自托管钱包恢复与 Passkey 披露雷达
已验证事实边界
1. Coinbase says a self-custody wallet gives direct control and that the recovery phrase should be stored carefully and kept confidential. 2. Coinbase says if a recovery phrase is lost for a self-custody wallet, no one can help recover access. 3. Coinbase Wallet describes smart wallet, email/social log-in wallet and mnemonic wallet types with different recovery implications. 4. Coinbase Wallet says some smart and mnemonic wallets cannot be recovered if the passkey or recovery phrase is lost. 5. Kraken account-creation guidance uses official-site verification, email/password entry and activation before the account is ready.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Product type | exchange account, smart wallet, CDP wallet or mnemonic wallet | name the product before discussing recovery | ambiguous marketing copy |
| Secret material | recovery phrase, passkey or platform credential | never store seed words in content or support chats | malware on device |
| Support path | who can help after loss | separate platform reset from private-key recovery | manual review outcome |
| Activation proof | email activation or wallet creation state | confirm official domain before entering data | phishing lookalikes |
| Wallet count | multiple wallets under one app | label active wallet and network | wrong active wallet |
| Network scope | EVM, Solana, Bitcoin or unsupported chain | match chain support to wallet type | network deprecation |
| Recovery test | dry-run understanding without exposing phrase | test with non-secret steps only | false confidence |
| Incident response | lost passkey, lost phrase or compromised email | have a written response plan | irreversible onchain transfer |
| Disclosure quality | whether documentation states what cannot be recovered | prefer explicit warnings over vague assurances | later doc changes |
| Radar score | practical ability to recover, migrate or prove control | score by evidence, not brand familiarity | account-specific blocks |

不是。本文是来源映射和操作核验清单，不建议买入、卖出、质押、存入、提现、迁移、持有、借贷或代币化任何资产。
实用结论
本文最有价值的地方是克制。交易所账户与自托管钱包的恢复表面不同。Coinbase 称交易所账户由平台管理私钥并可通过账户方式恢复，而自托管钱包依赖用户自己的密钥或恢复短语；Coinbase Wallet 又进一步区分 smart wallet 的 passkey、邮箱/社交登录钱包的账户式恢复，以及助记词钱包的恢复短语。Kraken 账户开设则使用邮箱激活并在后续完成验证以获得交易所访问。NexuAlpha 的雷达结论是：任何恢复能力声明，都必须先说明产品类型，否则不能被用户信任。 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。
