Wallet Screening brings real-time blockchain risk to every transaction. Bring your own Crystal or Merkle Science key, plug it into a Didit workflow, and pay $0.02 per screening — about 10× cheaper than going to a blockchain-analytics provider direct. Screen wallets before a transfer, transaction hashes after the fact, and pipe the results straight into the Transaction Monitoring rules engine. Wallet Screening is part of Didit’s Monitoring lifecycle stage — checks that run continuously, post-onboarding, on every flow of funds in or out of your platform.

​
How it works

  1. Connect a provider. In Transactions → Settings → Provider Preferences in the Business Console, add your Crystal or Merkle Science API key (BYOK) or pick the managed option. Default provider is Crystal.
  2. Submit a transaction with crypto details. Set transaction_details.currency_kind: "crypto" and provide a wallet address in the participant matching the transfer direction. Didit screens the wallet (pre-transfer) or the transaction hash (post-transfer) automatically.
  3. Receive a standardised result. Risk score 0-100, severity (LOW, MEDIUM, HIGH, CRITICAL), a source-of-funds breakdown, an exposure table, and a network graph. The result feeds the rules engine and triggers any matching webhooks.

​
Risk signals

Every screening produces a standardised payload regardless of which provider sits behind it:
  • Risk score (0-100) — higher means greater exposure to risky entities.
  • Severity — LOW, MEDIUM, HIGH, CRITICAL derived from the score.
  • Source of funds — percentage breakdown across 14+ categories (sanctioned, terrorist financing, child exploitation, ransomware, stolen funds, darknet markets, mixers, scams, high-risk exchanges, gambling, regulated exchanges, P2P, unidentified services).
  • Exposure table — counterparty entities with direct vs. indirect hop distance, received and sent amounts, per-entity risk level.
  • Network graph — node-edge view of the wallet’s transaction relationships with centrality and depth metrics. Visualised in the Business Console.
  • Sanctions, darknet, and mixer flags — surfaced as discrete signals so rules can decline instantly.

BYOK (Bring Your Own Key) lets you connect your existing commercial agreement with a blockchain-analytics provider and pay Didit only the $0.02 infrastructure fee per screening. If you already pay Crystal or Merkle Science elsewhere, BYOK is the cheapest way to route those screenings through a Didit workflow.

Integration

The full API surface — request payloads, direction rules, pre-transfer vs. post-transfer screening, and the rule-engine integration — lives on the Transaction Monitoring AML Screening page. Wallet Screening is enabled by setting currency_kind: "crypto" on the transaction and toggling the application-level default in the Console.
