💰 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.

USDC Payments with Buyer Protection

Accept USDC cryptocurrency payments with smart contract escrow protection. 1% fees, zero chargebacks, unlimited free refunds.

unicrow

The plugin makes it easy to integrate Unicrow into a marketplace built on WooCommerce and optionally Dokan. 
It extends WooCommerce and Dokan settings to allow admins to configure its parameters
Overview
There are a few things important to understand before we get into the (very simple) setup.
<h3>About _Unicrow_</h3>
To better grasp the potential that Unicrow brings to marketplace operators, it is good to understand the protocol basics. 
* Unicrow runs on Ethereum’s Layer 2s Arbitrum One and Base and supports ETH and any ERC20 token, e.g. stablecoins like USDT or USDC 
* Each individual escrow has the following parameters: seller (supposed to receive the funds), marketplace (optional, gets a commission), arbitrator (optional, decides a dispute), and what’s the challenge (escrow) period. 
* The Buyer can release funds to the seller at any time 
* Funds can be claimed to the seller after the challenge period ends 
* The Marketplace and/or arbitrator fees will be sent out when the funds are claimed or released from the escrow. 
* Unicrow is immutable and non-custodial 
You can read more details at <a href="https://docs.unicrow.io/docs/introduction/summary" rel="nofollow ugc">docs.unicrow.io</a>. 
The <a href="https://docs.unicrow.io/docs/quick-start/basic-concepts" rel="nofollow ugc">Quick Start</a> section of our documentation website includes useful information for users. Feel free to copy&paste any of the content or refer to it in your marketplace user guides.
<h3>Supported tokens</h3>
The plugin supports ETH, USDC, and USDT on Arbitrum One network. We will extend the support for Base soon and for additional tokens based on feedback and eventually make it easier for admins to add support for any tokens. In the meantime, the admins can extend support in the source code directly (see Advanced Setup below)
Supported functionality
<h3>WooCommerce</h3>
Unicrow plugin extends Wooommerce (WC) in the following ways: 
* It is added to a list of payment methods in WC’s settings and on the checkout page 
* It adds an optional seller address attribute to product settings - this technically allows operating a multi-vendor marketplace even without Dokan, simply by adding different seller address to different products. 
* It adds a link to the transaction in Unicrow web3 app to admin emails and to the order notes.
<h3>Dokan</h3>
The plugin further adds or reuses the following to Dokan settings: 
* It uses Dokan‘s admin commission as a marketplace fee parameter in Unicrow transactions 
* It adds seller address parameter to vendor settings and if set, uses it in the transactions (in that case, setting seller address in product settings or WooCommerce Payment settings is not necessary) 
* It adds to an email sent to the vendor a note with a link to the transaction in Unicrow web3 app
Prerequisites
<h3>WordPress plugins:</h3>
<ul>
<li>WooCommerce is a required and technically sufficient pre-requisite since Unicrow plugin hooks into its functions for setting up and for payment processing.  
While WooCommerce itself doesn’t support multi-vendor setup, Unicrow extends product settings for seller address attribute. 
That means if an admin doesn’t want to complicate things with multiple sellers and an additional plugin such as Dokan, but wants to be able to process payments to different addresses for different products, the combination of WC and Unicrow allows for this.</li>
<li>(Optional) Dokan for full multi-vendor functionality.</li>
</ul>
<h3>Other/Crypto-related prerequisites for different actors:</h3>
<ul>
<li>Marketplace operator
<ul>
<li>A secure wallet able to receive fees (if applicable) on the supported network</li>
<li>An online web3 wallet to provide arbitration service loaded with a little bit bit of ETH to pay for gas costs </li>
<li>(optional) An online web3 wallet that would regularly claim payments to _sellers as a service to them (for simplification it can be done also from the Arbitrator wallet)</li>
</ul>
</li>
<li>Buyer
<ul>
<li>A web3 wallet with sufficient balance to pay the purchase and a little bit of ETH on the supported network</li>
</ul>
</li>
<li>Seller
<ul>
<li>An Ethereum address to receive the supported tokens on the supported network</li>
</ul>
</li>
</ul>
Setting Up
Follow these steps to set up Unicrow with WooCommerce and, optionally, Dokan 
1. Open WordPress Admin Console 
1. Install and activate WooCommerce, Unicrow WooCommerce plugin, and optionally Dokan 
2. Open WooCommerce → Settings → Payments and press Manage next to Unicrow 
3. Enter the values per your preference: 
 * Default Seller Address: If you plan to receive all payments to one address, paste that address here. Leave it empty if you plan to set seller address per product or (in Dokan) per vendor 
 * Marketplace Address: If you plan to collect a commission directly from Unicrow to your wallet, paste its address here. This can be a cold wallet or even an exchange address as long as it supports receiving the tokens you chose on the supported network (currently Arbitrum One TODO: add link to arbitrum guide). 
 * Marketplace Commission: Leave empty if you want the plugin to reuse Dokan commission settings or if you don’t plan to charge a commission. 
 * Challenge Period: How long a buyer can challenge the payment. After this, the seller can claim the payment. 
 * Arbitrator address: An address of a wallet account from which you will resolve disputes. The address should be funded with a little bit of ETH for gas fees and easy to access and make transactions from, e.g. a browser or even a mobile wallet. It won’t hold customer funds at any point so it can be “hot”. 
 * Arbitrator fee: Arbitrator fee in %. If the marketplace operator is an arbitrator too, can leave this at 0. 
 * Accepted tokens: Currently supporting ETH, USDT, USDC. We’d like your feedback which ones we should prioritize and will eventually let you manage a custom list (which you of course can still do by opening the plugin code and editing config.php 🙂 
4. If you use Dokan, you can set seller address per vendor in Users -> All Users -> Edit -> Unicrow Vendor Options
Advanced Setup
Please don’t hesitate to contact us at hello@unicrow.io to suggest improvements, but in the meantime if you want to add some other ERC20 token to the list or switch the plugin to support Base, you can do it by editing the plugin code using a plugin like <a href="https://wordpress.org/plugins/wpide/" rel="ugc">WPIDE</a>: 
* To add a custom ERC20 token, edit config.php 
 * In this case, we’d recommend to edit the description to reflect this too 
* To switch to Base, edit src/class-wc-gateway-unicrow.php and change <code>'chainId' => 42161,</code> to <code>8453</code>
<h3>External services</h3>
The plugin reads ETH price from Coingecko’s public API (api.coingecko.com). 
It also connects to Unicrow’s REST API to create a payment request in Unicrow’s app. Subsequently it redirects a user to the app to pay the re request and uses the provided callback url to send the user back to the confirmation page. 
The data submitted to the REST API are: 
* order price 
* order number 
* buyer, seller, marketplace, and arbitrator ETH addresses 
* marketplace and arbitrator commissions 
* escrow period
