In 2026, the fintech landscape is shifting from speculation to production. For hosting providers, VPN services, and digital agencies using WHMCS, the question is no longer if you should accept cryptocurrency, but how efficiently you can do it. With stablecoins becoming the "Internet’s dollar" for cross-border flows, integrating a robust payment gateway is essential for maintaining a competitive edge in the EU and global markets.
One of the most seamless ways to bridge the gap between traditional billing and the crypto economy is through the INXY Payment Gateway. This guide provides a detailed walkthrough for setting up the INXY module on your WHMCS platform.
1. Why Crypto for WHMCS in 2026?
Integrating crypto payments into your billing system offers several strategic advantages:
Lower Fees: Traditional processors often charge 2–4% for international payments, while gateways like INXY provide more cost-effective alternatives.
Chargeback Protection: Blockchain transactions are immutable; once confirmed, they cannot be reversed by the sender, eliminating the administrative burden of fraudulent chargebacks.
Global Reach: Crypto allows you to accept payments from customers in regions with restrictive banking or unstable local currencies without multi-day delays.
2. System Requirements
Before installation, ensure your environment meets the following criteria for the INXY module (Version 1.0.3):
Location: Go to Merchant settings → API in the INXY dashboard and paste the URL.
5. Advanced Matching and Underpayment Rules
Crypto transactions can sometimes result in minor amount differences due to network fees. INXY handles this through the config.php file:
Amount Deviation: By default, the module accepts payments within 1% of the requested amount. For WHMCS, it is recommended to set 'amount_deviation_percentage' = 49 to reduce unnecessary top-up attempts and align with WHMCS's partial payment flow.
Time Window: Payments must arrive within 2 hours in production (30 minutes in Sandbox) to be automatically matched.

Cross-Border B2B Payments With Stablecoins: The 2026 Guide to Faster, Cheaper Settlement
This guide explains how cross-border stablecoin payments actually work, how they compare to SWIFT, where they make the most sense, and what it takes to start accepting them.
For most businesses, sending money across borders still feels like it did a decade ago: slow, opaque, and expensive. Cross-border crypto payments built on stablecoins are changing that. Instead of routing an international crypto payment through a chain of correspondent banks, a stablecoin transfer settles directly on a blockchain in seconds, for a fraction of the cost. In 2026 this is no longer a fringe experiment — it is one of the fastest-growing segments in business payments, and the data behind it is hard to ignore.
This guide explains how cross-border stablecoin payments actually work, how they compare to SWIFT, where they make the most sense, and what it takes to start accepting them.
Why cross-border crypto payments are replacing the old rails
The traditional system was never designed for the speed of modern commerce. It was designed for banks talking to banks.
The hidden cost of SWIFT and correspondent banking
A typical international wire passes through two to four intermediary banks before it reaches the recipient. Each one takes a cut and adds a delay. The result is well known to any finance team: wire fees of roughly $40–$80 per transaction, settlement times of one to three business days (longer across exotic corridors), and almost no visibility into where the money is at any given moment. Add unfavorable FX spreads and the all-in cost of moving money internationally can quietly erode margins on every cross-border deal.
For a company paying dozens or hundreds of overseas suppliers, contractors, or partners each month, that friction compounds fast.
What changed in 2026
Stablecoins — blockchain tokens pegged 1:1 to a fiat currency such as the US dollar — turned out to be an almost perfect fit for this problem. They hold a stable value, move on open networks 24/7, and settle without a banking intermediary.
Adoption has gone vertical. Business-to-business stablecoin payment volume grew roughly 733% year over year heading into 2026, and total stablecoin transaction volume reached about $33 trillion in 2025. Juniper Research projects that cross-border B2B stablecoin payments will hit $5 trillion by 2035, up from an estimated $13.4 billion today, with the large majority of that future value coming specifically from cross-border business use. In short: the rail is being built right now, and businesses that learn it early gain a cost advantage.
How stablecoin cross-border payments actually work
The mechanics are simpler than the technology sounds. Every cross-border stablecoin payment follows the same three-stage path.
On-ramp, settlement, off-ramp
On-ramp. The sender converts local fiat (USD, EUR, etc.) into a stablecoin such as USDC or USDT, either from existing treasury or through a payment provider.
Settlement. The stablecoin moves across a blockchain network directly to the recipient's wallet. This is the step that replaces the entire correspondent-banking chain.
Off-ramp. The recipient either holds the stablecoin or converts it back to their local currency and withdraws to a bank account.
A provider like INXY handles the on-ramp, settlement, and off-ramp as a single flow, so the business never has to touch a crypto exchange directly.
Stablecoins and networks used
Most B2B volume runs on US-dollar stablecoins — USDC, USDT, and increasingly PYUSD — because they remove currency-volatility risk while keeping the speed of crypto. The network matters too, because it determines how fast and how cheaply a payment finalizes:
Solana — settlement finality in under half a second, with sub-cent fees.
Tron — finality in roughly one to two seconds; widely used for USDT.
Ethereum Layer-2s — low fees with fast confirmation, anchored to Ethereum security.
The practical takeaway: a payment that took three days on SWIFT can finalize in seconds on the right chain.
Stablecoins vs SWIFT: cost, speed, and transparency
The clearest way to understand the shift is a side-by-side comparison of low fee crypto payments against the legacy rails.
The economics are most dramatic at scale. Dropping from $40+ per wire to under $1 per transfer changes what is financially viable — micro-payments, frequent payouts, and thin-margin corridors that never made sense on SWIFT suddenly do.
Top use cases for global crypto transactions
Stablecoins are not a fit for every payment, but for global crypto transactions between businesses they solve real, recurring pain.
Supplier and vendor payments. Pay overseas manufacturers and service providers same-day instead of waiting for a wire to clear, improving supplier relationships and unlocking faster terms.
Contractor and team payouts. Pay international contractors and remote staff in stablecoins without losing 5–10% to fees and FX on every transfer. (INXY also covers dedicated crypto payroll.)
Marketplace and platform payouts. Distribute earnings to sellers, affiliates, or creators across many countries in a single batch, at predictable cost.
Treasury and intercompany transfers. Move funds between entities and regions instantly, holding value in a dollar-pegged asset rather than parking it in slow, fee-heavy banking channels.
These are exactly the corridors where the old system performs worst — many small-to-mid payments, many destinations, tight margins.
Are low fee crypto payments compliant? GENIUS Act and MiCA
A fair question from any finance or legal team: is this allowed? In 2026, the answer is increasingly yes — and the regulatory ground is firmer than it has ever been.
In the United States, the GENIUS Act established the first federal framework for payment stablecoins, requiring issuers to be licensed, to hold 1:1 reserves in high-quality liquid assets, and to honor redemption on demand. In the European Union, MiCA (Markets in Crypto-Assets) provides a parallel framework. Together they have moved stablecoins from a regulatory gray zone into supervised, standardized instruments — which is a large part of why institutional adoption accelerated.
What a regulated provider handles for you
Compliance does not have to live on your team. A regulated payment provider performs KYB (Know Your Business) onboarding, screens transactions against AML requirements, and maintains the audit trail you need for reporting. The business gets the speed and cost benefits of stablecoins while the provider absorbs the regulatory heavy lifting.
How to start accepting cross-border crypto payments
Getting started is closer to onboarding a payment processor than to learning crypto.
Choose a regulated provider that supports on-ramp, settlement, and off-ramp in your corridors — not a raw exchange.
Complete KYB onboarding and connect your bank account or treasury.
Pick your stablecoins and networks (USDC/USDT on a fast, low-fee chain) and set how recipients receive funds — held as stablecoin or auto-converted to local fiat.
Integrate and pay. Use the dashboard for one-off and batch payments, or the API to automate payouts inside your existing systems.
Once live, a cross-border payment that used to mean a wire form and a three-day wait becomes a few clicks and a few seconds.
The bottom line
Cross-border B2B payments are being rebuilt on stablecoin rails, and the trend lines — 733% volume growth, a projected $5 trillion market, and clear regulation under the GENIUS Act and MiCA — point in one direction. For businesses that move money internationally, stablecoins offer dramatically lower fees, near-instant settlement, and full transparency, without the volatility of traditional crypto. The companies adopting it now are the ones that will spend the next decade paying cents where their competitors pay tens of dollars.
Are stablecoin payments legal for business? Yes. In 2026, US-dollar stablecoins are regulated under the GENIUS Act in the United States and MiCA in the EU. Using a licensed provider keeps your KYB and AML obligations covered.
How fast is settlement? Depending on the network, a stablecoin payment finalizes anywhere from under a second (Solana) to a couple of minutes — versus one to three business days for a SWIFT wire.
What fees apply? The main cost is a small blockchain network fee, often under $1, plus any provider conversion fee on the on-ramp or off-ramp. This compares to $40–$80 per traditional international wire.
USDC or USDT for cross-border payments? Both are widely accepted dollar-pegged stablecoins. USDC is often preferred for its regulatory transparency; USDT has deeper liquidity in some corridors. A good provider supports both so you can match the recipient's preference.
How to Pay Contractors and Affiliates in USDC: A Practical 2026 Guide
Paying a global team through banks means FX spreads, 3–5 day waits, intermediary fees, and a recipient in another country who receives less than you sent. Paying them in USDC — a fully-reserved, dollar-pegged stablecoin — can turn that into a same-day transfer for cents. But doing it properly, at scale, and in a way your accountant accepts takes more than a wallet.
Paying a global team through banks means FX spreads, 3–5 day waits, intermediary fees, and a recipient in another country who receives less than you sent. Paying them in USDC — a fully-reserved, dollar-pegged stablecoin — can turn that into a same-day transfer for cents. But doing it properly, at scale, and in a way your accountant accepts takes more than a wallet.
This guide walks through how to pay contractors in USDC — the setup, the networks, the compliance basics, and how to keep your books in fiat.
Why businesses pay in USDC
USDC (issued by Circle) is a stablecoin pegged 1:1 to the US dollar and backed by cash and short-dated US Treasuries, with monthly attestations from Deloitte. For paying people, that combination is the point:
Stable value. Recipients get dollars, not a volatile asset. 1 USDC ≈ $1 at send and at cash-out.
Speed. Payments settle in minutes, 24/7, including weekends and holidays.
Global reach. Anyone with a wallet can receive, regardless of local banking.
Low cost. On low-fee networks, a payout costs cents rather than a wire fee.
Regulatory standing. USDC is MiCA-compliant in the EU, which makes it a durable choice for European corridors (more on that below).
Before you start: four things to get right
1. Confirm the recipient can receive USDC. They need a wallet address on a network you both support (Ethereum, Solana, Base, Polygon, and others). Confirm the network explicitly — a USDC transfer sent to the wrong network can be lost.
2. Decide who bears the fee. Will you gross up payments so the contractor receives the full agreed amount after network fees, or net it out? Set this in the contract.
3. Handle tax and classification. Paying in stablecoin doesn't change worker classification or your reporting obligations. Contractors are still responsible for their own taxes; you still keep records. Treat USDC payouts like any other payment for compliance purposes.
4. Keep fiat records. Your accounting should capture the fiat value at the time of payout, the fee, the recipient, and the transaction hash — not just on-chain data.
Method 1: Manual USDC payments
For a few contractors, you can pay directly from a self-custody wallet or exchange.
Steps:
Fund a wallet with USDC and the network's gas token.
Confirm each contractor's address and network in writing.
Send each payment; send a small test transfer first for new, large recipients.
Record each transaction hash against the invoice and its fiat value.
Limits: no automation, no built-in screening, and manual reconciliation. It works for a handful of people and breaks down beyond that.
Method 2: Bulk USDC payouts via CSV or API
For a real team — dozens or thousands of contractors, affiliates, or creators — a payout platform is the practical route. You prepare a recipient list and process it as one batch.
A typical flow:
Fund in fiat. With a fiat-native provider like INXY, top up in EUR or USD via SEPA or SWIFT — no need to buy crypto yourself.
Upload a CSV or call the API. Include recipient, amount, and network. The API path lets you trigger payouts straight from your own platform or billing system.
Automated compliance. The provider runs KYT and sanctions screening and validates addresses before sending.
Recipients get paid. USDC lands in minutes on supported networks.
Reconcile in fiat. Export batch-level records with fiat values, fees, payout IDs, and hashes.
This removes the two hardest parts of paying a global team in crypto: compliance and accounting. You never manage keys or gas, and your finance team works in EUR or USD.
Choosing the network for USDC payouts
USDC runs natively on several chains. For payouts:
Solana / Base / Polygon: cents per transfer, fast — ideal for high-volume contractor and affiliate payments.
Ethereum (ERC-20): the most liquid and widely integrated, but the most expensive — reserve it for recipients who require it.
Match the network to the recipient's wallet and the payout size; a platform can route this automatically.
Compliance: don't skip screening
Paying contractors across borders means you're exposed to sanctions and AML rules. Two non-negotiables:
Sanctions screening of recipient wallets before payout.
Transaction monitoring (KYT) to flag high-risk addresses.
Manual and script-based payouts leave this to you. A regulated payout provider builds it into the flow — which is often the difference between "using crypto rails" and "creating a banking-risk problem."
Frequently asked questions
Can I pay international contractors in USDC? Yes. Anyone with a compatible wallet can receive USDC in minutes, regardless of country, as long as it's legal in their jurisdiction. It's widely used for cross-border contractor, freelancer, and affiliate payments.
Do I need to hold crypto to pay contractors in USDC? No. A fiat-native platform lets you fund in EUR or USD and keep accounting in fiat while recipients receive USDC.
Is paying contractors in USDC legal? Paying in USDC is legal in most jurisdictions, but you remain responsible for worker classification, tax reporting, and AML/sanctions compliance — the same as any payment method. Check local rules for your recipients.
What does it cost to pay someone in USDC? On low-fee networks like Solana, Base, or Polygon, a USDC transfer costs cents. On Ethereum it can be several dollars. Choosing the network controls the cost.
How do I keep accounting clean when paying in USDC? Record the fiat value at payout time, the fee, and the transaction hash for each payment. Payout platforms generate these exports automatically.
Pay your global team without the crypto overhead
If you're paying contractors, affiliates, or creators at scale, you shouldn't be managing wallets, gas, and screening by hand. INXY's mass USDC payouts let you fund in fiat, pay globally in minutes, and reconcile in EUR or USD — with compliance built in. Building a broader payroll flow?

How to Send USDT to Multiple Wallets: A Step-by-Step Bulk Payout Guide
Manual works for a handful of payees; scripts work if you want to run infrastructure. If you'd rather send USDT to hundreds or thousands of recipients from a fiat balance — with screening and clean reporting built in — that's exactly what INXY's mass USDT payouts are built for.
Paying twenty affiliates, two hundred contractors, or two thousand players one transaction at a time does not scale. If you need to send USDT to multiple wallets, the method you choose determines your cost, your error rate, and how much of your finance team's week disappears into copy-pasting addresses.
This guide covers the three practical ways to run a bulk USDT transfer in 2026 — manual, scripted, and platform-based — with the trade-offs of each, the mistakes that cost real money, and how to keep clean records for accounting.
What "mass USDT payout" actually means
A mass USDT payout is a single, structured operation that distributes Tether to many recipients at once. Instead of initiating each transfer by hand, you prepare a list of addresses and amounts and process them as a batch.
Three things make this harder than it looks:
Network choice. USDT exists on Tron (TRC-20), Ethereum (ERC-20), BNB Chain (BEP-20), Solana, TON, Polygon and others. A recipient's address is network-specific — send TRC-20 USDT to an ERC-20 address and the funds are typically lost.
Fees at volume. A fee that looks trivial for one transfer becomes a line item when multiplied across thousands of recipients.
Reconciliation. Finance needs a fiat value, a timestamp, and a transaction hash for every payout — not just a wall of blockchain data.
Keep these three in mind; every method below is really a different answer to them.
Method 1: Manual transfers from a wallet or exchange
The simplest approach is to send USDT one recipient at a time from a self-custody wallet (MetaMask, Trust Wallet, Tronlink) or an exchange account.
When it works: fewer than ~10 recipients, infrequent payouts, no automation budget.
Steps:
Confirm each recipient's network and address in writing. Never assume the network.
Fund your wallet with enough USDT and the native gas token (TRX for TRC-20, ETH for ERC-20, and so on).
Send each transfer, double-checking the first and last four characters of every address.
Save each transaction hash against the recipient's name for your records.
The catch: manual sending does not scale and has no safety net. A single mistyped address is irreversible. There is no batch confirmation, no built-in fiat reporting, and no sanctions screening. Beyond a handful of recipients, error risk climbs fast.
Method 2: Scripts and smart-contract batching
Technical teams can automate payouts with the blockchain's own tooling — a script that loops through a recipient list, or a "multisend" / "disperse" smart contract that pushes many transfers in one on-chain transaction.
When it works: you have engineering resources, a stable set of networks, and you want control over the flow.
What you gain:
Batching efficiency. Multisend contracts bundle many recipients into a single transaction, which can reduce total gas versus sending individually on some networks.
Full automation. A script can pull addresses from your database and fire payouts on a schedule.
What you take on:
Key management. Your script needs access to a funded hot wallet holding private keys — an operational and security liability.
Gas handling. You must monitor and top up the native token on every network you use.
No compliance layer. Scripts don't screen recipients against sanctions lists or flag high-risk addresses. That's on you.
Accounting glue. You still have to convert on-chain data into fiat-denominated records your auditors will accept.
Scripting trades human error for engineering overhead. It's powerful, but you are now running payment infrastructure as a side project.
Method 3: A payout platform (CSV or API)
A dedicated payout platform abstracts the wallet, keys, gas, and networks away. You upload a CSV of recipients or call an API, and the platform handles conversion, routing, screening, and delivery.
When it works: recurring payouts, dozens to thousands of recipients, finance teams that need clean fiat reporting, and businesses that don't want to become a crypto operation.
How a typical batch runs:
Fund in fiat or stablecoin. Top up a balance — with a provider like INXY you can fund in EUR or USD via SEPA or SWIFT, so you never have to source crypto yourself.
Upload or connect. Submit a CSV (recipient, amount, network) or send the batch through the API.
Automated checks. The platform runs KYT and sanctions screening, auto-converts, and routes each payout to the right network.
Recipients get paid. Delivery happens in minutes on supported low-fee networks.
Report in fiat. You get batch-level exports with fiat values, fees, payout IDs, and transaction hashes — ready for reconciliation.
The trade-off is that you rely on a provider, but you remove key management, gas operations, compliance gaps, and accounting cleanup in one move.
Five mistakes that cost real money
Wrong network. The most common irreversible loss. Always match the recipient's network to the address.
Forgetting gas. A wallet full of USDT can't move without the native token for fees.
No test transfer. For a new large recipient, send a small amount first and confirm receipt.
Skipping screening. Paying a sanctioned or high-risk address is a legal and banking risk, not just a crypto one.
Weak records. If you can't tie every hash to a fiat value and a recipient, month-end close becomes painful.
Frequently asked questions
Can I send USDT to many wallets in one transaction? On some networks, yes — a "multisend" smart contract bundles multiple recipients into one on-chain transaction. Otherwise, batching is handled off-chain by a platform that submits the transfers for you.
What's the cheapest way to send USDT in bulk? Low-fee networks such as Tron (TRC-20), Solana, and TON dramatically reduce per-transfer cost versus Ethereum. See our full USDT network fees comparison.
Do I need to hold crypto to run USDT payouts? Not with a fiat-native platform. You can fund in EUR or USD, keep your accounting in fiat, and let the provider handle conversion and delivery.
Is bulk USDT sending safe? The transfer itself is irreversible, so accuracy matters. Reputable platforms add address validation, KYT, and sanctions screening to reduce risk — protections that manual and script-based methods lack.
Scale it without the overhead
Manual works for a handful of payees; scripts work if you want to run infrastructure. If you'd rather send USDT to hundreds or thousands of recipients from a fiat balance — with screening and clean reporting built in — that's exactly what INXY's mass USDT payouts are built for.
