稳定币付款支持披露雷达：预览访问、收款人范围与转账控制
已验证事实边界
1. Stripe documentation labels stablecoin payouts for Connect as private preview. 2. Stripe documentation says stablecoin payouts start with USDC and that the platform balance stays in fiat while Stripe handles conversion and payout. 3. Stripe documentation says platforms must request access and complete additional requirements before using stablecoin payouts. 4. Stripe documentation says users link a crypto wallet through Express Dashboard and can receive payouts to that wallet instead of a bank account. 5. Stripe documentation says stablecoin payouts require the Transfers API. 6. A payout support disclosure should not imply universal country, company, nonprofit, New York, Hawaii or account-level availability without current eligibility evidence.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Preview access | private preview means public docs do not prove account entitlement | record approval state before building user-facing claims | future GA timing or changed access rules |
| Platform country | support depends on platform eligibility and country constraints | check platform country and unsupported states before launch copy | changes to regional support lists |
| Recipient type | recipient scope can exclude companies or nonprofits in the current documented state | separate individual, sole proprietor and entity recipients | private exceptions granted by support |
| Wallet linking | wallet setup belongs in the official dashboard flow | avoid collecting wallet credentials or recovery phrases outside Stripe | user support screenshots with private wallet data |
| Transfer API | stablecoin payout execution still depends on transfer creation and balance accounting | reconcile transfer ID, connected account and currency path | network-level settlement timing after payout initiation |
| Fallback rail | unsupported users need a non-crypto payout alternative | document bank payout fallback before enabling stablecoin preference | platform-specific operational support burden |
| Stop rule | pause when account approval, recipient scope or wallet path is not verified | do not advertise a payout method before the dashboard confirms availability | future private-preview policy changes |

控制说明
1. Preview access
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：private preview means public docs do not prove account entitlement。可执行动作是：record approval state before building user-facing claims。仍然未知的是：future GA timing or changed access rules。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、恢复保证、结算保证、可用性保证、价格暗示或平台排名。
2. Platform country
这里的含义是：support depends on platform eligibility and country constraints。可执行动作是：check platform country and unsupported states before launch copy。仍然未知的是：changes to regional support lists。
操作测试也必须很窄。这就是本节保留边界的原因。
3. Recipient type
这里的含义是：recipient scope can exclude companies or nonprofits in the current documented state。可执行动作是：separate individual, sole proprietor and entity recipients。仍然未知的是：private exceptions granted by support。
操作测试也必须很窄。这就是本节保留边界的原因。
4. Wallet linking
这里的含义是：wallet setup belongs in the official dashboard flow。可执行动作是：avoid collecting wallet credentials or recovery phrases outside Stripe。仍然未知的是：user support screenshots with private wallet data。
操作测试也必须很窄。这就是本节保留边界的原因。
5. Transfer API
这里的含义是：stablecoin payout execution still depends on transfer creation and balance accounting。可执行动作是：reconcile transfer ID, connected account and currency path。仍然未知的是：network-level settlement timing after payout initiation。
操作测试也必须很窄。这就是本节保留边界的原因。
6. Fallback rail
这里的含义是：unsupported users need a non-crypto payout alternative。可执行动作是：document bank payout fallback before enabling stablecoin preference。仍然未知的是：platform-specific operational support burden。
操作测试也必须很窄。这就是本节保留边界的原因。
7. Stop rule
这里的含义是：pause when account approval, recipient scope or wallet path is not verified。可执行动作是：do not advertise a payout method before the dashboard confirms availability。仍然未知的是：future private-preview policy changes。
操作测试也必须很窄。这就是本节保留边界的原因。
仍需明确的未知项
- future GA timing or changed access rules
- changes to regional support lists
- private exceptions granted by support
- user support screenshots with private wallet data
- network-level settlement timing after payout initiation
- platform-specific operational support burden
- future private-preview policy changes
实用结论
稳定币付款支持应被核验为 product eligibility 与 transfer control 问题，而不是泛化的 crypto payout 承诺。Stripe 文档把 Connect stablecoin payouts 标注为 private preview，说明平台需要请求访问并完成尽调，还说明受支持平台通过 Transfers API 付款，收款人在 Express Dashboard 中连接 crypto wallet。实用结论是：在向用户宣传稳定币付款前，先记录 platform country、recipient type、dashboard access、USDC balance behavior、wallet-linking path、unsupported states 与 fallback payout rail。 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、回调、政策框架、结算路径或流动性头寸在任何未来条件下都能成功的承诺。
