As salam alaikum! My name is Muhammad Ali, an expert in Bookkeeping, Data Analysis, and most importantly, adept at handling large volumes of data - making me an ideal fit for your project. Over the years, I've honed my skills in Excel, Python, and other relevant tools which will be crucial in turning your CSV files into fully reconciled reports. In approaching the reconciliation process, I place a premium on accuracy and transparency. I'll first undertake thorough imports of all data sources to ensure no gaps or duplicates exist. Next, I'll develop a rigorous matching logic that integrates your on-chain wallet activities with the corresponding exchange statements for each calendar year. But I enhance this approach by constantly checking for errors and implementing appropriate error handling techniques at every stage to maintain the verifiability and accuracy of the final results. Additionally, I'm comfortable working with different specialist tools such as CoinTracking, Koinly, and CoinLedger - giving you flexibility in deciding which platform best suits your needs. Finally, in guaranteeing a comprehensive end-of-year report ready for your tax preparer, I'll calculate both realized and unrealized gains/losses, track cost-basis diligently and present complete P&L statement for each period

Hi, I have complete CSV exports from every centralized exchange I’ve used, along with full on-chain wallet address histories, covering the 2022, 2023, 2024, and 2025 calendar years. For transparency, you are also welcome to pull the same data directly via the exchanges’ APIs; however, the raw CSV files will serve as the single source of truth. The objective is to convert this data into fully reconciled, tax-ready reports. This includes a year-by-year ledger that reconciles on-chain wallet activity with corresponding centralized exchange transactions, realized and unrealized gains and losses with accurate cost-basis tracking, end-of-year holdings, and a concise profit-and-loss statement for each year. I also need a final annual summary for each period that can be handed directly to a tax preparer without further cleanup or adjustments. I am comfortable using whichever specialist tools you recommend, such as CoinTracking, Koinly, CoinLedger, or similar platforms, provided the outputs are accurate, auditable, and verifiable. Before proceeding, please briefly outline your approach to data imports and normalization, wallet-to-exchange matching and reconciliation logic, and how you handle errors, missing data, and discrepancies. Accuracy is paramount. Proven experience handling high-volume crypto data across multiple wallets and centralized exchanges is essential. If this aligns with your expertise, I look forward to working together. Best regards, Mussadiq Hussain

Hello, I understand you have full CSV exports and wallet histories from 2022 to 2025 and want them turned into clear, reconciled reports that match wallet activity and exchange data perfectly. My approach will be to first import all your CSV files and use API data only for cross-checking, focusing on accuracy. I'll set up matching of transactions between wallets and exchanges using unique identifiers and timestamp checks. If errors or mismatches appear, I'll flag and resolve them step-by-step. Afterwards, I will calculate gains and losses, track cost basis, summarize your holdings, and create a neat P&L statement for each year, making sure these reports are ready for your tax preparer. Before I start, I'll need detailed info on any asset types involved, preferred tools or formats, and any special cases or transactions you want highlighted. Are there any specific assets or transaction types that need special attention or treatment during reconciliation? Thanks,

Hi there, i have significant experience reconciling crypto transactions across exchanges and wallets. *My process focuses on carefully matching your on-chain wallet history with exchange statements to create a single, unified ledger, which is the foundation for all gain/loss calculations. To begin, I'll import all your CSV files and wallet addresses. The key is setting precise matching rules to link deposits and withdrawals, followed by a manual review to catch any discrepancies. For a complete and accurate report, I'll just need confirmation that your CSV files include all trade, transfer, and reward history, and a list of any non-custodial wallets used during those years.

@juanjosec63

Hello, I’m excited about the opportunity to reconcile your multi-year crypto activity into clear, accurate, tax-ready reports. With hands-on experience handling high-volume CEX CSVs, on-chain wallet data, and gain/loss calculations across multiple years, I can produce balanced ledgers, precise cost-basis tracking, and clean P&L summaries you can hand directly to a tax preparer. I’ll use your CSV exports as the source of truth, cross-verify with APIs where helpful, and apply careful matching and validation to resolve discrepancies and ensure accuracy. You can expect a transparent process, verifiable results, and well-documented outputs for each year from 2022 through 2025. Best regards, Juan

@yuliussmayoru

Hi. Crypto reports usually go sideways when CSVs don’t quite line up with on-chain history or when transfers get mistaken for trades, that’s the problem I focus on fixing. I’ve reconciled high-volume CEX + wallet data before, and the key is treating one source as truth while making every match traceable. Your setup actually makes this cleaner than most. I’d start by normalizing all CSVs into a single schema, then import wallet histories and align deposits/withdrawals against exchange records using tx hashes, timestamps, and amounts (with tolerance rules for fees and confirmations). Transfers get flagged so they don’t inflate P&L. From there, I’ll compute cost basis, realised vs unrealised gains, and end-of-year holdings per asset, per year. Tools like Koinly or CoinTracking are fine as a check, but I’m comfortable validating and correcting edge cases outside the tool when needed. For each year (2022–2025), you’ll get a clean ledger that balances, a clear P&L, and a tax-ready summary your preparer can actually trust. Before starting, I’ll just need exchange names, wallet types, preferred cost-basis method, and confirmation of any internal transfers or lost funds. Accuracy first, no black boxes, and everything verifiable.

@sasaprogramer21

Hi, I can turn your 2022 to 2025 CEX CSV exports plus wallet histories into reconciled, audit friendly annual reports that a tax preparer can use with confidence. My approach is reconciliation first, then tax math: - Data ingestion and normalization Parse each exchange CSV into a unified trade, transfer, fee, reward schema, preserving raw IDs, timestamps, and symbols. Import on chain activity per wallet address, normalize token contracts, and map networks. - Matching and balancing Build a matching layer that links CEX withdrawals and deposits to on chain transfers using amount, timestamp windows, tx hash when available, and address pairs. Flag unmatched items, internal transfers, and fee only movements. Produce a year by year ledger that balances: opening holdings + inflows − outflows + PnL = closing holdings. - Cost basis and PnL Compute realized gains using your chosen method (FIFO, HIFO, or specific identification if supported by evidence), track lots, fees, and gas. - Verification and error handling Exception reports for missing prices, duplicates, symbol migrations, chain reorg anomalies, and time zone drift. Every number traceable back to a source row or tx. What I need from you before starting Preferred tax method (FIFO or other) and jurisdiction rules, base currency, time zone preference, list of exchanges, all wallet addresses and networks used, whether staking rewards are treated as income, and any special events (airdrops, forks, hacks, lost keys). Best Alex
