reading-onchain-state

To read Solana on-chain state efficiently, use getAccountInfo for single account fetches and apply a 30-second cache with WebSocket subscriptions to maintain low latency and reflect real-time UI updates.

The best way to batch read Solana accounts is using getProgramAccounts with server-side filters, which allows scalable scans while reducing RPC load through TTL-based caching strategies.

To decode Solana account data safely, use IDLs or borsh layouts to deserialize the buffer and guard against missing fields, ensuring the on-chain state is validated correctly before rendering.

You need WebSocket subscriptions for Solana on-chain state reactivity to push real-time updates to the UI, combined with TTL-based caching to balance performance and consistency goals for hot data.

You can use getProgramAccounts for large-scale program scans on Solana by applying server-side filters to optimize the query, reducing RPC load while fetching the required on-chain state efficiently.

You should use getAccountInfo for precise single account state fetches on Solana, whereas getProgramAccounts is better suited for batched program reads requiring scalable scans across multiple accounts.
