Zengo was founded in Tel Aviv in 2018, originally as KZen Networks, with one idea: a self-custody wallet should not depend on a piece of paper. Instead of a seed phrase, Zengo uses multi-party computation to split the signing key into two shares, one on your phone and one on Zengo's servers, so neither side can move funds alone and there is nothing to write down. Recovery uses your email, a face scan and an encrypted recovery file, and Zengo says the design has never had a wallet drained. It was the first consumer wallet to ship this way, and it remains the reference for it.
The buy button is a different company. Zengo named MoonPay its exclusive buy-and-sell provider, so a purchase inside the app is a MoonPay purchase: MoonPay's verification, MoonPay's 4.5% card rate with a minimum of about $3.99, MoonPay's ACH at about 1% where available, and MoonPay's state coverage, which is why Zengo's help center lists some features as unavailable in New York, Louisiana, Texas and the U.S. Virgin Islands. Zengo Pro, at $19.99 a month or $129.99 a year, adds security features and a discount of up to 50% on those purchase fees.
Anytime Capital is a U.S. money services business that serves customers worldwide, with a storefront on Piedmont Road in Atlanta, an office in Miami's One Biscayne Tower, a phone number that reaches a person, and rails from Apple Pay to cash and same-day wire. It also gives customers a free non-custodial wallet, so the comparison is not wallet versus no wallet; it is which company you want on the other end when you are buying.
