RealBitcoinTransactionService builds and signs native SegWit transactions
client-side (mempool.space only exposes UTXOs/fee-rate/broadcast, not
construction, unlike TronGrid): greedy largest-first UTXO selection over
confirmed UTXOs, inputs*68 + outputs*31 + 11 vsize heuristic for fees
(matching pezkuwi-exchange's proven approach), RBF-signaled inputs, and a
546-sat dust threshold that folds sub-dust change into the fee rather than
creating an uneconomical output.
Each input gets its own BIP143 sighash, signed via the existing raw-hash
signing primitive (NovaSigner.signRaw with skipMessageHashing) already used
for Ethereum/Tron, then DER-encoded with low-S normalization - no new
signing call path was added, only the DER encoding step.
Also fixes multiChainEncryptionFor/getMetaAccountKeypair to recognize
Bitcoin accounts: previously neither function had any Bitcoin (or Tron)
branch, so signing would have silently used the wrong keypair. Threads a
bitcoin flag through mapMetaAccountSecretsToKeypair/DerivationPath and
AccountSecrets.keypair(chain)/derivationPath(chain) the same way ethereum
already is.
CI caught "no parameter with name 'bitcoinAddress'" in AccountMappers.kt -
every other MetaAccount subclass got these constructor params threaded
through in the Phase 2 batch, but PolkadotVaultMetaAccount only got the
isBitcoinBased guard in supportsAddingChainAccount(), not the params.
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.
* 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.
PolkadotExternalSignInteractor and ExtrinsicSplitter were using standard
CheckMortality which fails with pezsp_runtime DictEnum Era type.
Added isPezkuwiChain detection and routing to custom extensions.
ValidatorProvider, DirectStakingProperties, and DirectStakingRecommendation
were querying Asset Hub chainId for staking data (validators, exposures,
minStake, maxNominations) but these live on the relay chain. Added
chain.parentId resolution so parachain staking correctly routes to relay.
Also:
- Add VoterBagsList pallet support (Pezkuwi naming)
- Wrap BagListRepository queries in runCatching for binding compat
- Remove debug logging
