|---|---|---|---|
| Bank collateral | USD or T-BILL assets held with banking partners | identify the collateral record | bank-specific custody terms |
| Bybit liability | USDT financing or outstanding principal | separate bank asset from exchange liability | private loan balance |
| Haircut | adjusted value rather than face value | calculate with the documented haircut base | future haircut changes |
| Risk unit | the account group used for collateral and liability tests | map UTA and bank collateral together | account-specific risk-unit setup |
| Transfer ratio | whether assets can move out of the risk unit | check ratio before transfer | real-time risk-engine result |
| LTV threshold | initial, margin-call and liquidation levels | pre-plan response levels | market gap behavior |
| Notification | margin-call and alert route | do not rely on alerts as sole protection | delivery delay |
| Liquidation path | repayment, UTA assets and bank-collateral settlement sequence | know sequence before borrowing | settlement timing |
| Fee | liquidation fee treatment | include in worst-case planning | tax and accounting treatment |
| Stop rule | when RWA-style collateral is not decision-quality | stop if custody, haircut, LTV or transfer ratio is unknown | future product changes |

实用结论
本文最有价值的地方是克制。Bybit Bank Triparty 把抵押核验变成银行托管、haircut 和转账限制问题。Bybit 表示，该产品通过受监管银行合作伙伴保管 USD 与 T-BILL 抵押资产，同时允许用户在 Bybit 获得 USDT financing。帮助页把 risk-ratio LTV 定义为 outstanding principal 除以 haircut-adjusted bank collateral value，并描述 transfer-ratio 测试；当 Transfer Ratio 低于 15% 时，risk unit 内 Unified Trading Account 向其他账户转出抵押资产可能被限制。文档还列出 initial、margin-call 和 liquidation LTV 水平，以及 liquidation fee。决策结论是：在把 T-BILL-backed collateral 当作类现金流动性之前，先映射银行抵押、Bybit 负债、haircut、risk unit、transfer ratio、通知路径和清算顺序。 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。
