Find answers to common questions about using CryptoMMO for USDT payments across multiple blockchain networks.
General Questions
What is CryptoMMO?
CryptoMMO is a payment gateway that enables businesses to accept USDT payments across multiple blockchain networks including Ethereum, Binance Smart Chain, and Arbitrum, with more networks coming soon.
How does CryptoMMO work?
CryptoMMO provides API endpoints and developer tools that allow businesses to integrate USDT payments into their websites or applications. When a customer makes a payment, our system verifies the transaction on the blockchain and notifies your application once the payment is confirmed.
Which cryptocurrencies do you support?
Currently, we support USDT (Tether) on Ethereum, Binance Smart Chain, and Arbitrum networks. We are working to add support for USDT on Polygon, Avalanche, and Optimism networks in the near future.
Is CryptoMMO available worldwide?
Yes, CryptoMMO is available for businesses and users worldwide. As blockchain technology is borderless, you can accept payments from customers anywhere in the world without restrictions.
Technical Questions
How long do transactions take to confirm?
Transaction confirmation times vary by network. Typically, Ethereum transactions take about 5-20 minutes, Binance Smart Chain transactions take 15-45 seconds, and Arbitrum transactions take around 1-5 minutes. These times may vary depending on network congestion.
What happens if a transaction fails?
If a transaction fails on the blockchain, it will not be processed and no funds will be transferred. Our system monitors transaction status and notifies your application about failures. Your customer will need to retry the payment.
How do I handle network selection for my customers?
You can either let customers choose their preferred network or implement logic to recommend networks based on factors like transaction fees, speed, or user location. Our API provides information about current network conditions to help with this decision.
Can I generate unique payment addresses for each transaction?
Yes, our API allows you to generate unique deposit addresses for each customer transaction, enhancing privacy and making it easier to track individual payments.
Integration Questions
How do I integrate CryptoMMO with my website?
You can integrate using our JavaScript SDK, RESTful API, or server-side libraries. We provide detailed integration guides and code examples in our developer documentation.
Do you offer plugins for common platforms?
Yes, we offer plugins for popular e-commerce platforms such as WooCommerce, Shopify, and Magento. These plugins simplify the integration process and provide ready-to-use payment options for your customers.
Is there a testing environment available?
Yes, we provide a sandbox environment where you can test the integration without using real funds. This allows you to fully test your payment flow before going live.
What kind of technical support do you offer during integration?
We offer comprehensive technical support during integration, including direct communication with our developer team, detailed documentation, and integration examples. Enterprise customers also receive priority support and dedicated integration assistance.
Security Questions
How secure is CryptoMMO?
Security is our top priority. We employ industry-standard security practices, including end-to-end encryption, two-factor authentication, cold storage for funds, and regular security audits by third-party experts.
Do you hold customer funds?
No, we operate as a non-custodial payment processor. Payments are made directly from your customer's wallet to your wallet address, without us holding the funds at any point.
How do I verify that a payment has been completed?
Our system verifies transactions on the blockchain and sends webhook notifications to your server once payments are confirmed. You can also verify transactions manually using blockchain explorers for each network.
What happens if there's a blockchain fork or network issue?
In the event of a blockchain fork or major network issue, we will pause processing on the affected network until stability is restored. We maintain communication with our users throughout any such events and provide guidance on how to proceed.
Pricing & Billing
What are CryptoMMO's fees?
We charge a small percentage fee per transaction, typically 0.5-1% depending on your volume. There are no setup fees or monthly charges for standard accounts. Enterprise customers can negotiate custom pricing based on volume.
Do I need to pay network transaction fees?
Yes, blockchain network fees (gas fees) apply to all transactions. These fees vary by network and congestion levels. You can choose whether your business covers these fees or if they're passed on to customers.
How and when do I pay the service fees?
Service fees are automatically deducted from each transaction. For enterprise customers, we offer monthly billing options.
Are there any volume discounts available?
Yes, we offer tiered pricing with reduced fees for higher transaction volumes. Please contact our sales team to discuss your specific needs and potential custom pricing.
