+## 2026-05-27 — `depositAddress` payloads add `depositTxHash`
+
+**Added** — `GET /requests/v2` and the `request.status.updated` webhook/websocket event: the `depositAddress` object now includes `depositTxHash`, the origin-chain transaction hash of the depositor's transfer into the deposit address. This is distinct from `inTxHashes`, which tracks the sweep from the deposit address to the Relay depository. The field is `null` until the depositor's transfer is observed, and is omitted on non-deposit-address requests (where `depositAddress` itself is `null`).
+
 ## 2026-05-26 — Webhook payload adds `details`, `failReason`, `refundFailReason`
 
 **Added** — `request.status.updated` webhook: the `data` object now includes `details`, `failReason`, and `refundFailReason`, matching the corresponding fields on [`GET /intents/status/v3`](/references/api/get-intents-status-v3). `failReason` returns `"N/A"` on non-failure statuses and the recorded reason (or `"UNKNOWN"`) on `failure`/`fallback`/`refund` statuses. `refundFailReason` defaults to `"N/A"` when no refund-leg failure is recorded. `details` is `null` when no additional context is available.
