控制说明

1. Key material

这一项要求读者把公开来源翻译成操作规则。这里的含义是：Binance examples may depend on Ed25519 while Coinbase private calls rely on JWT bearer authentication。可执行动作是：store key type, signing library, rotation date and permission scope separately for each venue。仍然未知的是：whether a private account can use the same key format across all products。因此本文不会把未知部分包装成收益承诺、牌照承诺、审批保证、安全保证、恢复保证、平台排名或价格暗示。

2. Session state

这里的含义是：authenticated WebSocket sessions create liveness and reconnect requirements。可执行动作是：test logon, status, subscribe, reconnect and duplicate event handling under packet loss。仍然未知的是：how each venue behaves during incident recovery or partial outage。

操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。

3. Permission scope

这里的含义是：a valid credential can still lack user, order, portfolio or transfer permissions。可执行动作是：start read-only and promote only the smallest permission needed for the channel。仍然未知的是：whether future API portal changes alter permission labels。

操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。

4. Fallback design

这里的含义是：REST snapshots and WebSocket event streams may disagree during reconnects。可执行动作是：write a reconciliation rule that names source of truth, retry window and cancel threshold。仍然未知的是：which data gap is acceptable for a given strategy。

操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。

5. Evidence retention

这里的含义是：debugging auth failures often tempts teams to capture secrets。可执行动作是：record only endpoint, method, non-secret request id, status and timestamp。仍然未知的是：whether support will need private evidence outside the article boundary。

操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。

仍需明确的未知项

• whether a private account can use the same key format across all products
• how each venue behaves during incident recovery or partial outage
• whether future API portal changes alter permission labels
• which data gap is acceptable for a given strategy
• whether support will need private evidence outside the article boundary

实用结论

Binance 和 Coinbase 都支持程序化交易流程，但 WebSocket 认证控制不能混用。Binance 文档把开发者引向 authenticated WebSocket sessions、部分 user-data stream 方法中的 Ed25519 key、官方接口边界和产品级 rate limits。Coinbase Advanced Trade 文档则围绕 Coinbase App APIs、JWT bearer token 与 permissioned endpoints 描述 WebSocket feed 和 REST endpoint。可执行决策是：生产接入 private order 或 account events 前，先测试 key type、session lifetime、channel scope、permission scope、reconnect behavior 与 read-only fallback。 本文停在证据边界内，帮助读者决定下一步核验什么，而不是把公开文档改写成私人账户、钱包、API key、池子路径、稳定币余额、代币化资产或政策框架在任何未来条件下都能成功的承诺。
