Summary

Strike (operated by Zap Solutions, Inc.) is a Bitcoin and Lightning Network payments application founded by Jack Mallers. The platform has faced scrutiny over a 2023 data breach it initially denied, the use of Tether (USDT) as a backing for purported USD cash balances for non-US users, and a 2026 proposed merger with Twenty One Capital (XXI) that raises serious conflict-of-interest concerns given Mallers serves as CEO of both entities.
