The deal brings Polygon’s cumulative zero-knowledge technology investment to over $1 billion, the company said. Toposware’s team is behind Polygon’s Type 1 Prover technology.
Polygon Labs has acquired blockchain research and engineering firm Toposware, marking its third investment in zero-knowledge (ZK) startups over the past three years.
Toposware has been collaborating with Polygon Labs to develop its Type 1 Prover, which allows Ethereum-compatible blockchains to adopt zero-knowledge proofs without needing major changes. With the acquisition, 11 engineers from Toposware will integrate with the existing ZK development teams on Polygon.
Polygon says the deal brings its cumulative investment in ZK technology to over $1 billion. In 2021, Polygon acquired two other companies working on Ethereum scalability and privacy, Mir and Hermez, for a combined $650 million through multiple transactions.
