Built for tax-grade crypto reporting

LedgerLynx combines multi-chain blockchain analysis with an AI-assisted tax engine to produce clean, auditable outputs.

AI-classified DeFi, NFTs, staking, and bridges

LedgerLynx detects complex on-chain behaviors that basic tax tools miss — without manual tagging.

Tax-grade FIFO calculations

Accurate lot tracking with capital gains/losses, cost basis, and holding period classification for every disposal.

One-click reporting and exports

Generate audit-ready summaries and shareable datasets (CSV/Excel/JSON) with privacy-first controls.

Everything you need for crypto tax compliance

From wallet sync to reporting, LedgerLynx turns raw chain data into classified, tax-relevant events with defensible calculations.

Wallet management + synchronization

Connect multiple wallets and keep transaction histories current with tier-based sync limits and background processing.

Multi-wallet support across supported chains
Background sync with transaction caps per tier
Wallet-level summaries and scan workflows

LynxMind™ transaction intelligence

Two-phase classification combines rule-based detection with AI post-processing for edge cases that require reasoning.

DEX swaps, LP deposits/withdrawals, NFTs, staking
Bridge transactions and income/airdrop detection
Shadow-mode monitoring to minimize missed taxable events

FIFO tax calculation engine

First-in-first-out lot matching calculates gains/losses, cost basis, and short/long-term holding periods across wallets.

Lot tracking by timestamp, amount, and USD basis
Automatic disposal matching with holding period rules
Fee and income event support (airdrops, staking rewards)

Multi-chain analysis

Solana-native focus with expanding support across EVM chains and beyond using a unified schema and RPC routing.

Solana primary; expanding to Ethereum, Base, Polygon, BNB, Bitcoin, HBAR
Tier-aware RPC routing, failover, and rate limiting
Extensible architecture for new L2s and chains

Audit-ready reports + exports

Generate yearly summaries, detailed transaction trails, and import-friendly exports for TurboTax and downstream systems.

PDF tax reports and wallet-level audit trails
CSV/Excel exports (Starter+) and JSON exports (Pro)
TurboTax-compatible CSV (crypto-only, no PII)

Pricing & valuation engine

USD valuation at event time with a multi-source fallback chain and caching to reduce API calls.

Price fallback chain (CoinGecko → Birdeye → Jupiter)
Historical price caching by token + date
Cost basis and proceeds in USD for reporting
