The fate of your cryptocurrency depends on whether you use a custodial or non-custodial wallet. Understanding this distinction before a problem arises determines whether you retain control of your funds.

For a custodial wallet, if the provider ceased operating, the process for returning user funds — and how quickly — depends entirely on that provider's own wind-down procedures and the regulatory framework it operates under, which varies by company and jurisdiction. The provider holds the keys to your funds, so their internal processes and the laws governing them determine what happens next. Some jurisdictions require segregated client funds, while others do not, and this difference matters when a company closes.
For a non-custodial wallet, the user's own seed phrase still controls the funds regardless of whether any specific company continues operating, since the funds live on the blockchain itself, not inside the company's own systems. If the wallet app disappears, you can import your seed phrase into another compatible wallet and access the same funds. This is why keeping your seed phrase secure and backed up is the single most important step for non-custodial users.
Reviewing a provider's terms of service for what it says about fund custody, and whether client funds are kept segregated from the company's own operating funds, is a way to understand what protection exists before an issue arises, not after. Terms that mention segregated accounts or third-party custodians suggest a structure designed to return funds if the provider shuts down. Terms that are vague about custody arrangements offer less clarity about what would happen in that scenario.
A card linked to a wallet stops working if the underlying service shuts down, the same way any card becomes unusable if its issuing program ends, regardless of whether it was bank-issued or crypto-funded. The card is a payment interface, not a store of value itself. Nexus Pay offers a Visa card funded from a non-custodial wallet across six networks, so your seed phrase controls the funds even if card services were interrupted.
Custodial wallets offer convenience but require trust in the provider's solvency and procedures. Non-custodial wallets require you to manage your own seed phrase but give you direct control regardless of any company's status. Neither model is risk-free: custodial users face counterparty risk, while non-custodial users face the risk of losing their seed phrase. The right choice depends on which risks you are better equipped to manage.
