Ledger objects on the XRP Ledger have a unique ID, which is a hash of some kind.

Use the ledger_entry method to retrieve an object from the ledger.

The index parameter specifies the unique ID of the object to retrieve.

Some useful ledger object IDs:

  • NegativeUNL: 2E8A59AA9D3B5B186B0B9E0F62E6C02587CA74A4D778938E957B6357D364B244

Here is one way to get the hash:

auto keylet = keylet::negativeUNL();                                                                  
auto key = keylet.key;                                                                                
JLOG(m_journal.info()) << "nunl key : " << strHex(key);

NFT Token IDs

There was a possibility of predicting NFT token IDs by using the sequence. Most NFT brokers look at the created/modified node and compare final/previous fields - in order to get the tokenID after mint. This has become the standard way of getting the newly-minted tokenID.

A snapshot of one week of NFT sales volumes:
