Binance、Coinbase 与 Kraken REST API 认证控制对比
本文正文暫以英文原文展示，翻譯版本需完成來源複核後再發布。
已验证事实边界
1. Binance publishes official developer documentation for Spot API request security. 2. Coinbase publishes official developer documentation for Exchange REST API authentication. 3. Kraken publishes official developer documentation for Spot REST authentication. 4. MEXC Spot API documentation describes API-key authentication and signed requests for private account and trade endpoints. 5. MEXC Futures integration guidance separates integration requirements from general public market-data access. 6. API comparison should separate read-only access, trading authority, signature construction, timestamp or nonce handling and secret storage.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Endpoint class | not every endpoint needs the same permission | classify public, account and trade requests | future endpoint changes |
| Signature input | venues sign different strings or payloads | use official docs, not memory, for signing rules | SDK abstraction behavior |
| Timestamp or nonce | replay protection varies by venue | record clock or nonce strategy | clock drift and retries |
| Permission scope | read-only may be enough for monitoring | grant least privilege by task | private account role mapping |
| Secret storage | secrets must stay outside articles and reports | store credentials only in private local secret paths | operator key rotation |
| Failure handling | auth failures can create order-state ambiguity | test with non-trading or sandbox paths when available | live risk-engine behavior |
| Stop rule | stop if signature, time, permission or storage is unclear | do not connect a live bot yet | venue-side account flags |

控制说明
1. Endpoint class
这一项要求读者先把公开来源翻译成操作规则。这里的含义是：not every endpoint needs the same permission。可执行动作是：classify public, account and trade requests。仍然未知的是：future endpoint changes。因此本文不会把未知部分包装成安全承诺、收益承诺、官方背书、审批保证、注册诱导、可用性保证或产品推荐。
2. Signature input
这里的含义是：venues sign different strings or payloads。可执行动作是：use official docs, not memory, for signing rules。仍然未知的是：SDK abstraction behavior。
3. Timestamp or nonce
这里的含义是：replay protection varies by venue。可执行动作是：record clock or nonce strategy。仍然未知的是：clock drift and retries。
4. Permission scope
这里的含义是：read-only may be enough for monitoring。可执行动作是：grant least privilege by task。仍然未知的是：private account role mapping。
5. Secret storage
这里的含义是：secrets must stay outside articles and reports。可执行动作是：store credentials only in private local secret paths。仍然未知的是：operator key rotation。
6. Failure handling
这里的含义是：auth failures can create order-state ambiguity。可执行动作是：test with non-trading or sandbox paths when available。仍然未知的是：live risk-engine behavior。
7. Stop rule
这里的含义是：stop if signature, time, permission or storage is unclear。可执行动作是：do not connect a live bot yet。仍然未知的是：venue-side account flags。
仍需明确的未知项
- future endpoint changes
- SDK abstraction behavior
- clock drift and retries
- private account role mapping
- operator key rotation
- live risk-engine behavior
- venue-side account flags
实用结论
本文最有价值的地方是克制。REST API 认证应按控制设计比较，而不是复制粘贴签名代码。Binance Spot API 文档通过开发者文档说明 request security；Coinbase Exchange 文档说明 REST API authentication；Kraken 开发者文档说明 Spot REST authentication。实用结论是：连接自动化交易前，应先映射哪些请求需要认证、签名输入是什么、是否使用 timestamp 或 nonce 语义、权限如何收窄，以及 secret 存放在哪里。本文不发布凭据，也不建议在只需只读数据时授予交易权限。 用户应获得一个更清楚的核验路径和停止条件，而不是一个看似肯定、实则无法由公开证据承担的承诺。
