Fiamma, a Bitcoin and ZK infrastructure company transforming Bitcoin into a dynamic and programmable asset, announced that it has secured an oversubscribed $4 million seed round investment led by Lightspeed Faction and L2IV. Additional participating investors include Astera Ventures, Contribution Capital, Sat Ventures, Chapter One, and FoundersHead. This investment also includes participation from key strategic investors in the Bitcoin infrastructure space, such as BOB (Build on Bitcoin), along with various angel investors such as the founders of Satlayer and Daedalus.

The company plans to use this investment to scale its operations, accelerate product development, and drive adoption of its foundational technologies; Fiamma Bridge, the first trust-minimized Bitcoin bridge, and Fiamma Layer, the first ZK verification layer on Bitcoin powered by BitVM2.

Yovela Luo, co-founder and CEO of Fiamma, said: “Bitcoin is one of the world’s most valuable assets, yet over 98% of it remains idle. At Fiamma, we’re activating this dormant asset, utilizing it in the most trustless and secure manner. This ushers in a Bitcoin renaissance, seamlessly weaving it into everyday life.”

As part of a broader ecosystem effort, Fiamma is working closely with strategic partners in the ZK and Bitcoin space. These collaborations will accelerate innovation and adoption while positioning Bitcoin as the backbone of the decentralized internet and financial systems. To celebrate this milestone, Fiamma is also launching The Mama Code testnet campaign, inviting users to engage with the Fiamma Bridge and explore its innovative capabilities. Early adopters can participate and earn rewards.
