출처 검증 리서치: Coinbase Advanced Trade Websocket
본문은 검증된 영어 원문으로 표시됩니다. 번역본은 출처 검토 후 추가됩니다.
Verified Fact Boundary
1. Coinbase Advanced Trade WebSocket documentation describes setup, authentication and subscription workflows for Advanced Trade WebSockets. 2. Coinbase List Accounts API reference documents an authenticated endpoint for retrieving account information. 3. Coinbase Advanced Trade Portfolios documentation says portfolios can segregate strategies and that API keys can be scoped to portfolio resources. 4. Coinbase Create Portfolio API reference documents a portfolio endpoint requiring authorization. 5. Together, these sources support a checklist for account-channel scope, authorization and reconciliation rather than a blanket claim that every key can access every account. 6. These sources do not prove a private account can create portfolios, trade every product, avoid compliance review, bypass region rules or recover from an integration failure.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Channel purpose | market data, account data and order workflows have different risk | name the channel purpose before subscribing or storing messages | whether a channel emits account-specific data under every portfolio state |
| Portfolio scope | portfolio boundaries can segment strategies and API-key resource access | map key, portfolio, account and strategy owner before production use | whether a portfolio deletion or scope change leaves stale automation |
| Authorization path | private endpoints require bearer-token or key-based authorization | document token generation method without storing secrets in reports | whether a token library upgrade changes the signed URI or header behavior |
| Reconnect plan | private sockets need recovery rules after disconnects | define replay, resubscribe, sequence check and authoritative REST reconciliation | whether messages were missed while the socket was down |
| Evidence stop rule | a passing local socket test is not a production permission claim | record source URL, access time, channel, non-secret error and stop condition | whether private account controls narrow or expand what the public docs imply |

Control Notes
1. Channel purpose
Channel purpose is the point where public documentation must become an operating rule. In this package, it means market data, account data and order workflows have different risk. The practical action is to name the channel purpose before subscribing or storing messages. The unresolved edge is whether a channel emits account-specific data under every portfolio state, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.
2. Portfolio scope
Portfolio scope is the point where public documentation must become an operating rule. In this package, it means portfolio boundaries can segment strategies and API-key resource access. The practical action is to map key, portfolio, account and strategy owner before production use. The unresolved edge is whether a portfolio deletion or scope change leaves stale automation, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.
The operating test is narrow.
3. Authorization path
Authorization path is the point where public documentation must become an operating rule. In this package, it means private endpoints require bearer-token or key-based authorization. The practical action is to document token generation method without storing secrets in reports. The unresolved edge is whether a token library upgrade changes the signed URI or header behavior, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.
The operating test is narrow.
4. Reconnect plan
Reconnect plan is the point where public documentation must become an operating rule. In this package, it means private sockets need recovery rules after disconnects. The practical action is to define replay, resubscribe, sequence check and authoritative REST reconciliation. The unresolved edge is whether messages were missed while the socket was down, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.
The operating test is narrow.
5. Evidence stop rule
Evidence stop rule is the point where public documentation must become an operating rule. In this package, it means a passing local socket test is not a production permission claim. The practical action is to record source URL, access time, channel, non-secret error and stop condition. The unresolved edge is whether private account controls narrow or expand what the public docs imply, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, safety guarantee, recovery promise, platform ranking or price implication.
The operating test is narrow.
Known Unknowns
- whether a channel emits account-specific data under every portfolio state
- whether a portfolio deletion or scope change leaves stale automation
- whether a token library upgrade changes the signed URI or header behavior
- whether messages were missed while the socket was down
- whether private account controls narrow or expand what the public docs imply
Practical Takeaway
Coinbase Advanced Trade WebSocket work should be treated as account-channel change control, not as a simple market-data socket. Coinbase documentation describes Advanced Trade WebSocket setup, authentication and subscriptions, account-listing endpoints, and portfolio behavior where API keys can be scoped to portfolios. The practical update is to record channel purpose, portfolio scope, bearer-token generation path, read-versus-trade need, reconnect plan, message reconciliation and non-secret evidence before account data or order workflow code is promoted. The article stops at the evidence boundary. It helps the reader decide what to inspect next without converting public documentation into a promise that a private account, wallet, API key, pool route, stablecoin balance, tokenized asset or policy framework will work under every future condition.
