Crystal Blockchain
Crystal provides cryptocurrency analysis and transaction tracing that serves the needs of compliance teams under FATF and 5th AML Directive requirements. With Crystal, PARSIQ users can now access a risk scoring system.
Crystal
It is required to have Pro subscription or higher to gain access to Risk Data Providers.
You need to buy Crystal Blockchain Risk Data calls in addition to your subscription. Contact us at [email protected] to get more info about pricing.
Crystal Blockchain is an advanced blockchain explorer and analytics tool. It helps to understand where cryptocurrencies are flowing from and to. By providing identification for entities behind transactions, Crystal enables risk-based assessment for their users.
The functions getCrystalDataForETH(targetAddress) and getCrystalDataForBTC(targetAddress) take the Ethereum or Bitcoin address and return the structured data from the Crystal Blockchain associated with this address.

Code Samples
This code sample will get data from Crystal Blockchain about the address your Native Ethereum wallet is interacting with. Works both for deposits and withdrawals.
stream QuickMonitor
from Transfers
where @to == MyEthereumAddress || @from == MyEthereumAddress
process
  
  let isCrystalProviderDataReady = false
  let crystalProviderData = {percentRiskScore: "0", decimalRiskScore: {value: 0, decimals: 0}, targetName: "", targetType: "", signals: {atm: "", darkMarket: "", darkService: "", exchange: "", gambling: "", illegalService: "", marketplace: "", miner: "", mixer: "", payment: "", ransom: "", riskyExchange: "", scam: "", stolenCoins: "", trustedExchange: "", wallet: ""}}
  
  let executionTarget = MyEthereumAddress
  let counterpartyAddress = 0x0
  
  if @to == executionTarget then counterpartyAddress = @from
  else counterpartyAddress = @to
  end
  
  let txInfo = { txHash: @tx_hash }
  
  if (!isCrystalProviderDataReady) then
    crystalProviderData = getCrystalDataForETH(counterpartyAddress)
    isCrystalProviderDataReady = true
  end
  
  let crystalProvider_txRiskScore = crystalProviderData.decimalRiskScore
  let crystalProvider_txRiskScore_percent = crystalProviderData.percentRiskScore
  
  
  emit { @from, @to, @value, txInfo, crystalProvider_txRiskScore, crystalProvider_txRiskScore_percent }
​
end
If you want to be notified about the transaction with the address that have a risk score of more than 70%, use this code.
stream QuickMonitor
from Transfers
where @to == MyEthereumAddress || @from == MyEthereumAddress
process
  
  let isCrystalProviderDataReady = false
  let crystalProviderData = {percentRiskScore: "0", decimalRiskScore: {value: 0, decimals: 0}, targetName: "", targetType: "", signals: {atm: "", darkMarket: "", darkService: "", exchange: "", gambling: "", illegalService: "", marketplace: "", miner: "", mixer: "", payment: "", ransom: "", riskyExchange: "", scam: "", stolenCoins: "", trustedExchange: "", wallet: ""}}
  
  let executionTarget = MyEthereumAddress
  let counterpartyAddress = 0x0
  
  if @to == executionTarget then counterpartyAddress = @from
  else counterpartyAddress = @to end
  
  let txInfo = { txHash: @tx_hash }
  
  if (!isCrystalProviderDataReady) then
    crystalProviderData = getCrystalDataForETH(counterpartyAddress)
    isCrystalProviderDataReady = true
  end
  
  let crystalProvider_txRiskScore = crystalProviderData.decimalRiskScore
  let crystalProvider_txRiskScore_percent = crystalProviderData.percentRiskScore
  
  if toSmallestDivisibleUnits(crystalProvider_txRiskScore_percent, 1) >= toSmallestDivisibleUnits("70", 1) then
    emit { @from, @to, @value, txInfo, crystalProvider_txRiskScore, crystalProvider_txRiskScore_percent }
  end
end
