Our services
KlearChain handles three different crypto situations (repatriation, tax return & scams) with one and the same method: tracing your crypto-assets and presenting the results in a case file designed to be understood and accepted by all stakeholders (lawyer, bank, the Belgian tax authorities, the police and the courts).
Taxation
Declare my crypto-assets
Since 1 January 2026, Belgium taxes capital gains on financial assets (shares, bonds... and cryptos) at 10%. The law seems simple; its application is not: is a crypto-to-crypto exchange or a conversion into a stablecoin a taxable event? Does staking fall under income from movable property? No calculation method is imposed by the Belgian tax authorities. Tax characterisation remains decisive, both for your profile (normal management of private assets, miscellaneous income at 33%, professional) and for each transaction, and requires proper historical traceability.
Your tax return, ready to submit
- Complete reconstruction of the crypto transaction history (multi-platform, multi-period, including DeFi, NFT and staking).
- Calculation of capital gains and losses.
- Pre-filled tax annexes and recommendations for MyMinfin.
In-depth analysis
Detailed characterisation of your profile and each type of transaction (swaps, conversions into stablecoins, staking, etc.), and securing grey areas.
Tailored structuring
For complex wealth situations, a tax strategy developed with our partner tax lawyers.
Source of funds
Documentation of the link between your initial bank funds and your crypto-asset acquisitions, if your situation requires it.
For whom: individuals subject to tax on their crypto-asset capital gains, and their advisers (lawyers, accounting firms, family offices).
Banking compliance
Repatriate my funds to my bank
A bank must verify the source of funds it accepts. This is a due diligence obligation specific to the bank that it cannot delegate to anyone: it does not impose any format, template or service provider. What makes the difference is a complete, sourced and verifiable case file. An Excel spreadsheet you put together yourself is no longer enough. But our expertise is.
The complete technical case file
- Reconstruction of the source of funds.
- Full traceability of the crypto transaction history and identification of counterparties.
- Tax analysis validated technically and legally by our team.
Directly usable by your private bank or your lawyer. We cannot guarantee your bank's decision; no one can. We ensure that it has everything it needs to make it.
The last mile to your bank
Structured memorandum for the Compliance department, preparation of all supporting documents, and assistance during exchanges with your bank until the funds are accepted.
For whom: crypto-asset holders who need to integrate these funds into their banking assets (property purchase, investment, estate planning), and their advisers.
Investigation and support
Recover after a scam
Our role: to help you regain control. Locate the funds, provide your lawyer with the elements to take action, and remain by your side throughout the procedure.
EUR 38.3 million lost to investment fraud in Belgium in 2025 (nearly half of all reports linked to crypto-assets), 2,911 reports and 316 fraudulent websites flagged by the FSMA. The pace is not slowing: EUR 12.7 million already reported in the first half of 2026. Without rapid tracing, funds quickly leave exchange platforms accessible to the courts.
The investigation report
- Tracing of funds from the scam.
- Mapping of fund flows.
- Identification of platforms and counterparties.
- Priority courses of action.
- Format compatible with legal proceedings.
Price established on objective criteria, set out in the quote: transaction volume, blockchains involved, nature of the flows.
Active monitoring
Monitoring of addresses throughout the proceedings, with alerts in the event of fund movements.
Procedural support
Alongside your lawyer: pre-drafting of correspondence, requests for access to the case file, analysis of actions taken by the courts.
For whom: crypto scam victims (scams, phishing, rugpulls, boiler rooms) and their lawyer.
Pricing structure
Base fee + objective complexity
Each service relies on the same pricing structure, explicitly communicated before signature. You only pay for the core package and add-ons actually implemented.
- A base fee (analysis, drafting, validation).
- A portion linked to the objective complexity of the case file: transaction volume, blockchains involved, nature of the operations.
- A firm quote established on these objective criteria, communicated before signature.
