OneGate, the Neo N3 mobile wallet, has undergone its first major update in more than two years. Wallet v2 is now live on the Apple App Store and Google Play, adding support for the recently finalized NEP-20, NEP-21, and NEP-33 wallet standards, as well as support for 15 languages.
The wallet was originally created by Neo co-founder Erik Zhang. The release introduces a redesigned wallet experience, an improved wallet import flow, and a range of performance improvements and bug fixes.
Mnemonic phrase re-import required
Existing OneGate users will need to re-import their mnemonic phrase (the recovery seed used to restore wallet access) when moving to version 2.0.
The OneGate team has instructed users to back up their mnemonic phrase before upgrading and to verify that the backup is stored securely, warning that upgrading without a verified backup may result in loss of access to the wallet and its assets.
Three new NEP standards
A highlighted change in OneGate v2 is its adoption of three Neo N3 wallet standards finalized earlier this year, which together create a full authentication and integration stack for the ecosystem. The standards mean any dApp can now authenticate users and call wallet operations through OneGate using a common interface, rather than building wallet-specific integrations.
The foundation is NEP-20, which defines the cryptographic rules for off-chain, address-based authentication, creating a Challenge/Response protocol that lets users prove ownership of their Neo address without passwords or on-chain transactions. Building on that, NEP-21 provides a unified dAPI interface that dApp developers can code against once and have it work with any compliant wallet. Methods like authentication() for verifying a user’s address, contract invocation, and message signing are all standardized, eliminating the need for wallet-specific bindings.
The third standard, NEP-33, addresses how these interactions are initiated on mobile. It introduces the neoauth:// custom URI scheme, which allows a native application to hand off an authentication request to a wallet app installed on the same device, with the wallet returning the result via a dapp:// callback. This is relevant for OneGate as a mobile-first wallet, the neoauth:// handoff enables app-to-app authentication directly, without requiring a browser extension.
OneGate is the second Neo wallet to begin implementing these standards. NeoLine shipped NEP-21 support in its Chrome extension wallet earlier this month. OneGate’s implementation covers all three standards and represents the first mobile wallet to adopt the full stack.
Multilingual support
The expanded language coverage widens the wallet’s accessibility beyond its prior focus on English and Chinese, lowering the on-ramp for non-English-speaking users entering Neo N3 via a mobile-first wallet.
OneGate v2 ships with support for 15 languages: English, Dutch, French, German, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, Simplified Chinese, Spanish, Traditional Chinese, Turkish, and Vietnamese.
