The transaction details sheet had no contact attribution at all: `hasSourceUser`/`hasDestinationUser` were hardcoded `false` behind a migration TODO, so a DashPay payment showed the counterparty's raw payment address while its own home row already read "Sent to Alice" with her avatar. Wire both flags to the SDK's DashPay payment history (`DashPayPaymentTxLookup`), which records the counterparty identity and the true direction at send/sync time, and render the counterparty the way Android's transaction result screen does: - the header shows the contact's avatar with the direction icon badged into its corner, at DashUIKit's badge-to-icon ratio, instead of the bare direction icon; - a "Sent to" / "Received from" row names the contact (owner-set alias first, their profile name or username underneath) and opens their profile on tap, standing in for the address group it replaces; - the home row's contact avatar keeps the direction as a corner badge instead of dropping it. A payment whose counterparty has no cached name stays a plain transaction with its address rows — an avatar over a truncated identity id says less than the address does. Also fix what the fee row says, which the same screen made obvious: - fees always render in DASH. The duffs fallback below 0.0001 DASH predates the Dash formatter carrying all 8 fraction digits, so "226 duffs" is now just 0.00000226 in the unit every other amount uses. - received transactions get a fee row too. Their inputs aren't ours, but the value of an input is knowable whenever the wallet holds the parent transaction it spends, so `RawTransactionInspector` now resolves outpoint values from stored parents — the same "connect the input to a known transaction" step that lets dashj show a fee on Android. - when even that fails, the row reads "Paid by sender" rather than a fabricated zero, and one Insight lookup fills in the real number. That lookup is narrow on purpose (received only, unknown fee only, once) because it sends a txid to a third party; it reuses the client the never-accepted-transaction check already talks to, now extracted as `InsightExplorerAPI`.

📝 WalkthroughWalkthroughThe PR adds a centralized Insight transaction API, improves transaction amount and fee resolution, and adds DashPay contact attribution, avatars, contact rows, profile navigation, and fee presentation to transaction details. ChangesTransaction details and explorer integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds contact attribution and fee recovery for received transactions, but the current fee fallback can crash on certain invalid or unrepresentable explorer values and can mislabel valid zero fees as “Paid by sender”; malformed successful responses are also conflated with empty data. These are bounded but concrete correctness and runtime issues, so merge should wait for fixes. Sequence Diagram(s)sequenceDiagram

Review follow-up on the fee work. `duffs(fromDash:)` fed a number chosen by a third party straight into `UInt64(_: Double)`, which traps — in release builds too — on NaN, on an infinity, and on anything past 2^64. A nonsense `fees` in an explorer response would have crashed the detail sheet instead of leaving one row unfilled. It is failable now, bounded by Dash's max supply: nothing above that is a fee. `localFeeDuffs` returned 0 both for "the fee is zero" and for "we could not work the fee out", so a received transaction that genuinely paid no fee would have claimed the sender paid it. Both it and the explorer value are optional now, and only the absence of any answer falls back to "Paid by sender" — which also lets a zero from the explorer be stored and shown rather than discarded. `InsightExplorerAPI.transaction` now returns an optional body instead of folding an unparseable one into an empty dictionary, so a caller can tell "the explorer said nothing usable" from "the explorer returned an empty object". The result itself stays non-nil on a 200 with a bad body: `explorerKnowsTransaction` only needs the status, and failing it there would refuse a transaction removal the explorer had in fact answered.
Marketing version 9.0.0 -> 9.0.1 and build 13 -> 1 across every target (dashwallet, dashpay, TodayExtension, WatchApp, WatchApp Extension), so all 20 MARKETING_VERSION and 28 CURRENT_PROJECT_VERSION entries stay in agreement.

The transaction details sheet had no contact attribution at all.
TxDetailModel.hasSourceUser/hasDestinationUserwere hardcodedfalsebehind a migration TODO, so a DashPay contact payment showed the counterparty's raw payment address — while the very home row you tapped to get there already read "Sent to Alice" with her avatar.The same screen also got two things wrong about the network fee:
Reference for the visual design is the Android
dash-wallettransaction result screen (transaction_result_content.xml+TransactionResultViewBinder).develop-oldcarried an earlier contact path, but it rendered the counterparty as a plain right-aligned label — there was no avatar design to restore.What was done?
Contact attribution.
hasSourceUser/hasDestinationUsernow derive from the SDK's DashPay payment history (DashPayPaymentTxLookup), which records the counterparty identity and the true direction at send/sync time. A newTxDetailModel.ContactPartycarries the counterparty for the view layer.Header. For a contact payment the icon slot shows the contact's avatar with the direction icon badged into its bottom-trailing corner, using the same badge-to-icon ratio and ring as
DashUIKit.TransactionView, so the header badge and the home row badge read as one token at their different sizes. The heading stays "Amount Sent" / "Amount received" (Android parity) — the contact is named once, in the row below.Info section. A "Sent to" / "Received from" row names the contact — owner-set alias first, with their profile name or DPNS username underneath when it adds something — and opens
ContactProfileSheeton tap. It stands in for the counterparty address group, which is dropped. Rows stay in source → destination order in both directions. A payment whose counterparty has no cached name is deliberately left as a plain transaction with its address rows: an avatar over a truncated identity id says less than the address does.Home row. A contact avatar takes the icon slot, which previously meant the direction was dropped entirely (
secondaryIconwas nil). It now moves into the corner badge, matching Android and the new header.Fee. Three related fixes:
RawTransactionInspectornow resolves outpoint values from stored parent transactions, not only from our own spent TXOs. This is the same "connect the input to a known transaction" step that lets dashj produce a fee on Android (Transaction.getFee()returns nil the moment one input value is unknown).0, and a single Insight lookup fills in the real number.InsightExplorerAPI. The explorer GET thatUnconfirmedTransactionRemoverhad inline is extracted and shared rather than copied, per the "never copy-then-adapt" guardrail.One decision worth a reviewer's opinion
The explorer fee fallback sends a transaction id to a third-party explorer when you open the details of a received transaction whose fee isn't locally derivable. Today the app only contacts an explorer on an explicit "View in Block Explorer" tap and in the stuck-transaction removal check. The call is deliberately narrow — received only, unknown fee only, once per sheet, and a failure changes nothing on screen — but it is a new automatic outbound request for a privacy-focused wallet. Happy to drop it and keep only the local computation if that trade isn't wanted.
