Institutional Cross-Chain Screening Gateway

A managed, high-availability API gateway that aggregates and normalizes global sanctions lists, providing a single point of screening for institutions operating across multiple blockchains.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists for FinTech and enterprise applications.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness.

  • Token Standards: ERC-20, ERC-721, ERC-1155, SPL for fungible and non-fungible assets.
  • DeFi Protocols: Custom DEXs, lending/borrowing pools, staking mechanisms, and yield strategies.
  • Enterprise Logic: Multi-signature wallets, DAO governance, vesting schedules, and access control systems.
  • Security: Built with OpenZeppelin libraries and hardened against common vulnerabilities.

Deliver a fully audited, mainnet-ready contract suite in as little as 4 weeks, backed by a 99.9% uptime SLA for deployed protocols.
