Helius acquires Light Protocol to build a programmable privacy layer on Solana, targeting encrypted payments, balances, and markets.
Helius has announced the acquisition of Light Protocol, a Solana-focused privacy and infrastructure company. Light Protocol authored Solana’s original zero-knowledge syscalls and built ZK Compression, which cuts onchain state costs by up to 1,000x.
The deal brings Light’s engineering team fully under the Helius umbrella.
Together, the two aim to build a programmable privacy layer directly on Solana. According to the announcement, Helius describes privacy as “the final scaling frontier for blockchains.”

Light Protocol’s Role in Solana’s ZK Infrastructure
Light Protocol has spent four years building privacy and scaling tools native to Solana. When its founders started, programmable privacy on Solana was not technically possible. The runtime simply lacked the primitives.
So the team built them from scratch. Light contributed the sol_poseidon hash function syscall, along with the sol_alt_bn128_group_op and sol_alt_bn128_compression syscalls to the SVM. These cover altbn G1 pairings, additions, multiplications, and G1/G2 compression.
Every zero-knowledge application on Solana today runs on or draws from that foundational work.
After shipping the ZK syscalls, Light turned to Solana’s account state problem. The result was ZK Compression, reducing onchain state costs by up to 1,000x. That tool addressed a persistent bottleneck for developers building at scale on Solana.

What the Acquisition Means for Solana Privacy
With the ZK syscalls and state compression shipped, Light had been circling back to its original goal: solving privacy on Solana at scale. The Helius acquisition accelerates that path significantly.
Light’s engineers now join Helius directly. Besides, the announcement states that Helius will bring its infrastructure, institutional relationships, and distribution to support the buildout. The target is a fully onchain, programmable privacy layer for the network.
The scope covers encrypted balances, encrypted payments, and encrypted markets.
Helius says this will come with auditability, configurability, and selective disclosure features. Those are capabilities that both institutions and early-stage startups typically require before engaging with onchain financial infrastructure.
Privacy as the Next Chapter for Solana Scaling
Helius framed the acquisition within a broader narrative about blockchain progression.
The announcement drew a line from Bitcoin proving cryptographic money was possible, to Ethereum proving it could be programmable, to Solana proving it could scale broadly. The next step, in Helius’s view, is proving that crypto at scale can also be private.
For the public, permissionless blockchains to meaningfully compete with legacy financial networks in trading, payments, and tokenization, Helius argues privacy is not optional.
The acquisition positions the combined team to address that gap directly on Solana, using the infrastructure Light has already spent years building. No financial terms of the acquisition were disclosed in the release.
