Prosper Onah

Architected and deployed smart contracts managing over $105M+ TVL for a perpetual DEX with leveraged trading and vault-based risk modeling; designed derivative-like yield products with oracle-bounded pricing; developed Airpuff for leveraging LRTS assets with EigenLayer and restaking primitives; built secure vault strategies and integrated with multiple protocols to support over $120M TVL across the ecosystem.

Led development of Vaultka, a leverage vault system supporting perpetual DEX operations with advanced risk and liquidation logic. Developed Airpuff protocol for leveraging LRTS assets integrating with EigenLayer and restaking primitives. Engineered secure vault strategies with dynamic liquidation, profit-sharing, and asset management. Integrated with GMX, HMX, VELA, KTX Finance, EigenLayer, and other protocols, supporting over $120M in TVL. Built testable smart contracts and orchestrated off-chain logic across Arbitrum, Optimism, zkEVM, and other L2s. Collaborated with multidisciplinary teams to ship fast and secure infrastructure.

Led on-ramp implementation through EIP-7702 and automated liquidity aggregation logic; built Golang-based microservices for a decentralized payment gateway; integrated cross-chain intent-based transactions and account abstraction; contributed to backend services in Golang and Solidity, emphasizing performance and modularity; improved transaction processing with priority queues and RPC-level enhancements, reducing refund rates by 75%.
