Plain answers about e-signing — whether it is legally binding, how to sign and verify a document, and what it costs.
An electronic signature is your intent to agree to a document, captured electronically — a typed or drawn signature, a click, or a biometric confirmation — and bound to the record you signed. SignaTrust is an e-signature platform: you upload a document, add signers, and each person signs from a browser or phone. Every completed signature is also anchored to a public blockchain so it can be verified later by anyone.
In the United States, electronic signatures carry the same legal weight as handwritten ones under the ESIGN Act (2000) and UETA, and in the EU under eIDAS — provided four conditions are met: the signer intended to sign, consented to do business electronically, the signature is attributable to that person, and the record is retained. SignaTrust captures each: a signing ceremony for intent, an explicit ESIGN consent step, tiered identity verification for attribution, and a retained evidence bundle. Whether a specific document is enforceable still depends on the underlying agreement and your jurisdiction.
An electronic signature is the legal act of agreeing to a document electronically. A digital signature is a cryptographic technique — public-key math that detects whether a record has changed. The two are often confused because a sound e-signature platform uses digital-signature techniques underneath. SignaTrust does: every signed document is hashed, the hash is anchored to the Solana blockchain, and a qualified RFC 3161 timestamp is applied, so any later change to the file breaks the cryptographic chain.
You receive a link by email or text, open it in any browser or on your phone, review the document, place your signature, and confirm. No account or app download is required to sign. The sender receives the completed PDF plus a sealed evidence bundle, and both parties can verify the signature independently afterward.
Each SignaTrust signature is bound to three independent witnesses: a public Solana blockchain anchor, a qualified RFC 3161 timestamp from an independent authority, and a hash-chained audit log where any tampering breaks the chain. These travel together in a self-authenticating evidence bundle that anyone can verify offline, without contacting SignaTrust. The chain proves the document is unaltered and when it was signed; who signed is established by the identity tier chosen for the signing. Admissibility itself is decided by the court, but the evidence is built to stand on its own.
SignaTrust uses flat monthly tiers, not per-seat pricing: Free for 10 envelopes a month, Pro Lite at $15 for 50, Professional at $29 for 150, and Business at $99 for 500 with a HIPAA Business Associate Agreement. An envelope is one signing request, regardless of how many signers it has. Because pricing is flat rather than per-user, adding signers or recipients does not increase the cost.
The Business tier includes a HIPAA Business Associate Agreement, and the zero-custody design keeps your documents in your own storage rather than a vendor database. For higher-assurance signings — healthcare consent, real estate, or financial agreements — you can require one-time-passcode or biometric (passkey) identity verification before a signer can complete. A SOC 2 audit is in progress.
Three differences. First, pricing is a flat monthly fee, not per-seat, so cost does not climb as you add users. Second, every signature is anchored to a public blockchain and time-stamped by an independent authority, so the proof does not depend on SignaTrust staying online — anyone can verify it offline. Third, your documents stay in your own storage (zero-custody), and an AI assistant reviews contracts for risky clauses before you sign. Legacy per-seat platforms keep the audit trail in their own database and charge by the user.
Yes. Open the public verification page at signatrust.io/verify and upload the signed PDF or its evidence bundle. The check recomputes the document hash, looks it up on the Solana blockchain, and confirms the timestamp and audit chain — all without a login. Verification works even if you are not a SignaTrust customer.
