Non-custodial, crypto-only payments — explained for the operators and developers who actually run the money. Pain, mechanics, and how Payzum solves it.
Install an open-source gateway, paste two keys and enable it for Visual Form Builder forms, and donors can give USDC or USDT on any GiveWP form. A signed webhook completes the donation, GiveWP sends its usual receipt, and the gift settles to your organization's own wallet. Here are six checks for any GiveWP crypto gateway, the Payzum plugin set up step by step, what happens at each payment status, and what it deliberately doesn't do, recurring gifts included.
Yes, and Sylius too. Payzum publishes open-source integrations for all four headless frameworks, each built on the framework's own payment extension point: a Medusa payment provider, a Saleor payment app, a Vendure payment handler and a Sylius 2 gateway. The buyer pays USDC or USDT on a hosted checkout, a signed webhook marks the order paid, and the money settles to your own wallet. Here is how each one hooks into checkout, six checks for any crypto plugin, and the setup step by step.
On October 1, 2026, Brazil's Resolution BCB 561 took effect: eFX cross-border payment providers can no longer settle with partners abroad in stablecoins or any other crypto. The same night, Resolution BCB 591 made transfers of US$10,000 or more to or from self-custodied wallets reportable to COAF. This analysis lays out Brazil's crypto rule calendar through May 2027, explains why the central bank took stablecoins out of the plumbing rather than out of people's wallets, and maps the three routes a business selling to Brazilians now has, including where non-custodial stablecoin acceptance fits and where it doesn't.
Install an open-source gateway module, paste two keys, and clients can pay any WHMCS invoice in USDC or USDT, renewals included. A signed webhook marks the invoice paid and WHMCS runs its usual automation; the money settles to your own wallet. Here are six checks for any WHMCS crypto module, the Payzum module set up step by step, how renewals and prepaid credit work when crypto can't be charged automatically, and the sibling modules for Blesta, HostBill and ClientExec.
On September 10, 2026 Circle announced it is discontinuing USDC and its legacy cross-chain protocol, CCTP V1, on Noble, the Cosmos chain built as USDC's home in the IBC ecosystem. Minting through Circle Mint stops October 13, CCTP V1 is paused December 1, and the Noble USDC contract is paused January 12, 2027, with a manual redemption portal after that. This analysis sets the USDC Noble deprecation next to Circle's exit from Tron and Tether's wind-down of five legacy chains. It explains what a chain retirement does to a business that holds the coin, gives five checks for choosing the networks you accept stablecoins on, and shows how non-custodial settlement puts you in control of where the money sits.
Yes. Payzum's open-source PrestaShop module takes USDC and USDT on a hosted checkout and settles to a wallet you control. PrestaShop creates the order only when a signed webhook confirms the payment at the cart's exact total. Here are six checks for any PrestaShop crypto module, then version 1.2.0 set up step by step: install, settings, what happens at each payment status, and which PrestaShop versions it really runs on.
On October 1, 2026 the core of Florida's payment stablecoin law took effect: CS/CS/HB 175, now Chapter 2026-176, Laws of Florida, which creates Part V of chapter 560 and requires an Office of Financial Regulation license (or an exemption) to act as a state-qualified payment stablecoin issuer. The same day it was signed, June 26, the Governor also approved SB 1568, the Florida Stablecoin Pilot Program, which lets the Department of Financial Services accept designated stablecoins for fees and convert them to dollars. This analysis reads the statute for what it means to a business that gets paid in stablecoins: the license covers issuing, redeeming and reserves, not acceptance; self-custody and person-to-person transfers sit outside the part; the real touchpoint is the off-ramp, where money services businesses now record payment stablecoin transactions above $10,000. It turns the state's own pilot into a five-line acceptance policy, walks through Florida use cases from Miami counters to Doral exporters, and shows where non-custodial settlement fits.
The right Magento 2 crypto payment plugin settles to a wallet you control, invoices orders only from a signed webhook, survives production mode and has code you can read. Here are six checks for any module, then Payzum's open-source module for Magento 2.4 and Adobe Commerce, set up step by step: install, the admin settings, the order-status map, and what it does not cover.
On September 28, 2026 the minority staff of the Senate Permanent Subcommittee on Investigations published Tethered to Terrorism, a 28-page preliminary report finding that 84% of 846 Iran-linked wallets designated by OFAC or Israel's NBCTF between June 2021 and August 2026 transacted exclusively or nearly exclusively in USDT. Its sharpest finding is a timing gap: of 39 addresses Israel flagged in June 2023, Tether froze five, and the rest moved $34.6 million over nine months. Tether points to nearly $550 million in Iran-linked freezes in 2026. This analysis reads the numbers carefully (a selected sample, two very different lists, no charges), explains how the GENIUS Act's foreign-issuer clause (12 U.S.C. § 5907) turns lawful-order compliance into the test for whether US platforms may keep offering a token, and maps the three practical exposures for a merchant that accepts USDT: issuer freezes, off-ramp holds and platform access. It closes with a seven-step checklist, what changes for stores, counters, exporters, payers and API sellers, and how non-custodial settlement to your own wallet keeps the processor out of the freeze chain.
