Mantle’s Biggest Bets As An Ethereum L2

Mantle’s Biggest Bets As An Ethereum L2

The implications for plans with a $500M ETH treasury, DeFi bank, and Bybit to scale crypto adoption

September 12, 2025

Mantle has been quietly building one of the most ambitious full-stack ecosystems in DeFi.

With a long-standing $500M ETH treasury in place long before the rise of ETH strategic reserves, a growing neobank product (UR) for everyday spending, and a newly announced partnership with Bybit to supercharge onchain access to Mantle, Mantle is positioning itself to become a major on-ramp for global DeFi users.

In this episode of The Edge Podcast, we sit down with Timothy Chen (Global Head of Strategy) and YZ (Product Lead) from Mantle to break down their biggest bets to grow Mantle. We unpack why Mantle leaned into building an Ethereum L2 earlier than most and why they believe ETH is the ultimate productive asset, plus how Mantle’s DAO and ETH treasury strategy sets them apart from both competitors and traditional finance. We also discuss a number of products incubated by Mantle such as Mantle Index Four (MI4) offering investors diversified exposure with yield.
