I have complete CSV exports from every centralized exchange I used, along with wallet address histories, covering the calendar years 2022, 2023, 2024 and 2025. For transparency you can also pull the same data through the exchanges’ APIs, but I rely on the raw CSV files as the single source of truth. Your task is to turn those files into fully reconciled reports: • A year-by-year ledger that balances on-chain wallet activity with the matching exchange statements • Realised and unrealised gains/loss calculations, cost-basis tracking, end-of-year holdings and a concise P&L for each period • A final summary for each year that could be handed straight to a tax preparer. I am comfortable with whichever specialist tools you prefer—CoinTracking, Koinly, CoinLedger etc —so long as the end result is accurate and verifiable. Please outline briefly how you would approach the reconciliation (imports, matching logic, error handling) and any additional information you will need from me before you start. Accuracy is paramount; experience handling high-volume crypto data across wallets and CEX accounts is essential. If that sounds like your wheelhouse, I look forward to working together.

I specialize in high-volume crypto accounting and full reconciliation across CEXs and on-chain wallets, with tax-ready outputs. My approach is to import all CSVs as the source of truth, cross-verify via exchange APIs, normalize transactions, and reconcile deposits/withdrawals against wallet activity using deterministic matching (TXIDs, timestamps, amounts, fees). I then calculate realized/unrealized P&L, cost basis (FIFO/LIFO/HIFO as required), end-of-year holdings, and produce clean annual summaries suitable for a tax preparer. I use tools like CoinTracking, Koinly, or CoinLedger where helpful, combined with manual audits and exception handling to resolve mismatches, missing cost basis, or internal transfers. Before starting, I’d need exchange lists, wallet addresses, preferred cost-basis method, tax jurisdiction, and confirmation of any non-standard activity (OTC, DeFi bridges, staking, airdrops). Accuracy and verifiability are my top priorities.
