As part of verification, we may ask you to document the origin of your funds. This guide covers source of funds, source of wealth and the documents we accept.
You'll see these as steps in business verification, and source of wealth applies to some businesses only. If we need them later, we'll ask by email.
What they mean
Source of funds: the origin of the funds flowing through your account, such as customer payments, an investment round or a loan.
Source of wealth: how your business and its owners have accumulated their wealth over time.
One document can cover both. If the same activity explains both, such as your company's own revenue, you can use one document to support both checks.
Why we ask
Verifying the origin of funds is a standard requirement across financial services. It confirms that funds derive from legitimate activity and keeps Altitude secure for every business on the platform.
Source of funds documents
Upload any one of these:
Bank statements: business bank statements covering the last 3–6 months.
Investment or loan: the agreement, plus a transfer receipt or bank statement showing the funds arriving.
Token sale, SAFT or SAFE: the agreement, plus proof of disbursement.
Financial statements: audited financial statements or annual accounts.
Related company: that company's bank statements for the last 3 months, plus the agreement between the two companies.
Exchange statement: a recent centralized exchange statement showing your company's name, balances and transactions, signed and dated by an authorized representative.
Wallet attestation: a signed, dated statement confirming your company controls the wallet, with its addresses, networks, transaction links and the origin of the funds. Download the wallet ownership attestation template (PDF) from DocSend.
Source of wealth documents
Upload one document for each source you declared:
Business profits: company bank statements for the last 3 months, or your latest P&L or management accounts.
Employment or professional income: recent payslips or an employment contract.
Sale of a business or asset: the sale agreement and proof of the proceeds.
Investments, including crypto: a recent brokerage, exchange or wallet statement. For wallets, add proof you control it, such as a signed message or a small test transfer.
Inheritance or gift: the probate document or gift letter.
Tax filings: your most recent corporate or personal tax returns.
Any source: a signed letter from your accountant or lawyer, dated within the last 12 months.
