Entrepreneur Joel Dietz accused the blockchain software firm Consensys of taking the idea for a web-based cryptocurrency wallet that would eventually become MetaMask, CoinDesk reported, citing a lawsuit filed in state court in California on Tuesday.
Dietz claims he initially developed the intellectual property for an in-browser crypto wallet in a 2014 project called Vapor. For the project, Dietz recruited Consensys employee Aaron Davis for coding help in 2015, but Dietz asserts that Davis went off to found a browser-based crypto wallet called MetaMask with Dan Finlay.
Dietz also claims that Consensys downplayed his involvement in MetaMask after the wallet app launched.
Consensys refutes lawsuit
In a statement to CoinDesk, Consensys claimed Dietz “has no relation to MetaMask” and insisted that Aaron Davis and Dan Finlay co-founded MetaMask in 2016.
Consensys is considered a crypto ecosystem staple for its oversight of MetaMask, one of the most popular cryptocurrency wallets. The firm netted $450 million in Series D funding in early 2022, earning Consensys a $7 billion valuation.
