Original release notes
4.20.0
Minor Changes
- #21206
750bdd4Thanks @RobinVncnt! - Add mobile E2E for the post-onboarding hub mock flow (LIVE-31323).
- #21042
d5e1c7dThanks @ooke-ledger! - Tell the two Hyperliquid account-picker states apart.
The perps receiving step used one description for both states, so users who already had a Hyperliquid account were told to add one. It now reads "Select an account you want to deposit funds into to place your trades" when accounts exist, and keeps "To fund your perps, you need a Hyperliquid account.
- #21515
7f4723cThanks @sarneijim! - Bump Segment analytics SDKs for retry, rate-limit and security fixes (LIVE-35839)
- #21237
db835f9Thanks @vpenskyi-ledger! - Remove native navbar title on Select Quote page in Swap wallet40 header
- #21355
fc74af8Thanks @semeano! - Offer the Zcash memo only to shielded recipients. A memo travels in a shielded output, so a transparent recipient could never receive one, yet the send flow showed the input for every Zcash address and made the user fill or skip it. Send descriptors can now distinguish static memo support from recipient-specific visibility, and a memo left over from an earlier shielded recipient is dropped when the recipient turns transparent, so it can no longer reach the transaction builder.
- #21421
3d23fd4Thanks @tonykhaov! - Add a first-time verify hint on mobile Pay Request, persisted once dismissed.
- #21434
b7f83a1Thanks @tonykhaov! - Add persisted Pay Request verify-hint state in@features/flow-pay-request.
- #21367
d182d46Thanks @claudiiafg! - Fix the Ledger Sync entry point from Contacts: align the introduction copy and artwork with the production design, only show it when the user actually tries to add a contact or an address, start the flow on "Choose your sync method", and return to Contacts instead of the Portfolio once the flow is done on Mobile.
- #21470
5b79eb3Thanks @claudiiafg! - Fix the Contacts add address flow stalling on Continue by only offering networks the device can register an address on: EVM networks running their own coin app, such as Ethereum Classic, Sonic and Sei, are no longer selectable
- #21431
c06bd2eThanks @claudiiafg! - Fix the extra left padding on the address field of the Mobile add address and edit address drawers. Both screens render the address without the "To:" prefix, but Lumen's AddressInput mounts its prefix even when empty, so the prefix still took a slot in the field's inner gap and pushed the address 8px to the right. Add address now drops that gap and keeps the spacing only between the address and the trailing QR code icon, and edit address, which has no trailing icon, uses a plain TextInput instead.
- #21543
eea933cThanks @claudiiafg! - Fix the trash icon of the contact "Delete contact" action rendering white instead of red.
- #21587
46b51ddThanks @claudiiafg! - Fix the Contacts feature introduction so closing it counts as seen and keeps you on the Contacts list, instead of navigating back and reopening the introduction on the next visit.
- #21592
9e0d7ebThanks @koda-apps! - Fix misaligned "Maybe later" link on the notifications opt-in prompt drawer
- #21393
406f56fThanks @RobinVncnt! - Align the content card tag and dismiss cross with their desktop counterparts by using the Lumen UI Tag and InteractiveIcon components.
- #21026
4f514c9Thanks @LucasWerey! - Store a scrypt verifier instead of the password itself. Confirming a password now derives a digest and persists{version, scrypt, salt, digest}in the keychain, so nothing that can be replayed as a password is kept anywhere.
The protection state lands with it: two independent flags plus a session lock, keyed off "any protection is enabled" rather than on having a password, which is the coupling that makes biometrics-only impossible today.
Ordering is the safety argument throughout - the whole verifier is one keychain item, so an interrupted write leaves the previous verifier or none, never a half-written pairing, and the state flips only once the write has landed. Derivations are serialised: two concurrent setups would otherwise interleave and store a verifier whose salt belongs to the other run.
The password field also gains a length cap. It sits far above anything anyone types, and exists because deriving a digest is deliberately slow.
- #21746
c2e2276Thanks @amaslakov! - Add the error message shown when the protocol refuses a Tezos stake amount as too small
- #21401
8c40cc1Thanks @claudiiafg! - Skip the extra confirmation modal when editing a contact or address name. Apply changes now starts the device action directly when needed, and the Apply CTA shows the Ledger logo in that case.
- #21440
0089a4bThanks @claudiiafg! - Drive Contacts add-address confirmation through the Device Intent Executor instead of mocked Continue screens, including prefill and Send entry points.
- #21599
e601584Thanks @LucasWerey! - Pin the Contacts feature introduction CTA to the bottom of the mobile sheet
- #21277
37dde9fThanks @sarneijim! - Log Segment identify calls (enqueued or failed) in the mobile analytics debug overlay
- #21606
000eac0Thanks @LucasWerey! - Fix missing 8px spacing between items in the mobile contacts list
- #21526
4494817Thanks @tonykhaov! - Open the contact address sheet from the Pay strip and continue to MAD with the chosen recipient.
- #21418
60ee73cThanks @liviuciulinaru! - RenameCARD_API_URLtoCARD_BAANX_API_URL, keep the production defaults, and drop the Env vars section from the Card / Pay DevTool.
- #21551
727b9e5Thanks @mcayuelas-ledger! - Register and persist the card onboarding widget state in Ledger Wallet Mobile.
- #21610
6b47659Thanks @mcayuelas-ledger! - Add native card onboarding widget on mobile with Apple/Google Pay step and wallet persistence
- #21619
23d2e1eThanks @LucasWerey! - Keep mobile contact address detail action buttons full width by applying horizontal padding only to the summary.
- #21248
9672658Thanks @OlivierFreyssinet! - Edit an external address on the device from Contacts. The device intent now calls@ledgerhq/device-contacts-kit'sContactsManager.editExternalAddressIdentifier()andContactsManager.editExternalAddressScope(), each returning the rotated address proof to persist while the group's name proof passes through untouched, and both apps render the confirmation step and oneInfoStateper failure.
The device serves address and label edits as two separate commands, so an edit changing both asks the user to confirm twice, showing the same waiting screen for each step rather than numbering them. Nothing partial is ever stored: an abandoned or rejected edit leaves the record untouched, and a retry restarts the whole chain.
- #21609
094e919Thanks @LucasWerey! - Use the horizontal more icon on the mobile contact detail page
- #21247
a55d4caThanks @OlivierFreyssinet! - Rename a contact on the device from Contacts. The device intent now calls@ledgerhq/device-contacts-kit'sContactsManager.renameContact(), which returns the rotated name proof to persist, and both apps render the confirmation step and oneInfoStateper failure. A rejection keeps the job open so the user can retry on the same device.
Rename is a blockchain-agnostic dashboard operation, so it initializes on the dashboard (BOLOS) rather than a coin app: a contact with no address is renameable, and an outdated device surfaces as an OS-update screen instead of an app-update one.
- #21351
51c44ebThanks @OlivierFreyssinet! - Wire the contacts device intents in the remaining add address flows: adding an external address from the new send flow now goes through the Device Intent Executor instead of the mocked device intents port. The calling drawer closes so the executor can take the queue, and the add address flow closes as it hands the review over to the device
- #21833
8993c24Thanks @koda-apps! - Fix walletsync feature flags (lldWalletSync, llmWalletSync) to default to the PROD environment instead of STAGING.
- #21490
c5dfbedThanks @dilaouid! - fix(send): picking a contact on the recipient step now goes straight to the amount step, matching desktop
- #21487
b7d0367Thanks @gre-ledger! - DropdisableCountervaluefromCryptoCurrency. Nothing read it on a crypto currency; it stays onTokenCurrency, where the assets API drives it, and onFiatCurrency.
