场景

一家全球公司持有 USDC/USD 资金，需要同时向巴西 (BRL)、尼日利亚 (NGN) 和肯尼亚 (KES) 的承包商付款。

​
工作流程

​
1. 为主账户充值

使用加密资金库模式。公司（主账户）将资金存入其子账户以积累余额。 
curl -X GET "https://api.bullring.finance/v1/ramp/{subaccountId}/banking/deposits/crypto/ETH-MAINNET" \
  -H "Authorization: Bearer <YOUR_API_KEY>"

{
  "id": "f156b4cb-9b34-4c45-bed1-92576c703412",
  "address": "0x34e36e819b37577c66e7032e060866bd6a04e677",
  "chain": "ETH-MAINNET",
  "currency": "USDC",
  "addressTag": null,
  "createdAt": "2025-11-21T11:17:42.575Z"
}

​
2. 遍历并支付

循环遍历您的工资单并触发提款。 对于每位员工：
  1. 创建收款人（如果尚不存在）。
  2. 从主账户向收款人提款。
// 伪代码
const employees = [
  { id: "user_brazil", currency: "BRL", amount: 5000, pix: "[email protected]" },
  { id: "user_nigeria", currency: "NGN", amount: 300000, account: "1234567890" },
];

const MAIN_ACCOUNT_ID = "YOUR_TREASURY_SUBACCOUNT_ID";

for (const emp of employees) {
  // 1. 创建收款人
  // 调用 POST /v1/ramp/{MAIN_ACCOUNT_ID}/banking/recipients
  
  // 2. 提款
  // 调用 POST /v1/ramp/{MAIN_ACCOUNT_ID}/banking/withdrawals
}
