CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, and NFTs. Our team, with 100+ deployed contracts, uses battle-tested patterns from OpenZeppelin and rigorous internal review processes to mitigate risk.
From a 2-week MVP to a full protocol suite, we deliver code that is secure, gas-optimized, and maintainable.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with advanced features like vesting, staking, and governance. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, yield aggregators, and lending/borrowing logic.
- Security First: Every contract undergoes static analysis, formal verification, and a pre-audit checklist before delivery.
Cross-Chain Confidential Swaps
Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building private cross-chain DEX solutions.
A cross-chain confidential swap is a decentralized exchange (DEX) protocol that enables users to trade assets between different blockchains (e.g., Ethereum to Solana) without exposing their trade amounts or wallet balances on-chain. Our solutions use zero-knowledge proofs (ZKPs) and secure multi-party computation (sMPC) to shield transaction details. The process involves: 1) Locking assets on the source chain into a shielded pool, 2) Generating a cryptographic proof of the valid swap, 3) Relaying the proof via a decentralized oracle network to the destination chain, and 4) Releasing the swapped assets from a shielded pool on the target chain—all without revealing sensitive data.
