Pratyush Shivam developed optimized, audit-hardened Solidity libraries that handle freight escrows, cargo damage claims, and dynamic factoring. By using inline Yul assembly, gas utilization was reduced by 35% compared to standard open-source equivalents.

Security Audit & Signature Verification

All contracts utilize off-chain meta-transactions to enable gasless operations for truck drivers. Drivers sign lightweight EIP-712 payload packages using their hardware keys, which are then submitted to gasless relayers to trigger state updates on-chain.
