overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from concept to deployment.
- End-to-End Development: From initial concept and technical design to deployment on
EVM-compatible chains. - Security-First Approach: All code follows
OpenZeppelinstandards and undergoes rigorous internal review before formal audits. - Proven Patterns: Implementation of established standards like
ERC-20,ERC-721, and custom logic for DeFi, NFTs, and DAOs. - Clear Deliverables: You receive the verified source code, comprehensive documentation, and deployment scripts.
We build the foundational logic your dApp relies on, ensuring it operates as intended—securely and efficiently.

Our Development & Integration Process
A structured, four-phase approach designed for technical founders to achieve production-ready cross-chain payment channels with minimal operational overhead and maximum security.
01
Architecture & Protocol Design
We architect your payment channel network, selecting optimal bridging protocols (e.g., Hyperlane, Axelar, LayerZero) and designing the settlement layer for your specific use case. This phase establishes the technical foundation, security model, and gas efficiency targets.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building custom cross-chain payment channels.
A production-ready cross-chain payment channel network typically takes 6-10 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design, 3-4 weeks for core smart contract development and internal testing, 2 weeks for external audit integration, and 1-2 weeks for deployment and final integration. For simpler, single-asset bridges, timelines can be as short as 4 weeks.
