Summary

A Dash Platform identity id is 32 raw bytes; the string form is a presentation choice. Everywhere a user meets an identity id it should be base58 — that is what Platform explorers use, and what the app already reached for whenever it had a dedicated property for the job (ContactItem.identityIdBase58, the row model's idBase58, the dashpay://user QR payload). Hex belongs in logs, cache keys and interop payloads.

The gap was in the places that formatted an id inline instead of using those properties — including two inside the contacts and identities screens that otherwise render base58.

Four user-facing surfaces were still rendering hex, so the id shown in the app could not be compared against an explorer without decoding it by hand. This PR moves all four to base58 and leaves every non-display use of hex alone.

What changed

Surface Before After
SDKIdentityProfileSheet — "Identity ID" row 64-char hex base58
ShieldedActivityHistoryidentityCreate detail "Identity ID" row 64-char hex base58
ContactItem.displayTitle — last-resort fallback 8-char hex prefix 8-char base58 prefix
IdentitiesViewModel — unnamed identity row title 12-char hex prefix 12-char base58 prefix

Both prefix lengths are unchanged. base58 carries more entropy per character than hex, so the truncations stay at least as collision-resistant.

Why these were hex

The profile sheet said so in its own doc comment: it rendered hex "matching the existing coordinator logs". The format was inherited from log output rather than chosen for the reader. IdentitiesViewModel was internally inconsistent — the row model already carried idBase58 for the full id while the title fell back to identityIdString (hex). ContactItem built its own hex prefix four lines above an identityIdBase58 property whose comment already stated base58 is "the identity id as users see it elsewhere".

Deliberately unchanged

  • Logs (DWIdentityRegistrationCoordinator, contacts service)
  • UserDefaults / cache keys (DWCurrentUserIdentityInfo, SwiftDashSDKContactsService)
  • Identifiable conformances (ContactCandidate.id)
  • The raw Storage Explorer — left untouched pending a decision from whoever owns that screen

DWCurrentUserIdentityInfo.identityIdHex (@objc) lost its only caller when the profile sheet moved to base58, so the second commit removes the property, its Snapshot field and both construction sites — nothing in the app read it, in Swift or Obj-C. The hex local in rebuildSnapshot() stays, since the snapshot log line still prints its first 8 characters.

One follow-up is left out of scope. In the Storage Explorer, most rows label the format explicitly (ID (Hex), Owner ID (Hex), Contact ID (Hex)) while Identity ID, From, To and Performed By render hex without that qualifier. We assumed hex is deliberate there — it is a raw storage inspector — but did not verify that intent, so nothing was changed. Worth a look from whoever owns the screen: either the labels should be consistent, or those rows belong in base58 like the rest of the app.

Verification

Built clean against the dashpay scheme (ARCHS=arm64, iOS 26.5 simulator); each touched file confirmed recompiled with no new warnings.

Verified on device:

  • Profile sheet — the id matches the Identities list and resolves on Platform Explorer.
  • Shielded identityCreate row — displayed AY4heGwy…4RxvDfTS; the copied value is 44 characters, every character inside the base58 alphabet, decoding to exactly 32 bytes and round-tripping cleanly. No version byte, no checksum — plain base58, matching Data.toBase58String().

Not exercised at runtime: the two truncated fallbacks, which require a contact with no alias/display name/username and an identity with no name at all. Both are build-verified only.

Summary by CodeRabbit

  • Improvements
    • Identity IDs are now consistently displayed in Base58 format across contacts, profiles, identity lists, and shielded activity details.
    • Identity IDs shown in activity details remain shortened for readability and can still be copied.
    • Identity information continues to support avatar and top-up functionality.

A Dash Platform identity id is 32 raw bytes; the string form is a
presentation choice. Base58 is what a user meets everywhere else — on
Platform explorers, and wherever the app already had a dedicated
property for the job (`ContactItem.identityIdBase58`, the row model's
`idBase58`, the `dashpay://user` QR payload). Hex belongs in logs, cache
keys and interop payloads.

Four display sites formatted the id inline instead, and rendered hex:

- `SDKIdentityProfileSheet` — the "Identity ID" row, in a format its own
  doc comment said was chosen to match the coordinator logs.
- `ShieldedActivityHistory` — the `identityCreate` detail's copyable
  "Identity ID" row, same label and treatment.
- `ContactItem.displayTitle` — the last-resort fallback, building its own
  hex prefix four lines above `identityIdBase58`.
- `IdentitiesViewModel` — an unnamed identity's row title, truncating
  `identityIdString` (hex) while the same row model carried `idBase58`.

All four now render or truncate base58, so an id reads the same in the
app, in the `dashpay://user` payload and on an explorer. Prefix lengths
are unchanged (8 and 12 characters); base58 carries more entropy per
character, so the truncations stay at least as collision-resistant.

Logs, UserDefaults/cache keys and Identifiable conformances keep hex, as
does the raw Storage Explorer.

`SDKIdentityProfileSheet` was the only reader of
`DWCurrentUserIdentityInfo.identityIdHex`; moving that row to base58
left the property, its `Snapshot` field and the `@objc` surface with no
callers anywhere in the app — no Swift, no Obj-C, no dynamic lookup.

Remove the whole chain rather than document it as dead. The `hex` local
in `rebuildSnapshot()` stays: the snapshot log line still prints its
first 8 characters.

Also correct the `identityId` doc comment, which claimed Obj-C callers
use `identityIdHex`. They never did, and the property is gone now.

📝 Walkthrough

Walkthrough

Identity ID handling now preserves raw Data in identity snapshots and uses Base58 text across contact titles, profile details, wallet identity titles, and shielded activity displays. The public Objective-C hexadecimal accessor was removed.

Changes

Identity ID formatting

Layer / File(s) Summary
Identity data contract
DashWallet/Sources/Infrastructure/SwiftDashSDK/Identity/DWCurrentUserIdentityInfo.swift
Snapshot now stores raw identity ID data. The public identityIdHex accessor and hexadecimal snapshot conversion were removed.
Identity profile presentation
DashWallet/Sources/UI/DashPay/Profile/SDKIdentityProfileSheet.swift, DashWallet/Sources/Infrastructure/SwiftDashSDK/Contacts/ContactItem.swift, DashWallet/Sources/UI/Menu/Security/Wallets/IdentitiesViewModel.swift
Identity profile values, contact title fallbacks, and wallet identity title fallbacks now use Base58 text.
Shielded activity identity display
DashWallet/Sources/UI/Home/Views/ShieldedActivityHistory.swift
Created identity IDs now use Base58 encoding. The detail sheet reads the renamed createdIdentityIdBase58 property.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 75c5c

The change makes identity IDs consistently user-readable in base58 without altering non-display behavior. The only remaining issue is a trivial initializer cleanup, so no actionable merge-blocking risk remains.
