Helius Acquires Light Protocol to Boost Solana Privacy

TLDR

• Helius buys Light Protocol to build stronger Solana privacy tools
• Light Protocol returns to its original zero knowledge privacy mission
• Helius targets private payments and private DeFi on Solana
• ZK Compression work gives Helius a base for privacy infrastructure
• Solana privacy push grows as crypto consolidation reshapes the sector

Helius has acquired Light Protocol to expand Solana privacy infrastructure and push zero-knowledge tools into payments and DeFi. The deal brings Light Protocol back to its early privacy mission after its later work on ZK Compression. It also gives Helius a stronger cryptography team as privacy becomes a larger priority across crypto.

Helius Moves to Strengthen Solana Privacy

Helius, the Solana infrastructure firm founded by Mert Mumtaz, acquired Light Protocol to advance privacy tools on Solana. The company plans to combine Light Protocol’s cryptography work with its own infrastructure and developer reach. As a result, the acquisition targets private payments and private DeFi applications on Solana.

Light Protocol began in 2021 with a focus on zero-knowledge privacy for Solana. The project later shifted toward ZK Compression, which Helius and Light Protocol helped develop. The framework launched in 2024 and focused on lowering Solana data storage costs.

ZK Compression uses zero-knowledge proofs to reduce the cost of storing data onchain. evelopers can build larger consumer and enterprise applications without facing the same storage burden. Helius now wants to extend that technical base toward privacy-focused infrastructure.

Light Protocol Returns to Its Original Mission

Light Protocol will now return to its initial goal of building privacy systems for Solana users. The acquisition pairs its cryptographic research with Helius’s distribution, infrastructure, and market access. The teams plan to build a ZK-based privacy protocol for Solana applications.

The new privacy infrastructure remains unnamed, according to the announcement. However, Helius described it as fully programmable and configurable for different user needs. This structure could support both retail products and institutional use cases.

Helius plans to open the privacy infrastructure to developers in the coming months. That rollout could allow builders to test private transfers, DeFi tools, and custom privacy features. In turn, Light Protocol could become a key part of Solana’s privacy layer.

Crypto Privacy Gains Fresh Momentum

The deal comes during a broader consolidation phase in the crypto sector. Venture capital funding has slowed, and several projects have reduced operations or shut down. Stronger infrastructure firms have used acquisitions to expand technical teams and product lines.

Privacy has also returned as a major theme across blockchain development. The Ethereum Foundation has funded several privacy projects, and Zcash has gained renewed attention. Mumtaz has publicly supported stronger privacy tools across Solana and crypto.

Mumtaz said crypto needs privacy to support wider blockchain use. He compared blockchain privacy to HTTPS, which helped secure internet commerce. He also argued that cryptographic currencies still underuse cryptography, and Helius now aims to change that.
