Zama, a cryptography company building state-of-the-art FHE solutions for blockchain, has announced the acquisition of KKRT Labs, a zero-knowledge R&D company focused on scaling blockchains using Zero-Knowledge Proofs.
While the strategic acquisition marks a major milestone for Zamia, it also strengthens its technical depth in blockchain scalability and validity (ZK) rollups, while accelerating its ability to deliver high-performance confidentiality to all public blockchains.
While the move seeks to expand the Zama ecosystem, the firm considers KKRT Labs a perfect fit, as it brings deep expertise in designing high-performance, proof-of-concept architectures and modular rollup systems for Ethereum-equivalent environments.
While KKRT Labs is backed by investors such as Vitalik Buterin, Starkware, Lambda Class, and Stake Capital, KKRT Labs, also known as Kakarot, is recognized as one of the strongest ZK-rollup teams in the ecosystem, aiming to build the most scalable and efficient proving engine for Ethereum-compatible chains.
 
Following the partnership, Zama and KKRT Labs will accelerate scalability efforts across the Zama Protocol, aiming to process over 10,000 confidential transactions per second on public chains, including Ethereum, Solana, and others.
Furthermore, the new scale will enable critical financial applications on-chain, such as confidential stablecoin payments, confidential DeFi, and confidential on-chain asset management.
Speaking on the strategic acquisition, Rand Hindi, CEO at Zama, said;
“KKRT Labs has assembled one of the best ZK-rollup teams in the world…Together, we will scale faster and reach new levels of performance, bringing the Zama Protocol to tens of thousands of transactions per second.”
Apart from the technical alignment both companies share, Zama and KKRT Labs share a common philosophy, which represents a belief in open-source innovation, confidentiality-first infrastructure, and democratizing access to advanced cryptographic technology.
According to the announcement, both teams have been driven by the conviction that scalability and confidentiality are not trade-offs, but complementary building blocks for the next generation of decentralized systems.
Vitalik Buterin, co-founder of Ethereum and KKRT Labs investor, said: “Kakarot has played a significant role in advancing the state of cryptographic technologies in Ethereum, from their early pioneering work on ZK-EVMs to their work on client-side proving for privacy preservation. I look forward to seeing what the team’s talented researchers and developers will do next.”
Following its commitment to ensuring a seamless integration of KKRT Labs, Zama will ensure that KKRT’s key engineers, operations, and leadership will transition fully into its platform. Also, KKRT’s ongoing initiatives will be integrated into Zama’s broader product and engineering roadmap with minimal disruption.
Eli Ben Sasson, co-founder of ZCash and CEO of StarkWare, also commented on the development, saying;
“I’ve had the privilege of collaborating with the exceptional Kakarot team over the years and witnessing firsthand what they can build. They’ve achieved tremendous success by taking a simple PoC from some of our engineers three years ago and turning it into impressive technology. They have a deep understanding of what it takes to scale blockchains using advanced cryptography, and I’m thrilled to see them dedicating their expertise to scaling and privacy. I’m sure they will provide pivotal support to Zama’s ambitious scaling roadmap.”
Clément Walter, co-founder, KKRT Labs, also added saying;
“Joining Zama allows us to bring our expertise towards scaling one of the last major challenges in blockchain: confidentiality…We’ve always believed scalability and confidentiality are essential to the adoption of blockchains, and by joining forces with Zama we can finally make high-throughput, low latency confidential on-chain finance a reality.”
