Same read/send-capable chain-family pattern as Tron/Bitcoin, but for
Ed25519/SLIP-0010 instead of secp256k1/BIP32 (Solana's account id IS its
raw public key, so no separate address-hash derivation step is needed).
- SLIP-0010 Ed25519 keypair derivation (Bip32Ed25519KeypairFactory),
cross-validated against an independent slip10 reference implementation
and pinned to a known-good test vector.
- Chain.isSolanaBased / Chain.Asset.Type.SolanaNative wired through every
chain-mapper, account-model, and signer dispatch site (mirrors the
existing Tron/Bitcoin wiring exactly).
- SolanaAddressBackfillMigration derives Solana keys for wallets created
before this support existed, same self-healing no-stuck-flag design as
the Tron/Bitcoin backfills - also fixed a latent bug in those two
migrations where MetaAccountSecrets/MetaAccountLocal.addXAccount()
dropped sibling chain-family fields on a re-run.
- Room migration 75->76 adds isSolanaBased/solanaPublicKey/solanaAddress
columns.
- CloudBackup's already-reserved solanaAddress/SolanaSecrets fields are
now actually read/written by RealLocalAccountsCloudBackupFacade; also
fixed isCompletelyEmpty() to check solana, so a Solana-only wallet
doesn't get silently dropped from backup.
Bitcoin was branched off main independently instead of continuing on top
of the Tron send branch, which caused real divergence: both branches touch
the same shared signing/DI code (multiChainEncryptionFor, getMetaAccountKeypair,
NodeHealthStateTesterFactory, AssetsModule/TypeBasedAssetSourceRegistry,
CloudBackup schema, Fee model), and both need to ship together in one
coordinated release once wallet-util's master is unblocked. Merging now
reconciles that before it gets any harder, and gives one branch/versionCode
history for device testing instead of two that silently diverge.
Conflict resolutions of note:
- SecretStoreV2/SecretsSigner: getKeypair and multiChainEncryptionFor now
recognize Tron AND Bitcoin accounts (isTronBased/isBitcoinBased both
threaded through, checked before the Ethereum fallback).
- AccountDataSourceImpl: both address-backfill migrations now run
sequentially in one coroutine (Tron's fix for a race against the legacy
migration applies equally to Bitcoin's backfill).
- CloudBackup: kept Tron's forward-looking Solana schema reservation
alongside Tron's and Bitcoin's now-real fields.
- ChainRegistryModule/NodeHealthStateTesterFactory: adopted Tron's
self-contained short-lived OkHttpClient (simpler than threading the
shared app-wide client through RuntimeDependencies, which is reverted).
- RealSecretsMetaAccount: extended Tron's chain-account MultiChainEncryption
fix to also cover Bitcoin, for the same underlying reason.
- ChainExt.isValidAddress: Tron's branch independently closed the
pre-existing Tron validation gap; kept alongside Bitcoin's own check.
Derives a BIP84 (native SegWit) keypair alongside the existing substrate/
ethereum/tron ones, stores it in MetaAccountSecrets/CloudBackup, persists
bitcoinPublicKey/bitcoinAddress on meta_accounts (DB migration 74->75), and
threads isBitcoinBased through Chain/ChainLocal/mappers/ChainExt/ChainRegistry
the same way isTronBased was wired. Adds BitcoinAddressBackfillMigration,
mirroring TronAddressBackfillMigration, so existing wallets get a Bitcoin
address without re-import.
Found via manual device testing against a real, pre-Tron production
wallet: TRX/USDT-TRC20 didn't appear anywhere in the Assets list, not
even as a zero balance - unlike every other configured chain (KSM, USDC,
ETH, BNB, AVAX, LINK all show up at 0). Root cause: MetaAccount.hasAccountIn()
gates Tron balance sync on tronAddress != null, but tronAddress is only
ever populated once, at fresh-mnemonic-creation time in
AccountSecretsFactory.metaAccountSecrets(). The migration that added the
tronPublicKey/tronAddress columns (73_74_AddTronSupport) is pure ALTER
TABLE like every other migration in this codebase - it never derived a
value for pre-existing rows. Net effect: BalancesUpdateSystem silently
skips Tron entirely for every wallet that existed before this feature
shipped, with zero error surfaced anywhere. No automated test catches
this because every automated test creates a fresh (post-Tron) account -
this is exactly the class of bug that only manual testing against a real,
aged wallet can find.
Adds TronAddressBackfillMigration: a one-time, flag-gated pass (mirroring
the existing AccountDataMigration idiom) over SECRETS-type accounts that
still hold their mnemonic entropy in SecretStoreV2 but have no TronKeypair
yet. Derives the Tron keypair via AccountSecretsFactory.chainAccountSecrets
(isEthereum=true, same BIP32/secp256k1 path Tron already uses everywhere
else) at TRON_DEFAULT_DERIVATION_PATH - the same call fresh-account
creation already makes - so a backfilled wallet ends up with byte-for-byte
the same Tron address it would have gotten had it been created today, not
a separately-reimplemented derivation. Watch-only/Ledger/Json/multisig/
proxied accounts (never had a Tron-capable mnemonic) and raw-seed imports
(no entropy) are correctly left untouched, same as they already are for
Ethereum.
Includes a dedicated unit test asserting the backfill derives the exact
same reference Tron address (TUEZSdKsoDHQMeZwihtdoBiN46zxhGWYdH) that
TronDerivationTest already cross-validated against live TronGrid data for
the standard BIP39 test mnemonic - this touches real wallets' key
material, so it's pinned to a known-good vector rather than just asserting
against its own output.
SELECT * FROM chains had no ORDER BY - SQLite gives no ordering guarantee
for that, so registration/connection order across ~98 chains was
effectively unpredictable per run. The merged chains.json lists Pezkuwi's
own chains first (wallet-utils' merge_chains()), and CollectionDiffer's
findDiff()/Room's batch insert both preserve that order on first sync, so
ordering by rowid (insertion order) makes Pezkuwi's own chains reliably
register and start connecting first/early, instead of being interleaved
unpredictably among ~90+ Nova-inherited chains where they could end up
processed dead last - observed directly: a fresh install took 45+ seconds
without a single Pezkuwi-related registration/connection attempt.
No user should wait minutes for their own wallet's native chain to even
start syncing after install, regardless of whether the eventual outcome
is correct.
* Add read-only Tron (TRC20) chain family support
Adds Tron as a third chain family alongside Substrate and EVM:
address derivation (BIP44 coin type 195, secp256k1 reused from the
existing Ethereum path, Base58Check encoding), TronGrid-backed TRX
and TRC20 USDT balance display, and a Room migration for the new
per-account Tron key/address columns. Read-only only — no send,
signing, or broadcast support yet.
* fix: exhaustive when branches for Trc20/TronNative asset types
ChainExt.kt's onChainAssetId and Common.kt's existentialDepositError
both switch exhaustively over Chain.Asset.Type and didn't have cases
for the new Trc20/TronNative variants, breaking compilation. Trc20
mirrors EvmErc20 (contract address as the on-chain id, dust burns
rather than transfers on removal); TronNative mirrors EvmNative.
