Your contracts are serious. Your home screen doesn't have to be. One tap in Settings and HashSign wears whatever icon you like. Same SHA-384 digest underneath. Sorry @elonmusk, it was @grok ‘s idea.

Replying to @Techstars
HashSign is going as a notary tonight. Fake mustache, real SHA-384 digest. Trick or treat: hand us a contract and we'll unmask the auto-renewal hiding on page 8 in a ghost costume. Free to start. Scary clauses not included.

We plugged Grok Bot into HashSign. It reads contracts, flags the traps, asks before anything sensitive. You pick the leash: Observer never signs, Co-Pilot waits for your tap, Auto-Sign stays in your rules. @grok honest opinion: good idea or terrifying? hashsign.app

You already agreed to this. Page 7, Section 3: it auto-renews for another full year. HashSign AI's Legal Risk Inspector flags auto-renewals, one-sided indemnity and low liability caps in plain English, before you sign. Then fix it with the other party in encrypted in-app chat. Read the fine print before it reads you.

Draft. Inspect. Delegate. Close. Store. 📄🤖 HashSign 1.2.2 covers the whole contract lifecycle in five taps. Draft it with AI, inspect it for risk, hand it to your agent, close it in a Deal Room, vault it. Nothing signs until you allow it. Live now on @AppStore and @GooglePlay. Yes, finally, we both waited.

Your AI agent can sign contracts now. Relax, it has a spending limit. Connect Grok or Muse in HashSign 1.2.2 and pick a mode: Observer, Co-Pilot, or Auto-Sign inside your rule, risk and dollar caps. Every signature anchored on @hedera. hashsign.app #AIAgents #HBAR

Other e-sign apps: "sign here." HashSign 1.1.4 drafts the contract, flags the risky clauses, opens a Deal Room, messages the other side (encrypted) and anchors proof to a public ledger in milliseconds. Most advanced document utility app in the world. Texas-built. hashsign.app #AI #Hedera On @AppStore + @GooglePlay: hashsign #AI #LegalTech #HBAR #Web3

Your AI agents can pay. Then a contract shows up, and the whole workflow stalls waiting on a human with a pen. The HashSign API takes it down to three calls: 1️⃣ Upload 2️⃣ Sign 3️⃣ Verify 🔑 Scoped API keys, so agents never hold private signing keys 🧮 SHA-256 computed locally, so only the digest is uploaded 📜 Every sign request lands in an audit log ⛓️ Hash anchored on Hedera Consensus Service 🛡️ Optional post-quantum hybrid signatures (ECDSA P-256 + ML-DSA-65) pip install hashsign-python Docs and keys at hashsign.io (link in bio) Texas-built.

Ever signed a contract you never fully read? 👀 HashSign's AI reviews every clause and flags the risky ones in plain English, like low liability caps, sneaky auto-renewals, and one-sided indemnity. You can message the other party right in the app, sign, and then seal the document's fingerprint on @hedera so it can't be changed. Review, chat, sign, and verify, all in one app. 📲 hashsign.app 🇺🇸 Built in Texas. Veteran owned.
