Why BC Grading
The only grade you can prove.
Blockchain Certified
Every grade is written permanently to the Polygon blockchain. No one — including us — can alter it.
Forensic Documentation
UV imaging, 800x microscopy, AI defect mapping, and 360° capture on every single card.
No Conflict of Interest
We never buy or sell cards. Legally committed in our company articles. Your grade is never influenced.
Crystal-Clear Slab
Ultrasonically welded acrylic with laser-engraved aluminium label and NFC chip.
“Other companies tell you what grade your card got. We show you everything — then prove it on the blockchain.”
