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.
InfStones
InfStones is a specialized enterprise blockchain infrastructure provider built to handle full node operations, developer APIs, and dedicated validator staking. Rather than serving as an off-the-shelf retail yield app or custodial deposit portal, the platform targets institutional delegators, decentralized application developers, and asset managers who require programmatic access to proof of stake ecosystems. Its standout operational capability is broad multi-chain coverage spanning more than eighty public networks, backed by non-custodial staking workflows where participants retain control over their private keys.
Prospective users must evaluate operational tradeoffs. Deploying custom validator nodes and enterprise gateway infrastructure involves technical overhead and customized commercial quotes rather than clear flat fees. While non-custodial staking eliminates custodian default risk, participants remain subject to network slashing rules, lockup intervals, and server uptime requirements. For development teams and institutions managing substantial token balances, InfStones offers robust infrastructure with significant multi-chain depth.
