A token can move across chains, but its acquisition history should never lose continuity.

Every bridge introduces another layer of complexity. Oncobira is designed to keep cost-basis records connected, making cross-chain asset tracking more consistent and verifiable.

What happens to your acquisition history when an asset moves between blockchains?

Oncobira introduces a private cross-chain cost-basis passport that travels with every acquisition lot.

One record. Multiple chains. Continuous history.

Financial transparency should not require exposing your entire portfolio.

Oncobira focuses on selective verification, allowing tax tools to confirm cost-basis continuity without accessing complete wallet histories.

Privacy and verifiability should work together.
