<h3>Source code and build</h3>
This plugin includes minified frontend bundles: 
– assets/js/icpay-embed.min.js (ICPay widget) 
– assets/js/wc/index.umd.js (optional WalletConnect adapter UMD for the widget)
Public source (maintained and human-readable): 
– Widget: https://github.com/icpay/icpay-widget (MIT) 
– SDK: https://github.com/icpay/icpay-sdk (MIT) 
– WalletConnect (optional adapter runtime): https://github.com/WalletConnect/walletconnect-monorepo
Exact mapping of distributed files to source: 
– assets/js/icpay-embed.min.js → Built from https://github.com/icpay/icpay-widget (package “@ic-pay/icpay-widget”). 
 – Primary sources live under /src in that repository. 
 – Build target is the IIFE embed bundle at /dist/index.embed.js, which is copied and renamed to icpay-embed.min.js for this plugin distribution. 
 – Example tagged release used: see icpay-widget releases matching this plugin version. Repository includes full TS sources and sourcemaps. 
– assets/js/wc/index.umd.js → Built from https://github.com/icpay/icpay-widget at /src/index.umd.js (WalletConnect adapter UMD) and copied to /dist/wc/index.umd.js by the build script.
Build instructions (reproducible): 
1) Clone https://github.com/icpay/icpay-widget 
2) Install dependencies (pnpm, yarn, or npm): 
 – pnpm install 
3) Build the library (produces ESM, IIFE embed, and UMD adapter): 
 – pnpm build:embed 
 – The script also copies the WalletConnect UMD adapter to dist/wc/index.umd.js 
4) Copy artifacts into this plugin: 
 – dist/index.embed.js → instant-crypto-payments-for-woocommerce/assets/js/icpay-embed.min.js 
 – dist/index.embed.js.map (optional, recommended) → instant-crypto-payments-for-woocommerce/assets/js/icpay-embed.min.js.map 
 – dist/wc/index.umd.js → instant-crypto-payments-for-woocommerce/assets/js/wc/index.umd.js
Notes: 
– The widget depends on “@ic-pay/icpay-sdk”, which is fully open source at https://github.com/icpay/icpay-sdk; the SDK sources are not vendored into this plugin but are bundled into the distributed widget file as part of the upstream open-source build. 
– If you prefer, you may vendor the unminified files from icpay-widget/dist instead; WordPress.org accepts either shipping unminified sources with the plugin or providing public, maintained source links (as above).
<h3>External services</h3>
This plugin connects to the ICPay service operated by ICPay, Ltd. to process payments. Details below list what is used, when, what data is sent, and links to each provider’s terms and privacy policies.
1) ICPay API (icpay.org, api.icpay.org) — operated by ICPay, Ltd. 
– What/why: Create and manage a payment and receive payment status updates. 
– When: When rendering the pay button (client-side widget load) and when receiving payment webhooks or running order payment verification. 
– Data sent: Order amount (in store currency; sent with optional fiat_currency when store is not USD), selected crypto asset, and order metadata (e.g., orderId). Webhook payloads contain payment status updates for the order. 
– Terms: https://icpay.org/terms 
– Privacy: https://icpay.org/privacy
<h3>Additional third-party services used by the widget (optional)</h3>
2) WalletConnect RPC (rpc.walletconnect.org) — provided by WalletConnect 
– What/why: Facilitate mobile wallet connections via WalletConnect. 
– When: Only if the WalletConnect adapter is enabled AND the shopper chooses WalletConnect. 
– Data sent: Wallet session metadata and JSON-RPC requests needed to complete a payment. 
– Terms: https://walletconnect.com/terms 
– Privacy: https://walletconnect.com/privacy
3) Wallet vendor websites and app deeplinks — shown only if the WalletConnect adapter is enabled and the shopper chooses a wallet. Navigation happens only on explicit user action; the plugin does not send data to these vendors automatically. 
– Phantom: https://phantom.app — Terms: https://phantom.app/terms — Privacy: https://phantom.app/privacy 
– Solflare: https://solflare.com — Terms: https://solflare.com/terms-of-use — Privacy: https://solflare.com/privacy-policy 
– Coinbase: https://go.cb-w.com (redirect), https://www.coinbase.com — Terms: https://www.coinbase.com/legal/user_agreement — Privacy: https://www.coinbase.com/legal/privacy 
– Binance: https://app.binance.com, https://www.binance.com — Terms: https://www.binance.com/en/terms — Privacy: https://www.binance.com/en/privacy
4) On-ramp provider (optional and disabled in this plugin build) 
– The bundled WalletConnect adapter contains an optional on-ramp link for “Meld” (domain: https://meldcrypto.com). In this plugin distribution, on-ramp is disabled by default; no requests are made to this provider. 
– When: Only if a developer explicitly enables on-ramp in the widget configuration and the shopper chooses to open it. 
– Data sent: None by default in this plugin. If enabled by a developer, the provider’s own site and terms will apply. 
– Vendor site: https://meldcrypto.com (please refer to the vendor site for terms and privacy)
<h3>Remote assets and CDN fallbacks</h3>
<ul>
<li>This plugin bundles all primary JS/CSS/images locally and does not offload required assets to remote CDNs.</li>
<li>The optional WalletConnect adapter may reference external vendor logos or pages provided by those vendors. We ship local icons where possible; any navigation to vendor sites occurs only when the shopper explicitly chooses that wallet. No plugin settings or secrets are transmitted by simply rendering the checkout page.</li>
</ul>

<h3>What are “Web3 Payments”?</h3>
Building on the idea that “Web3” is the next generation of a blockchain-based and therefore decentralized Internet, “Web3 payments” are a new type of direct wallet-to-wallet payments that you can receive directly into your own crypto wallet. 
Besides being decentralized and peer-to-peer, they are also characterized by being “permissionless” and not requiring you to trust (“trustless”) in centralized entities such as intermediaries. 
Furthermore, Web3 payments are censorship-resistant. Read more: <a href="https://depay.com/web3-payments" rel="nofollow ugc">What are Web3 Payments?</a>.
<h3>How does “on-the-fly” conversion work?</h3>
<ul>
<li>You configure which tokens you want to receive (e.g. USDT, BUSD) per blockchain</li>
<li>Website visitors can make payments with any token they currently have in their wallets (e.g. ETH or any other token)</li>
<li>DePay’s smart contracts auto-converts the payment into the tokens you have configured to be received.</li>
<li>The payments always arrive directly in your own wallet.</li>
</ul>
