Share-Based Payment Arrangement, Expensed and Capitalized, Amount [Line Items]
Terms of Award					Following the Merger, no further awards may be granted under the 2019 Equity Plan; however, awards granted under that plan will remain subject to the terms and conditions of the 2019 Equity Plan. Under the 2025 Equity Plan, an aggregate number of shares equal to the sum of (i) 10% of the fully-diluted shares of Fold Holdings, Inc. Common Stock as of the Closing, (ii) the number of shares that remained available for issuance under the 2019 Equity Plan as of the Closing and (iii) the number of shares that were subject to awards under the 2019 Plan as of the Closing and which, following the Closing, became available for grant under the 2025 Equity Plan, were initially reserved under the 2025 Equity Plan.
Share-Based payment award, description modified	a service condition that is typically satisfied based on the grantee's continuous service over 48 months with a one-year cliff vesting requirement (though some RSUs have been granted with different service-vesting schedules, including without the one-year cliff), and a performance condition related to the consummation of a liquidity event defined in the award agreements as the first to occur of a change of control or the first sale of Common Stock pursuant to an IPO. The Merger with FTAC Emerald on February 14, 2025 was deemed to have satisfied the performance condition criteria. Following the Merger, the Company's RSUs are subject to vesting requirements of each individual Award grant, which will typically include only a service condition based on the grantee's continuous service over 48 months with a one-year cliff vesting requirement.
