Networks & tokens

BchainPay supports four blockchain networks. Each network has a native coin and a set of stablecoin tokens. When you create a payment intent you specify a network and, depending on the network, a token.

Supported networks and tokens

Ethereum (ERC-20)

Address format: 0x… (40 hex characters)

BNB Chain (BEP-20)

Address format: 0x… (40 hex characters)

Solana (SPL tokens)

Address format: Base58-encoded public key

Tron (TRC-20)

Address format: T… Base58Check-encoded

How network and token work in the API

When creating a payment intent, pass network and token in the request body:

{
  "amount_cents": 5000,
  "network": "ethereum",
  "token": "USDT"
}

Valid network values: ethereum, solana, tron, bnbchain.

Token requirement rules

For solana and tron, specifying a token selects the corresponding SPL or TRC-20 contract. If you omit token, the payment is expected in the native coin (SOL or TRX).
