Whether a crypto wallet is safe depends on the type of wallet, the provider's practices, and your own behavior. No single answer fits all wallets.

A custodial wallet's security depends on the provider's own infrastructure — encryption, access controls, operational practices — since the provider holds the keys on the user's behalf. This means you trust the provider to secure your funds, much like trusting a bank. Reputable custodial wallets use industry-standard encryption and security audits, but the risk is that a breach or operational failure at the provider level affects all users.
A non-custodial wallet's security depends entirely on how well the user protects their own seed phrase, since no company can recover funds if it is lost or stolen. You control the keys, which means no third party can freeze or lose your funds, but it also means you bear full responsibility for safeguarding the seed phrase. If someone gains access to your seed phrase, they control your funds.
Passwordless authentication methods (like signing in through a linked Telegram or Google account, verified server-side) reduce the risk of a password being guessed or reused from a data breach elsewhere.
This approach is common in modern custodial wallets and adds a layer of protection.
No wallet, custodial or not, protects a user from voluntarily sending funds to a scammer or approving a malicious transaction — a secure wallet does not replace caution about what is being approved. Additionally, funds held as a stablecoin balance still carry the operational risk that the stablecoin issuer maintains adequate reserves, distinct from the wallet or card provider's own security. Nexus Pay, a crypto wallet with a Visa card and in-app coin swaps, uses custodial security practices, but like any wallet, it cannot prevent user error or issuer risk.
