You issue certificates as PDFs. Anyone can edit one in seconds — and when an employer wants to confirm it’s real, they email you.
A PDF certificate can be altered by anyone with a free editor — name, grade, date. AI makes it one prompt.
Employers email and call to ask “is this genuine?” — and your team answers them one by one, every week.
One viral fake with your logo on it, and trust in every certificate you’ve ever issued takes the hit.
Issue credentials anyone can verify, and collect signatures anyone can trust.
Design certificates, badges and licenses with your own fields and branding. Issue one at a time or thousands from a CSV — each cryptographically signed and anchored.
Upload multi-page PDFs, place fields exactly where they belong, and send tokenized signing links. Signers never need an account, and every document is sealed with a certificate of completion.
Every credential carries its own cryptographic proof. Here’s exactly what happens at each step.
Every credential is signed with your private key using RSA-PSS.
Only you can produce that signature.
A SHA-256 hash is computed over the exact contents.
Change one character and it’s obvious.
Fingerprints combine into a Merkle tree with one root.
A whole batch is provable at once.
The root is written to a hash-chained ledger.
Records can’t be backdated or rewritten.
Anyone re-checks the hash, signature and ledger entry.
No account, no trust in our servers.
One platform for issuing, signing and anchoring — with the controls real teams need.
Design certificates, letters and badges with your own fields, layout and branding. What you design is exactly what recipients receive and verifiers check.
Define the document types your organization issues — not just certificates.
Issue hundreds at once from a CSV, each signed and anchored.
Pluggable anchoring to EVM chains or OpenTimestamps.
Revoke a credential and verification reflects it instantly.
Download as W3C VC or Open Badges 3.0 JSON.
Send credentials and signing invites straight to inboxes.
Anyone can verify a SwanShare credential or sealed contract here — no account, no login, no calling the issuer.
Tip: issue a credential in the dashboard, then paste its verification ID here.
Trust comes from being clear about the limits. Here’s the honest breakdown.
Start free and upgrade only when you’re issuing more. Verification is always free — for you and for everyone checking your credentials.
No. Verification is public and free — anyone can check a credential with just its verification ID or the credential file, without an account and without trusting SwanShare.
Create a free account, issue a credential, and verify it yourself in under a minute.
