How 375go Simplified Solana Mobile Onboarding with Para's Wallet-as-a-Service Platform

375go is the mobile gateway into 375ai’s decentralized data network on Solana. The app lets anyone contribute real-world data (like mapping network signal strength) and earn rewards in the form of the network’s own EAT, Edge AI Token, in return.

To onboard everyday users, the 375ai team knew the login process had to feel effortless – closer to a web2 sign-up than crypto UX. In this case study, we walk through how 375ai approached embedded onboarding early on, what they learned about where users dropped off, and why they ultimately moved to Para's wallet-as-a-service suite, leveraging the Swift SDK for a smooth, more intuitive experience.

Background on 375ai

375go is intentionally built for a broad audience beyond crypto natives. Many users don't already have a Phantom wallet and most shouldn't need to understand private keys to get started. That meant onboarding needed to be fast, familiar, and reliable from the first session.

Early on, the team used an in-app wallet and authentication setup (Magic) to reduce friction. But by November 2025, the team switched to Para after seeing stronger onboarding performance with a more seamless UX, a straightforward integration experience, and first-class iOS support for both developers and end users.

Unlocking Effortless Mobile Onboarding on Solana with Para

Instant Wallet Creation: Para's SDKs allows 375go users to sign up with their existing credentials (email/password, Google, Apple ID) and auto-create a Solana wallet in the background. The moment a user registers or logs in, a Para wallet is silently generated and linked to their account. This made onboarding feel as easy as creating an account on any standard app. 

Native Mobile UX Integration: Para offers 375go native mobile SDKs for iOS and Android (with support for Swift, Flutter, and React Native), which made the integration straightforward and allowed the team full control over the app’s UI/UX. The wallet creation and login flows were embedded directly into 375go’s interface, matching the app’s design with no webviews or external redirects. Para’s mobile approach leverages secure device storage and FaceID/TouchID authentication so that users get instant, biometric-secured access to their wallet. All these improvements mean that a new user can go from installing 375go to earning rewards within minutes, without confusion or any external setup.

Embedded Wallets: Our wallet-as-a-service platform is built with Distributed MPC and passkeys behind the scenes to secure each wallet’s private key without burdening the user with seed phrases. In practice, this means 375go users never see a seed phrase or have to manage any recovery codes for their wallet. The full private key is never exposed or assembled at once, yet whenever 375go needs to sign a Solana transaction, it can do so seamlessly via the Para SDK. From the user’s perspective, actions like claiming rewards or managing a node happen with a simple tap and confirmation, with no signing prompts interrupting UX.

Persistent Sessions and Multi-Device Support: Para’s session management keeps users securely logged in across app restarts. A 375go user who signs up once with Para can reopen the app days later and continue where they left off, with their wallet still ready to use. This persistence reduces friction for returning users, eliminating the need to re-authenticate on every new session.

Today, every new 375go user gets a ready-to-go Solana wallet secured by their device, with minimal effort on their part, and maximum trust in the product. That unlocks what 375ai actually cares about: more contributors, more real-world data, and a healthier decentralized network.
