Real-time wallet address screening against global sanctions lists

The platform checks every wallet address against OFAC, EU, UN, and other sanctions lists in under two seconds. This happens at the API level, so it integrates directly into deposit or withdrawal flows without adding friction for legitimate users.

Business outcome: Compliance teams reduce manual review workload by 80% while maintaining regulatory coverage.

Continuous transaction monitoring for suspicious activity

Beyond initial screening, Themis monitors ongoing transaction patterns for behavior that triggers compliance alerts. This includes rapid movements, mixing service interactions, and connections to known high-risk addresses.

Business outcome: Detect and report suspicious activity patterns before regulators flag them.

Automated compliance report generation for auditors

The platform generates structured reports suitable for regulatory submissions. These include screening logs, risk scores, and timestamped audit trails that satisfy most jurisdictional requirements.

Business outcome: Reduce the time spent on compliance reporting from days to minutes per review cycle.

REST API designed for high-volume transaction pipelines

The API handles thousands of screening requests per second with consistent sub-two-second response times. This makes it suitable for exchanges processing high-frequency trading volumes or large batch transfers.

Business outcome: Scale compliance screening to match transaction volume without degrading user experience.

Multi-blockchain support across 50+ networks

Themis covers Ethereum, Bitcoin, Solana, Polygon, and dozens of other chains. This matters for businesses operating across multiple ecosystems who need consistent screening regardless of the underlying blockchain.

Business outcome: Maintain compliance coverage across all blockchains your business touches without multiple tools.

Customizable risk thresholds and alert rules

Compliance teams can adjust screening sensitivity, set custom risk score thresholds, and configure alert routing to match their internal policies. This flexibility is critical for firms operating in jurisdictions with different regulatory requirements.

Business outcome: Tailor compliance workflows to your specific regulatory environment without developer support.

• Speed at scaleSub-two-second screening responses make it viable for high-throughput exchanges without adding transaction delays.
• Multi-chain coverageSupport for 50+ blockchains means one integration covers most ecosystems a crypto business operates in.
• Regulatory report readinessBuilt-in report generation reduces the compliance burden during audits and regulatory submissions.
• API-first designThe API integrates cleanly into existing transaction pipelines without requiring major infrastructure changes.

• No forensic investigation toolsThis is a screening tool, not a blockchain forensics platform — it won't help trace complex money laundering paths.
• Limited DeFi integration depthWhile it covers DeFi protocols, the screening logic is optimized for centralized exchange workflows, not smart contract-native compliance.
• No free tier for testingTeams need to go through a sales process to evaluate the platform, which slows down procurement for smaller firms.
• Professional RealityThemis For Crypto is a specialized screening layer, not a full compliance suite — most enterprises will need to pair it with a broader analytics tool for complete coverage.

Exchange onboarding screening

When a new user deposits crypto for the first time, Themis screens the source wallet against sanctions lists in real time. If a match is found, the deposit can be automatically blocked or flagged for manual review. This prevents sanctioned entities from using the platform without adding minutes to the onboarding flow.

Custodian withdrawal compliance

For custodial wallet providers, every withdrawal address must be screened before funds leave custody. Themis automates this check at API speed, ensuring no sanctioned address receives funds while keeping withdrawal times under a second for legitimate users.

DeFi protocol whitelist screening

DeFi teams can use Themis to screen wallet addresses before adding them to whitelists or allowing them to interact with high-value pools. This adds a compliance layer without requiring users to go through KYC.

Payment processor counterparty checks

Crypto payment processors can screen merchants and their associated wallets before onboarding them. This reduces the risk of facilitating payments to sanctioned entities while maintaining fast merchant onboarding times.
