In a rapidly evolving cryptocurrency landscape, a new initiative labeled by some as “Ethereum’s Tron killer” is seeking to fortify Ethereum’s legacy against a rising tide of institutional-led alternative Layer 1 networks. The importance of stablecoins has surged in prominence, being hailed as one of the essential use cases for cryptocurrency as institutions increasingly engage with this digital asset category.
Codex, the brainchild of founder Haonan Li, is determined to uphold Ethereum’s dominance as the primary platform for stablecoins. Currently, Ethereum leads the stablecoin market with a staggering $153 billion in market capitalization. In comparison, Tron follows with $81 billion, together accounting for over 81% of the total stablecoin market share. However, new contenders like Plasma, Stable, Arc, and Tempo are gearing up to challenge this status quo.
The Ethereum community has shown significant concern in response to the introduction of Tempo, a Layer 1 stablecoin blockchain developed by Stripe in collaboration with crypto investment firm Paradigm. Many within the community are expressing disappointment and frustration, particularly because Paradigm previously invested in Etherealize, an institutional initiative focused on Ethereum, only to turn around and develop a competing blockchain.
In a defensive response, Haonan Li took to social media platform X, publishing a pointed article claiming that these new stablecoin networks are “attempts to supplant and attack Ethereum.” He asserted his confidence in Ethereum and Codex, stating that they will ultimately prevail over these emerging rivals.
Li elaborated on the advantages Ethereum holds, particularly its stable history, consistent uptime, and abundant liquidity, which he believes make it the favored platform for Wall Street operations. He pointed out current limitations in stablecoin transactions, which are often hindered by traditional banking processes that utilize SWIFT, resulting in delays. Codex aims to streamline these flows, significantly reducing the time needed for fiat-to-stablecoin conversions to near-instantaneous levels.
Vitalik Buterin, Ethereum’s co-founder, echoed Li’s sentiments by sharing the article and expressing enthusiasm about Codex entering the space as a Layer 2 solution and considering synergies with Ethereum’s Layer 1 from the outset.
Codex emerged from stealth mode in April, announcing a successful $16 million funding round led by Dragonfly Capital, with backing from notable investors like Circle and Coinbase. This financial support is designed to bolster its capabilities as it navigates the competitive landscape of stablecoin development.
