OCAPS: crypto-asset ownership certificate with proof of origin
The OCAPS (On Chain Asset Statement) proves three things in a snapshot as of the issue date: which crypto-assets you hold, that they are yours and where they come from. It is the report for notaries, inheritances, holding vehicles, custodians and platform KYC processes.

What it certifies
What the OCAPS proves
It answers one question: what does this person hold, is it theirs and where does it come from? Every statement in the report rests on evidence that can be verified.
| What it proves | How it is proven | Where to find it |
|---|---|---|
| Identity of the holder | KYC and signed statements from the holder. | Section 1 |
| Scope | List of all declared wallets and platforms. | Section 2 |
| Control of each wallet | Satoshi Test for each address, with the full hash of the test transcribed. | Section 3 |
| No sanctions | Screening against the OFAC, EU, UN and UK lists, PEP and adverse media, with a result for each list. | Section 4 |
| Source of funds | On-chain tracing from the money invested to the current positions, with reconciliation. | Section 5 |
| Platform risk | Risk score for each platform (low, medium or medium-high) and an overall rating. | Section 6 |
| Positions and value | Unified table: address, evidence, asset, quantity and valuation, with source and time. | Section 8 |

The tests
Satoshi Test, screening, tracing and valuation
An OCAPS does not rely on what the holder declares, but on what can be checked. These are its four technical tests.
Satoshi TestControl of each wallet
The holder sends a minimal amount from each address, following our instructions. The hash of that transaction is transcribed in full.
- For each address
- Full hash
- Date of the test
ScreeningSanctions, PEP and media
The holder and related persons are checked against sanctions lists, PEP databases and adverse media, with a result for each list.
- OFAC, EU, UN, UK
- PEP
- Adverse media
TracingFrom the money invested to the positions
We rebuild the path from the money contributed to the current positions and reconcile it with the platforms’ transaction histories.
- Contributions
- On-chain path
- Reconciliation
ValuationAsset snapshot
All positions in a single table: address, evidence, asset, quantity and valuation at a single point in time, with source and time. The total adds up.
No evaluative adjectives: where an adjective would go, the report gives the figure.
ResultHow the report ends
Result
Legal conclusion with an express result.
Observations
Any caveats, in writing.
Signature
A lawyer registered with the Bar, with an electronic signature.
When to request it
Who the OCAPS is for
Notary
That the crypto-assets exist, belong to the person appearing before the notary and have a traceable origin.
The notary needs a snapshot of the assets, not your full tax profile. See buying property with crypto.
Inheritance or estate
Which crypto-assets there are, in which wallets and what they are worth.
Inventory and valuation as of a given date, with ownership proven. See crypto inheritance.
Holding vehicle or company
What is being contributed, and that the person contributing it is its owner.
Scope, control of the wallets and valuation of what is contributed.
Custodian
That the depositor controls the wallets and that the funds are not exposed to sanctions.
Satoshi Test, screening and risk for each platform.
Platform KYC or KYB
Ownership, origin and risk of the funds to be deposited.
It answers the usual customer onboarding questions.
When the OCAPS falls short
In these cases, an OCACS is the better choice:
- A bank’s compliance department will review it.
- The bank has already sent you a request for information or has held a transfer.
- There is a spouse with community property (gananciales) or there are interposed companies.
- Your wealth comes from more than what you invested in crypto: a business, an inheritance or real estate.
- You need to prove what you have declared to the Spanish Tax Agency.
Are you going to present your crypto-assets to a notary or a platform?
We prepare the OCAPS with Satoshi Test, screening, on-chain tracing and valuation, signed by a lawyer.
Frequently asked questions
OCAPS: common questions
What is the OCAPS?
It is the On Chain Asset Statement: a report signed by a lawyer that proves which crypto-assets a person holds, that they are theirs and where they come from, as a snapshot at the issue date. It includes a Satoshi Test, screening, on-chain tracing, platform risk and valuation.
What is the Satoshi Test?
It is a control test: the holder sends a minimal amount from each address, following our instructions. The transaction shows that whoever makes it controls the keys to that wallet. In the OCAPS, the hash of each test is transcribed in full, address by address.
What is the difference between the OCAPS and the OCACS?
The OCAPS focuses on the assets: what there is, who it belongs to and where it comes from. The OCACS focuses on the relationship with a bank: it adds the customer profile, the source of all wealth, tax, risk and expected activity. The OCACS includes a full OCAPS.
Can I use the OCAPS with my bank?
It can form part of the documentation. But if the compliance department will review it to open or keep your account, the report designed for that decision is the OCACS.
How long is an OCAPS valid?
It certifies the situation on its issue date and does not include periodic updates. It has no legal expiry date: each recipient decides how old a report it will accept.
What do I need to provide?
Your ID, the list of wallets and platforms, your exchange transaction histories and the bank statements for the money you contributed. You also carry out the Satoshi Test for each address. Everything is handled through our portal.
Can I move from an OCAPS to an OCACS later?
Yes. The full OCAPS goes into the OCACS, so the Satoshi Test, the inventory and the reconciliation are not repeated: only the new blocks are added.
Can the OCAPS be extended without going all the way to an OCACS?
Yes, with specific modules: beneficial ownership, tax, or responding to red flags. The report is still an OCAPS, with what you have been asked for and nothing more.
Methodology
What the OCAPS is based on
The report is prepared in accordance with anti-money laundering and data protection legislation, using KYT methodology.
Verifiable: every statement points to evidence: a hash, a list or a transaction history.
No adjectives: where an assessment would go, the figure goes.
Dated snapshot: the valuation is made at a single point in time, with source and time.
Law 10/2010
Anti-money laundering
The due diligence framework that notaries, banks and platforms apply when reviewing the source of funds.
GDPR
Data protection
The data of the holder and related persons is processed only for the purpose of the report.
KYT
On-chain analysis
Know Your Transaction: risk analysis of the addresses and transactions within the scope.
OCAPS or OCACS
Differences between the OCAPS and the OCACS
Both share the same technical tests. What changes is the question they answer, the recipient and what they analyze. A simple rule: if a bank’s compliance department will read it, OCACS; in all other cases, OCAPS.
| Aspect | OCAPS | OCACS |
|---|---|---|
| Question | What does this person hold, is it theirs and where does it come from? | Can the bank take on or maintain the relationship with this person? |
| Recipient | Notary, inheritance, holding vehicle, custodian, platform KYC. | Compliance department of a financial institution. |
| Subject | The assets. | The business relationship. |
| Time frame | Snapshot as of the issue date. | Past and future: expected activity and ongoing due diligence. |
| Origin | Of the funds invested in crypto. | Of all wealth and of the funds, separately and by tax year. |
| Risk | Risk score for each platform. | Inherent money laundering risk, measures and residual risk. |
| Tax | Not covered. | Personal income tax (IRPF) by tax year, third-party tax reports and Form 721. |
| Length | 9 to 27 pages. | 27 to 32 pages, plus annexes. |
Everything the OCAPS proves is included in the OCACS. More detail in OCACS: enhanced due diligence report.

OCAPS: crypto-asset certificate with on-chain analysis
The OCAPS (On Chain Asset Statement) is Molina Law Boutique’s crypto-asset ownership certificate. As a snapshot at the issue date, it proves which crypto-assets a person holds, that they control them and where the funds used to acquire them came from. It is signed by a lawyer registered with the Bar and always follows the same structure, so that notaries, custodians and platforms find each piece of evidence in the same place.
What the Satoshi Test is
The Satoshi Test is the control test that many exchanges and custodians ask for: the holder sends a minimal amount from their wallet to show that they hold its keys. In the OCAPS it is done for every address within the scope, and the hash of each test is transcribed in full.
Screening and tracing
The report checks the holder and related persons against the OFAC, EU, UN and UK sanctions lists, PEP databases and adverse media. It then rebuilds the source of funds on-chain and reconciles it with the platforms’ transaction histories, using KYT methodology and in line with Law 10/2010 and the GDPR.
OCAPS or OCACS
When the recipient is a bank’s compliance department, the right report is the OCACS, which includes a full OCAPS and adds the holder’s profile, the source of all their wealth, tax, money laundering risk and expected activity. If you only need to prove the source of funds for one transaction, see also the crypto certificate.
