THE CHAINSCORE ADVANTAGE
Why Choose a Managed DID Registrar API
Building decentralized identity is complex. Our managed API abstracts the infrastructure, compliance, and cryptographic complexity, letting you focus on your core product and user experience.
01
Enterprise-Grade Security & Compliance
Your users' identities are paramount. We implement W3C DID standards, secure key management, and SOC 2 Type II compliant infrastructure. All cryptographic operations are performed in secure enclaves, never exposing private keys to the network.

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
We architect and deploy custom smart contracts that form the backbone of your protocol. Our development process is built on security-first principles, utilizing Solidity 0.8+, OpenZeppelin libraries, and comprehensive testing suites to ensure reliability.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with gas-optimized logic.
- Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and supply chain tracking systems.
Every contract undergoes rigorous internal audits and is prepared for third-party review, delivering production-ready code in 2-4 weeks for an MVP.
