01 Wallet graph

Identity and custody trail.

Cluster wallets, exchanges, bridges, contracts, marketplaces, and internal movements without losing source provenance.

02 Cost evidence

Basis, disposal, fees.

Prepare technical support for acquisition cost, sale proceeds, fees, timestamps, fiat conversion references, and unresolved assumptions.

03 NFT trail

Metadata and royalties.

Track mints, buys, sales, royalties, marketplace fees, contract metadata, and transaction hashes in a reviewable package.

Important boundary: CORTEX provides technical evidence and reproducible traces. It does not provide tax advice, legal advice, filing guarantees, or automatic compliance with Agencia Tributaria requirements. A qualified tax professional should review classification and filing decisions.
