CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers for your protocol.
- Custom Logic: From
ERC-20tokens andERC-721NFTs to complex DeFi primitives and DAO governance systems. - Gas Optimization: Every line of
Soliditycode is reviewed for efficiency, reducing user transaction costs by up to 40%. - Full Audit Trail: Development includes internal review, automated testing with
Hardhat/Foundry, and preparation for third-party audits.
We deliver a fully verified, deployable codebase with documentation in 2-4 weeks, turning your specification into a live, secure contract on Ethereum, Polygon, or your chain of choice.

Frequently Asked Questions
Get clear answers on how our real-time attestation monitoring service integrates with your identity stack and protects your users.
Our service continuously monitors on-chain attestation registries (like Ethereum Attestation Service) and off-chain Verifiable Credential issuers for changes to your users' credentials. We alert you in real-time to revocations, expirations, suspicious updates, and issuer blacklisting events. This allows you to instantly enforce access control changes in your dApp, such as suspending a user's trading privileges if their KYC credential is revoked.
