overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from token standards to complex DeFi logic.
We write code that protects your users and your reputation, with zero critical vulnerabilities in production.
- Custom Logic: Build bespoke
ERC-20,ERC-721,ERC-1155, andERC-4626vaults, or complex DeFi primitives like AMMs and lending pools. - Security-First: Development follows OpenZeppelin standards and undergoes rigorous internal review before third-party audit.
- Full Lifecycle: We handle deployment, verification on Etherscan, and provide upgradeability patterns using
TransparentProxyorUUPS. - Gas Optimization: Every contract is optimized for efficiency, reducing user transaction costs by 15-40% on average.

Frequently Asked Questions
Get clear answers on our process, timelines, and technical approach for building secure, interoperable parachain bridges.
A standard XCM bridge connecting a Substrate parachain to an external EVM chain (like Ethereum) typically takes 3-5 weeks from specification to mainnet deployment. This includes 1 week for design/audit, 2-3 weeks for core development and testing on Rococo, and 1 week for final security review and deployment. Complex multi-chain bridges or custom asset logic can extend this to 6-8 weeks.
