DAS API and Compression

Solana's most powerful development tool.
With DAS API, you get access to the most versatile and performant NFT and token API on Solana.
With compression, you get access to the most cost-efficient way of minting large numbers of digital assets in all of crypto.

Enhanced Solana APIs

Making sense of Solana data is challenging, as it often appears as series of long, obscure byte data without context. This makes it difficult for you and your users to understand what's going on.
The Enhanced Transactions APIs solve this by providing enriched, descriptive context. Instead of opaque bytes, you see the details of on-chain transactions, such as whether they are NFT listings, DEX swaps, DeFi loans, or DAO votes.

Webhooks and Websockets

Webhooks allow you to respond to on-chain events in real-time. With built-in support for over 70 transaction types and low-latency event streaming, you can automate your app's interactions with the Solana blockchain without spending time on complex smart contract parsers. You can subscribe to different transaction types or account changes. The best part? You can input up to 100 thousand addresses into a single webhook.
