How Do I Screen Inherited Crypto Before Moving It to an Exchange?

TL;DR - Before moving inherited crypto to an exchange, screen the wallet's full history for sanctions, mixer, and stolen-funds exposure, then gather inheritance paperwork so you can prove a legitimate source of funds.

When you inherit a relative's crypto, you usually receive a seed phrase or private keys with no paper trail behind them. You did not buy the coins, you cannot explain every past transaction, and you often have no idea where the deceased moved funds years ago. Most inheritance guides cover probate and tax but skip the part that actually freezes accounts: an exchange treats a large deposit from an unknown wallet as a source-of-funds risk, and a single tainted transaction buried in that wallet's history can hold the entire balance for weeks.

Why does inherited crypto trigger an exchange review?

Exchanges run automated screening on every incoming deposit, and they read the sending wallet's history, not just the transfer that reaches them. An inherited wallet can hold years of activity the heir never saw: trades on platforms that no longer exist, transfers to and from mixers, or payments to addresses later added to a sanctions list. When the deposit lands, the monitoring tools score that history and may pause the funds pending a manual review.

The heir also arrives with no purchase records. With crypto you bought yourself, you can point to a bank transfer or an exchange invoice to explain the money. Inherited coins have none of that, so the compliance team cannot match the deposit to a known funding event. That gap, combined with the wallet's opaque past, is what turns a routine deposit into a source-of-funds request or an outright account hold.

How do you check an inherited wallet's history before you touch it?

Review the wallet before you send a single coin to an exchange. Open a block explorer such as Etherscan and read the full transaction list of the inherited address, watching for transfers tied to mixers, sanctioned entities, or known thefts. Manual review is slow and easy to misread, because a risky counterparty rarely announces itself in plain text and a flagged address looks identical to a clean one on the ledger.

To see the whole picture in one pass, you can screen the inherited wallet with Plastron and check for sanctions, mixer, and stolen-funds exposure across Ethereum and six other EVM chains before you move anything. Knowing the risk in advance lets you decide whether to deposit, hold the coins where they are, or get legal advice first. For background on what these tools actually read, see our guide to crypto wallet screening.

Pay attention to indirect exposure too. A wallet that never touched a sanctioned address directly can still inherit risk if it received funds a hop or two away from one. That is the same trail exchanges follow when they decide whether to clear a deposit, which is why understanding how exchanges trace a deposit's origin helps you predict their decision before you make it.

What documents prove inherited crypto is a legitimate source of funds?

If an exchange asks where the money came from, the inheritance itself is your answer, but you have to evidence it. Assemble a short pack before you deposit so you can respond quickly instead of scrambling while the funds sit frozen. The stronger the paper trail, the faster a review clears.

The core items are a death certificate or grant of probate, the will or a letter showing your authority as executor or beneficiary, any original purchase or exchange records the deceased left behind, and a screening report for the wallet. If you need help structuring the written explanation, our walkthrough on how to write a source-of-funds letter for a crypto exchange covers the format compliance teams expect.

What mistakes get an inheritance withdrawal frozen?

The most common error is depositing the entire balance in one transfer to a brand-new exchange account. A large first deposit from an unknown self-custody wallet, with no prior trading history on the account, is exactly the pattern monitoring systems escalate. Spreading the move into smaller transfers does not help either, because deliberate splitting can read as structuring and draw more attention, not less.

The second mistake is moving funds before you check the wallet, so you only learn about a mixer or sanctions link after the exchange flags it. By then the coins are in their custody and you are arguing from a frozen position. The third is discarding the deceased's records during estate cleanup; old exchange statements and email receipts are often the only proof that the original coins were bought legitimately. Keep everything until the funds have cleared and settled in your own name.

FAQ

Can an exchange seize inherited crypto if the wallet has a flagged history?

An exchange can freeze a deposit during review, and if the funds are directly tied to sanctions or theft it may refuse to release them and file a report. Inheritance does not erase a wallet's on-chain history, which is why screening before you deposit matters more than explaining afterward.

Do I owe tax based on the deceased's purchase price or the value when I inherited?

Tax treatment varies by country and is separate from AML screening. Many jurisdictions reset the cost basis to the market value on the date of death, but you should confirm with a local tax professional. This article covers compliance and screening, not tax advice.

What if I cannot find any of the deceased's purchase records?

Missing records are common with inherited crypto. Document what you do have, the death certificate and your legal authority, and use a clean screening report to show the wallet carries no sanctions or stolen-funds exposure. A transparent explanation plus a clean risk report is usually enough for a standard review.

Is it safer to keep the coins in the inherited wallet instead of moving them?

Holding avoids an immediate deposit review, but the wallet's history does not improve over time, and you will face the same screening whenever you eventually cash out. Checking the address now tells you whether a future deposit is likely to clear, regardless of when you move the funds.
