Stop guessing from raw Transfer logs. Decode directly from protocol semantic anchors, isolate LP fees from principal withdrawals, and replay historical FMV prices for verifiable audit trails.
Enter an Ethereum Mainnet tx hash to call POST /v1/classify and get structured tax events
Purpose-Built Tax Classification for DeFi
More than decoding logs — mapping on-chain activities directly into capital gains and income reporting entities.
Eliminate guesswork from raw ERC20 Transfers. Directly decode core Uniswap V3 events (Swap, Mint, Burn, Collect) for ground truth.
Novel correlation between Burn and Collect events. Isolate LP fee earnings and prevent capital return from being falsely reported as taxable income.
Accurately replay historical CoinGecko pricing based on exact block timestamp to evaluate notional USD amounts and fee income.
Every classified event includes exact log indices, pool contract addresses, and pricing timestamps to withstand stringent tax scrutiny.
Highly extensible src/decoders/ architecture designed to plug in major DeFi protocols effortlessly
Ready-to-use REST API
Seamlessly embed into your personal portfolio, tax SaaS, or enterprise accounting stack.
