Company profile
researched Aug 2026Ethos (Ethos Wallet) developed a digital asset wallet for the Sui layer 1 blockchain, positioned as a place for users to store crypto assets and to discover and interact with decentralized applications rather than as storage alone. The consumer product was available as a Chrome extension and a browser-based full-screen wallet explorer, with a mobile application planned. The company was co-founded by Nadia Eldeib (CEO) and Jared Cosulich (CTO), and was the first application live on the Sui developer network.
Alongside the wallet, Ethos shipped developer infrastructure for teams building on Sui: api.ethoswallet.xyz, a RESTful API for creating wallets with an API call and signing transactions with them from mobile, Unity or the web; and Ethos Connect, a drop-in "Connect Wallet" component for web dApps that works with Sui wallets and lets walletless users connect via email login. Ethos also built on-chain games, including Sui 8192 — described as the first fully on-chain game on the Sui developer network — plus on-chain chess and checkers, all playable inside the Ethos wallet explorer as interactive, dynamic NFTs.
In September 2024 Ethos announced it would shut down its Sui products, including the wallet extension and mobile app, Ethos Connect and the developer API, on 1 November, telling users to migrate to other wallets and, in the case of zkLogin accounts, to transfer their assets out. The team reported it was building a software simulator called CodeYam intended to make it faster to understand, test and demonstrate code changes in software applications.
Founding story
Ethos was co-founded by Nadia Eldeib (CEO) and Jared Cosulich (CTO) on the principle of providing an easy-to-use and secure wallet that would let users not only store and trade crypto but also discover and experience applications on the Sui blockchain.
Business model
Ethos offered a consumer self-custody wallet for Sui together with developer-facing infrastructure (a wallet-creation and transaction-signing REST API and the Ethos Connect wallet-connection kit), plus on-chain games used to drive discovery and usage of the wallet.
Traction
Sui 8192, the company's on-chain game, became one of the most popular applications on the Sui developer network with an average of over 100,000 transactions per day as of January 2023.
Latest developments
In September 2024 Ethos said it would cease operating all of its Sui products — the wallet extension and mobile app, Ethos Connect and the developer API — on 1 November 2024, and that it was building CodeYam, a software simulator for understanding, testing and demonstrating code changes.

Market position
Ethos described itself as the first experiential digital asset wallet on Sui and was the first application live on the Sui developer network; Mysten Labs partnered with it as wallet infrastructure for the Sui ecosystem. Following the 2024 shutdown, users were directed to alternatives such as the Mysten Labs-built Sui Wallet.
Technology
The products were built on the Sui layer 1 blockchain and the Sui Move smart contract language. Ethos supported batch transaction pre-approval in its Chrome extension for faster gameplay, described as a Sui-specific capability, and supported zkLogin-based accounts. Its games, such as Sui 8192, recorded every move on-chain and were themselves NFTs.
Go-to-market
Ethos distributed its wallet through a Chrome extension and web explorer with sign-up at ethoswallet.xyz, published developer documentation and a starter app at ethoswallet.xyz/dev, and used popular on-chain games as an acquisition channel. A strategic partnership with Mysten Labs, the original contributor to Sui, was announced in May 2023 to expand access for developers and end users.
End users of the Sui ecosystem seeking to store digital assets and use dApps, and developers building web, mobile and Unity-based applications on Sui who needed wallet creation, transaction signing and wallet-connection tooling.
Risks & controversies
