CBD & hemp brands

Crypto payments for CBD businesses — a rail with no account to freeze

Hemp is an ordinary agricultural commodity on paper and a permanent underwriting problem in practice: a legal, licensed CBD brand gets classified high-risk, quoted a premium rate, held to a rolling reserve, and terminated on a Friday with the ad spend still running. Payzum is a non-custodial, crypto-only processor: customers pay USDC or USDT straight to a wallet you control — no acquirer, no reserve, no payout schedule, no chargebacks and no balance for a risk desk to hold. Checkout, subscriptions, wholesale invoices, a QR at the storefront and one CSV for your affiliates.

QR crypto payments with no chargebacks: why a scan is final

Every payment QR looks the same to the customer — a black-and-white square on the counter. Underneath, they are not the same at all. A QR that opens a card or card-linked wallet carries the card network's dispute rights with it, which means a payment you took face to face can still be pulled back months later. A QR that carries an on-chain stablecoin payment request settles on the chain itself: once the network confirms, there is no issuer, no reason code and no window to reverse it. This is the difference between the two rails, why merchants keep getting card-present disputes they did not expect, and how a Payzum POS QR works in practice — a new code per sale, the amount already encoded, USDC or USDT landing in a wallet you control in seconds, and a refund policy that replaces the dispute process instead of losing to it.

Stablecoin clawback: a US bank just shipped a dollar it can take back

On September 9, 2026, U.S. Bank — the fifth-largest commercial bank in the country — announced it had completed a live cross-border payment with USBDC, its own dollar-backed stablecoin, on the public Stellar network. The pilot did not only test minting and redemption. It tested freezing and clawback: the ability to pull a token back out of a holder's balance without that holder's signature. Stablecoin acceptance sold merchants one core promise — the money that lands is final. A bank-issued token with clawback wired into the asset itself puts reversibility back into the money. This is an analysis of what U.S. Bank actually built, what clawback does on-chain under Stellar's CAP-35, how it differs from the freeze powers USDC and USDT already have, and the two questions a business should ask about every dollar it agrees to accept.

Food trucks & market stalls

Accept crypto payments at your food truck or market stall — no card terminal

A food truck or market stall lives where card terminals struggle: a festival field with no signal, a $12 ticket that loses 3% plus a fixed fee, a reader that needs charging, a helper on the till with no accountability, a catering deposit that comes back as a chargeback, and a cash box that has to be counted every night. With the phone you already carry, Payzum turns every sale into a fresh QR paid in stablecoins, final in seconds, with no acquirer, no hardware and nothing to charge back — settled straight to a wallet you control.

Crypto payment plugin: a drop-in checkout for your cart

"We'll add crypto next sprint" has been on the backlog for a year because the checkout is the page nobody wants to touch. A drop-in crypto payment plugin changes the unit of work: it registers Payzum as a payment method in WooCommerce, PrestaShop, Magento 2, Shopify, Shopware, OpenCart, WHMCS and 22 more platforms, creates the payment server-side with your API key, sends the buyer to a hosted checkout, and marks the order paid only when the signed webhook lands — never from the browser. Non-custodial, so the USDC arrives in a wallet you control; final, so there is no chargeback column; open source, so you can read every line before you install it. Here is what the plugin actually does, how to set it up in an afternoon, and what to do if your cart is not on the list.

PYUSDx custom stablecoins: anyone can issue a dollar now — merchants should accept one, not mint one

On September 9, 2026, PayPal, M0 and MoonPay opened PYUSDx to the public: a platform where any company can issue a branded stablecoin backed one-to-one by PayPal USD, configuring its name, symbol, reward distribution, freeze controls and reserve policy, with three issuers live and more than $100 million already processed. Read the structure and it is a wrapper on a wrapper: a custom token backed by PYUSDx, backed by PYUSD held at MoonPay Digital Assets, backed by dollar assets at Paxos. The tokens are explicitly not PayPal or Paxos products and cannot be used inside PayPal or Venmo. M0's own CEO calls the result a more fragmented stablecoin ecosystem. This analysis explains what was launched, who holds what at each layer, why every new dollar token is a new problem at the checkout, and why the right response for a merchant is not to mint a coin but to accept whichever stablecoin the customer already holds — non-custodially, into a wallet the business controls, settling in USDC or USDT.

Golf clubs

Accept crypto payments at your golf club

A golf club runs six businesses on one card terminal: membership dues that die when a card expires, tee-time deposits that come back as chargebacks when the rain does, a pro shop full of $600 drivers that fraud loves, corporate outings paid by wire a week late, foreign golfers whose cards decline at the counter, and a month-end of independent pros, caddies and greenkeeping contractors to pay. With US golf participation at a record 48 million, every one of those tickets is growing. Subscriptions for dues, payment links that lock a group booking from abroad, invoices for outings referenced to the event, a fresh QR per sale at the pro shop, halfway house and bar with a PIN per cashier, and one CSV for pros and caddies — non-custodial, final in seconds, straight to a wallet the club controls.
