Running an affiliate network means managing dozens — or hundreds — of payment relationships simultaneously. When those partners operate across different countries and expect crypto compensation, the bottleneck isn't traffic or conversions: it's payout infrastructure. Manual crypto transfers don't scale. Exchange withdrawal APIs are built for single recipients. And treasury teams shouldn't be copying wallet addresses one by one every payout cycle.

INXY's Mass Payouts API solves this at the infrastructure level — letting affiliate programs send BTC, USDT, ETH, and other crypto assets to hundreds of recipients in a single payout cycle — with AML/KYT compliance handled automatically on every transaction.

Why Affiliate Networks Are Moving to Crypto Payouts

Cross-Border Friction with Traditional Rails

Bank wires and PayPal are the default — but they're slow, regionally inconsistent, and expensive for international affiliate programs. SWIFT transfers take 2–5 business days and carry correspondent bank fees. PayPal blocks accounts in dozens of jurisdictions. For an affiliate network paying partners in Southeast Asia, Eastern Europe, or Latin America, these aren't edge cases — they're the norm.

Crypto payouts bypass this entirely. On-chain settlement means funds arrive in minutes regardless of recipient geography, with no correspondent banking dependencies.

Affiliates Demanding Crypto Compensation

Across iGaming, Forex, and SaaS verticals, crypto-denominated affiliate commissions have shifted from a niche perk to a standard expectation. High-volume affiliates — those generating meaningful revenue for programs — increasingly prefer USDT or BTC over fiat because it sidesteps local banking restrictions, enables faster compounding, and reduces currency risk on earnings held in volatile local currencies.

Speed and Cost Advantages of On-Chain Settlement

For affiliate programs running weekly or bi-weekly payout cycles, speed matters. Crypto settlements are typically confirmed within minutes to hours — compared to the 2–5 day window of international bank transfers. On-chain fees, while variable, are often lower than the cumulative cost of wire fees multiplied across a partner base of 100+ recipients.

How INXY's Mass Payout API Works for Affiliate Programs

The INXY affiliate payout workflow is designed to run without manual intervention once integrated:

1. Register your company and pass KYB verification — powered by Sumsub, typically completed within 1–2 business days.

2. Fund your INXY account — deposit BTC, USDT, ETH, or hold EUR/USD and use the buy_crypto flag to auto-convert at payout time.

3. Build your payout batch — compile affiliate wallet addresses, amounts, and optional memo fields. There is no hard cap on the total number of recipients per payout cycle.

4. Submit via the INXY Mass Payouts API — a single REST call with a JSON payload covering your entire affiliate payment run.

5. INXY runs AML/KYT screening automatically on every outgoing transaction — no manual review required from your team.

6. Funds are broadcast on-chain and confirmed — affiliates receive their payouts directly to their wallets.

Webhook callbacks notify your system of each transaction status in real time. No per-transaction dashboards. No manual approvals. No treasury team bottleneck.

Supported Cryptocurrencies for Affiliate Payouts

Bitcoin (BTC)

Bitcoin remains the preferred settlement currency for affiliates in iGaming and high-risk verticals. INXY sends BTC payouts on the Bitcoin mainnet — no Lightning Network at this stage. Settlement time depends on network congestion and the fee tier selected at submission. Affiliates receive BTC directly to any standard Bitcoin wallet address.

USDT (TRC-20 / ERC-20)

USDT is the dominant stablecoin for affiliate compensation — it eliminates volatility risk while preserving the speed and borderless nature of crypto settlement. INXY supports USDT on both TRC-20 (Tron network, low fees) and ERC-20 (Ethereum network). For programs where affiliates prefer stable value, USDT payouts via INXY are the most practical option.

ETH and Other Supported Assets

Ethereum (ETH) and additional crypto assets are supported through INXY's payment infrastructure. Programs can diversify payout currencies based on affiliate preference or treasury composition. INXY's buy_crypto flag means programs can hold EUR or USD in their INXY balance and auto-convert to whichever asset the affiliate batch requires at payout time.

INXY vs Manual Crypto Payouts vs Exchange APIs

Not all crypto payout methods are equivalent. Here's how INXY's Mass Payouts infrastructure compares to alternatives affiliate programs typically try first:

For affiliate programs paying more than 10 partners per cycle, the operational gap between INXY and manual methods compounds rapidly. A single API call replacing 200 individual wallet transactions isn't a marginal improvement — it's a different category of infrastructure.

Compliance and AML Screening — Built for Regulated Affiliate Programs

Affiliate networks operating in regulated verticals — iGaming, Forex, fintech — face increasing scrutiny on outgoing payment flows. INXY's compliance stack handles this automatically, without requiring programs to build their own AML logic.

KYT Screening on Every Outgoing Transaction

Every crypto payout processed through INXY is screened using KYT (Know Your Transaction) analysis. KYT evaluates the risk profile of recipient wallet addresses — flagging addresses associated with sanctions lists, mixers, or high-risk counterparties — before funds are broadcast on-chain.

Transaction Statuses: Cleared / Pending Review / On Hold

Each transaction is assigned a compliance status automatically: Cleared (processed immediately), Pending Review (flagged for manual review before settlement), On Hold (suspended pending investigation), or in rare cases Seized. Programs receive status updates via webhook, allowing downstream systems to handle edge cases programmatically.

Compliance Documentation for Your Records

INXY generates compliance documentation for all processed transactions. For affiliate programs that need to demonstrate AML controls to regulators, payment processors, or banking partners, this documentation provides an audit trail without requiring programs to build their own reporting infrastructure.

Who Uses INXY for Affiliate Crypto Payouts?

iGaming and Betting Affiliate Networks

iGaming is the highest-volume use case for crypto affiliate payouts. Programs managing hundreds of partners across multiple jurisdictions use INXY to run weekly BTC and USDT payment cycles. We handle payout cycles of any size — from dozens to hundreds of partners — without manual intervention; larger programs run sequential batches. KYT compliance is particularly valuable here, given the regulatory environment iGaming programs operate in.

Forex and Fintech Referral Programs

Forex brokers and fintech companies running IBs (Introducing Brokers) or referral programs use INXY to settle USDT and ETH commissions with partners globally. These programs often have partners in jurisdictions where receiving USD via wire is slow or restricted — crypto settlement sidesteps that friction entirely.

SaaS Partner and Reseller Programs

SaaS companies with global reseller networks use INXY to pay partner commissions in crypto as an alternative to Stripe payouts or wire transfers. The buy_crypto flag is particularly practical here: finance teams hold EUR or USD in the INXY balance, and INXY handles conversion and disbursement at the scheduled payout date — no active crypto treasury management required.

Frequently Asked Questions

How many affiliates can I pay in one batch?

INXY's Mass Payouts API is designed to handle payout cycles of any scale. There is no hard limit on the total number of recipients per cycle — whether you're paying dozens or hundreds of partners, the infrastructure scales to match your program's volume.

Do I need to hold crypto to pay affiliates?

No. If your INXY account holds EUR or USD, you can use the buy_crypto flag on any payout request. INXY will automatically purchase the required crypto at current market rates and disburse it to the recipient batch — without requiring you to manage a live crypto treasury.

Is KYB required to use INXY?

Yes. INXY is a B2B platform and requires KYB (Know Your Business) verification for all accounts. The KYB process is powered by Sumsub and typically completes within 1–2 business days. Individual accounts are not supported.

If you’ve spent any time navigating the fintech landscape in 2026, you’ve likely noticed that "crypto payment gateway" and "crypto payment processor" are thrown around like synonyms. In casual conversation, that’s fine. But if you’re a business owner in the EU trying to optimize your checkout or manage a complex treasury, the distinction matters. It’s the difference between a sleek front-end interface and the heavy-duty engine room that actually moves the money.

Let’s break down the technicalities of these two components and see how they work together to modernize your business.

The Crypto Payment Gateway: Your Digital Storefront

Think of the Crypto Payment Gateway as the "front-end" layer. It is the bridge between your website and the blockchain. Its primary job is to handle the customer-facing part of the transaction.

When a customer clicks "Pay with Crypto," the gateway jumps into action:

• Checkout UI: It displays the QR code or wallet address.
• Real-time Rate Locking: It calculates the exact exchange rate between, say, Bitcoin and the Euro, and freezes it for a few minutes so the customer knows exactly what they’re paying.
• Data Transmission: It securely passes the transaction details to the processor.

Essentially, the gateway is the digital equivalent of a Point-of-Sale (POS) terminal. It’s all about user experience and making sure the "handshake" between the customer and the merchant is secure and seamless.

The Crypto Payment Processor: The Engine Room

While the gateway handles the "hello," the Crypto Payment Processor handles the "settlement." This is the back-end infrastructure that manages the lifecycle of the funds after the customer hits send.

The processor’s responsibilities are significantly broader:

• Blockchain Validation: It monitors the network to confirm the transaction has reached the required number of blocks.
• Settlement & Conversion: This is the big one. If you invoiced for €1,000 but the customer paid in Bitcoin, the processor handles the conversion and ensures those funds are ready for your bank account.
• Compliance (KYC/AML): It runs the necessary checks to ensure the transaction isn't linked to illicit activity—a non-negotiable for EU-based businesses under current regulations.
• Payouts: It manages the transfer of funds from the crypto ecosystem into your corporate SEPA or SWIFT account.

Why the Distinction Matters for EU Businesses

In the European fintech market, precision is everything. If you only use a "gateway" without a robust processing layer, you might find yourself with a wallet full of crypto but no easy way to pay your local taxes or suppliers in fiat.

Conversely, a processor without a good gateway might provide great liquidity, but your customers will struggle with a clunky, manual checkout process that kills your conversion rate.

This is where integrated solutions come in. Platforms like INXY bridge this gap by functioning as a unified ecosystem. By combining an EU-licensed gateway (the part your customers see) with a powerful processing engine (the part your accountant loves), it removes the friction of managing two separate services.

Why "All-in-One" is the 2026 Standard

Modern fintech has moved past fragmented tools. For instance, INXY Payments focuses heavily on high-conversion gateways specifically for e-commerce, infrastructure and hosting providers. Because they operate as an EU-authorized VASP (Virtual Asset Service Provider), the processing side is built-in.

For a merchant, this means:

1. Zero Volatility: The rate is locked at the gateway level and settled instantly at the processor level.
2. Mass Payouts: You can collect payments via the gateway and immediately use those funds to pay global affiliates or remote teams via the processor’s API.
3. Legal Clarity: Since the processor handles the KYB (Know Your Business) and AML checks, the funds landing in your bank account are "clean" and fully documented for tax purposes.

‍

Summary

A gateway gets you paid; a processor keeps you in business. While they serve different technical functions, the most successful companies in 2026 are those that don’t make their customers (or their dev teams) choose between the two.

By using an integrated platform like INXY, you get the best of both worlds: a checkout experience that converts and a back-end that settles without the headaches of traditional banking delays.

“Web3 payments” describe a new way to move money in which value travels directly across a blockchain network instead of through banks and card schemes. Unlike traditional online transactions, blockchain payments settle peer-to-peer on a public ledger, are verifiable by anyone, and can run without a central intermediary holding the funds. For businesses, this means faster settlement, lower cross-border costs, and programmable money that can enforce its own rules.

This guide explains what web3 payments are, how they work under the hood, where smart contracts fit in, and how they compare to the crypto checkout flows most merchants already know. It is written for founders, finance teams, and product managers evaluating whether on-chain rails belong in their stack.

What Are Web3 Payments?

Web3 payments are transactions executed on decentralized blockchain networks, where ownership of funds is tied to a cryptographic wallet rather than a bank account. The term “web3” refers to the third era of the internet — one built on open, user-owned protocols. In a payment context, web3 crypto payments let a payer send value (typically stablecoins such as USDC or USDT, or assets like ETH and BTC) straight to a recipient’s wallet, with the network itself confirming and recording the transfer.

Three properties separate web3 payments from conventional digital payments:

• Self-custody. The payer controls the funds via private keys until the moment of transfer — there is no card issuer or bank acting as gatekeeper.
• On-chain settlement. The transaction is final once confirmed by the network, usually in seconds to minutes, with no multi-day clearing cycle.
• Programmability. Logic can be attached to the payment itself, so funds release only when predefined conditions are met.

The market context matters. According to recent industry analysis, fiat-backed stablecoins surpassed $300 billion in market capitalization in late 2025, with annualized on-chain settlement volumes in the mid-$20-trillion range — evidence that web3 rails are moving from experiment to real economic activity.

It helps to see where web3 payments sit relative to terms you already use. “Crypto payments” is the umbrella term for paying with digital assets at all. “Web3 payments” is the subset that runs on open, permissionless networks with user-held funds — as opposed to a closed processor that simply accepts coins and settles them to your bank. That difference in architecture is what unlocks the speed, reach, and automation covered below.

How Web3 Payments Work: Blockchain & Wallets

Blockchain payments rely on three components working together: a wallet that holds the keys, a blockchain network that validates transactions, and (for business use) a gateway that translates the on-chain event into something an accounting system can read. Here is the flow in plain terms.

The role of self-custody wallets

A crypto wallet does not “store” coins; it stores the private keys that prove ownership of a balance recorded on-chain. When a customer pays, their wallet signs the transaction with that key, authorizing the network to move the balance to the merchant’s address. Because the key never leaves the user, there is no card number to steal and no chargeback to reverse — a structural difference from card payments.

On-chain settlement vs. traditional rails

In a card transaction, authorization, clearing, and settlement happen across several institutions over one to three business days. With blockchain payments, validators confirm the transfer and write it to an immutable ledger in a single step. The table below summarizes the practical differences.

Smart Contract Payments Explained

Smart contract payments are blockchain transactions governed by self-executing code. A smart contract is a program deployed on-chain that automatically performs an action — release funds, split a payment, issue a refund — when its conditions are satisfied. No human has to intervene, and no party can alter the outcome once the contract is live.

Automated & programmable payments

This is where web3 moves beyond simple transfers. A smart contract can hold funds in escrow and release them only when a delivery is confirmed, automatically distribute revenue among several wallets, or stream a salary continuously over time. For businesses, programmable money reduces manual reconciliation and removes the trust gap in multi-party deals.

Consider a marketplace that owes three parties on every sale: the seller, an affiliate, and the platform itself. With cards, that single payment is captured, then split later through separate payout runs and reconciliation. A smart contract executes the split atomically — the moment funds arrive, each wallet receives its share in the same transaction. The same logic powers milestone-based contractor payments, automated refunds, and subscription renewals, all without a card on file or a manual approval step.

• Escrow: funds lock until both sides meet their obligations.
• Revenue splits: a single incoming payment is divided across partners in one transaction.
• Recurring & usage-based billing: subscriptions and metered charges execute on-chain without a card on file.

Tokenized payment solutions

Tokenized payment solutions represent real-world value — a dollar, an invoice, a loyalty credit — as a transferable token on a blockchain. Stablecoins are the most widely used example: a token pegged 1:1 to fiat that combines the stability of a currency with the speed of crypto. Industry research estimates that B2B flows already account for roughly 40% of real-economy stablecoin payments and are growing about 65% per year, which is why tokenized settlement is becoming the default rail for cross-border business payments.

Web3 Payments vs. Traditional Crypto Checkout

Many merchants already “accept crypto” through a hosted checkout that converts coins to fiat. That is a useful on-ramp, but it is not the same as a full web3 payment model. The distinction is about who controls the funds and whether the payment carries logic.

‍

In practice the two coexist. A business might use a custodial checkout for retail customers while using native, programmable rails for supplier payouts and partner settlements. For a deeper breakdown of provider roles, see our guide on the difference between a crypto payment gateway and a processor.

Benefits & Risks for Businesses

Web3 payments — and the broader category of blockchain smart contracts for business — offer clear operational upside, but they come with trade-offs that finance and compliance teams should weigh.

Key benefits:

• Near-instant, 24/7 settlement that frees up working capital.
• Lower cross-border fees by removing correspondent-banking layers.
• No chargebacks, reducing fraud exposure for digital goods.
• Automation of escrow, splits, and recurring billing through smart contracts.

Risks to manage:

• Price volatility on non-stablecoin assets — most businesses settle in stablecoins to neutralize this.
• Irreversibility means errors and misdirected payments are hard to recover.
• Regulatory obligations: under frameworks like the EU’s MiCA, you must work with a licensed VASP/CASP and apply KYC/AML and Travel Rule checks.
• Smart-contract risk: poorly audited code can be exploited, so use vetted, audited contracts.

For most companies the practical answer is not to choose between safety and innovation, but to adopt web3 payments through a partner that has already solved custody, compliance, and key management. That keeps the operational benefits — speed, automation, global reach — while shifting the hardest security and regulatory work to infrastructure built for it.

How to Start Accepting Web3 Payments

You do not need to build blockchain infrastructure in-house. A compliant gateway abstracts the wallet, network, and conversion layers so you can accept on-chain payments with a standard integration. A practical path:

1. Choose your settlement asset. Stablecoins (USDC, USDT, DAI) are the standard for business to avoid volatility.
2. Select a regulated provider. Confirm licensing, multi-chain support, and KYC/AML coverage for your regions.
3. Integrate via API or plugin. Add the checkout or payout flow and connect webhooks to your back office.
4. Decide what to automate. Map which payments — escrow, splits, recurring — benefit from smart-contract logic.

INXY provides a regulated, EU-compliant gateway for exactly this. Explore the web3 payments solution and our smart-contract payment infrastructure, or read how to accept crypto payments in 2026 for the full setup walkthrough.

FAQ

What are web3 payments in simple terms? They are payments sent directly between crypto wallets over a blockchain, without a bank or card network in the middle. The network verifies and records the transfer.

Are web3 payments safe? The underlying blockchain settlement is highly secure and tamper-resistant. The main risks are user error, asset volatility, and smart-contract bugs — all manageable by using stablecoins, audited contracts, and a regulated gateway.

What is a smart contract payment? A payment controlled by on-chain code that executes automatically when set conditions are met — for example, releasing escrowed funds once delivery is confirmed.

How are web3 payments different from accepting Bitcoin at checkout? A standard crypto checkout is custodial and converts coins to fiat. Native web3 payments keep funds in self-custody and can carry programmable logic, making them better suited to recurring, B2B, and multi-party flows.
