Non-custodial, crypto-only payments — explained for the operators and developers who actually run the money. Pain, mechanics, and how Payzum solves it.
Install Payzum's open-source WooCommerce plugin, paste an API key and webhook secret, and connect the IPN URL. Buyers then pay USDC or USDT on a hosted checkout, and a signed webhook marks the order paid. Here is the full setup, every setting on the screen, which order status you will see at each step, block checkout and HPOS support, and what the plugin does not do.
On September 28, 2026, Citi and Coinbase expanded their partnership: Citi's institutional clients can accept stablecoin payments at checkout through Spring by Citi, the bank's payment acceptance platform, with Coinbase Payments powering acceptance. Coinbase converts the stablecoins into fiat and Citi settles as bank of record, so the merchant never holds, custodies or manages a token. The same release launched the opposite pipe — Coinbase Virtual Accounts, powered by Citi, convert incoming fiat into stablecoins. This analysis reads the design as a new tender inside an acquirer rather than a new rail, lists what survives the conversion (reach, balance-sheet simplicity) and what doesn't (speed, finality, the token itself), places it in a month in which five banks put stablecoins everywhere except a merchant's wallet, and offers a decision guide on where the conversion should happen. Then it shows the non-custodial alternative that exists today: settlement directly into a wallet the merchant controls, with optional auto-convert to USDC or USDT.
Yes — 29 of them. Payzum publishes its official integrations for WooCommerce, Magento 2, PrestaShop, Shopware 6, Shopify, WHMCS, GiveWP, Medusa, Saleor and 20 more platforms as public repositories under MIT, GPL or OSL licenses. Here is the complete list by category, with the license and install path for each, why open source matters for the one plugin that decides an order is paid, and a 15-minute checklist to audit how the webhook is verified and where the funds go before you install it.
Meta launched Muse on September 8, 2026 with Stripe's Link wallet built in. Within two weeks it was the top app in the US App Store, Amazon had blocked it, and Shopify and PayPal had opened their merchants to it. Every Muse purchase still runs on card and wallet rules. What letting shopping agents in gets you, what it doesn't change, and the channels a merchant can own directly.
A fresh QR per sale at the counter on release day, expiring payment links for draw winners and Instagram or WhatsApp holds, hosted checkout or a drop-in plugin for the web store, and stablecoin payouts to consignors and walk-in sellers — every payment final in seconds, settled to a wallet your store controls. No stolen-card grails, no “it was fake” chargebacks months after the pair shipped.
On September 24, 2026 attackers drained about $387.5 million from Bitget's hot and warm wallets by spoofing transaction data inside its backend. Withdrawals paused and restart in phases through October 2 — USDC and fiat last — while deposits and trading stayed open. Bitget says balances are intact and its protection fund covers the loss. What that means for any business whose customers pay into an exchange deposit address, and how to move crypto revenue to a wallet you control.
A fresh QR at the counter for e-bikes, parts and workshop tickets, payment links for phone and web orders, expiring invoices for special-order and custom-build deposits, rentals and guided rides paid from abroad, and subscriptions for service plans — every payment final in seconds, settled to a wallet your shop controls. No stolen-card e-bike orders, no chargebacks on a frame built to someone's size.
On September 22, 2026 Coinbase for Agents added US stocks and x402 payments, so trading agents inside ChatGPT, Claude, Perplexity and Grok can pay a few cents per call for market data from their owner's USDC balance. What that means for anyone who sells financial data, analytics or models — and how to price, list and serve an agent buyer without rebuilding your API.
Expiring invoices for the design fee and every procurement proposal, payment links for clients furnishing a second home from abroad, e-design packages at a hosted checkout, a QR in the showroom, and stablecoin payouts to installers and workrooms — every payment final in seconds, settled to a wallet your studio controls. No card percentage on pass-through purchases, no deposit disputed after the custom sofa is already on order.
