Real World Use Cases

LottoPGF Integrations in the Wild

Featuring on Zuzalu's Software Roadmap, this bespoke integration is set to launch as in-platform 'Zapp' for ZuVillages in Q3 of 2024. Capital formation tooling at the touch of a button!

LottoPGF's flagship free-to-play lottery drew in over 16k unique players who claimed more than 40k tickets between them. The latest round raised enough to be a co-sponsor of a Giveth QF round in just 3 days through optional donations.

The first project to independently deploy LottoPGF's integration, Onchain Lotería, together with their community of degen-regen playoors, is raising funds for educational initiatives across Latin America. is combining innovative reputation functionality with matching, Quadratic Funding, and LottoPGF integrations to create a holistic capital-forming, resource-allocating Public Goods Funding framework.

Student Debt Relief

LottoPGF's verifiable, open-source protocol is bringing web3 to a broader audience! This collaboration with a non-profit in the US (launching soon) promises to help relieve graduates of crushing college debt.

Lotteries 🤝 Ethereum


Anyone can start a lottery and configure it their own way, incentivising communities to effortlessly support causes they care about.


From randomness through winning odds, to fund distribution – everything is verifiable and auditable onchain.


Our lottery factories are deployed on Ethereum L2s, meaning they are safeguarded by Ethereum's robust and secure blockchain technology.


We remove financial intermediaries using smart contracts on Ethereum based blockchains. Funds are managed securely and decentralized, without relying on third parties for custody or distribution.

Truly random

We use sources of onchain randomness that are decentralised, publicly-verifiable, unpredictable & unbiased.

We're all Otto

Out of the Pond

LottoPGF's permissionless integration makes onchain lotteries viable at scale for the first time through novel randomness technology. And it does so while flipping the script on degenerate-gambling-tech™, putting it to use as a capital formation mechanism for public goods funding.

The founding fathers of the United States may not have had access to blockchain technology. But they did stan lotteries. Benjamin Franklin proposed a lottery for funding military efforts during the War of Independence. And once independence had been won, they continued to leverage draws, with ticket sales funding major infrastructure projects, like roads, railroads or bridges, as well as schools and churches.

In this interview, Cathy, Daniela, and Nico discuss the importance of sustainability and rational resource allocation in web3 projects. They explore funding models, such as quadratic funding and lotteries, and the potential risks and challenges associated with them. They also touch on the integration of reputation protocols and the role of open source in community engagement. The conversation highlights the need for inclusive and transparent funding mechanisms that prioritize efforts and community involvement. The interview concludes with an announcement of a partnership between City and LottoPGF, showcasing the potential impact of collaboration in the web3 space.

As we progress through Q2 and beyond, we'll continue building on the LottoPGF lore while giving back to our community and the broader Public Goods Funding (PGF) ecosystem. With that intention in mind, we're excited to announce that we're also taking things to the next level… Enter: OttoDAO

Kevin Charm presents a novel method of raffling built on proven cryptographic primitives; that is infinitely scalable (ANY number of winners, yet CONSTANT gas cost). It is also free of modulo bias, unlike raffles based on Fisher-Yates.

🦦OtterTrack is a special track for existing projects with pre-existing code, looking for more exposure, stage presence, and direct feedback from our Otter Judges. During the hackathon, OtterTrack projects had to jazz up with a fresh new feature, earning them a shot at presenting their progress onstage on April 14th.

Ethereum is leading the renaissance of coordination mechanisms for voluntary public goods funding. However, we are still missing an important and millenary mechanism to coordinate people to fund public goods. And it's one that can be improved 100x by doing it the Ethereum way.

Nico es una de las personas que han logrado emprender el viaje Degen a Regen y viceversa, logrando crear un estado de equilibrio en la fuerza.

In this episode, Zeugh tells us about his experience working for both companies and DAOs, how bots can help build and maintain communities, and get his take on how DAOs have evolved over the last two years. He also gives us his advice for launching a DAO and how to build community, the DAO and coordination tooling that he's most excited about going forward, and his reflections on attending crypto conferences over the last couple of years.

In this podcast Nico tells us about his current work as a contributor of OttoDAO building LottoPGF and how his vision of uniting degens and regens brought to fruition another project called $REGEN
