What Is Cypherock Wallet?

Cypherock is a hardware wallet maker that has created a decentralised crypto cold wallet for secure self-custody of digital assets. The flagship product, Cypherock X1, splits the private key into 5 cryptographic shards using Shamir’s Secret Sharing.

The shards live across 5 tamper-resistant components: 1 X1 Vault device and 4 X1 Cards. To sign a transaction, the user taps any 1 of the 4 cards onto the vault.

Cypherock reports being audited by Keylabs, verified reproducible by WalletScrutiny and is listed on bitcoin.org.

The X1 Cards use NFC smartcards with EAL 6+ secure elements, the same hardware grade as bank credit cards. The X1 Vault runs a dual-chip architecture for offline computation and verification.

Key specifications of Cypherock X1:

• Coverage of 18,000+ digital assets including BTC, ETH, SOL, and POL.
• Up to 4 independent wallets stored inside one device.
• Compatibility with BIP39 wallets like Ledger, Trezor, MetaMask, and Trust Wallet.
• Connection to dApps through WalletConnect.
• Cypherock Cover, a non-custodial inheritance service launched in Q4 2024.

Why Choose Everstake as the Infrastructure Layer

Everstake has run validator infrastructure across 130+ networks historically and currently supports 30+ active networks, with $7B+ staked to date. The company has served 1.6M delegators through 40,000+ validator nodes.

Compliance matters for embedded products. Everstake is certified under SOC2, ISO27001, and GDPR compliant, with a multi-year slashing-free history on major networks.

Operational footprint covers 10+ countries and 420+ servers. Custodian partners include BitGo, Anchorage Digital, Copper, and Zodia Custody.

Staking Through the Everstake Wallet SDK

Staking is the first part of this integration. Cypherock X1 users can now delegate major proof-of-stake assets directly from cySync, with rewards accruing on-chain and keys never leaving the hardware device.

Everstake is the exclusive staking provider for CypheRock.

The integration uses the Everstake Wallet SDK, which exposes a unified interface for delegation, claiming, and unstaking across supported networks.

Staking through cySync is non-custodial. Users keep ownership of their assets at all times, and Everstake’s validator nodes act only as the delegation target. 

The staking steps inside the cySync app:  

1. The user selects an asset.
2. Signs the delegation on the X1 Vault with NFC confirmation from any 1 of the 4 X1 Cards. 
3. The transaction broadcasts to the network.
4. Rewards become claimable according to each network’s native schedule.

The Everstake High Yield Stablecoin Vault

The partner-managed Everstake High Yield Stablecoin Vault is a decentralized product built for users seeking risk-managed liquidity farming strategies on their stable assets. 

Through this integration, Cypherock gives its users direct access to institutional-grade asset strategies on USDC (Ethereum, Base) and USDT (Ethereum).

Key features include:

• Optimized Rewards: Curated liquidity farming strategies delivering 7%–12% APY on USDC.
• Decentralized Structure: Fully on-chain execution via permissionless smart contracts, with users retaining complete control of their assets.
• Rigorous Risk Management: Dedicated Risk Manager oversight, audited execution, and predefined safety parameters backed by continuous monitoring.
• Full On-Chain Transparency: Powered by Everstake’s enterprise-grade validator infrastructure.

Inside cySync, deposits and redemptions are signed on the X1 Vault device. 

The vault mints share tokens to the user’s wallet on deposit and burns them on redemption, returning the underlying USDC or USDT in a single on-chain transaction with 0.5% fee for instant redemption and 0% for standard queue (~3 days).

The Everstake USDC Prime Solana Vault

The Everstake USDC Prime Solana Vault is an embedded DeFi product designed to deliver institutional USDC yield on Solana. It is delivered as a white-label SDK built on top of Kamino Finance.

The vault is non-custodial. Depositors hold vault share tokens, and operators cannot move user funds. 

The strategy is curated by Gauntlet, an on-chain institutional solutions curator, with Everstake providing the SDK and integration layer.

The product targets idle USDC (on Solana) balances sitting inside wallets. Instead of holding inactive USDC, Cypherock users can route it into a curated Kamino position and redeem instantly with a 20% fee on rewards.

The roles are clear: 

• Everstake runs infrastructure and the SDK, 
• Gauntlet sets and monitors strategy parameters
• Kamino is the underlying execution venue
• Cypherock is the hardware-secured signing surface. 

The strategy is deposit-only and operates without leverage, so there is no liquidation exposure for depositors.

Deposit and redemption flows mirror those of the High Yield Stablecoin Vault. 

1. The user signs an atomic transaction on the X1 Vault, 
2. The Everstake SDK routes it to the Solana vault
3. Share tokens are minted or burned accordingly. 
4. Redemption settles at T+0 under normal conditions, subject to Kamino vault utilization.

Why Cypherock Partnership Makes Sense

Cypherock X1 has a security model that aligns with non-custodial staking-related products. The wallet shards keys across 5 components, potentially removing the single point of failure that exists with seed-phrase-based wallets.

Cypherock X1 owners  are looking for hardware-secured access to on-chain strategies, not custodial alternatives.

The cySync application supports WalletConnect and 18,000+ assets, which makes adding staking flows and vault flows a natural extension of how Cypherock users already manage portfolios.

What Comes Next

Everstake is opening the Wallet SDK and both vault SDKs to additional card issuers, wallet providers, and treasury desks.

The roadmap focuses on widening distribution while keeping the validator footprint, curators, and execution venues stable.
