SECURE, AUDITED CODE
Smart Contract Development
Production-ready smart contracts built with security-first development and comprehensive audits.
We architect and deploy secure, gas-optimized smart contracts that form the core of your Web3 application. Our development process is built on industry-standard security patterns and rigorous testing to protect your assets and users.
- Full Lifecycle Development: From initial design and
Solidity 0.8+coding to deployment and maintenance on EVM chains like Ethereum, Polygon, and Arbitrum. - Security-First Approach: All contracts undergo multiple audit stages, including automated analysis, manual review, and formal verification against common vulnerabilities.
- Custom Logic & Integration: Build bespoke DeFi primitives, NFT collections (
ERC-721A), token systems (ERC-20), and complex multi-contract architectures.
We deliver battle-tested code with a 100% audit pass rate for critical vulnerabilities before mainnet deployment, ensuring your protocol's foundation is unshakable.
Gasless Identity Relayer
Frequently Asked Questions
Get clear answers on how our managed relayer service integrates, secures, and scales your user onboarding.
Users sign a typed data message (EIP-712) with their identity wallet (like Privy or Dynamic). This signature is sent to your backend, which authorizes the transaction. Our secure, high-availability relayers then submit the transaction, pay the gas fee, and broadcast it to the network. The user never needs native tokens, sees no gas prompts, and experiences a seamless Web2-like flow.
