overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Security Audits: Every contract undergoes rigorous review using
SlitherandMythX, followed by a formal audit report. - Gas Efficiency: Optimized for cost, with typical gas reductions of 15-30% versus standard implementations.
- Compliance Ready: Built-in support for
ERC-20,ERC-721, and custom standards with pause/upgrade functions for enterprise risk management.
Deliver a secure, audited MVP in as little as 2-3 weeks, backed by a 99.9% uptime SLA for deployed contracts.

CORE INFRASTRUCTURE
Smart Contract Development
Secure, audited smart contracts that power your Web3 product's core logic.
We architect and deploy production-grade smart contracts that are secure, gas-optimized, and upgradeable. Our development process is built on Solidity 0.8+ with OpenZeppelin standards and includes comprehensive unit and integration testing.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626vaults. - DeFi Primitives: Automated market makers (AMMs), lending pools, staking contracts, and yield strategies.
- Governance Systems: DAO tooling, multi-sig wallets, and custom voting mechanisms.
- Security First: Every contract undergoes peer review and formal verification before deployment.
We deliver battle-tested contracts with a focus on security and maintainability, reducing your time-to-market and technical risk.

Frequently Asked Questions
Get clear answers on our integration process, security, and support for your cross-chain payment system.
A standard IBC payment channel integration takes 2-4 weeks from kickoff to mainnet deployment. This includes smart contract development, IBC packet logic, testing, and security review. Complex multi-hop or custom settlement logic can extend this to 6-8 weeks. We provide a detailed project plan in the initial scoping phase.
