About this Gig
Disconnected checkout, wallet, confirmation and swap features make crypto payments costly to support. I will integrate a crypto payment gateway and wallet API into your product or develop a focused payment system.
Your package can include:
1. Crypto checkout or payment links
2. Wallet addresses and balance views
3. Deposit and withdrawal workflows
4. Stablecoin and token payment status
5. Token swap provider integration
6. Webhooks, invoices and admin records
My service fits SaaS platforms, marketplaces, digital products and businesses that need traceable crypto payments without forcing staff to monitor transactions manually. The scope can cover one gateway integration, a wallet and swap flow or a larger merchant payment portal.
Blockchain payments are irreversible. Refund operations, custody, network fees, liquidity and compliance must be defined in your business rules and supported by the provider.
Before ordering, send your application stack, payment journey, target assets, networks, wallet model and preferred gateway. I will confirm provider compatibility and the correct package.
Keep your assets and information safe
Cryptocurrency services focus solely on developing and programming. Never share sensitive information or private keys with others.

FAQ
01. Can you add crypto payments to my existing website or app?
Yes. Share the framework, current checkout and provider documentation. The Basic package is intended for one focused integration into an existing product.
02. Can customers pay with several tokens?
Yes, if your chosen gateway supports them. The Premium package can cover multi-token checkout, while the exact networks and assets must be agreed.
03. Can the system swap received tokens?
A supported swap provider can be integrated. Swap quotes, slippage, liquidity, network fees and regional availability remain provider-dependent.
04. Do crypto payments support chargebacks?
Onchain transfers are usually irreversible. Any refund or dispute process must be designed separately and cannot be treated like a card chargeback.
