NULS is a blockchain protocol foundation launched in 2017, originally built around the vision of making blockchain simpler through a modular, microservices-based architecture. The project’s visual identity has undergone two documented rebranding efforts, first in 2021 and again in 2024, with a further shift toward an AI-focused identity in 2025.
Design and History
The NULS logo has long been described as resembling a modification of the infinity symbol (♾️), a design choice that the project has tied to its vision of limitless potential for growth, ceaseless research, and radical innovation. The mark was intended to symbolize the project’s “Ultima vision,” encompassing endless possibilities for the platform’s development. The name NULS itself derives from the programming term “NULL,” reflecting the team’s origin story of building from zero: “NULL” is nothing, while “NULS” represents everything the team wanted to create in the blockchain world.

In May 2021, NULS launched a new identity platform, which included a refinement of the logo. Patric Vogel, then VP of Brand Management for NULS, described the change as reflecting the project’s “recent heritage of innovation” and its forward-looking promise to developers building blockchain and DeFi applications on the platform. The rebrand also introduced the tagline “Making It Easier To Innovate.” [3]
In May 2024, NULS announced a comprehensive rebranding, including a new logo, updated visual identity, and redesigned website, intended to reflect the project’s updated vision and core values in the Web 3.0 era. [4]
By early 2025, the project had adopted the name NULS AI, positioning itself as “The Global AI Consumer Layer.” The network underwent a complete renewal with a new logo, new website, and a new roadmap focused on artificial intelligence. The logo shifted from the traditional lime green to a very light blue, while the website adopted a gradient color combination with a more modern look. [5] [6]
Meaning and Symbolism
The infinity-inspired form of the NULS logo has been the most consistent symbolic element across the brand’s iterations. The project has explicitly stated that the logo represents the infinite development space for NULS, encouraging continuous exploration and innovation without limits. [1]
Official brand guidelines from 2021 described the logo as “the key building block of our identity, the primary symbol you will see across platforms,” representing the team as “a group of bold and passionate people.” The guidelines also specified that the primary way to display the NULS logo was in color, ideally on a black background. [7]
Typography and Design
The 2021 brand guidelines documented a complete visual system for NULS, covering the name, logo, color, type, and graphics. The guidelines emphasized a “bold and bright design” intended to present a strong, unified image of the company, aligned with the brand’s core message of making blockchain simple and easy. [7]
Following the 2025 transition to NULS AI, brand color data reflects the shift away from the earlier green palette. The current brand color is recorded as a light blue tone (hex #61ACFF), consistent with the documented change from lime green to light blue. [8]
