Compliance-First Tax Reporting API

A robust API service that allows fintechs and crypto platforms to integrate automated, regulation-first tax calculation and reporting into their existing user-facing products.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that form the backbone of your dApp. Our team specializes in Solidity 0.8+, Rust (Solana), and Vyper, implementing battle-tested patterns from OpenZeppelin and Sealevel. Every contract is built with security-first principles, including comprehensive unit/integration testing and formal verification where required.

From tokenomics to complex DeFi logic, we translate your business requirements into immutable, gas-efficient code.

  • Full Development Lifecycle: Design, audit, deployment, and maintenance.
  • Token Standards: ERC-20, ERC-721, ERC-1155, SPL, and custom implementations.
  • Security Audits: Optional integration with top firms like CertiK or Trail of Bits.
  • Deliverables: Verified source code, deployment scripts, and technical documentation.
