Quantum Portal Multichain Explorer (QPME)

The Quantum Portal Multichain Explorer (QPME) brings together information from Quantum Portal Smart Contracts deployed on multiple chains and provides the ability to interact with these contracts through the Ferrum Virtual Machine (FVM) and its Quantum Portal Node infrastructure.

A Multichain Explorer - QPME

QPME is a Multichain explorer. This means it needs to display data for various chains, this data includes transactions, blocks, and QPME also needs to display the minedQPBs and finalizedQPBs for each chain.
QPME is designed to help users easily search for transactions, addresses, blocks, tokens, and more with the following available search parameters.
Search by:
  1. 1.
    Tx ID
  2. 2.
    Address
  3. 3.
    standardQPB
  4. 4.
    finalizedQPB
  5. 5.
    Token Name & Symbol
Filter by:
  1. 1.
    Source Chain
  2. 2.
    Destination Chain
  3. 3.
    Date Time Range
QPME will also show a stats card showing important information, including:
  1. 1.
    FRM Price
  2. 2.
    Market Cap
  3. 3.
    Number of QP Transactions
Additional relevant information will include:
  1. 1.
    A list of the latest standardQPBs
  2. 2.
    A list of the latest finalizedQPBs
  3. 3.
    A list of the latest transactions
