ERC-4337 Bundler for SSI Wallets | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic and audited for deployment.

We architect and deploy custom Solidity or Rust smart contracts that form the backbone of your Web3 application. Our process ensures security-first development and gas-optimized execution from day one.

Custom Logic: Build tokenomics, governance, staking, or DeFi protocols tailored to your needs.
Security Audits: All code undergoes internal review and can be prepared for third-party audits from firms like OpenZeppelin or CertiK.
Full Lifecycle: From initial design and testing to deployment on EVM or Solana mainnets and ongoing maintenance.

We deliver contracts that are secure by design, reducing post-launch vulnerabilities and costly exploits.

Our engineers use established patterns from OpenZeppelin libraries and implement comprehensive test suites covering 95%+ of code paths. We provide clear documentation and a verified contract source code package for transparency.
