Move-based Identity Verification Tools

Secure, resource-oriented smart contract libraries and CLI tools for Aptos and Sui networks. Embed verifiable credential attestation and compliance logic directly within your Move applications.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production from day one.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built for security and scale, delivering production-ready code in 2-4 weeks.

  • Full Lifecycle Development: From ideation and architecture to deployment and maintenance.
  • Security-First Approach: All code follows OpenZeppelin standards and undergoes internal audits before delivery.
  • Gas Optimization: We write efficient code to minimize transaction costs for your users.

We don't just write contracts; we build the foundational logic your entire application depends on.

Our contracts are designed for real-world use cases: DeFi protocols (ERC-4626 vaults, AMMs), NFT collections with advanced minting logic (ERC-721A), and custom utility tokens (ERC-20). We ensure they are upgradeable, composable, and secure.

  • Deliverables: Fully documented source code, deployment scripts, and a comprehensive security report.
  • Tech Stack: Solidity 0.8+, Rust (Solana), Hardhat/Foundry, and Anchor.
  • Outcome: A secure, auditable, and performant smart contract system that reduces your time-to-market and technical risk.

Frequently Asked Questions

Common questions from CTOs and technical founders about our Move-based identity tooling and development services.

For a standard identity module (e.g., soulbound tokens, credential registry), we deliver a production-ready, audited solution in 4-6 weeks. Complex systems with custom logic and multi-chain support typically take 8-12 weeks. This includes design, development, security audits, and deployment to your target network (Aptos, Sui, or custom Move VM).
