Unmarshal’s Tech Stack for Klaytn


  1. Wallet Transaction History API tracks all asset transfer events within the Klaytn blockchain.
  2. Contract Transaction history API gives the entire transaction history for a particular token, given its contract address.
  3. Decoded Transaction API provides an in-depth description of a particular transaction.
  4. Wallet Balance API to track users’ asset balances.
  5. Price Store API contains endpoints that provide the latest price of a token as well as historical price of the tokens. These can also be LP tokens.
