CORE INFRASTRUCTURE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications and deployed on-chain.
- Custom Logic & Tokenomics: Tailored
ERC-20,ERC-721,ERC-1155, and bespoke contract logic for DeFi, NFTs, DAOs, and more. - Security-First Development: Built with
Solidity 0.8+andOpenZeppelinlibraries, following industry-standard security patterns. - Full Audit Readiness: Code is structured and documented for seamless review by top security firms like CertiK or Trail of Bits.
- Gas Optimization: Every line is optimized for lower transaction costs and better user experience.
We deliver battle-tested contracts that power your protocol, reducing time-to-market from months to as little as 4 weeks for an MVP.

Frequently Asked Questions
Get clear, technical answers on implementing programmable smart accounts for Bitcoin.
A standard implementation takes 2-4 weeks from kickoff to mainnet deployment. This includes smart contract development, integration with your frontend, and security audits. Complex multi-signature setups or custom opcode integrations may extend this to 6-8 weeks. We provide a detailed sprint-by-sprint project plan during the initial discovery phase.
