Multi-Chain Support

RazCrypto supports BSC, Ethereum, Polygon, and VDChain networks with stablecoins and native coins.

Supported Networks

Chain	Tokens	Standard	Speed	Min Amount
BSC	USDT, USDC, DAI, BNB	BEP-20 / Native	2-3 sec	0.01 USDT
Ethereum	USDT, USDC, DAI, ETH	ERC-20 / Native	3-5 sec	0.01 USDT
Polygon	USDT, USDC, DAI	ERC-20	2-4 sec	0.01 USDT
VDChain	USDT, VDC	VDC-20 / Native	~3 sec	0.01 USDT

Stablecoins vs Native Coins: Stablecoins (USDT, USDC, DAI) are pegged to $1. Native coins (BNB, ETH, VDC) have variable prices — amount must be specified in coin quantity, not USD.

Activation Required: Each chain must be activated in Dashboard → Receive Wallet before accepting payments.

Stablecoin Payments (Hosted Checkout)

For hosted checkout page, only stablecoins are supported. Native coins require custom integration.

Native Coin Payments (API Only)

Native coins are supported via API only. You must specify the exact coin amount (not USD value). Convert price using a price API before creating payment.

Important: Native coin payments are NOT available on hosted checkout page. Build your own checkout UI when using native coins.

// Example: Accept 0.01 BNB payment
curl -X POST "https://razcryptogateway.com/api/v2/payments/create" \
  -H "X-Public-Key-Id: rz_pub_your_key" \
  -H "Content-Type: application/json" \
  -d '{"amount": 0.01, "chain": "BSC", "currency": "BNB", "return_json": "true"}'

// Example: Accept 0.005 ETH payment
curl -X POST "https://razcryptogateway.com/api/v2/payments/create" \
  -H "X-Public-Key-Id: rz_pub_your_key" \
  -H "Content-Type: application/json" \
  -d '{"amount": 0.005, "chain": "ETH", "currency": "ETH", "return_json": "true"}'

// Example: Accept 10 VDC payment
curl -X POST "https://razcryptogateway.com/api/v2/payments/create" \
  -H "X-Public-Key-Id: rz_pub_your_key" \
  -H "Content-Type: application/json" \
  -d '{"amount": 10, "chain": "VDCHAIN", "currency": "VDC", "return_json": "true"}'
