Two Lender Paths, One Document
US mortgage lenders split into two camps when it comes to crypto. The documentation requirement is similar — the question is whether you liquidate first or not.
Path 1 — Conventional / Jumbo
Fannie Mae, Freddie Mac, most jumbo
Crypto must be liquidated to USD before closing. The underwriter wants:
- • 60-day seasoning after deposit (bank statements)
- • Dated proof of where the USD came from — i.e. the on-chain history before sale
- • Exchange transfer records showing the sale
CryptoBankStatement covers the on-chain history — the part your bank statement and exchange records can’t show.
Path 2 — Crypto-Backed / Non-QM
NAF Cash, Milo, Figure, non-QM jumbo
Lender holds crypto directly as collateral or counts it as a reserve. The underwriter wants:
- • Current verifiable on-chain holdings
- • 60–90 day stability of those holdings
- • Self-custody confirmation (you control the keys)
CryptoBankStatement provides all three in one PDF — no liquidation required.
What US Underwriters Expect
Every Selling Guide and non-QM playbook asks for the same three things — they just use different language for it.
Seasoning trail
A dated record of every deposit and withdrawal across the 60–90 days before close. Underwriters call this "sourced and seasoned."
USD equivalents
BTC or ETH amounts mean nothing without dollar values at the time of each transaction. Statements include historical USD pricing on every row.
Independent verification
Every transaction links back to the block explorer. The underwriter, attorney, or auditor can independently confirm any line.

Common Questions
Will Fannie Mae or Freddie Mac conventional loans accept crypto as down payment funds?
Both Fannie Mae and Freddie Mac Selling Guides treat digital currency as an unacceptable source for closing funds while it remains in crypto form. To use crypto for a conventional conforming loan, you must liquidate to USD and document the deposit into a regulated bank account, typically with 60 days of seasoning. A CryptoBankStatement covers the on-chain history of those funds before liquidation — the part your bank statement cannot show. Specific guidance: Fannie Mae Selling Guide B3-4.1-04 and Freddie Mac Bulletin 2022-7.
Which lenders accept crypto holdings directly (without liquidation)?
Specialist non-QM and crypto-collateralised lenders include Milo (crypto-backed mortgage), NAF Cash, Figure Lending, certain regional credit unions, and select jumbo programs. Each has its own documentation standard — but all want a structured, dated statement of your on-chain holdings rather than a Coinbase screenshot or block-explorer URL. Confirm with your loan officer before applying.
How much seasoning history do I need to show?
Conventional Fannie Mae / Freddie Mac guidance is 60 days of seasoning after deposit. Specialist crypto lenders typically want 60–90 days of on-chain history before liquidation as well. For jumbo loans the window can stretch to 6 months. Generate a statement covering at least the 60–90 days preceding liquidation (or your current holdings window if not yet liquidated) and your loan officer will tell you if they need more.
What if my crypto came from an exchange — do I still need a wallet statement?
If the funds never left the exchange, an exchange statement (Coinbase, Kraken, Gemini) is usually sufficient. If you self-custodied at any point — moved crypto to a hardware wallet, MetaMask, or any address you control — the underwriter will want a wallet statement covering that self-custody period. The two records together tell the complete source-of-funds story.
Does converting crypto to USD trigger capital gains?
Yes. The IRS treats digital assets as property; converting crypto to USD is a taxable disposal. Your basis (what you paid) versus your sale proceeds produces short-term or long-term capital gain or loss, reported on Form 8949 and Schedule D. The statement gives you and your CPA the dated transaction trail to compute basis correctly. We do not provide tax advice — work with a CPA.
Can my closing attorney verify the statement?
Yes. Each statement carries a unique verification ID and a public verification page at cryptobankstatement.com/verify. Your attorney or title company can independently confirm the statement was generated from public blockchain data and check key facts (wallet address, period, transaction count) without you needing to forward anything beyond the PDF.
