Crypto payments are no longer a niche experiment. They have become a standard option alongside credit cards and bank transfers. Businesses that want to tap into this growing market face a common problem: processing cryptocurrency directly requires managing multiple blockchain networks, token standards, wallet security, and price volatility. Loop Crypto was built to solve exactly that. This guide covers everything you need to know about the platform, its capabilities, integrations, and how it compares to alternatives in the space.
What Is Loop Crypto?
Loop Crypto is a crypto and stablecoin payment processor. It provides a suite of APIs and tools that allow merchants, billing platforms, and payment providers to accept cryptocurrency payments without dealing with the underlying blockchain complexities. Instead of building custom infrastructure for each network and token, businesses can plug into Loop’s standardized API layer and treat crypto payments similarly to traditional payment rails.
The platform supports one-time purchases, subscription billing, invoicing, and recurring payments. Merchants can settle funds in either cryptocurrency or fiat currency, giving them flexibility depending on their risk tolerance and operational needs. Loop denominates pricing in US dollars at the time of purchase, using oracle-based pricing to calculate the exact crypto amount owed, which eliminates manual conversion work for merchants.
Choosing a reliable crypto payment gateway is critical when evaluating any solution for accepting digital currencies. Loop positions itself as a full-stack processor rather than a simple routing tool, offering settlement options, customer portals, and analytics alongside raw payment processing.
Supported Networks and Tokens
Loop operates across multiple blockchain networks, allowing merchants to accept payments from customers regardless of which chain they prefer. The supported networks include Ethereum, Polygon, Base, Optimism, Arbitrum, and Solana. Any EVM-compatible network can also be added upon request.
On these networks, Loop accepts stablecoins like USDC and USDT, major cryptocurrencies like ETH and SOL, and any ERC-20 or SPL token. Merchants configure which tokens they want to accept per network during setup.
| Network | Token Examples | Settlement Options |
|---|---|---|
| Ethereum | ETH, USDC, USDT | Fiat or Crypto |
| Solana | SOL, USDC, USDT | Fiat or Crypto |
| Polygon | MATIC, USDC | Fiat or Crypto |
| Base | ETH, USDC | Fiat or Crypto |
| Optimism | ETH, USDC | Fiat or Crypto |
| Arbitrum | ETH, USDC | Fiat or Crypto |
This multi-network approach means a single merchant can accept payments from a broad range of wallets and user preferences without maintaining separate integrations for each chain.
Core Features
Payment Links
Loop generates hosted payment pages that customers can visit to complete purchases, start subscriptions, or pay invoices. These links can be shared directly via email, embedded on websites, or distributed through partner platforms. Each payment link carries metadata — such as invoice numbers, client names, and item descriptions — that helps merchants track and reconcile on-chain transactions against off-chain records.
Subscription Payments
Recurring billing is one of Loop’s standout capabilities. The platform supports native autopay on Solana, meaning subscriptions can renew automatically without requiring customers to manually authorize each payment. For EVM networks, Loop manages recurring payment logic through its API, handling retry mechanisms, grace periods, and churn reduction workflows. This makes it suitable for SaaS companies, content creators, and service providers who bill regularly.
Customer Portal
Merchants and their customers can use Loop’s customer portal to manage allowances, update payment methods, and review transaction history. This reduces support overhead by giving users self-service access to their payment settings instead of relying on manual intervention.
Data Analytics
Loop provides real-time analytics that combine data from both crypto and fiat payments in a single dashboard. Merchants can track revenue trends, payment method preferences, conversion rates, and settlement statuses without switching between multiple systems.
Settlement Options
One of Loop’s key differentiators is its flexible settlement model. Merchants can choose to receive payments in cryptocurrency, keeping funds on-chain for reinvestment or long-term holding, or opt for fiat settlement where Loop automatically converts received crypto into traditional currency and deposits it into a linked bank account.
For fiat settlement, merchants complete KYC/KYB verification and provide banking details. Once approved, Loop handles the entire off-ramping process automatically. The platform creates dedicated wallets for receiving crypto on each supported network and manages the conversion workflow behind the scenes.
| Settlement Type | Requirements | Process |
|---|---|---|
| Crypto | Wallet address per network | Funds sent directly to merchant wallet |
| Fiat | KYC/KYB approval + bank account | Auto-converted and deposited to bank |
Fiat settlement is not available for all network-token combinations, so merchants should verify supported pairs before configuring their accounts.
Integrations
Loop offers several integration paths depending on a business’s existing infrastructure.
Stripe Integration — Merchants already using Stripe can add Loop alongside their existing setup. Loop processes all crypto payments and syncs transaction data back to Stripe, allowing merchants to manage both fiat and crypto operations from a single dashboard.
OpenPay (now Airwallex) — Loop partners with OpenPay to enable dual-currency billing, combining crypto and fiat payments within one platform.
Xero — An accounting integration that pushes crypto payment data directly into Xero for bookkeeping and financial reporting.
Custom API — Developers can build custom integrations using Loop’s full API suite, which includes endpoints for creating invoices, monitoring payment status, managing subscriptions, and configuring payout destinations.
How Loop Handles Volatility
Price volatility is one of the biggest concerns for merchants accepting cryptocurrency. Loop addresses this through dollar-denominated pricing. When a customer initiates a payment, Loop queries a pricing oracle to determine the exact amount of the chosen cryptocurrency needed to match the product’s stated price in US dollars. This ensures the merchant receives the expected value regardless of market fluctuations.
Merchants who want zero exposure to volatility can simply accept only stablecoins. Those comfortable with crypto holdings can accept volatile assets knowing the USD anchor protects their revenue at the point of sale.
Who Should Use Loop?
Loop serves two primary audiences. First, direct merchants who want to add crypto payments to their existing checkout flow without hiring blockchain developers. Second, payment providers and billing platforms that want to offer crypto as a payment option to their own customer base. Loop’s API-first design makes it particularly well-suited for the latter group, as payment processors can white-label the functionality and present it as part of their own product offering.
Getting Started
Setting up with Loop involves creating a merchant entity, selecting supported networks and tokens, configuring a payout destination, and generating your first payment link or integrating the API into your existing system. The platform provides documentation, SDKs, and developer resources to streamline the process. For those using Stripe or other integrated partners, setup can be completed in minutes rather than weeks.
