No Proof of Where Your Crypto Came From?
We build the proof.

In the early days of crypto (2010-2016), there were no exchanges with KYC, no bank integration, and no regulatory framework. People bought Bitcoin with cash through LocalBitcoins, received it as payment for services, mined it with GPUs, or got it as a gift. Nobody kept records because nobody expected to need them.

Now, years later, these same people try to cash out on a regulated exchange — and the exchange asks for source of funds documentation that simply does not exist. The exchange is not being unreasonable; they are legally required to verify the source of funds. But they are applying modern regulatory standards to assets acquired before those standards existed.

Common scenarios

• Cash purchase via LocalBitcoins/P2P: You met someone in person, paid cash, and received BTC to your wallet. No receipt, no record. LocalBitcoins has since shut down.
• Mining (2011-2016): You mined BTC or ETH with a GPU. The mining pool has shut down. The rig is gone. You have no logs.
• Gift: Someone gave you crypto as a gift — for a wedding, birthday, or just because. No documentation was created.
• Defunct business: You earned crypto through a business that no longer exists. The business records are gone.
• Mixed sources: Your crypto came from many sources over the years — some documented, some not. You cannot untangle the trail.
• Unintentional mixer exposure: You received crypto that, unknown to you, had passed through a mixer. Your wallet is now flagged.

For mined crypto

If you mined the crypto, the blockchain contains the proof. Mining rewards originate from "coinbase transactions" — the block rewards encoded in the blockchain itself. We use blockchain forensics to trace your crypto back to the specific blocks that were mined, proving that the funds originated from mining activity. We then prepare a legal declaration supported by the forensic evidence, explaining that you mined the coins at a specific time using hardware that is no longer available.

For cash purchases via P2P

If you bought crypto for cash through LocalBitcoins or in-person P2P, we trace the blockchain to show that the crypto entered your wallet from a specific address at a specific time — consistent with a P2P purchase. We then prepare a sworn declaration describing the circumstances: where you met the seller, approximately when, how much you paid, and why no receipt was created. This is supported by the blockchain evidence showing the transfer.

For gifts

If the crypto was a gift, we trace the blockchain to the donor's wallet and, if possible, document the donor's source of funds. If the donor is available, we obtain a sworn statement from them. If the donor is unavailable, we prepare a declaration from you explaining the gift, supported by blockchain evidence of the transfer.

For mixed or tainted funds

If your crypto has passed through addresses that are flagged (mixers, darknet, sanctioned addresses), we conduct a full blockchain forensics analysis to identify the specific transactions that caused the flag. We then prepare a legal argument that you had no knowledge of or involvement with the flagged activity, supported by the overall transaction pattern showing legitimate use.

Exchanges are increasingly accepting blockchain forensic evidence as source-of-funds documentation — particularly when it is presented by legal counsel rather than by the account holder directly. The key is framing: we do not just provide raw blockchain data; we provide a legal declaration that interprets the data and explains why it constitutes sufficient evidence of legitimate source.

In our experience, major exchanges (Binance, Kraken, Coinbase, OKX) accept blockchain forensic evidence in approximately 75-80% of undocumented SoF cases we handle. The success rate is highest for mining origin (nearly 90%) and lowest for mixed/tainted funds (approximately 60%). We provide a realistic assessment of your specific case after the initial analysis.
