CORE SERVICE
Custom Smart Contract Development
Secure, production-ready smart contracts tailored to your specific business logic and deployed on your chosen blockchain.
We architect and build custom Solidity/Rust smart contracts that are audit-ready from day one. Our process ensures your core business logic is immutable, secure, and operates exactly as intended.
- Full Lifecycle Development: From specification and
OpenZeppelin-based implementation to testing and mainnet deployment. - Security-First: Adherence to formal verification patterns and comprehensive unit/integration testing.
- Gas Optimization: Every contract is optimized for minimum execution cost and maximum efficiency.
- Protocol Integration: Native support for
ERC-20,ERC-721,ERC-1155, and custom standards.
Deliver a battle-tested, gas-efficient smart contract system in as little as 4-6 weeks, giving you a secure foundation to build upon.
Cross-Platform Payment Identity
Technical & Commercial FAQs
Answers to the most common technical, process, and commercial questions from CTOs and product leads evaluating identity solutions.
We deliver a production-ready, audited payment identity system in 4-8 weeks from kickoff. This includes smart contract development, integration with your existing payment rails, and a frontend SDK. For a standard ERC-4337/Soulbound Token implementation with 2-3 verification methods, expect 4 weeks. Complex multi-chain deployments with custom KYC/AML logic extend to 8 weeks. We provide a detailed sprint-by-sprint timeline in the project proposal.
