Our take

Who is behind Strike?

Strike is a US company founded by Jack Mallers; the app has been available in Europe since April 2024.[3],[2] Your contracting party in the EU is Zap (Strike) Europe Limited in Malta. The Maltese regulator MFSA authorised it on 25 June 2026 as a crypto-asset service provider (GlossaryCASP (crypto-asset service provider)A company that professionally provides crypto-asset services to customers – such as trading, exchange, custody or transfers. In the EU, every CASP needs an authorisation under MiCA.On the learning path: Stage 4 · Step 2 – Choosing a provider →In the glossary →) under GlossaryMiCA (Markets in Crypto-Assets Regulation)The EU regulation on markets in crypto-assets. Since 30 December 2024, exchanges, brokers and custodians in the EU have needed authorisation; the last transitional period ended on 1 July 2026. MiCA regulates providers, not Bitcoin itself.On the learning path: Stage 4 · Step 2 – Choosing a provider →In the glossary → – for custody, exchange for euros, order execution and transfers.[1],[2] You can use it in every EU country except Hungary, as well as in Iceland, Liechtenstein and Norway.[4] This profile covers that European offer. What the licence means is explained in MiCA & regulation.

Costs (as of September 2026)

Withdrawing to your own wallet

  • On-chain: you choose the delivery time. ‘Priority’ (about 10 minutes) and ‘Standard’ (about 1 hour) cost a network fee; ‘Flexible’ (about 24 hours) has no fee.[9]
  • GlossaryLightning NetworkA second layer on top of Bitcoin for fast, low-cost payments. Amounts move off the blockchain via payment channels; only opening and closing a channel ends up in a block as a normal transaction.On the learning path: Stage 1 · Step 3 – How does Bitcoin work? →In the glossary →: arrives in seconds; Strike passes on the small network fee without a markup.[9]
  • GlossaryTravel Rule (Transfer of Funds Regulation)An EU rule requiring crypto providers to send details of the sender and recipient with transfers. Since 30 December 2024, for more than €1,000 from or to your own wallet, the provider also checks that the address is yours.On the learning path: Stage 5 · Step 4 – First withdrawal →In the glossary →: Strike only sends to a new address once you have given details about the recipient. For an on-chain withdrawal of the equivalent of €1,000 or more to your own wallet, Strike may also ask for a selfie and a photo or screenshot of the device that holds the address.[9]

Step by step: Your first withdrawal to your own wallet.

Custody and risks

While your bitcoin are in the app, Strike is your GlossaryCustodian (custodial)A provider such as an exchange or app that holds the private keys for you. Convenient, because support can help if you lose your password – but you don’t hold the bitcoin yourself and depend on the provider paying out.On the learning path: Stage 5 · Step 1 – Understanding custody →In the glossary → and holds the keys.

Strike also advertises loans with bitcoin as collateral. They are not issued by the Maltese company but by a company in the Cayman Islands, and they are not regulated as credit in the EU. If the price falls, you may have to add collateral, or your bitcoin may be sold.[2]
