Product Scope
Hosted Ramp & Onchain Payment APIs is the Binance Pay Onchain product path for partners integrating Binance-powered hosted ramp and onchain payment flows.
This product path supports three main use cases:
1. On-ramp APIs
On-ramp APIs allow partners to offer a hosted fiat-to-crypto purchase flow. A user can start from the partner experience, continue through a Binance-powered checkout, complete payment using supported payment methods, and receive crypto to the configured destination.
This is suitable for wallets, dApps, Web3 apps, and partner platforms that want to offer fiat-to-crypto access without building their own fiat on-ramp infrastructure.
2. Onchain Payment APIs
Onchain Payment APIs allow merchants and partners to accept crypto payments through Binance Pay Onchain. Users can pay with supported Binance balances, and the payment can be sent onchain to a merchant-controlled wallet or supported settlement destination.
This is suitable for merchants and platforms that want to accept crypto payments while keeping settlement outside a Binance merchant account structure where applicable.
3. Merchant Payout to Binance Account APIs
Merchant Payout to Binance Account APIs allow platforms to simplify crypto payouts to a user's Binance account.
With user authorization, Binance provides the relevant Binance deposit address to the partner. The partner can then pre-fill or route the payout to the correct Binance account destination, reducing manual address entry and wrong-network risk.
Binance does not initiate the merchant's payout transaction through this capability. The merchant or partner remains responsible for executing the onchain transfer and handling payout status, fees, risk controls, and reconciliation on its own side.
Configuration and add-on capabilities
Hosted Ramp & Onchain Payment APIs may also support configuration options such as Smart Convert Top-Up, Buy Any Token / Swap, checkout behavior, supported assets, supported networks, payment method configuration, and partner display settings.
Some capabilities are customized or approval-based. Availability depends on partner type, region, commercial setup, compliance review, and product enablement.
