chore(runway): cherry-pick fix(ramp): parse slip44 intent as native asset cp-7.61.0

[runway-github]

• fix(ramp): parse slip44 intent as native asset cp-7.61.0 (fix(ramp): parse slip44 intent as native asset cp-7.61.0 #23689)

Description

This PR adds slip44 wildcard matching support to the Deposit
useCryptoCurrencies hook, aligning it with the existing behavior in
the Aggregator flow.

Reason for change:
When navigating to the Deposit flow from the Asset Details page with a
native asset (e.g., ETH), the intent contains a wildcard asset ID like
eip155:1/slip44:.. However, the Deposit SDK returns native tokens with
specific slip44 coin types (e.g., eip155:1/slip44:60). The direct
string comparison was failing to match these, causing the native token
not to be pre-selected.

Solution:
Added fallback logic that parses the CAIP-19 asset ID and matches any
token with the same chainId and slip44 namespace when the direct
match fails. This mirrors the existing behavior in the Aggregator
useCryptoCurrencies hook.

Manual testing steps

Feature: Native token selection in Deposit flow

  Scenario: user navigates to Deposit from Asset Details with native token
    Given the user is on the Asset Details page for ETH (or any native token)
    And the Deposit flow is enabled for the user's region

    When user taps the "Buy" button
    Then the Deposit flow opens with ETH pre-selected as the cryptocurrency

Note

Adds slip44 wildcard matching in useCryptoCurrencies to pre-select native tokens, with comprehensive tests.

• Deposit:
  • Update useCryptoCurrencies to parse CAIP-19 and support slip44 wildcard matching for native assets when intent has slip44:., falling back to direct match and then first token.
  • Import parseCAIP19AssetId and use it to match native tokens by chainId and slip44 namespace.
• Tests:
  • Add cases covering slip44 wildcard selection (same/different chain), fallback when no native match, and preference of direct match over wildcard.

Analysis Summary

The changes are focused on the Ramp Deposit functionality, specifically the useCryptoCurrencies hook. This is a well-contained change with clear scope.

Changes Made

1. useCryptoCurrencies.ts (Implementation)

• Added case-insensitive comparison for asset IDs using toLowerCaseEquals
• Implemented slip44 wildcard matching logic for native assets (e.g., eip155:1/slip44:.)
• The slip44 wildcard allows matching any native asset on a chain when the specific asset reference is a wildcard
• Enhanced the token selection logic with fallback matching for intent-based asset selection

2. useCryptoCurrencies.test.ts (Tests)

• Added 4 comprehensive unit tests covering:
  • slip44 wildcard matching for native tokens
  • Different chain ID handling with slip44 wildcards
  • Fallback behavior when no match found
  • Preference of direct matches over wildcard matching

Impact Assessment

Affected Area: Ramps (On/Off-ramp features) - specifically the Deposit flow

• This hook is used in BuildQuote views for both Deposit and Aggregator flows
• The changes affect how crypto currencies are selected based on intent parameters
• 6 files import this hook (confirmed by related files analysis)

Risk Level: Medium because:

• Changes modify selection logic for crypto currencies in ramps flows
• While well-tested at unit level, E2E verification is prudent
• The slip44 wildcard matching is new functionality that affects native asset selection
• Could impact user experience when selecting tokens for deposits

Why SmokeRamps?

1. Changes are directly in the Ramps feature area (app/components/UI/Ramp/Deposit/)
2. E2E tests exist in e2e/specs/ramps/ that use the SmokeRamps tag
3. The tag description matches: "On/off ramp features, buy/sell"
4. The changes affect the deposit/buy flow specifically

Why not other tags?

• SmokeAssets: While this touches asset selection, it's specific to ramps context, not general asset management
• SmokeWalletPlatform: Not core wallet functionality
• SmokeCore: Not core wallet framework changes
• SmokeNetworkAbstractions: Uses CAIP19 but doesn't change network layer itself

Test Coverage Recommendation

The SmokeRamps tests should cover:

• Token selection flows in deposit/buy scenarios
• Native token handling
• Different network/chain scenarios
• Intent-based token pre-selection

The changes include comprehensive unit tests, so E2E verification through SmokeRamps should provide adequate confidence that the feature works end-to-end in real user scenarios.
