Important

Draft, stacked on #5727. The base is #5727's branch, so the diff shows only this PR's two commits. It retargets to v5.1-dev once #5727 merges.

Do not merge before dashpay/dashwallet-ios#1299. This PR deletes Swift KeyWallet API that dashwallet-ios develop still uses. That PR moves the app to the helpers #5727 adds.

Issue being fixed or feature implemented

dashpay/rust-dashcore#776 deletes key-wallet-ffi and the ffi feature of dash-network. Once apps use the platform-wallet-ffi helpers from #5727, nothing in Platform calls key-wallet-ffi any more. This PR removes the dependency, so Platform can bump rust-dashcore past dashpay/rust-dashcore#776 (the draft on top of this one).

What was done?

  • refactor(sdk)!: drop the key-wallet-ffi dependency:
    • rs-unified-sdk-ffi no longer links key-wallet-ffi, and build_ios.sh no longer ships its header. refactor(sdk)!: move the KeyWallet helpers to platform-wallet #5727 already removed it from rs-unified-sdk-jni.
    • The Swift KeyWallet classes that only wrapped it are deleted: Wallet, WalletManager, the account, address pool and transaction classes, KeyWalletError, Mnemonic.toSeed and wordCount, Address.getType, and the KeyDerivation path builders, parsePath, createMasterKey and extended key classes.
    • These stay: Mnemonic (generate, validate, walletId, firstReceiveAddress, the wordlist helpers), KeyDerivation.getIdentityAuthenticationPath, Address.validate, TransactionDecoder, KeyManager and the plain Swift types.
    • Tests that used the deleted classes now derive through platform_wallet_derive_ext_priv_key_from_mnemonic, read addresses from a throwaway PlatformWalletManager, or check fixed wallet id and address vectors.
  • refactor(sdk): define FFINetwork in rs-sdk-ffi: FFINetwork came from dash-network behind the ffi feature that chore: remove FFI layer rust-dashcore#776 removes. rs-sdk-ffi now defines the enum and its Network conversions, and every other FFI crate takes it from there. The generated C definition is unchanged (FFINetwork_Mainnet and so on), so Swift and Kotlin need no code change. build_ios.sh stops shipping dash-network.h, and the unused dashcore_network_get_name export goes with it.

How Has This Been Tested?

Platform CI does not run the Rust, Swift and Kotlin jobs for a draft or for a PR whose base is not a v*-dev branch, so these ran locally, all green:

  • cargo fmt --all -- --check and cargo clippy --workspace --all-features --all-targets -- -D warnings
  • cargo test -p platform-wallet -p platform-wallet-ffi -p rs-sdk-ffi -p rs-unified-sdk-jni -p rs-unified-sdk-ffi --lib
  • Swift SDK: build_ios.sh --target mac and --target sim, then swift test --filter SwiftDashSDKTests (882 tests, 1 skipped, 0 failures)
  • Kotlin SDK: ./gradlew :sdk:testDebugUnitTest

Breaking Changes

The deleted Swift KeyWallet classes and methods are no longer part of SwiftDashSDK. Apps move to PlatformWalletManager, Mnemonic.walletId(for:network:), Mnemonic.firstReceiveAddress(for:network:), and ManagedPlatformWallet.findBIP44AddressPath(address:) and bip44AddressPrivateKey(address:storage:). The C and JNI interfaces apps call are unchanged.

Walkthrough

The change defines FFINetwork in rs-sdk-ffi, removes Swift KeyWallet wrappers and related FFI dependencies, updates JNI network imports, and changes Swift tests to use platform-wallet APIs.

Changes: FFI network contract

Layer / File(s) Summary
Centralize the FFI network contract
packages/rs-sdk-ffi/*, packages/rs-platform-wallet-ffi/*, packages/rs-unified-sdk-ffi/*, Cargo.toml, Kotlin and Swift network references, book/src/contributing/coding-conventions.md
rs-sdk-ffi defines FFINetwork with fixed values and conversions to and from Network. Related crates re-export this type and remove direct dash-network FFI dependencies. Documentation and Kotlin tests identify the new source.
Remove Swift KeyWallet APIs
packages/swift-sdk/Sources/SwiftDashSDK/KeyWallet/*, packages/swift-sdk/Package.swift, packages/swift-sdk/CLAUDE.md, packages/swift-sdk/SwiftExampleApp/*
The Swift KeyWallet facade, wallet and account wrappers, derivation and transaction APIs, FFI-backed models, documentation, and example script are removed.
Update crate dependencies and JNI imports
packages/rs-unified-sdk-jni/*, packages/rs-unified-sdk-ffi/*, packages/swift-sdk/build_ios.sh
JNI network imports use FFINetwork from rs-sdk-ffi; existing integer-to-network mappings remain unchanged. The build script no longer includes the removed crate headers.
Update Swift tests to use platform wallet APIs
packages/swift-sdk/SwiftTests/SwiftDashSDKIntegrationTests/Core/*, packages/swift-sdk/SwiftTests/SwiftDashSDKTests/*
Tests replace KeyWallet-based address and key derivation with PlatformWalletManager or platform-wallet FFI calls. Mnemonic tests check reference master keys and pinned wallet IDs and addresses.

Explanation

The title "refactor(sdk): drop the key-wallet-ffi dependency" matches the main change. The PR removes the key-wallet-ffi dependency from the unified SDK FFI and deletes the Swift KeyWallet wrappers that relied on it. The title is short, specific, and follows a conventional commit style. It does not mention the breaking removal of the Swift KeyWallet API, but it does not need to cover every detail.

Full details: Docstring Coverage

Minor · Functional Correctness · Quick win

Reject NUL bytes in createWallet(mnemonic:) before the C-string conversion.

createWallet(mnemonic:) passes the phrase to Rust through withCString with no NUL check. Rust reads the phrase up to the first NUL, so a phrase with an appended NUL and junk creates a wallet from the valid prefix. The new masterKey helper and testGibberishStillThrows do not cover this input.

150-154: Trivial · Functional Correctness · Quick win

The original comment's wording "the same derivation code" is too strong. The two sides share the key_wallet BIP-32 library. They do not call one function. The finding is a test-coverage gap, not a defect in the production code. The original classification as a functional-correctness nitpick is too low for a pinned-vector gap on a signing key path. A recommended refactor label fits.
Pin the identity-authentication public key to a fixed vector.

derivePublicKey(path:) and the signing resolver both derive keys through the same key_wallet BIP-32 code. The row stores the helper's output as the expected key. A regression in that shared derivation therefore changes the expected key and the signing key together. Both tests still pass, and the only assertion on the key is its length.

Add a hard-coded compressed public key for the test mnemonic at the identity-authentication path that this test derives. Generate that value with an independent BIP-32 implementation, not with derivePublicKey, so the test does not check the code against itself. Assert the derived bytes against that constant.

222-228: Minor · Potential issue · Poor tradeoff

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The replacement for explicit address-range derivation only reads existing pool rows. If default-account creation does not eagerly persist ten external addresses, it cannot obtain the requested range.

The integration test fails with the address-count setup error instead of exercising wallet-history recovery.

This can occur when: A new throwaway wallet has a BIP-44 account but its external pool is populated lazily.

@coderabbitai re the NUL-byte finding on createWallet(mnemonic:): agreed, the phrase should be checked with KeyDerivation.requireNoNUL before the C-string conversion. This PR does not touch PlatformWalletManager.swift, so the gap already exists on v5.1-dev. The finding is anchored here only because the new tests call createWallet(mnemonic:). I filed it as #5758 to fix separately.

Tip

For best results, initiate chat on the files or code changes.

@xdustinface Agreed. The NUL-byte validation gap is valid, but your clarification places it outside this PR’s changes. #5758 tracks the fix to call KeyDerivation.requireNoNUL before the C-string conversion. No change is needed in this PR for that finding.

Final validation — Phase 1 + Phase 2

Static verification confirmed three non-blocking documentation, naming, and ABI-test coverage issues; no blocking correctness or layering defect was confirmed. Kotlin build/tests and the Swift frozen-schema check passed, Rust workspace tests remain pending, and the Swift SDK build was skipped; the failing PR Hygiene check is policy-only. The documented dashwallet-ios#1299 landing prerequisite remains open.

In `packages/rs-sdk-ffi/src/types.rs`:
- [SUGGESTION] packages/rs-sdk-ffi/src/types.rs:45-77: Newly owned FFINetwork has no ABI-pinning test
  The relocated enum and both conversions correctly match the pinned upstream implementation, but their compatibility contract is not covered by a Rust test. NetworkTest.kt pins Kotlin's constants, and the JNI mapping test compares named Rust variants; neither detects a change to the Rust discriminants or the Network conversions. Add a table-driven test asserting the four FFINetwork numeric values and each expected conversion in both directions. This would protect the unchanged C ABI promised by this migration without requiring a mobile build.

In `packages/swift-sdk/CLAUDE.md`:
- [SUGGESTION] packages/swift-sdk/CLAUDE.md:90-94: Anti-precedent cites a KeyDerivation.privateKey method that does not exist
  The rewritten example names `KeyDerivation.privateKey(mnemonic:path:)`, but KeyDerivation exposes no such method. Although this is an example of prohibited orchestration, using a nonexistent concrete API makes the migration guidance misleading. Reference `platform_wallet_derive_ext_priv_key_from_mnemonic`, which the rewritten tests actually use, or describe the derivation step generically while preserving the warning against orchestrating it in Swift.

In `packages/kotlin-sdk/sdk/src/test/kotlin/org/dashfoundation/dashsdk/NetworkTest.kt`:
- [NITPICK] packages/kotlin-sdk/sdk/src/test/kotlin/org/dashfoundation/dashsdk/NetworkTest.kt:11: Test name still references the old dash-network FFI home
  The adjacent source reference now correctly points to rs-sdk-ffi, but the test name still identifies dash-network as the owner of the FFI enum. Rename it to match the relocated contract.

Nothing calls `key-wallet-ffi` any more once apps use the `platform-wallet-ffi` helpers, so the workspace no longer depends on it. That unblocks bumping rust-dashcore past dashpay/rust-dashcore#776, which deletes the crate.

- `rs-unified-sdk-ffi` no longer links it, and `build_ios.sh` no longer ships its header
- the Swift `KeyWallet` classes that only wrapped it are deleted: `Wallet`, `WalletManager`, the account, address pool and transaction classes, `KeyWalletError`, `Mnemonic.toSeed` / `wordCount`, `Address.getType`, and the `KeyDerivation` path builders, `parsePath`, `createMasterKey` and extended key classes
- `Mnemonic` (`generate`, `validate`, `walletId`, `firstReceiveAddress`, the wordlist helpers), `KeyDerivation.getIdentityAuthenticationPath`, `Address.validate`, `TransactionDecoder`, `KeyManager` and the plain Swift types stay
- tests that used the deleted classes now derive through `platform_wallet_derive_ext_priv_key_from_mnemonic`, read addresses from a throwaway `PlatformWalletManager`, or check fixed wallet id and address vectors

The deleted Swift `KeyWallet` classes and methods are no longer part of `SwiftDashSDK`. Apps move to `PlatformWalletManager`, `Mnemonic.walletId(for:network:)`, `Mnemonic.firstReceiveAddress(for:network:)`, and `ManagedPlatformWallet.findBIP44AddressPath(address:)` and `bip44AddressPrivateKey(address:storage:)`.
`FFINetwork` came from rust-dashcore's `dash-network` crate behind its `ffi` feature, which dashpay/rust-dashcore#776 removes together with `key-wallet-ffi`. `rs-sdk-ffi` now defines the enum and its `Network` conversions itself, and every other FFI crate takes it from there.

The generated C definition is unchanged (`FFINetwork_Mainnet` and so on), so Swift and Kotlin need no code change. `build_ios.sh` stops shipping `dash-network.h`, and nothing enables `dash-network`'s `ffi` feature any more. Its unused `dashcore_network_get_name` export goes with it.

Looks good to me. This can be merged once dashpay/dashwallet-ios#1299 is merged and the required CI checks pass. Please keep that merge order: #1299 moves the iOS app off the KeyWallet APIs that this PR removes.

Waiting for bot review — thepastaclaw not yet. Wait for the missing reviews, or a writer can post /skip-bots to proceed without them; blocking findings still need addressing.

@thepastaclaw re your review at d001e3e3b: all three are fixed in 56e4ea2cc, folded into the commits that introduced them.

  • FFINetwork ABI: should_keep_the_ffi_network_values_and_conversions in rs-sdk-ffi/src/types.rs pins the four discriminants and both Network conversions.
  • swift-sdk/CLAUDE.md: the anti-precedent now names platform_wallet_derive_ext_priv_key_from_mnemonic instead of the nonexistent KeyDerivation.privateKey(mnemonic:path:).
  • NetworkTest.kt: renamed to ffiOrdinalsMatchSdkFfiEnum.

Re-review — Final validation — Phase 1 + Phase 2

Verified the complete diff at 56e4ea2 and found no actionable in-scope issues; all three prior findings are fixed. The relocated FFINetwork preserves its ABI values, conversions, and generated C names, and the dependency removal matches the linked upstream migration. Review was static only: exact-head Rust workspace, Swift SDK, and Kotlin SDK CI checks pass; PR Hygiene remains pending, and the documented do-not-merge-before dashpay/dashwallet-ios#1299 prerequisite remains open.
