Example Use Cases

Transactions directly served from RPC nodes are raw and require further processing to make usable in a dApp. It's hard and time-consuming to extract the context from a transaction. Was the transaction an NFT listing? A DAO vote? With our transactions API, we parse every protocol and extract this information for you. This can be quite useful for many use cases, such as:
  • UX friendly wallet transaction history
  • UX- friendly blockchain explorer
  • Enhanced querying - i.e., "get all canceled bids on this NFT over 200 SOL"
  • Analytics
  • Taxes
  • Portfolio performance / gains & losses
  • Loyalty programs based on user transaction history
  • Gating based on transaction history - i.e., "only people who've traded over 100 SOL of NFTs"
