Debate on L3 networks' impact to Ethereum ensues after Polygon CEO comments
Polygon CEO Marc Boiron thinks that L3s take away value from Ethereum.

Recent comments made by Polygon Labs CEO Marc Boiron have ignited a debate on the necessity and potential consequences of Layer 3 (L3) networks, arguing that they may divert value and security away from the Ethereum mainnet.
The growth of adoption and development for L3 networks like Orbs, Xai, zkSync Hyperchains, and Degen Chain, have attracted significant activity across a number platforms, prompting key figures in the crypto space such as Boiron to voice their opinion on the matter of Layer 3 networks.
“L3s exist only to take value away from Ethereum and onto the L2s on which the L3s are built,” Boiron .
Boiron argues further argued that if all L3s settled to one L2, Ethereum would capture little value, putting its security at risk.
The L3 debate has been brewing for some time now. In 2022, Ethereum co-founder Vitalik Buterin began the argument that the purpose of L3s were to provide a “customizable functionality” towards L2s, although not necessarily operating as extensible layers of the core functionality designed for L2s. To Buterin, a third layer on the blockchain ecosystem would only be practical if its function fundamentally differs to what L2s already serve.
However, not everyone agrees with Boiron’s assessment. Some respondents argued that L2 value is inherently tied to Ethereum’s value, while others pointed out the potential benefits of L3s, such as lower bridging costs and specialized functionality.
Peter Haymond, senior partnership manager at Offchain Labs, countered Boiron’s claims. According to Haymond, advantages such as low-cost native bridging from L2, custom gas tokens, and specialized state transition are functions that “take value” away from Ethereum.
Arbitrum Foundation researcher Patrick McCorry at Boiron’s take, suggesting that L3s could allow L2s to become settlement layers and ultimately rely on Ethereum as a “global ordering service [and] final judge of settlement.
Degen Chain, a recently launched L3 running on top of the Base L2 network, is one of the L3 networks that have gained a significant traction (and volume), with one anonymous trader as much as a $2 million profit over a $7,000 investment.
Degen Chain, notably, was built using Arbitrum Orbit, a new offering from the Arbitrum ecosystem that enables developers to create “modular” or customizable Layer 2 and Layer 3 chains. In this context, Orbit chains operate by connecting to the core ecosystem of Arbitrum, with the ability to settle transactions over Ethereum L2 solutions.
