# Indexers

####

Querying data directly on a blockchain can be resource-intensive and slow, posing challenges for decentralised applications (dApps) that rely on real-time data. SFI L2 addresses this issue by implementing an indexing layer designed for speed and scalability.

Indexers collect and structure blockchain data, converting raw transaction records into accessible formats. This allows developers to retrieve specific information, such as token balances, transaction histories, or application analytics, without overloading the network. Moreover, by reducing repetitive tasks, indexers improve the efficiency and responsiveness of dApps.

On SFI L2, an RWA platform can utilise indexers to display real-time asset performance metrics to investors, while DeFi applications can access up-to-date liquidity and price data through indexers to provide users with timely market insights.
