Complete History
Every trade, deposit, withdrawal, and fee from every venue and wallet.
We build custom portfolio reconciliation and tax-data automation for active crypto traders, funds, and OTC desks - aggregating trades across exchanges, wallets, and DeFi into accurate P&L, holdings, and accountant-ready reports.
Agreed scope · Reviewable milestones · Documented handover

Multi-exchange aggregation
Transfer matching
Cost-basis engine
Accountant-ready exports
Retail tax tools break exactly when you need them: high trade counts, many venues, DeFi positions, internal transfers, and edge cases they were never built for. We build custom pipelines instead - pulling complete trade history from every exchange API and wallet, matching transfers so they are not double-counted, computing cost basis by your method, and producing clean P&L, holdings, and export files your accountant can actually use. Built for volumes and complexity where off-the-shelf tools give up. We produce accurate data - your tax adviser applies your jurisdiction’s rules.
