+## 2026-06-19 — TON inbound `inTxs[].hash` now an explorer-ready hex hash
+
+**Behavior change** — `GET /requests/v2`: for TON-origin requests, `data.inTxs[].hash` is now the bare 64-character hex transaction hash, suitable for opening on Tonviewer at `/transaction/{TX_HASH}`. Previously this field returned an internal composite identifier that had to be parsed before it could be linked to an explorer. Non-TON origins and `data.outTxs[]` are unaffected.
+
+**Added** — `GET /chains`: the TON entry now exposes `explorerPaths.transaction` as `/transaction/{TX_HASH}`, so clients building explorer URLs can read the canonical Tonviewer path from the API rather than hardcoding `/tx/{TX_HASH}`.

 ## 2026-06-10 — Reorged deposit transactions report `failure` on `inTxs[]`
 
 **Behavior change** — `GET /requests/v2`: when a deposit is detected as reorged out or canonically failed on Base, the matching entry in `data.inTxs[]` now reports `status: "failure"`. Previously the top-level request `status` could flip to `"failure"` while the corresponding `data.inTxs[].status` remained `"success"`, leaving integrators that key their deposit UI off `data.inTxs[0].status` showing a succeeded deposit. Historical rows are not backfilled; the new behavior applies to detections going forward.
