The most popular applications on Solana are trading markets and oracles that feed prices to those markets. Solana has always presented itself as the ideal trading platform. Its value proposition is to offer very fast transactions and low fees. These qualities are ideal for trading platforms.

Smart contracts are decentralized programs that form the backbone of all blockchain applications. By tracking the daily number of contracts used, we can get a sense of the growth of the Solana ecosystem.
