In short
Developers & Builders
Most crypto payment integrations force you to write smart contracts, manage multiple chain clients, or trust a third party with custody. Dynopay gives developers a single REST API that covers Bitcoin, Ethereum, Solana, Tron, Polygon, and XRP Ledger—15+ assets total—while every payment settles non-custodially to the wallet you control. No monthly fees, no setup costs, and your first transaction is completely free.
Why Dynopay
Everything you need to get paid in crypto
Non-custodial by design. You keep the wallet, we handle the checkout.
One API, 15+ Cryptocurrencies
Accept Bitcoin, ETH, USDT (three networks), USDC, SOL, XRP, RLUSD, and more through a single REST interface. No need to run nodes or write chain-specific logic.
Non-Custodial by Design
Payments flow directly to the wallet address you provide during setup. Dynopay never holds, freezes, or controls your funds—you retain custody from checkout to settlement.
Webhooks and Real-Time Events
Listen for payment confirmations, refunds, and status changes via HTTP callbacks. Build dynamic order fulfillment, subscription logic, or conditional workflows without polling.

FAQ
Frequently asked questions
Everything people ask before signing up.
What cryptocurrencies does the Dynopay API support?
Dynopay supports Bitcoin, Litecoin, Bitcoin Cash, Dogecoin, Ethereum (including USDT, USDC, and RLUSD on ERC-20), Polygon (MATIC and USDT), Tron (TRX and USDT-TRC20), Solana, and XRP Ledger (XRP and RLUSD)—15+ assets in total behind one REST API.
How much does Dynopay charge per transaction?
Dynopay charges a volume-tiered platform fee that starts at 1.5 percent plus one dollar per successful payment and drops automatically to 0.5 percent at scale based on settled volume. Your first payment is completely free, and there are no monthly or setup fees.
Do I need to deploy smart contracts to accept payments?
No. Dynopay handles chain interaction, address generation, and confirmation monitoring for you. You call a REST endpoint, receive a payment address, and listen for webhook events—no Solidity, no audits, no gas management.
Is Dynopay custodial or do I control the funds?
Dynopay is entirely non-custodial. Every payment settles directly to the wallet address you specify during onboarding. Dynopay never holds, moves, or controls your cryptocurrency at any point in the transaction lifecycle.
Can I test the API before going live?
Yes. Dynopay provides a sandbox environment with test API keys so you can simulate payments, trigger webhooks, and validate your integration logic before processing real transactions on mainnet.
