[ECO Bounty] ioTexScan Missing "IN" (Incoming) Transactions in Address History

Platform: IoTeXScan
URL: https://iotexscan.io/address/0x5d9d12c6d996cce9b6b4aadd8d3d4f81b0465e8d
Severity: High (Critical for wallet balance verification & tax reporting)
Date: March 8, 2026
Reporter: User Wallet Address 0x5d9d12c6d996cce9b6b4aadd8d3d4f81b0465e8d

Issue Summary:
The transaction history page for address 0x5d9d...5e8d only displays OUT (outgoing) transactions. All IN (incoming) transactions are missing from the list, despite the address having received transfers (as evidenced by non-zero balance or expected receipts). This creates a false impression that the wallet only sends funds and never receives them.

Steps to Reproduce:

1. Navigate to https://iotexscan.io/address/0x5d9d12c6d996cce9b6b4aadd8d3d4f81b0465e8d

2. Scroll to "Transactions" tab/section

3. Observe the transaction list

4. Issue: Only "OUT" transactions appear (send operations)

5. Missing: All "IN" transactions (receive operations) are absent

6. Cross-check: Verify on alternative explorer (e.g., https://iotexscout.io/) or check wallet balance to confirm incoming txs exist

Expected Behavior:
The transaction history should display a complete chronological list including:

• IN transactions: Incoming transfers, token receipts, staking rewards, airdrops

• OUT transactions: Sends, contract interactions, staking actions

• SELF transactions: Self-transfers, contract deployments

• Filter options: Toggle between All / IN / OUT / Token Transfers / NFTs

Actual Behavior:

• Only OUT transactions are indexed and displayed

• IN transactions are completely missing from the UI

• No filter option to view incoming history

• Users cannot verify receipt of funds via explorer
