Clarity in the crypto world
Trace — declare · repatriate · investigate
KlearChain supports crypto-asset holders in Belgium. Our core business: transforming your crypto transaction history into a clear and comprehensive case file that serves as proof for your bank, the Belgian tax authorities or the courts.
A tailored service, adapted to the Belgian authorities
Off-the-shelf software tools produce automated reports without human oversight, legal validation or precise tax characterisation. In contrast, our team personally supports every case file, from the simplest to the most complex.
Our three partners draw on their experience in the Belgian financial, political and legal sectors. They leverage their expertise and network to bring your case file to a successful conclusion, including the most complex ones (significant wealth, fragmented investment history, complex scams, heightened banking requirements…).
An increasingly demanding crypto world
2026
Bank repatriation
MiCA (end of 2024) followed by DAC8: from 2026, exchange platforms will transmit your transaction data to the Belgian tax authorities. In parallel, your bank must be able to verify the source of funds it accepts, its own specific obligation, with no mandated format or provider. An Excel spreadsheet is no longer enough. This is where KlearChain comes in.
10%
Tax return
Since 1 January 2026, no crypto capital gain escapes tax in Belgium. Every gain falls under a regime: 10% for normal management of private assets, 33% for speculation, progressive rates for a professional activity. The question is which one applies to each of your transactions. KlearChain qualifies your transactions and prepares your tax return.
€38.3M
Scams and disputes
Lost to investment fraud in Belgium in 2025, nearly half of reports linked to cryptos (FSMA). KlearChain acts quickly to trace your funds and give the courts the means to act.

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).

Why KlearChain
What sets us apart
Where the market offers self-service SaaS tools or international recovery platforms, we offer tailor-made, human, Belgian support. A contact person is available at every step: collection, analysis, delivery, and attendance at bank or court meetings if necessary. The client is never left alone facing the tool.
Our commitments
