Qeychain™: Fiduciary-Native Crypto Accounting Infrastructure
Qeychain is Turnqey's crypto accounting and tax reporting engine built for Registered Investment Advisers (RIAs), CPAs, and retail users with complex transaction histories.
What Qeychain Does
Qeychain tracks cryptocurrency transactions across wallets and blockchains, calculates cost basis with 8-decimal precision, identifies wash sales per IRS Publication 550, and generates IRS-ready tax reports.
Core Capabilities
FIFO Cost Basis Engine
- 8-decimal precision across every transaction, lot, and disposal
- Handles purchases, sales, swaps, and DeFi interactions chronologically
- Supports partial sales and cross-chain scenarios
Wash Sale Detection
- Cross-chain 30-day window monitoring per IRS Publication 550
- Flags repurchases across different chains (e.g., selling ETH on Ethereum, buying on Arbitrum within 18 days)
Complete Audit Trail
Every lot records its full lifecycle: Acquired → Bridged → Swapped → Transferred → Disposed
- Full lot lineage history maintained
- Nothing silently overwritten
- Export-ready at any stage
Tax Reporting
- Form 8949 (Short-Term and Long-Term)
- Schedule 1
- Wash Sale Adjustments
- Multi-Year reporting
- PDF and CSV exports
