Compliance Challenges for Wallet & Custody Providers

Regulators worldwide are extending AML requirements to wallet providers and custodians. Staying compliant while delivering a seamless user experience is a growing challenge.

New Regulations Target Wallets

The EU Transfer of Funds Regulation (TFR), MiCA, and updated FATF guidance now require non-custodial wallet providers to implement AML measures. Even self-custody wallet services face compliance obligations in many jurisdictions.
User Transfers to High-Risk Addresses

When users send funds to mixers, sanctioned wallets, or darknet markets, your platform may be liable. You need real-time risk warnings before transaction execution to protect both users and your business.
Custodian Compliance Obligations

Crypto custodians face the same AML requirements as exchanges: deposit screening, withdrawal monitoring, sanctions compliance, and regulatory reporting. All while managing thousands of client wallets across multiple chains.

How MistTrack Helps Wallet & Custody Providers

Embed compliance directly into your wallet product with lightweight API integration that doesn't compromise user experience.

In-Wallet Risk Scoring

Add a risk check to your send confirmation flow. Call the risk_score API before transaction execution and display risk warnings to users. Sub-500ms response adds no noticeable latency to the user experience.

Address Labels in UI

Show users who they're sending to. Display entity type labels (e.g., "Binance Hot Wallet", "Known Mixer") directly in your wallet's recipient confirmation screen using the Address Labels API.

Frequently Asked Questions

QDo non-custodial wallet providers need AML compliance?

Yes. The EU Transfer of Funds Regulation (TFR) and MiCA regulation now require non-custodial wallet providers to implement AML measures. The FATF has also updated guidance to include unhosted wallet providers. Even if you don't hold user funds, providing a wallet service creates compliance obligations in many jurisdictions.

QHow can I integrate risk scoring into my wallet UI?

Call the GET /v3/risk_score API before confirming any transaction. Display the risk score and level to users in your send confirmation screen. The API returns in under 500ms, so it doesn't add noticeable latency. You can also use the Address Labels API to show entity type (e.g., "Binance Hot Wallet") to users.

QDoes MistTrack support the chains my wallet supports?

MistTrack supports 19 major blockchain networks including all EVM chains (Ethereum, BSC, Polygon, Arbitrum, Base, Avalanche, Optimism, etc.), TRON, Bitcoin, Solana, Litecoin, Dogecoin, and more. We regularly add new chains as the ecosystem grows.

QWhat is the FATF Travel Rule and how does it affect wallet providers?

The FATF Travel Rule (Recommendation 16) requires Virtual Asset Service Providers (VASPs) to collect and share originator and beneficiary information for transfers above certain thresholds. Wallet providers must screen counterparty wallets and identify the receiving entity to comply. MistTrack helps by identifying entity types and flagging high-risk destinations.

QHow does MistTrack help custodians with compliance?

MistTrack helps custodians with: (1) screening all inbound deposits for risk, (2) monitoring outbound withdrawals for sanctions matches, (3) asynchronous task creation for portfolio reviews for periodic audits, (4) generating compliance reports for regulators, and (5) alerting when monitored addresses interact with high-risk entities.

QCan MistTrack monitor transactions in real-time?

Yes. MistTrack KYT (Know Your Transaction) provides real-time transaction monitoring across 19 blockchain networks. Set up custom alert rules for high-risk transactions, sanctioned address interactions, and suspicious patterns. Alerts are delivered via email or webhook.

QWhat is the integration effort for wallet providers?

Integration typically takes 1-3 business days. Our REST API is lightweight and designed for easy integration. Add a single API call to your transaction confirmation flow. We provide SDKs, comprehensive documentation, and integration support for all plan customers.
