CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing Solidity 0.8+ with audited OpenZeppelin libraries and comprehensive unit testing to mitigate risk.
Deliver a secure, auditable, and gas-optimized contract suite in as little as 2-4 weeks for an MVP.
Our full-service development includes:
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626vaults. - DeFi Primitives: Automated Market Makers (AMMs), staking pools, and governance modules.
- Enterprise Logic: Multi-signature wallets, access control, and upgradeable proxy patterns.
- Full Audit Trail: Complete documentation and deployment scripts for all major testnets and mainnets.
We move beyond basic templates to deliver bespoke contract logic tailored to your specific business rules and tokenomics. Every contract undergoes internal security review and is prepared for third-party audits, ensuring your protocol launches with institutional-grade trust.
Cross-Chain Gas Relay
Frequently Asked Questions
Get clear answers on how our infrastructure simplifies multi-chain user onboarding and transaction execution.
A cross-chain gas relay is infrastructure that allows users to pay transaction fees (gas) on one blockchain using assets from another. You need it to eliminate the #1 user onboarding friction: requiring users to acquire native tokens for gas before they can interact with your dApp. Our service enables users to sign and pay for transactions on Ethereum, Polygon, or Arbitrum using USDC on Solana, for example, creating a seamless multi-chain experience.
