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.
MetaMask Card
The MetaMask Card introduces a distinct structural shift in the crypto payment landscape by linking self custody Web3 wallets directly to the global Mastercard payment network. Developed through a partnership between Consensys and payment infrastructure provider Baanx, the product circumvents the standard requirement of transferring digital assets to a centralized exchange balance prior to spending. Instead, cardholders retain their private keys and token ownership on the Linea network up until the precise second a merchant point of sale purchase is authorized.
While this architecture significantly reduces custodial exposure and platform counterparty risk, it also introduces specific operational boundaries. Users must navigate onchain liquidity constraints, network bridging requirements to Linea, potential foreign exchange spreads, and regional pilot restrictions across the UK and European Economic Area. For decentralized finance participants who prioritize custody retention over high cashback tiers, the offering provides a practical bridge to retail commerce.
