Our take
Ankr
Ankr stands out as an established multi-chain infrastructure and liquid staking provider. Founded in 2017, the protocol bridges the gap between decentralized node operations and accessible staking tokens. Instead of locking assets directly on native proof of stake blockchains where capital remains illiquid, participants receive liquid staking tokens like ankrETH or ankrBNB. These synthetic receipts automatically accrue consensus layer rewards or rebase in value while remaining usable throughout decentralized finance applications.
However, liquid staking introduces operational tradeoffs that self-custodial solo staking avoids. Users must navigate smart contract vulnerabilities, slashing exposure across distributed node operators, and protocol fee deductions deducted directly from gross returns. Ankr provides functional flexibility for active decentralized finance participants, but it requires comfort with non-custodial wallet interactions and composable smart contract risk.
Cypherock
Cypherock addresses one of the most persistent vulnerabilities in cryptocurrency self-custody by removing the need for a physical paper or steel recovery phrase. Its flagship product, the Cypherock X1, combines an open-source hardware vault device with four tamper-resistant NFC smart cards to shard private keys using a 2-of-5 Shamir secret sharing framework. To access funds or sign a blockchain transaction, users need only the vault device and any single card, meaning losing up to three cards never results in permanent capital loss.
Beyond native cold storage, the architecture serves as a centralized offline vault that can back up multiple existing wallets simultaneously. While the initial setup demands careful coordination of physical cards and PIN codes, Cypherock establishes an approachable, resilient recovery model that mitigates typical seed phrase exposure risks without sacrificing individual ownership or personal cryptographic independence.
