Polygon Labs spinout Miden, a zero-knowledge proof-based blockchain project focused on high scalability, raised a $25M seed led by a16z Crypto, 1kx, and Hack VC
A16z Crypto led a $25 million investment round into Miden, an independent blockchain project spun out of Polygon Labs.
Context & Ripple Effects
Miden’s financing extends Polygon Labs’ effort to center zero-knowledge technology: Polygon had already shifted development emphasis toward its ZK-powered CDK after ending contributions to Edge.
It also follows a broader pattern of Polygon-linked projects becoming standalone capital-raising vehicles, including Avail’s $27M seed round after its own spinout. The round matters because it gives Miden independent backing while retaining its origin in Polygon’s technical ecosystem.
First-order effects
- Miden gains $25M of seed capital and a syndicate led by a16z Crypto, 1kx, and Hack VC to pursue its scalability-focused zero-knowledge blockchain project as an independent company.
- Polygon Labs adds another funded alumni project to its ZK ecosystem, while Miden’s investors obtain an early position in a Polygon-originated infrastructure bet.
Second-order effects
- Miden will compete more directly for developers, integrations, and specialist talent with other ZK-proof infrastructure teams, including companies such as Succinct, which also raised major backing for ZK-proof technology.
- The funding validates the spinout route for blockchain infrastructure teams: projects can separate from a parent ecosystem while using outside capital to build distinct networks or products.
Third-order effects
- If Polygon continues to produce independently financed ZK projects, its role could evolve from a single scaling network into a broader source of specialized infrastructure companies.
- The pattern may concentrate influence over early ZK infrastructure among a relatively small group of crypto-focused venture firms, though technical adoption—not fundraising—will determine which projects endure.
The trend: This is one data point in the unbundling of blockchain scaling stacks into separately funded zero-knowledge infrastructure companies.
