There's a version of crypto yield that most people have quietly made peace with: you hand your assets to a platform, the platform does the staking or the farming, and you trust that it'll all work out. It mostly does. Until it doesn't.
That tradeoff has always sat awkwardly with the whole point of a hardware wallet. You go through the effort of keeping your keys off the internet, split across tamper-resistant hardware, only to bridge them out the moment you want to do anything productive with your assets.
We've been thinking about how to close that gap for a while. The integration we're announcing with Everstake is our answer to it.
Everstake runs validator infrastructure across 30+ active networks and has $7B+ staked to date. They're also one of the few infrastructure providers that builds with a non-custodial constraint as a starting point rather than an afterthought. That's what made the conversation interesting.
The integration brings three of their products into cySync:
All three run directly inside cySync. Every deposit, delegation, and redemption is signed on the X1 Vault device. The key model doesn't change — your private key stays sharded across your 5 components throughout.

Staking through cySync works the way you'd hope it does. You pick an asset and sign the delegation by tapping one of your X1 Cards against the vault. The transaction goes to the network. Rewards accrue on-chain. Everstake is our exclusive staking partner, so all delegations route through their validator nodes.
What doesn't happen: your assets don't move to a custodian. Everstake's validators are the delegation target, not a third-party custodian. You can un-delegate whenever you want, subject to each network's un-bonding period.
The Everstake Wallet SDK handles delegation, claiming, and un-staking through a unified interface across all supported networks, which is part of why it works cleanly inside cySync without needing a separate app or an external signing flow.
The High Yield Stablecoin Vault is worth understanding properly before you use it, because "7%–12% APY on stablecoins" is the kind of number that deserves scrutiny.
The yield comes from partner-managed liquidity farming strategies on USDC (Ethereum, Base) and USDT (Ethereum), running through permissionless smart contracts. Strategies are actively managed, with a dedicated Risk Manager and predefined safety parameters. It's not a fixed-rate product. The APY range is indicative.
When you deposit, the vault mints share tokens to your wallet. Those tokens represent your position. When you want out, you have two options: instant redemption at a 0.5% fee, or standard redemption through a queue that takes roughly 3 days with no fee. Either way, the underlying USDC or USDT comes back to your wallet in a single on-chain transaction.
The USDC Prime Solana Vault is a different product for a different situation. It's built on Kamino Finance, with Gauntlet setting and monitoring the strategy. If you hold USDC on Solana that's just sitting there, this vault routes it into a curated Kamino position. The strategy is deposit-only and runs without leverage, so there's no liquidation exposure. Redemption is T+0 under normal conditions, subject to Kamino vault utilization, with a 20% fee on rewards.
In both vaults, you hold the share tokens. Everstake, Gauntlet, Kamino, and Cypherock cannot move your funds. Redemption is permissionless.
The Cypherock X1 splits your private key into 5 cryptographic shards using Shamir's Secret Sharing. One shard lives in the X1 Vault. The other four live in your X1 Cards — NFC smartcards with EAL 6+ secure elements. To sign anything, you tap any one card against the vault. The full key is never reconstructed in one place.
That architecture works particularly well for yield products because you're signing transactions more regularly than you would with plain storage. Staking rewards, vault deposits, redemptions — each one is a transaction. With a seed-phrase wallet, that frequency creates exposure. With the X1, the signing surface is the same whether you're doing it once a year or once a week.
The X1 supports 19,000+ assets, connects to dApps via WalletConnect, and is compatible with BIP39 wallets including Ledger, Trezor, MetaMask, and Trust Wallet. It's been independently audited by Keylabs, verified as reproducible by WalletScrutiny, and is listed on bitcoin.org.
This isn't a managed account. Everstake runs the infrastructure and the SDKs. Gauntlet curates the Solana vault strategy. Kamino is the execution venue. Cypherock is the hardware layer where you sign. Nobody in that chain is acting as a fiduciary or holding your assets on your behalf.
That matters because the whole point of doing this inside a hardware wallet is that the custody model stays intact. If you want a platform to manage things for you, there are simpler products for that. This is for people who want the yield without handing over the keys to get it.
Cypherock acts solely as a hardware interface and signing layer for this integration.
