Arculus, the secure self-custody digital asset platform developed by CompoSecure (NYSE: CMPO), has integrated the Yield.xyz API to bring native and liquid staking directly into its cold storage wallet experience. The integration enables Arculus users to earn staking rewards across more than a dozen leading blockchain networks while maintaining full control of their private keys through Arculus’ hardware-backed security model.
With this release, Arculus expands beyond simple storage and transactions to become a full-featured self-custody staking platform. Users can now access onchain yield opportunities across major ecosystems including Ethereum, Solana, Tron, Avalanche, and Cosmos, all through a single, unified interface inside the Arculus Wallet App.
Secure Self-Custody Meets Native Staking
Arculus is a hardware-based cold storage wallet platform built around a metal smart card form factor that eliminates the need for batteries, charging cables, or USB dongles. The Arculus Key Card works in tandem with the Arculus Wallet App using a proprietary 3-factor authentication system that combines biometric authentication, a private 6-digit PIN, and the Arculus metal Key Card.
This layered security model allows users to maintain full self-custody of their digital assets while enabling intuitive “tap-to-transact” functionality for everyday onchain activity. With the integration of Yield.xyz, Arculus extends this security-first design to staking and yield generation.
Native and Liquid Staking Across Leading Networks
The Yield.xyz integration allows Arculus users to participate in staking across a wide range of proof-of-stake networks without leaving the wallet interface or relying on third-party platforms. Supported opportunities include:
- Ethereum staking via preferred validators and liquid staking through Lido and Rocket Pool
- Avalanche liquid staking via Benqi
- Tron liquid staking via JustLend
- Native staking for Celestia, Cosmos, Osmosis, Sei, Injective, Cardano, Polygon, Coreum, and additional networks
Yield.xyz acts as the staking infrastructure layer behind Arculus, providing standardized access to validators, liquid staking protocols, and yield products across chains. This allows Arculus to offer consistent staking flows across ecosystems while maintaining full self-custody for users.
Simplifying Onchain Participation
Rather than forcing users to manage different staking workflows for each blockchain, the Yield.xyz API abstracts protocol complexity and routes staking actions through a single integration. The result is a streamlined staking experience that feels native inside the Arculus wallet.
Users can discover staking opportunities, delegate assets, mint liquid staking tokens, and track rewards, all while their private keys remain secured by Arculus’ cold storage architecture.
“Yield.xyz gives Arculus users seamless access to staking across multiple ecosystems, all while maintaining the security expectations that hardware-based solutions require,” said Dr. Adam Lowe, chief product officer at Arculus. “Expanding staking support reflects our commitment to meeting user demand for broader onchain participation without compromising on self-custody.”
Infrastructure Built for Scale and Security
Yield.xyz is the unified yield infrastructure layer used by leading wallets, exchanges, and fintech platforms to power staking and DeFi products directly inside their applications. The API aggregates thousands of yield opportunities across 75-plus blockchains and provides production-grade access to validators, liquid staking protocols, money markets, and vaults through a single integration.
“Arculus provides an important access point for users who want secure, self-custodial staking,” said Serafin Lion Engel, CEO of Yield.xyz. “By integrating Yield.xyz, Arculus can offer staking across major ecosystems through a single connection while preserving the hardware-backed security model that their users trust.”
Expanding the Arculus Platform
Arculus is consistently ranked as one of the most innovative cold storage wallets in the market. In 2022, ABI Research named Arculus the Top Innovator in the cold storage wallet industry, citing its layered security model, metal smart card design, and ease of use.
Developed by CompoSecure, a global leader in secure authentication and payment technologies, Arculus brings institutional-grade security to everyday crypto users. The platform is designed for both new users entering crypto and experienced participants managing diversified onchain portfolios.
With staking now live, Arculus continues its evolution from a secure storage solution into a full-featured self-custody platform for earning, transacting, and participating across Web3.
