 ### Retrieving raw transactions
 
-It's possible to get raw transaction data directly from our nodes. In order to do this you should make the following API call: `https://api.blockchair.com/{chain}/raw/transaction/{txhash}` (where `{chain}` can be one of those: `bitcoin`, `bitcoin-cash`, `ethereum`, and `litecoin`)

 The response contains two keys which are:
 * `raw_transaction` - raw transaction represented as hex string
-* `decoded_raw_transaction` (not available for Ethereum) - raw transaction encoded in JSON by our nodes. Please not that the structure of this JSON array may change as we upgrade our nodes, and this won't be reflected in our change logs.
