, with other Ethereum Virtual Machine (EVM) network deployments coming soon.  Acknowledgements ---------------- Multicurve was originally designed and developed in collaboration with [Zora](http://zora.co)’s protocol engineering team, including [Rohan Kulkarni](https://x.com/rohanexposed).
