The Tax Layer of Web3.
TaxChain is an automated, blockchain-native protocol that simplifies crypto taxation across jurisdictions. It tracks user transactions in real time, classifies them by type (e.g., trades, airdrops, staking, liquidity provision, mining), and maps each activity to the relevant local tax treatment.
Trusted by key players in the industry.
Monthly Reporting
Making blockchain ready for mainstream and authorities
Through its monthly reporting system, TaxChain delivers clear, audit-ready summaries to individual users. By leveraging NFT-based access permissions, it also enables tax advisors to securely view client data and offer tailored support — without compromising privacy or ownership of data.
Strategic Framework
Automated, trustless, and jurisdiction-aware crypto tax reporting
We envision a future where blockchain activity and tax obligations are natively connected, eliminating the need for manual tracking, guesswork, and regulatory fear. In this future, tax compliance is no longer a burden, but a background process — secure, real-time, and fully tailored to local laws.
Tax Optimization
AI powered tax optimization tools for holders
We offer a wide range of optimization tools. Our TaxChain AI agents are capable of finding the best strategies to optimize your transactions to lower your tax obligations.
Intelligent Classification Engine (ICE)
Every transaction hash is passed through a multi-layer heuristic model that determines the economic intent of the action.
Custom adapters decode popular smart-contract ABIs (Uniswap V3, Aave, Lido, Curve, OpenSea, Blur, MakerDAO, …) so even complex, multi-step calls are understood in context.
Jurisdictional Rulebook Layer (JRL)
Country-specific logic packs
Each supported jurisdiction (DE, AT, CH, FR in v1) is modeled as a standalone ruleset that codifies holding-period tests, income vs. capital classifications, cost-basis methods (FIFO, LIFO, average), tax-free thresholds, and special regimes (e.g., German 1-year speculation period, Swiss wealth tax).
Monthly & On-Demand Reporting Suite
Regulator-ready exports
Files are formatted to match local tax-form schemas (e.g., Anlage SO for Germany, Formulaire 2086 for France) so users can copy-paste or import directly into national e-filing portals.
NFT-Gated Professional Access
Permission NFTs (pNFTs)
A user can mint a non-transferable ERC-721 token that embeds read-only decryption rights to their reports. Assigning the pNFT to a wallet controlled by a tax advisor instantly grants secure portal access.
State of the art architecture
TaxChain is architected as a layer-zero compliance fabric that spans on-chain smart-contract components, off-chain verifiable compute, and a cryptographically linked data-availability layer. The guiding design principles are:

Frequently asked questions
What chains does TaxChains tools support?
TaxChain supports a wide variety of different wallet provides and exchanges. Our own developed architecture allows us to adapt fast to new developments in the industry.
How does TaxChain work?
To guarantee accuracy, completeness, and verifiability, the protocol employs a multi-layer architecture that ingests raw on-chain activity from dozens of networks, enriches it with contextual metadata, and writes the result into an append-only Tax Graph keyed to each user. Below is a deep technical walk-through of that pipeline.
How much does TaxChain cost?
Taccess (short for Tokenized Access) is a novel utility model within the TaxChain ecosystem that provides tiered, non-expiring access to TaxChain tools and services based on the user’s $TAX holdings and staked amounts. It ensures that long-term token holders receive tangible, recurring utility—not just speculative value—by unlocking premium protocol features without requiring repeated payments.
Taccess transforms $TAX from a simple payment token into a perpetual access key, making it the first crypto-native model for decentralized SaaS-style infrastructure in the tax compliance sector.
What is the classification engine?
Once raw blockchain activity has been ingested and written into each user’s Tax Graph, the next challenge is to translate that low-level data into events that accountants and tax authorities actually recognise. The Classification Engine (CE) is the subsystem that performs this translation. It assigns every Atomic Tax Unit (ATU)a precise economic meaning—trade, staking reward, LP deposit, DAO distribution, NFT sale, and so on—together with a machine-readable confidence score.
