Our verdict on Protonauts

Protonauts may interest collectors and onchain gamers who want a character NFT designed to reflect activity across multiple games. Its clearest strength is the combination of Base-stored character data and the idea of progression based on game history. The main caveat is that the documentation does not identify supported games, explain progression rules, or say how to obtain a character. Treat the interoperability as a project aim until those practical details are published, and check costs and contract information before engaging.

What is Protonauts?

Protonauts is a character NFT project built around Base and intended for use across onchain games. Its documentation says the NFT’s image and attributes are stored on Base, and that characters can evolve as activity from other games is recorded. The project does not explain how to obtain a Protonaut, which games are integrated, or how progression works.

How Protonauts works

Protonauts are character NFTs whose images and attributes the project says are stored on Base. This is intended to keep those character details onchain rather than dependent on an external server or image service.

The project describes the characters as passive: activity from other games is meant to contribute to a Protonaut’s levels. It does not explain how activity is read, which games are connected, or how level changes are determined, so the extent of the interoperability is difficult to assess from the published overview.

Base-stored NFT data

The project says each Protonaut’s image and attributes are stored on Base, rather than relying on an external image host.

Game-history progression

Pros and cons

What we like

The project identifies Base as the chain where Protonaut images and attributes are stored.
Its character-progression concept is designed to draw on activity across other games.

It does not list which games currently record activity or how game integrations work.
Progression rules, including how levels are calculated, are not explained.
The project does not publish contract details, audit information, or fees in the documentation.

Is Protonauts safe?

Protonauts says its character images and attributes are stored on Base, but that does not remove the risks associated with NFTs or smart contracts. The project does not publish audit information, contract details, or a custody explanation in its documentation. It also does not describe its team or regulatory status.
