```

## Expected Workflow

1. **Transaction Details** → `getTransactionById("bd32eef7...")` → Raw data, contract type
2. **Transaction Receipt** → `getTransactionInfoById("bd32eef7...")` → Result, logs, fees
3. **Confirmation** → `solidityGetTransactionById("bd32eef7...")` → Check finality
4. **Contract ABI** → `getContract(contractAddress)` → ABI for decoding method + events
5. **Internal Txs** → `getInternalTransactionsByTxId("bd32eef7...")` → Internal transfers
6. **Events** → `getEventsByTransactionId("bd32eef7...")` → Decoded events
