E-commerce has transformed global trade by increasing accessibility and convenience, but challenges such as fraud, data breaches, and high intermediary costs still affect trust and efficiency. In Nigeria, these issues are intensified by logistical barriers and low consumer confidence. This study developed a blockchain-based e-commerce platform using the Solana blockchain to enhance transparency, security, and cost efficiency. The system was built with Next.js and integrated with Solana for transaction execution, guided by a prototyping SDLC model. Core features included user authentication, product listings, secure payments, and merchant dashboards. Performance testing on Solana Playground showed an average throughput of 3.2 TPS and transaction confirmation times under one second, with costs below 0.015 SOL per transaction. The results demonstrate Solana’s capability for scalable, low-latency digital commerce, providing empirical evidence of blockchain’s potential for secure, real-time e-commerce operations in emerging markets like Nigeria.
