Frequently Asked Questions

Common questions about blockchain certificates for construction companies.

How does blockchain verification work for construction companies?
When you issue a certificate through OnChainCert, we create a unique cryptographic hash of the certificate data and record it on the Polygon blockchain. This creates an immutable, tamper-proof record that anyone can verify instantly using the certificate ID.
How much does it cost?
OnChainCert offers a free tier with 5 certificates per month. Paid plans start at $6/month for 30 certificates. We recommend the Professional plan for construction companies.
Can employers verify certificates for free?
Yes! Verification is completely free and requires no account. Anyone with a certificate ID can instantly verify its authenticity on our verification page.
What blockchain do you use?
We use Polygon, a leading Layer 2 Ethereum blockchain known for its speed, low costs, and environmental sustainability. Polygon is carbon-neutral and processes thousands of transactions per second.
