OnChainCert offers a free tier with 5 certificates per month. Paid plans start at $6/month for 30 certificates. We recommend the Starter plan for plumbing training.
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.

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.
