Sign Agreements.
Prove It Forever.

Blockchain-verified signing — with or without uploading a document. Record agreements, prove consent, and verify signatures permanently.

How It Works

1

Create

Upload a file, write an agreement, use a template, or create a blind sign

2

Sign

Each signer receives a link to review and sign

3

Seal

Once all parties sign, the proof is stored on blockchain

4

Verify

Anyone can verify the document anytime via QR code or link

Sign From Anywhere

No need to meet face-to-face. All parties sign online from wherever they are — different offices, cities, or countries.

No Physical Meeting Needed

Each party receives their own secure signing link. Review, sign, and submit from any device — phone, tablet, or computer.

Sign on Your Own Time

No scheduling conflicts. Each signer signs when it's convenient for them — the document stays open until everyone has signed.

Every Signature Is Verified

Each signature captures the signer's IP address, timestamp, and device details — then seals it all with tamper-proof blockchain verification.

Why Blockchain Verification?

Tamper-Proof

Once stored on the blockchain, the record cannot be altered by anyone — not even us.

Publicly Verifiable

Anyone can verify a document's authenticity — no account needed, no software required.

Permanent Record

Blockchain records exist forever. Your proof of signing never expires or disappears.
