Description

Complete implementation of missing protobuf-based methods in the TypeScript/JavaScript client library.

TODO Locations

Transaction Models (packages/es/src/client/models/)

• MsgSend.toProto() - Line 24: Missing CosmosBankV1beta1MsgSend protobuf
• MsgDelegate.toProto() - Line 22: Missing CosmosStakingV1beta1MsgDelegate protobuf
• MsgUndelegate.toProto() - Line 22: Missing CosmosStakingV1beta1MsgUndelegate protobuf
• MsgBeginRedelegate.toProto() - Line 22: Missing CosmosStakingV1beta1MsgBeginRedelegate protobuf
• MsgWithdrawDelegatorRewards.toProto() - Line 22: Missing CosmosDistributionV1beta1MsgWithdrawDelegatorReward protobuf
• MsgWithdrawValidatorCommission.toProto() - Line 20: Missing CosmosDistributionV1beta1MsgWithdrawValidatorCommission protobuf

API Functions (packages/es/src/client/apis/)

• getAccount() - getAccount.ts Line 13: Missing CosmosAuthV1beta1QueryAccountService protobuf
• getNativeBalances() - getNativeBalances.ts Line 27: Missing CosmosBankV1beta1QueryAllBalancesService protobuf
• getAllNativeBalances() - getNativeBalances.ts Line 35: Missing CosmosBankV1beta1QueryAllBalancesService protobuf

Requirements

1. Generate missing protobuf definitions from Cosmos SDK
2. Import generated protobufs into TypeScript client
3. Implement toProto() methods for all transaction types
4. Implement query methods with proper types
5. Verify amino encoding compatibility

Priority

Medium - Required for complete TypeScript client functionality
