Success Stories
Real results from teams augmented with our blockchain developers
DeFi Lending Protocol with $50M TVL
Challenge
A team wanted to launch a DeFi lending protocol but needed experienced smart contract developers to ensure security. Previous audit of their prototype found 12 critical vulnerabilities.
Solution
We rebuilt the protocol from scratch with security-first development, formal verification of critical functions, comprehensive testing, and preparation for multiple external audits.
Outcome
Protocol launched with zero security incidents. Achieved $50M TVL within 6 months. Passed audits from Trail of Bits and OpenZeppelin with no critical findings.
DAO Governance Platform for Protocol
Challenge
A DeFi protocol needed a user-friendly governance platform for their DAO. Token holders were not participating in votes due to complex UX and high gas costs.
Solution
We built a governance platform with gasless voting via signatures, delegation, proposal creation, and analytics. The UI makes it easy to understand proposals and their implications.
Outcome
Governance participation increased from 3% to 34%. Average votes per proposal increased 10x. Platform handles $200M in delegated voting power.
