HOW IT WORKS
Three steps.
Zero trust required.
Buyer locks funds
Payment sits in the SquareChain vault. Both parties can see it. No one can touch it until agreed conditions are met.
Seller delivers
Work is done. Goods are shipped. Milestones are hit. The deal moves forward on terms both sides agreed upfront.
Funds release automatically
Once confirmed, the seller is paid instantly. No waiting. No manual approval. No disputes. Just done.
FOR EVERYONE
Built for any deal where money changes hands.
Freelancers & Contractors
Get paid for every job, guaranteed. No more chasing invoices.
Small & Medium Businesses
Protect supplier payments and contracts without expensive legal overhead.
Real Estate & Consultants
Hold deposits and milestone payments securely through long-form deals.
Crypto OTC Traders
High-value peer-to-peer trades with institutional-grade protection.
Online Marketplaces
Every buyer-seller transaction protected. Both sides. Always.
Enterprise & Legal
Multi-party settlements with full audit trails and automated release.
USE CASES
Every deal.
Covered.
A client hires a developer for a $12,000 app build.
Instead of paying upfront — risky for the client — or working for free — risky for the dev — SquareChain splits it: 30% at design approval, 40% at beta, 30% at final delivery. Both sides protected.
VERIFYMARK
Physical goods.
On-chain proof.
VerifyMark is SquareChain's product authentication layer. Manufacturers register NFC tags; buyers verify before release — ideal for luxury, pharma, and high-value goods in AutoSquare deals.
Open VerifyMark dashboardNFC-bound identity
Each physical product is tied to an immutable on-chain record via its NFC UID — no duplicate tags, no copy-paste certificates.
Instant verification
Buyers scan a tag to confirm authenticity, batch, and manufacturer before they pay — VerifyMark feeds directly into SquareChain escrows.
Tamper reporting
Broken or cloned tags can be reported on-chain. Tampered products are flagged permanently in the registry.
Immutable hash anchor
Publish transaction hashes on Arbitrum. Anyone can verify an institution published a specific record without trusting a private database.
Institutional audit trail
Banks, exchanges, and payment processors anchor settlement proofs for regulators and counterparties.
Public verification
Proof IDs are deterministic on-chain. Share a proof link — verifiers compare off-chain documents to the published hash.
LEDGERPROOF
Settlement proofs
anyone can check.
LedgerProof lets institutions publish cryptographic hashes of off-chain transactions to the SquareChain Diamond — a permanent, verifiable audit layer alongside escrows and VerifyMark.

Your Square Score tracks every deal you close. The more successful, dispute-free transactions you complete, the higher your score rises. It's your financial reputation — on-chain.
A counterparty with a 961 score is not the same as one with a 712. Now you can see the difference before you sign anything.

What people say
when deals close.
“First time in 6 years I haven't had to chase a single invoice. The client funded the escrow before I started. That changed everything.
“We replaced our entire deposit management process. Legal fees dropped. Client trust went up. SquareChain did in one afternoon what lawyers took months to set up.
“I've done $400k in OTC trades through SquareChain this year. Not one dispute. GuardianSquare is the only way I'll do high-value deals now.
Don't say "trust me, I'll pay."
Say "let's Square it."
The standard for verifiable trust.
