DocSign

DocSign is a free e-signature app for the agreements crypto teams actually sign: SAFTs, SAFEs, token warrants, and SPV or fund documents. Send a document, collect clear e-signatures, and store everything with a full audit trail. You choose how each document is held: sent normally, end-to-end encrypted so Cryptool holds only ciphertext, or sovereign, where the PDF never leaves your device at all.

Open DocSignFree with your Cryptool account, one login across every Cryptool app.

What you can do with DocSign

  • Sign the documents crypto deals run on. SAFTs, SAFEs, token warrants, advisor and vesting agreements, SPV and fund subscription paperwork. Prepare a document, add signers, and send in minutes.
  • You choose how each document is held. Send and store it normally, encrypt it end to end in your browser so Cryptool holds only ciphertext it cannot read, or pick sovereign mode, where the PDF never leaves your computer and we keep only a fingerprint and the audit trail.
  • Clear audit trail. Every send, view, and signature is timestamped and recorded, so you can show exactly who signed what and when.
  • Everything in one place. Sent, pending, and completed documents live in one library next to the rest of your Cryptool workspace, not scattered across email threads.
  • No extra subscription. DocSign is included free with your Cryptool account. No separate signing tool to buy and no per-document fees.
  • One login, every app. The same Cryptool account signs you into DocSign, Reach, GTM, and the main platform. Sign up once and use all of them.

How DocSign works

  1. Open DocSign with your Cryptool account. Sign in with your existing Cryptool login, or create a free account in under a minute.
  2. Upload and prepare your document. Add your agreement, place signature and date fields, and choose who needs to sign.
  3. Send, sign, and store. Signers open a secure link and sign online, then everyone gets the completed copy and its timestamped audit trail.

Who it is for

  • Token projects issuing SAFTs and token warrants to investors
  • Funds and syndicates collecting subscription and SPV documents
  • Teams signing advisor, contributor, and vesting agreements

Frequently asked questions

Is DocSign free?

Yes. DocSign is included free with every Cryptool account, with no per-document fees. You sign in with your Cryptool login, and the same account works across DocSign, Reach, GTM, and the main Cryptool platform.

What kind of documents can I sign?

Any agreement you need signed, with a focus on crypto deal paperwork: SAFTs, SAFEs, token warrants, advisor and vesting agreements, and SPV or fund subscription documents. You add signature and date fields, then send for e-signature.

How is my paperwork kept private?

You choose per document at upload. The default sends and stores the file so it can go out by email, protected in transit and at rest. The encrypted option encrypts it in your browser first, using AES-256 with a key derived from your passphrase, so Cryptool stores ciphertext it cannot read (these are shared by link rather than email, because the unlock key must never travel in an email). This is often called client-side or zero-knowledge encryption.

Can I sign without Cryptool storing my document at all?

Yes. Choose sovereign mode at upload and the PDF never leaves your computer. Cryptool keeps only a SHA-256 fingerprint of the file, the signature field layout, and the timestamped audit trail, which is enough to prove what was signed and when without ever holding the document. You re-select the file from your device when you send it. Because we hold no copy, sovereign documents cannot be shared by hosted link or added to a data room.

Is there an audit trail?

Yes. DocSign records every send, view, and signature with a timestamp, so you have a clear record of who signed each document and when.

Is DocSign a free alternative to DocuSign?

Yes. DocSign gives you sending, e-signature, storage, and a timestamped audit trail free with your Cryptool account, so crypto teams can cover the same paperwork as a paid tool like DocuSign without a separate subscription. It adds client-side encryption and is built around crypto deal documents such as SAFTs, token warrants, and SPV agreements.

Can I use DocSign for a SAFT or token sale agreement?

Yes. DocSign is built for crypto deal paperwork, including SAFTs, SAFEs, token warrants, side letters, and SPV or fund subscription documents. You add signature and date fields, invite signers, and everything is encrypted so the terms stay private.

Are DocSign signatures legally binding?

DocSign records every send, view, and signature with a timestamped audit trail, the evidence most e-signature workflows rely on. Whether a given document is legally binding depends on your jurisdiction and the agreement itself, so confirm with your own counsel for regulated or high-value contracts.

How do I get started?

Open DocSign with your Cryptool account, upload your agreement, add signers and signature fields, and send. If you do not have a Cryptool account yet, you can create one free in under a minute.
