The main difference between Zengo and Uphold is that Zengo gives its users complete control over their private keys as it is a non-custodial wallet, whereas Uphold provides custodial services and essentially has the ultimate control over its user’s funds. Another key difference is that Uphold is a centralized exchange, whilst Zengo is a gateway to (DeFi) and Web3 applications. Uphold also provides extensive staking services where users can generate a passive income with crypto by storing it on Uphold and gaining a reward for doing so.
