Signatures your opposing counsel can verify — without calling you.
Every signature is anchored to a public blockchain. Every certificate includes a hash that anyone can check. Your documents prove themselves.
Why it matters
A certificate should be a proof, not a promise.
Most e-signature platforms issue a Certificate of Completion that says “trust us — this happened.” If their servers go down, their logs get subpoenaed, or the company ceases to exist, your certificate is worth whatever they say it is.
Zdottedline anchors every sealed envelope to a public blockchain. The hash is independently verifiable — by you, by opposing counsel, by a court — with or without Zdottedline online.
