Monolith (TKN) is the Ethereum-based decentralized finance platform formerly known as TokenCard. The project rebranded to Monolith in August 2019, a change announced alongside partnerships with MakerDAO and Digix that expanded the tokens usable on its debit card platform. The Monolith name was drawn from Arthur C. Clarke’s novel 2001: A Space Odyssey, alluding to “transcendence in the world economy through the introduction of Decentralized Finance,” according to the company. [1]

Design and History

The Monolith logo is available in multiple formats, including PNG, SVG, and a full vertical variant, as distributed through crypto logo repositories. [2] The mark is also catalogued under the former TokenCard name in some logo archives, reflecting the project’s rebrand history. [3]

The rebrand from TokenCard to Monolith was announced in August 2019, with CEO Mel Gelderman stating that the new name helped the company “achieve our mission of democratising finance and bringing the Token economy to everyone.” [1] The visual identity change accompanied this strategic repositioning from a card-focused product toward a broader decentralized finance platform.

Meaning and Symbolism

The Monolith name references the iconic black monolith from Arthur C. Clarke’s 2001: A Space Odyssey, symbolizing transcendence and transformation in the context of decentralized finance. [1] The logo’s abstract symbol, rendered in black, visually echoes the monolith concept from the source material, establishing a direct connection between the brand name and its visual mark.
