Crypto Wallet Screening

How WatchTower screens supported wallet addresses against enabled official sources and preserves match evidence for investigation.

Chain-aware input

Validate wallet identifiers using the network supplied with the transaction.

Official-source matches

Preserve the source, version, and direct match evidence used in the decision.

Analyst-ready context

Keep crypto amounts, fiat equivalents, direction, and wallet evidence together.

What the current capability covers

WatchTower can compare a normalized crypto wallet address with wallet identifiers published in the official sources enabled for the organization. A direct exact match can produce a sanctions signal and follow the organization decision policy.

Wallet screening is separate from person and business name screening. This prevents a wallet identifier from being treated as a name and keeps the evidence type clear for analysts.

Supported network families include

  • Bitcoin
  • Ethereum and EVM-compatible networks
  • Tron
  • Solana
  • BNB Smart Chain
  • Polygon
  • Arbitrum
  • Optimism
  • Base
  • Avalanche C-Chain

Information to send

  • the wallet address
  • the blockchain network
  • the transaction hash when available
  • the crypto asset and amount
  • the fiat equivalent and currency when available
  • the direction, such as deposit, withdrawal, transfer, or payout
Keep crypto and fiat values separate

Send the native asset amount and the fiat equivalent as separate fields. This lets analysts understand both the blockchain movement and its financial value.

What analysts see

When a wallet match is found, the case keeps the chain, masked wallet identifier, source, list version, match type, transaction context, and decision history together. Source links should lead to a reviewable official page where one is available.

Current limitations

Official-list screening answers whether the exact submitted wallet appears in an enabled source. It does not calculate indirect exposure to nearby wallets or identify every illicit blockchain pattern.

A blockchain intelligence provider is required for

  • address clustering and ownership attribution
  • indirect exposure and transaction tracing
  • mixer, ransomware, scam, darknet, and typology labels
  • risk scoring based on blockchain history
Do not overstate coverage

A clear result means no direct match was found in enabled sources. It does not confirm that the wallet has no illicit exposure.
