| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Account surface | which Coinbase product controls the transfer path | identify Exchange, Prime portfolio or Prime Onchain Wallet first | cross-product account mapping |
| Destination set | the approved or whitelisted withdrawal destinations | confirm the exact address book before transfer | hidden legacy entries |
| Approval model | 2FA toggle, consensus approval or onchain policy governance | match approvals to organization roles | private role assignments |
| Waiting period | the time before a new address or disable action becomes effective | plan transfers around the documented timer | account-specific security review |
| Network scope | whether an address applies to one network or compatible networks | verify asset and network together | future network support |
| Onchain policy | Prime Onchain-specific transaction policies and browser extension use | separate onchain policies from vault rules | policy inheritance |
| Deletion and edits | how address changes are approved or removed | record non-secret change evidence | historical approval state |
| User role | who can initiate or approve address changes | check administrator and trader authority | private organization permissions |
| Evidence packet | official URL, date, setting name and non-secret destination label | avoid balances and full personal data | support-case privacy |
| Stop rule | when address governance is not decision-quality | stop if wallet type, address book or approval route is unclear | future UI changes |

实用结论
本文最有价值的地方是克制。Coinbase 公开了三种不同的地址治理入口，不能把它们合并成一个笼统的“提现安全”主张。Coinbase Exchange 的 whitelisting 会把提现限制到 Address Book 条目，首次启用后有 8 小时窗口，随后新地址和关闭白名单都涉及 48 小时 hold。Coinbase Prime 的 Trusted Address Book Protection 对 portfolio 自动启用，并通过 consensus approvals 处理更新。Coinbase Prime Onchain Wallet 还有独立的 Onchain Trusted Address Book，Destination Protection 默认开启，变更由 General Consensus 设置治理。决策关键是先确认哪一个钱包、账户类型和审批模型控制转账。 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。
