Add TokenType enum and GreenPointsToken config in Models.kt - Implement ERC-20 balance fetching and transfer encoding in TssRepository - Update TransactionUtils with ERC-20 transfer support - Add dual balance display (KAVA + 绿积分) in WalletsScreen - Add token type selector in TransferScreen Electron changes: - Add TokenType and GREEN_POINTS_TOKEN config in transaction.ts - Implement fetchGreenPointsBalance and ERC-20 transfer encoding - Update Home.tsx with dual balance display and token selector - Add token selector styles in Home.module.css Token contract: 0xA9F3A35dBa8699c8C681D8db03F0c1A8CEB9D7c3 (Kava mainnet) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../java/com/durian/tssparty/MainActivity.kt | 8 +- .../tssparty/data/repository/TssRepository.kt | 92 ++++++- .../durian/tssparty/domain/model/Models.kt | 35 +++ .../presentation/screens/HomeScreen.kt | 49 +++- .../presentation/screens/TransferScreen.kt | 160 ++++++++++-- .../presentation/screens/WalletsScreen.kt | 77 ++++-- .../presentation/viewmodel/MainViewModel.kt | 36 ++- .../durian/tssparty/util/TransactionUtils.kt | 93 ++++++- .../contracts/CONTRACT_INFO.md | 115 +++++++++ .../contracts/DurianUSDT.abi | 229 ++++++++++++++++++ .../contracts/DurianUSDT.bin | 1 + .../contracts/DurianUSDT.sol | 78 ++++++ .../contracts/KAVA_NETWORK.md | 120 +++++++++ .../contracts/WALLET_KEYS.md | 83 +++++++ .../src/pages/Home.module.css | 46 +++- .../service-party-app/src/pages/Home.tsx | 164 +++++++++---- .../src/utils/transaction.ts | 166 +++++++++++-- 17 files changed, 1415 insertions(+), 137 deletions(-) create mode 100644 backend/mpc-system/services/service-party-android/contracts/CONTRACT_INFO.md create mode 100644 backend/mpc-system/services/service-party-android/contracts/DurianUSDT.abi create mode 100644 backend/mpc-system/services/service-party-android/contracts/DurianUSDT.bin create mode 100644 backend/mpc-system/services/service-party-android/contracts/DurianUSDT.sol create mode 100644 backend/mpc-system/services/service-party-android/contracts/KAVA_NETWORK.md create mode 100644 backend/mpc-system/services/service-party-android/contracts/WALLET_KEYS.md diff --git a/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/MainActivity.kt b/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/MainActivity.kt index 13855bc0..8d093ef1 100644 --- a/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/MainActivity.kt +++ b/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/MainActivity.kt @@ -17,6 +17,7 @@ import androidx.navigation.compose.composable import androidx.navigation.compose.currentBackStackEntryAsState import androidx.navigation.compose.rememberNavController import com.durian.tssparty.domain.model.AppReadyState +import com.durian.tssparty.domain.model.TokenType import com.durian.tssparty.presentation.components.BottomNavItem import com.durian.tssparty.presentation.components.TssBottomNavigation import com.durian.tssparty.presentation.screens.* @@ -63,6 +64,7 @@ fun TssPartyApp( val settings by viewModel.settings.collectAsState() val createdInviteCode by viewModel.createdInviteCode.collectAsState() val balances by viewModel.balances.collectAsState() + val walletBalances by viewModel.walletBalances.collectAsState() val currentSessionId by viewModel.currentSessionId.collectAsState() val sessionParticipants by viewModel.sessionParticipants.collectAsState() val currentRound by viewModel.currentRound.collectAsState() @@ -167,6 +169,7 @@ fun TssPartyApp( shares = shares, isConnected = uiState.isConnected, balances = balances, + walletBalances = walletBalances, networkType = settings.networkType, onDeleteShare = { viewModel.deleteShare(it) }, onRefreshBalance = { address -> viewModel.fetchBalance(address) }, @@ -189,6 +192,7 @@ fun TssPartyApp( TransferScreen( wallet = wallet, balance = balances[wallet.address], + walletBalance = walletBalances[wallet.address], sessionStatus = sessionStatus, participants = signParticipants, currentRound = signCurrentRound, @@ -202,8 +206,8 @@ fun TssPartyApp( error = uiState.error, networkType = settings.networkType, rpcUrl = settings.kavaRpcUrl, -
