💰 SPECIAL OFFER: 1% transaction fee locked in FOREVER for first 20 merchants
<h4>The Crypto Commerce Opportunity</h4>
$9.7 trillion in crypto changes hands monthly, but only 0.003% is ecommerce. Compare that to traditional finance where 0.4% is ecommerce – that’s 130x more adoption.
Why the gap? Crypto holders want to spend, but lack buyer protection. This plugin solves that problem with smart contract escrow, letting you tap into trillions in purchasing power that competitors ignore.
<h4>What Makes This Different</h4>
Eliminate Chargeback Fraud While Keeping Buyer Confidence: 
Traditional processors: You face chargeback fraud ($15-100 per incident) and arbitrary account freezes. 
USDC Payments: Crypto payments are final, but escrow protection gives buyers confidence. Fair automated dispute negotiation replaces chargebacks. Zero fees for unlimited refunds.
True Cost Savings: 
– 1% flat fee (30¢ minimum) – locked forever for first 20 merchants 
– Zero gas fees – we cover all blockchain transaction costs 
– No FIAT exchange fees – keep more of what you earn 
– Unlimited free refunds – no refund fees, no chargeback limits, no penalties 
– Compare: Traditional processors charge 2.9% + 30¢ + refund fees + chargeback fees
Example on $100 order: 
Traditional: $3.20 + potential $15-100 chargeback = $3.20-$103.20 
USDC Payments: $1.00 (no chargebacks possible)
Blockchain-Enforced Security: 
Smart contract code is immutable and publicly verifiable. It restricts beneficiaries to exactly two addresses: yours (seller) and buyer’s (for refunds only). No one else – not even us – can access those funds. This is enforced by the blockchain itself, not by trust.
Speed & Privacy: 
– 3 minutes to install and configure 
– 3 minutes for buyers to complete checkout (2 clicks to pay) 
– No KYC for customers – they can remain anonymous 
– No KYB for merchants – self-setup in 3 minutes 
– You own your account – true peer-to-peer, no intermediary
<h4>Key Features</h4>
<ul>
<li>1% Transaction Fee Forever – First 20 merchants get lifetime 1% rate (covers gas fees)</li>
<li>Smart Contract Escrow – Immutable code ensures funds only go to seller or buyer (refunds)</li>
<li>Automated Dispute Negotiation – Fair resolution with messaging and refund proposals</li>
<li>Unlimited Free Refunds – No refund fees, no chargeback limits, no penalties</li>
<li>True Peer-to-Peer – No intermediary can access funds, direct merchant-to-buyer contracts</li>
<li>Privacy First – No KYC/KYB required, both parties can remain anonymous</li>
<li>2-Click Payments – Lightning-fast checkout (3 min total transaction time)</li>
<li>Seamless Integration – Works with existing WooCommerce checkout flow</li>
<li>Mobile-Friendly – Responsive payment interface on all devices</li>
<li>Real-time Updates – Automatic order status updates via webhooks</li>
<li>Admin Dashboard – Complete visibility into payment contracts and statuses</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Customer Checkout – Customer selects USDC payment at checkout</li>
<li>Escrow Creation – Smart contract creates secure escrow holding funds</li>
<li>Order Fulfillment – You ship order and provide tracking</li>
<li>Automatic Payment – Funds release to you at payout date/time unless dispute raised</li>
<li>Dispute Protection – If issues arise, automated negotiation handles fair resolution</li>
</ol>
No chargebacks. No fraud. No refund limits. Just secure, low-fee payments.
<h4>How Escrow Protection Works</h4>
When a customer pays, funds lock in a smart contract (not sent directly to you). You set a payout date/time (e.g., 14 days after purchase).
If everything goes smoothly: Funds automatically release to you at payout date.
If there’s a problem: Customer raises a dispute before payout, freezing funds until both parties negotiate refund percentage (0-100%) through automated system. Both send messages and proposals. When you agree, funds distribute accordingly. No fees, no limits.
If customer is unresponsive: After timeout period (default 72 hours), you can claim the funds.
Unlike traditional processors where the company can freeze or reverse payments, these smart contracts are peer-to-peer – only you and your customer control the outcome.
<h4>What is USDC?</h4>
USDC (USD Coin) is a stablecoin where 1 USDC = $1 USD. Each token is backed by real US dollars in reserve, making it stable for commerce. Unlike Bitcoin or Ethereum, USDC doesn’t fluctuate – it’s digital dollars on the blockchain.
