ZK-Rollup Tax Reporting | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists.

We architect and deploy audit-ready smart contracts on EVM and Solana. Our engineers specialize in Solidity 0.8+, Rust, and Anchor, implementing battle-tested patterns from OpenZeppelin and Solana Program Library.

Custom Logic: DEXs, NFT marketplaces, token vesting, DAOs, and DeFi primitives.
Security-First: Formal verification, comprehensive unit/integration testing, and pre-audit review.
Gas Optimization: Achieve up to 40% lower transaction costs through efficient code patterns and storage strategies.

We deliver a fully documented, deployable codebase in 2-4 weeks, complete with a security report and deployment scripts.

ENTERPRISE-GRADE INFRASTRUCTURE

Core Capabilities of Our Reporting Engine

Our ZK-Rollup reporting engine is purpose-built for financial institutions, delivering regulatory compliance without compromising on-chain privacy or performance.

Zero-Knowledge Proof Generation

Automated generation of zk-SNARK proofs for transaction histories, enabling users to prove tax liability without revealing underlying wallet addresses or counterparties. Built on industry-proven circuits.

Multi-Chain & Multi-Asset Aggregation

Consolidate tax events from Ethereum, Arbitrum, Polygon, and 15+ other EVM chains into a single, verifiable report. Supports ERC-20, NFTs, DeFi yields, and staking rewards.

Regulatory Schema Compliance

Pre-mapped reporting outputs for IRS Form 8949, DAC7, MiCA, and other global frameworks. Schema definitions are maintained by our legal engineering team and updated quarterly.

Real-Time Audit Trail

Immutable, timestamped record of all proof generations and report exports. Provides a defensible audit trail for regulators, powered by on-chain verification.

Enterprise-Grade API

RESTful API with OAuth2.0 authentication for seamless integration into existing accounting or compliance workflows. Includes webhooks for event-driven reporting.

SOC 2 Type II Certified Infrastructure

Your data and proofs are processed within our certified, isolated execution environments. Annual penetration testing by independent third-party auditors.

DELIVERABLES

Business Outcomes for Your Tokenization Platform

Our ZK-Rollup privacy-preserving tax reporting service delivers concrete, measurable results for your tokenized asset platform. We focus on outcomes that accelerate your time-to-market, reduce compliance risk, and build user trust.

Regulatory Compliance by Design

Automated, audit-ready tax reporting that meets IRS Form 8949, MiCA, and FATF Travel Rule requirements. We integrate compliance logic directly into your ZK-Rollup's state transition, eliminating manual reconciliation.

PROVEN FRAMEWORK

Our Methodology for Zero-Knowledge Compliance

We deliver production-ready ZK-Rollup solutions for tax reporting that balance regulatory compliance with user privacy. Our battle-tested methodology ensures auditability without exposing sensitive transaction data.

Privacy-Preserving Transaction Aggregation

We implement custom ZK circuits to aggregate user transactions into verifiable proofs. This allows tax authorities to validate total liabilities without accessing individual wallet histories, ensuring user privacy is never compromised.

Data Exposure

Audit Trail Integrity

Regulatory-Compliant Circuit Design

Our circuits are engineered to output proofs that satisfy specific jurisdictional requirements (e.g., FIFO/LIFO accounting, cost-basis reporting). We build with Plonk or Groth16, optimized for the precise logic mandated by tax codes.

FATF Travel Rule

Proof Generation

Secure On-Chain Proof Submission

We architect the full stack for generating and submitting ZK proofs to a designated compliance smart contract on L1. This creates an immutable, timestamped record of reported liabilities, backed by cryptographic certainty.

Automated Reporting & Reconciliation

Our systems automate the generation of standardized report formats (like IRS Form 8949 schemas) from the verified proof data. This eliminates manual reconciliation errors and streamlines the filing process for institutions.

Frequently Asked Questions on ZK Tax Reporting

Get clear answers on how our ZK-Rollup privacy-preserving tax reporting service works, from implementation to compliance.

A standard ZK-Rollup tax reporting system deployment takes 4-6 weeks from kickoff to production. This includes 1 week for requirements analysis, 2-3 weeks for core development and integration, 1 week for security audit and testing, and 1 week for deployment and client training. Complex integrations with legacy accounting systems may extend this by 1-2 weeks.
