Ethos Wallet, which integrates into decentralized applications (dapps) on the Sui blockchain, has raised $4.2 million in a seed funding round led by Boldstart ventures and gumi Cryptos Capital (gCC). The funds will be used for hiring, continued development of the wallet, developer infrastructure and to expand the product beyond traditional wallet capabilities, according to the press release.

Other investors in the round included Mysten Labs, Tribe Capital, Matrixport, Charge Ventures, Builder Capital, Alliance DAO, and Meltem Demirors, among others.

Co-founded by CEO Nadia Eldeib and CTO Jared Cosulich, Ethos Wallet was the first application to go live last year on the developer network of Sui, a layer 1 blockchain built by Mysten Labs, which is staffed by veterans of Meta’s scrapped Diem stablecoin project. The wallet can be used to store and trade crypto and to help discover and build dapps in the Sui ecosystem. The Ethos Wallet team has also launched the on-chain game Sui 8192 and chess and checkers games backed by non-fungible tokens (NFTs). The games can be played directly in the wallet.
