On the Result Card
The shareable face of every COA. Seal, short digest, and QR — verify without opening a PDF.
Integrity SealTM
A fingerprint for every public result.
Not a logo. Each seal is built from the certificate itself — so a copied PDF with a changed purity will not match.
- Tied to one Sample ID
- Readable by eye in 8 characters
- Optional check on the Base ledger

Anatomy
Six parts of the mark
Green tags change with the sample. The same fingerprint can be locked on Base for an independent re-check.

Hash sonar
Center of the seal
Eight bars driven by the sample’s SHA-256. Same public result → same silhouette. Different sample → different fingerprint.
- Changes with the sample
Short digest
Under the sonar
An 8-character code from the same hash. Match it on the card, COA, and verify page in seconds.
- Changes with the sample
Full orbit
Outer ring
The complete integrity hash around the rim — hard to fake by eye, easy to compare to the full record.
- Changes with the sample
Foil spectrum
Serrated edge
Notary-edge foil tinted from the hash bytes. Two seals from different samples won’t share the same ring colors.
- Privacy by design
Public fields only
What is hashed
Sample ID, stated material, purity, method, and test date — not customer names, emails, or order details.

Base ledger
On-chain proof
When published on-chain, the same fingerprint can be checked on Basescan. The mark is the claim; the ledger is independent proof.
What is sealed
Only public result fields go into the fingerprint. Change any of these and the seal no longer matches.
Sample ID
PP-YYMMDD-XXXX
Stated material
As labeled by the submitter
Purity
Area % under the method
Method
e.g. TM-HPLC-001
Test date
The day it was measured
Never sealed: customer name, email, shipping address, payment, or private lab notes.
Where you will see it
One fingerprint. Card, COA, partner site, and chain.
On the online & PDF COA
Larger seals carry the full orbit. Match the short code from the card to the official record.
On a partner storefront
A small mark on the product. Click through to public verify for that Sample ID.
In your own QA
Scan the QR or open verify. Confirm purity and method, then match the short digest by eye.
After print
A printed COA still points to the live record. If the online seal or purity does not match, treat it as suspect.
On the Base ledger
When anchored, the same hash can be checked on Basescan. The seal is what you see; the chain is independent proof.
Check a seal in under a minute
Step 1
Find the marks
Sample ID and the 8-character digest on the card, COA, or product chip.
Step 2
Open verify
Scan the QR or go to Traceabl.us and enter the Sample ID.
Step 3
Compare the result
Peptide, purity, method, and test date should match what you were shown.
Step 4
Match the digest
The short code — and the sonar, when you can see it — should match the online record.
Step 5
Optional: check the chain
If on-chain is listed, open Basescan and confirm the same hash.
