Avatar System Upgrade & Migration

Professional services for safely upgrading live avatar system smart contracts, migrating user data, and managing backward compatibility.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your token, DeFi, or NFT project.

We architect and deploy custom smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process ensures security-first code, gas optimization, and full audit readiness.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance logic.
  • DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing platforms.
  • Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and custom on-chain business rules.

We deliver battle-tested contracts with a 99.9% uptime SLA and comprehensive documentation, reducing your time-to-market from months to as little as 2 weeks for an MVP.

Our engineers follow OpenZeppelin standards and implement formal verification where required. Every contract undergoes internal security review and is structured for seamless integration with frontends and indexers.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built on a foundation of battle-tested security and gas optimization.

We architect and deploy custom smart contracts that power your core business logic, from tokenomics to complex DeFi protocols. Every line of code is written with security-first principles, utilizing OpenZeppelin libraries and following Solidity best practices to mitigate vulnerabilities before the first audit.

  • From Concept to Mainnet: We handle the full lifecycle—design, development, testing, and deployment—ensuring your contracts are audit-ready and production-deployed in as little as 2-4 weeks.
  • Gas Optimization: Our contracts are engineered for cost-efficiency, reducing user transaction fees by up to 40% through optimized storage and logic patterns.
  • Comprehensive Testing: We deliver contracts with >95% test coverage using Hardhat or Foundry, including simulations of mainnet conditions and edge cases.

We don't just write code; we build the secure, reliable foundation your Web3 application depends on. Our contracts are designed for long-term maintainability and seamless integration with your front-end and backend systems.
