Most storage demos exist to show that storage works. Eulonomys exists to show that permanent storage matters.
Built by the Autonomys community, Eulonomys is a web application for creating permanent, on-chain eulogies stored on the Autonomys Distributed Storage Network via Auto Drive. It is also the first application built against Pay with AI3, the permissionless payment flow that allows anyone holding AI3 to purchase storage credits directly, without going through the foundation or filling out a form.
The choice of use case was deliberate. A eulogy is not a financial instrument. It is the last public act of love a person performs for someone they have lost. When you write a eulogy on Eulonomys today, it is designed to be there permanently. No server to shut down, no company to go bankrupt. The words endure. That promise is only credible because the Autonomys Network enforces it at the protocol level, not the terms-of-service level.
Eulonomys is built on Next.js, deployed on Vercel, with Prisma and Neon Postgres handling metadata, moderation state, and search indexing. The storage layer is the Autonomys DSN, accessed via the Auto Drive SDK.
Every eulogy is content-addressed. Anyone can verify that what they read is exactly what was written, unchanged and uncensored, by fetching it directly from the Auto Drive files gateway.
Payment is handled through Pay with AI3. Each eulogy is an on-chain transaction, meaning your words become part of an immutable record that exists as long as the network does. The application calculates storage cost based on file size, prompts the user to complete the transaction with AI3, and proceeds with the upload once payment is confirmed.
Eulonomys ships with a community fund. Sponsors can contribute AI3 tokens to cover storage costs for users who cannot afford them. Preserving memory, as the site puts it directly, should be within reach for everyone.
There is also an optional LLM-powered writing assistant. It is not designed to write the eulogy for you. It is designed to help you find the words you already have but may be struggling to express in your time of grief.
The community guidelines are honest about what permanence actually means. Moderation can exclude content from the browse index, but it cannot remove anything from the chain. Once a eulogy is written to the Autonomys DSN, no one, including the Autonomys team, can alter or delete it. The site asks users to be certain before they publish.
Eulonomys is open source and lives in the Autonomys community GitHub. Every architectural decision in the codebase was made with one question in mind: what would a developer building their own application need? The payment flow, the Auto Drive SDK integration, the wallet interaction on Auto EVM, the platform/merchant pattern, the moderation system, and the community fund are all minimum viable implementations, documented clearly, and designed to be copied and extended.
The Autonomys Network built Auto Drive to ensure data could last permanently. Eulonomys is the first proof that what lasts can also be deeply human.
If you are building an application on top of Auto Drive and Pay with AI3, we encourage you to explore and reference Eulonomys.
