Project Summary

Peiko developed a custom smart contract system for an IT outsourcing company, designing architecture, token logic, staking flows, access control and upgradeability while integrating Web3 connections to front-end and wallets. The team deployed contracts to testnet and mainnet, prepared them for audit, and provided comprehensive documentation and automated tests. The implementation was stable and scalable, and gas costs were optimized by over 20%, with milestones delivered on schedule.
