OneGate, the Neo N3 mobile wallet, has received its first major update in over two years. Wallet v2 is now live on the Apple App Store and Google Play, with support for the recently finalized wallet standards NEP-20, NEP-21 and NEP-33, 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.
Donkey re-import required
Existing OneGate users will need to re-import their mnemonic (the recovery seed used to restore access to the wallet) when moving to version 2.0.
The OneGate team has instructed users to back up their mnemonic before upgrading and to verify that the backup is safely stored, warning that upgrading without a verified backup could result in loss of access to the wallet and its assets.
Three new NEP standards
A notable change in OneGate v2 is the adoption of three Neo N3 wallet standards finalized earlier this year, which together create a complete authentication and integration stack for the ecosystem. The standards mean that any dApp can now authenticate users and invoke wallet operations through OneGate using a common interface, rather than building wallet-specific integrations.
At its core is NEP-20, which defines the cryptographic rules for off-chain, address-based authentication, creating a Challenge/Response protocol that allows users to 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 make it work with any compatible wallet. Methods such as authentication() verifying a user’s address, invoking contracts, and signing messages 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 pass an authentication request to a wallet app installed on the same device, with the wallet returning the result via a dapp:// call back. This is relevant to OneGate as a mobile-first wallet, the neoauth:// handoff enables app-to-app authentication directly, without the need for a browser extension.
OneGate is the second Neo wallet to implement these standards. NeoLine delivered NEP-21 support in its Chrome extension wallet earlier this month. OneGate’s implementation includes all three standards and represents the first mobile wallet to use the full stack.
Multilingual support
The expanded language coverage expands the wallet’s accessibility beyond its previous focus on English and Chinese, lowering the barrier for non-English speaking users entering Neo N3 through a mobile-first wallet.
OneGate v2 comes with support for 15 languages: English, Dutch, French, German, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, Simplified Chinese, Spanish, Traditional Chinese, Turkish and Vietnamese.
