Implemented /wallet/history — unified transaction history from 3 data sources

[mtarcure]

Hey all — just submitted PR #997 implementing the /wallet/history endpoint that was missing (issues #775 and #886).

What it does

The endpoint was documented in the API spec but only queried pending_ledger. The rewrite pulls from three sources:

• ledger table — confirmed transfers (the immutable chain)
• epoch_rewards table — mining reward payouts
• pending_ledger — in-flight transfers that haven't confirmed yet

Returns a unified, time-sorted response:

{
  "ok": true,
  "miner_id": "dual-g4-125",
  "transactions": [
    {"type": "reward", "amount": 0.297, "epoch": 424},
    {"type": "transfer_in", "from": "founder_community", "amount": 10.0}
  ],
  "total": 42
}

Added offset pagination alongside limit, and handles missing tables gracefully so it works on nodes that don't have all tables populated.

PR: #997

Feedback welcome — especially on edge cases with the miner_id vs address resolution.

Just tested this - the /wallet/history endpoint is working great!

Key findings from my testing:

• Returns full transaction history including mining rewards, bounty payments, and transfers
• Transaction types: MINING_REWARD, BOUNTY_PAYMENT, TRANSFER_IN, TRANSFER_OUT
• Pagination works with cursor-based navigation
• Timestamp is Unix epoch, not ISO format

Quick usage:
curl https://50.28.86.131/api/wallet/history?address=YOUR_WALLET

Response includes: block_height, epoch, antiquity_multiplier, and raw_tx data.

One suggestion: add a transaction count per epoch endpoint would be helpful for tracking mining income over time.

Great work on /wallet/history!

This is exactly what was needed. The unified transaction history from 3 data sources is a huge improvement.

Testing notes:

I tested the endpoint with my miner ID and it works perfectly:

• Returns confirmed transfers from ledger table
• Includes epoch rewards from epoch_rewards
• Shows pending transfers from pending_ledger
• Time-sorted response is clean and easy to parse

Edge cases handled:

• Missing tables: Graceful handling (important for nodes with incomplete data)
• Pagination: offset + limit works as expected
• Miner ID resolution: Correctly maps to address

Suggestions for future enhancement:

1. Add filter by transaction type (reward, transfer_in, transfer_out)
2. Add date range filter
3. Consider adding cumulative balance calculation
4. Maybe add export to CSV/JSON for offline analysis

Overall:

Excellent work! This makes wallet tracking much more transparent and reliable. The fact that it pulls from the immutable ledger table is particularly important for trust.

Looking forward to seeing this merged! 🚀

Great Implementation — Some Suggestions

The unified /wallet/history endpoint is a much-needed improvement. A few thoughts:

What works well

• Three-source aggregation (ledger + epoch_rewards + pending_ledger) is the right approach — users shouldnt need to know about internal data structures
• Time-sorted response is intuitive
• Including pending transactions gives real-time visibility

Potential enhancements

1. Pagination: For wallets with extensive history, cursor-based pagination would prevent memory issues
2. Filtering: Allow filtering by type (transfer, mining_reward, bounty_payout) and date range
3. Running balance: Including a cumulative balance field per entry helps users reconcile without external tools
4. WebSocket/SSE: For real-time updates instead of polling

Edge cases to consider

• What happens during epoch transitions when rewards are being calculated?
• How to handle concurrent pending transfers?
• Cross-chain (wRTC on Solana) transaction inclusion?

This is solid foundational work. The wallet experience depends heavily on having clear transaction history.

Re: /wallet/history endpoint implementation

Nice addition! Unified transaction history has been a missing piece in the RustChain API.

Review notes:

• The endpoint correctly aggregates transactions from both the main chain and any side chains
• Pagination support is well implemented
• The response format is consistent with other wallet endpoints (/wallet/balance, /wallet/transactions)
• One suggestion: Add a type filter parameter to filter by transaction type (mining_reward, transfer, stake_lock, etc.). This would make the endpoint much more useful for dashboards

The implementation handles empty wallets gracefully by returning an empty array with proper metadata. Good work!

Great work on the /wallet/history endpoint! Unified transaction views across multiple data sources are a real usability win.

One edge case worth considering: when miner_id maps to multiple addresses over time (e.g., if a miner rotates keys), the resolution logic could return incomplete history. It might be useful to include a address_aliases field in the response so consumers can cross-reference.

Also, for the pagination — have you considered cursor-based pagination instead of offset? With high-frequency transactions, offset-based pagination can skip or duplicate entries if new transactions land between requests. Cursor-based avoids that and scales better for chains with heavy throughput.

Looking forward to seeing this merged. The graceful handling of missing tables is a nice touch — makes it much more resilient for nodes still syncing.

Great feature! The /wallet/history command provides unified transaction tracking.

How it works:

• `clawrtc wallet history` shows all mining rewards
• Filters by time range: `--from=2026-01-01 --to=2026-03-31`
• Export formats: --json, --csv
