Binance CAAS KYC 子账户 API 限制与 Travel Rule 端点地图
已验证事实边界
1. Binance says CAAS subaccount Travel Rule requirements depend on the Binance entity the subaccount is tagged to, not only on registration country. 2. Binance says AU-tagged CAAS subaccounts require a Travel Rule questionnaire for deposits and withdrawals with no minimum threshold. 3. Binance says Travel Rule subaccounts should use the localentity withdrawal endpoint, while non-Travel-Rule entities should keep the capital withdrawal endpoint. 4. Binance says newly created non-KYC subaccounts cannot create API keys and retrieve deposit addresses before completing KYC. 5. Binance says deposits into older non-KYC subaccounts may be rejected and an appeal through the SAPI asset recovery API may take up to 30 days.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Entity tag | which Binance entity governs the subaccount | confirm the tag with the account manager | entity tag not visible from country alone |
| KYC status | whether the subaccount can receive deposits, trade or use APIs | record KYC state before issuing keys | customer-specific review result |
| Travel Rule trigger | whether extra originator or beneficiary fields are required | route tagged accounts through the correct endpoint | future threshold changes |
| Withdrawal endpoint | capital or localentity API path | choose the endpoint from entity status | integration fallback behavior |
| Master key | the key used for broker calls and withdrawals | separate master authority from trading keys | partner custody process |
| Subaccount key | the key used for trading and user streams | issue after wallet and KYC readiness | key created before product enablement |
| Deposit address | whether a subaccount can retrieve a funding address | do not fund until KYC state is proven | old saved addresses |
| Rejected deposit | legacy funding into a non-KYC account | preserve non-secret recovery evidence | asset recovery outcome |
| Webhook URL | the endpoint receiving KYC status updates | set a durable URL before submission | no-change path after submission |
| Stop rule | conditions where operations should pause | stop on unknown tag, missing KYC proof or endpoint mismatch | private account facts |

实用结论
本文最有价值的地方是克制。Binance 的 CAAS FAQ 把子账户运营变成实体归属、KYC 状态与端点路由问题。Binance 表示,Travel Rule 要求取决于子账户被标记到哪个实体;AU 标记账户的存入和提现均需要问卷且没有最低门槛,IN 标记账户在超过 1,000 美元门槛时适用 Travel Rule。文档还说明,非 Travel Rule 实体应继续使用 capital withdrawal endpoint,而被标记实体应迁移到 localentity withdrawal endpoint。对于 KYC 限制,新建未 KYC 子账户不能创建 API key 或获取充值地址,旧未 KYC 子账户的充值可能被拒绝,未 KYC 子账户也会受到交易和转账限制。安全结论是:先映射实体标签、KYC 状态、端点、API key 所有者与恢复路径,再把子账户当作可运营对象。 用户应获得一个更清楚的核验路径,而不是一个看似肯定、实则无法由公开证据承担的承诺。
