04Our Services

Compliance, Solved

Flagged wallets, untrusted contracts, and customer identity proof — the biggest blockers for legitimate businesses. We handle all three.

Flag Checker & Resolution

Wallets get flagged by sanctions databases, fraud reports, or false-positive detections. Flagged wallets are restricted from transfers on exchanges and DeFi protocols. We scan, detect, and clear flags via on-chain attestation.

  • Multi-chain scan (ETH, BNB, Polygon, Arbitrum, Optimism, Base)
  • Multi-chain flag & hygiene detection
  • False-positive cleanup for dust attacks and mixer traces
  • One-click on-chain attestation in Trust Wallet
Open Checker

Smart Contract Audits

Comprehensive security review of smart contracts before deployment. We identify vulnerabilities, verify logic correctness, and produce audit reports that satisfy regulatory requirements.

  • Full source code review with line-by-line analysis
  • Automated static analysis + manual verification
  • Reentrancy, overflow, and access-control checks
  • Gas optimization and best-practice recommendations

KYC & Wallet Verification

End-to-end customer verification for exchanges, OTC desks and payment providers: government-ID capture with document review, plus cryptographic proof of wallet ownership via hardware-wallet signature — one guided flow.

  • Guided journey — ID front/back capture with desktop-to-mobile handoff
  • Wallet ownership proof via Ledger-signed on-chain verification
  • Merchant dashboard — link generation, live session monitoring, audit trail
  • Time-boxed sessions & tamper-resistant verification links
Merchant Portal
Common false positives: tokens received from sanctioned mixers, airdrop dust attacks, or shared exchange wallets can trigger flags that restrict legitimate users. Our service identifies and resolves these.

08FAQ

Frequently asked questions

Everything you need to know about the scan, flags and resolution.

What does a Chainscaner check actually scan?
Each check performs a read-only pass across 12 networks: balances and token holdings, dust and spam remnants, active approvals, sanctions and mixer proximity, bridge and cross-hop traces, and gas readiness. No transaction is ever created and no signature is requested.
Is the free check really free?
Yes — one full check per wallet is free, no card or account required. On-chain flag resolution is a Pro Session (€249) that adds deep chain analysis, compliance attestation and a tracked session link.
Do I need to connect a wallet or share a private key?
No. Scans are computed entirely from public ledger state. You only paste an address — private keys are never requested, and a scan can never move funds.
What does a flag mean — and how is it resolved?
Flags mark proximity to sanctioned entities, mixers, darknet clusters, or reported scam and drainer addresses. Resolution re-traces the funding path, separates true exposure from false positives such as dust attacks or shared exchange wallets, and documents the outcome in the report.
Which networks and address types are supported?
12 networks including Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, Celo, Fantom, Cronos, Linea and Scroll — plus TRON endpoints. Both EVM 0x addresses and TRON base58 addresses are accepted.
Is there an API for programmatic access?
Yes — a free read-only JSON API is documented at chainscaner.com/docs. It returns balances, token exposure, approvals and reputation flags; no API key is required for read access during beta.
