Strike

Custodial accounts, Lightning payments and withdrawal to a personal wallet

Strike lets you buy bitcoin, receive payments and send savings to your own wallet. Between buying and taking control, however, there is an important step: withdrawing from the service’s custody.

Strike is a financial app for buying, selling and sending bitcoin, with features depending on country and account type. It also supports Lightning Network, a network for fast bitcoin payments. Strike manages the balance in the app: the user does not hold the private keys that authorize spending. Self-custody begins when the funds reach a wallet whose keys the user actually controls. Paying over Lightning or saving a withdrawal address does not, by itself, cross that boundary.

Imagine a friend in the United States recommending a Strike feature that you cannot find in your Czech app. That need not be a fault: several companies operate under the brand, with different offerings. Ordinary US accounts are provided by Zap Solutions, Inc.; supported European countries and the UK use Zap (Strike) Europe Limited; other supported countries use E4 S.A. de C.V. US banking procedures and loans therefore cannot simply be applied to a Czech account. The European company is authorized in Malta under MiCA, the European rules for crypto-assets. New York’s NYDFS register lists virtual currency and money transmitter licenses for the US company from February 2026; these are not worldwide permission for every feature. [1] [11] [12]

A purchase adds bitcoin to your app balance. Strike holds it for you in custody; it does not hand you your own private keys. Under the European terms, the bitcoin legally belongs to you, but the service handles sending it. The euro balance and a bank account also need to be distinguished. European client money is kept separate from company funds through a payment partner and a bank. Zap (Strike) Europe Limited is not itself a bank or electronic money institution. Euro deposits use SEPA, the European bank-transfer system: they must arrive in euros from an account in your own name. [2] [3] [4] [12]

You buy bitcoin and want to move it straight to your wallet, yet encounter a wait unrelated to the Bitcoin network. The US guide distinguishes available funds from pending balance, funds still awaiting release. With ACH, a US bank-transfer system, Strike may allow trading before the transfer has settled. Sending must wait for settlement and any additional account-specific hold. Exchanging money for bitcoin does not remove that wait. Eligible personal accounts may get limited early access through Strike Instant, but this is not an entitlement for everyone. The US process describes neither a European SEPA deadline nor a wait for bitcoin transaction confirmation. [5]

Instead of a long string, you can give someone your username followed by @strike.me. This format is called a Lightning Address. It is neither an email inbox nor an ordinary address for a transfer recorded directly on Bitcoin’s blockchain. The paying wallet uses it to request a Lightning invoice, a request for payment. The recipient’s settings matter too: incoming bitcoin may remain bitcoin or be converted to a cash balance. If the sender pays from a cash balance, conversion into bitcoin happens at that end. The network used therefore does not, by itself, tell you which currency you end up holding. [6]

Buying and then sending are separate operations. For the first, check the price and trading fee; for the second, the cost of delivery. The European guide lists paid on-chain options Priority and Standard alongside the slower, free Flexible option. On-chain means a transfer recorded on Bitcoin’s base network. Lightning may instead carry a small fee for routing the payment through its network. Paying from cash adds a spread, a markup included in the conversion rate. A free withdrawal therefore does not make the purchase or conversion free too. Before confirming, compare your total outlay, the bitcoin received and the selected speed; an estimated delivery time does not guarantee immediate confirmation. [7] [13]

You might buy for the same cash amount each week. This approach is called DCA: the amount of bitcoin bought changes with the current price. Check the amount, time and funding source in your Strike plan. The European fee schedule waives personal-account trading fees after the first week, or from the second purchase for weekly and monthly plans; this cannot automatically be extended to businesses or every other cost. If funds run short, check notifications and the plan’s status. European help says the plan cancels after three such failures in total, not necessarily consecutively. The product update page instead describes pausing after three consecutive failures. The documents disagree, so identical behavior across all accounts cannot be promised. An enabled schedule alone does not guarantee a completed purchase. [8] [7] [14]

Where an account offers Auto-withdrawal, it can send bitcoin to your own wallet once a chosen threshold is reached. That threshold does not authorize the use of funds that are still unavailable. The international guide also lets you set a reserve to leave on the account. Withdrawals draw from the main bitcoin balance; amounts set aside in compartments called stacks are excluded. It is therefore inaccurate to say that the whole account always leaves. The guide allows twelve hours to cancel a queued withdrawal and states that the transaction is broadcast to the network within twenty-four hours of reaching the threshold, without a fee. Broadcast is not yet block confirmation: inclusion in the shared transaction record comes later. [9] [5]

Automation does not make the destination address less important. Given a list of automatic-withdrawal addresses, Strike uses them in sequence, then reuses the last one until you add more. A fresh address for every withdrawal is therefore not guaranteed indefinitely. Verify a changed destination in your own wallet and check receipt after the transfer. Account conditions still matter: unlimited numbers of purchases do not mean unlimited size per trade or a promise that every transfer will proceed without checks. In Europe, Strike may require recipient details before sending under Travel Rule, rules for passing information about transfers. Estimated delivery for a paid speed starts only after this verification is complete. Receipt in a wallet with your own keys finally completes the journey from buying to self-custody.
