CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
Deploy with confidence using battle-tested patterns and formal verification.
Our engineers specialize in:
- Solidity 0.8+ development for EVM chains (Ethereum, Polygon, Arbitrum, Base).
- Rust for Solana and other high-performance ecosystems.
- Upgradeable proxy patterns using OpenZeppelin and established security frameworks.
- Integration with oracles, bridges, and decentralized storage.
We deliver more than code. You get a full audit package with unit tests, integration tests, and documentation, ensuring a smooth path to mainnet launch and ongoing protocol maintenance.

Core Capabilities of Our Tax Pallet
Our Substrate-based tax reporting pallet delivers production-ready compliance, designed for FinTechs and crypto-native businesses. We provide the technical foundation for automated, accurate, and auditable tax calculations directly on-chain.
01
Real-Time Transaction Classification
Automatically tags every on-chain transaction (transfers, swaps, staking rewards, NFT mints) with the correct tax treatment (income, capital gain, cost basis) using configurable rule sets. Eliminates manual data reconciliation for your users.

Event Types Supported
< 100ms

02
Multi-Jurisdiction Rule Engine
Pre-configured logic for key regulatory regimes (e.g., FIFO, LIFO, HIFO, ACB) with the ability to add custom rules via governance. Ensures your application remains compliant as users and regulations evolve.

03
Privacy-Preserving Calculation
Compute tax liabilities and generate reports using zero-knowledge proofs or trusted execution environments (TEEs). Users can prove tax obligations without exposing their entire transaction history to your application.

Frequently Asked Questions
Get clear answers on our process, timeline, and technical approach for building custom tax reporting modules on Substrate.
For a standard tax reporting pallet with core features (transaction categorization, calculation, and reporting endpoints), development and audit typically take 4-6 weeks. Complex integrations with existing enterprise systems or multi-chain data ingestion can extend this to 8-10 weeks. We provide a detailed project plan with milestones during the initial consultation.
