Tangem — Powering Mobile-First Multi-Chain Staking

Introduction

Tangem is a Swiss technology company that pioneered card-based hardware wallets for cryptocurrencies. Founded in 2017 and headquartered in Zug, Switzerland, the company's signature product is a credit-card-shaped device with an embedded secure chip that users tap to their smartphone's NFC area to sign transactions — enabling setup in under one minute without seed phrases or cables. Each Tangem Wallet set includes 2-3 cards providing redundant access to the same wallet. With EAL6+ security certification and support for thousands of tokens across major blockchains, Tangem has distributed over 4 million wallets in 170 countries. The company is backed by $23 million in funding including a $15 million investment from SBI Holdings.

As Tangem expanded from Solana into native staking for assets like ATOM, BNB, POL, DOT, SOL, TRX, and TON (with more on the roadmap), it needed a single, reliable staking backend that matched its minimalist, mobile‑first UX.

Yield.xyz powers Tangem’s native staking provider layer, turning complex, multi‑network staking into a consistent “tap‑to‑stake” experience inside the Tangem app.

Challenges

• Deliver fast, intuitive staking flows on small screens, while preserving Tangem’s tap‑to‑sign hardware model.
• Scale from single‑network to multi‑asset staking (SOL, TRX, ATOM, BNB, POL, TON, and DOT) without rebuilding integrations and validator logic for each chain.
• Maintain security and trust—including slashing and downtime protection—without adding friction for mainstream users.
• Keep the entire experience aligned with Tangem’s minimal, non‑custodial design and support flows.

Yield.xyz Solution

• Unified Staking Provider: Tangem integrates once with Yield.xyz as its native staking provider, rather than integrating multiple individual validator APIs.
• Multi‑Asset Coverage: Yield.xyz’s staking infrastructure supports Tangem’s rollout across SOL, ATOM, TRX, POL, BNB, DOT, TON and future networks, while handling validator selection, reward flows, and key‑safe smart contract interactions under the hood.
• Risk & Reliability Layer: Yield.xyz covers slashing losses and node downtime for Tangem staking through SLA’s with our preferred validator’s, so users benefit from institutional‑grade protections while still delegating from their own wallets.
• Tangem white-label Solana validator: Yield.xyz helped launch and configure a dedicated WL Solana validator which increased revenue generation while allowing for a fully branded experience.
• Mobile‑First UX Fit: The integration returns simple, ready‑to‑execute staking flows that Tangem renders as a clean “Stake / Native staking” journey, signed via card tap—no browser extensions or external dApps required for native staking.

Results & Impact

• Tangem users can natively stake multiple leading PoS assets — SOL, TRX, ATOM, BNB, POL, TON, DOT — from the same wallet they already use to store their assets.
• Staking is now a core, everyday feature: a consistent tap‑and‑stake flow that works for beginners while still satisfying power users who want non‑custodial control and competitive yields.
• Tangem strengthens its position as a mobile‑first hardware wallet with built‑in yield, while Yield.xyz quietly absorbs the complexity of validators, networks, and yield interactions in the background.
