Evidence-based EVM, Bitcoin, XRP, and TRON analysis. Multi-network scanning, explainable scoring, AI-assisted reporting.
Scans every supported EVM network automatically. Bitcoin, XRP Ledger, and TRON addresses are detected as single-network analyses.
This analysis is informational and based only on available public blockchain and explorer data. It is not a guarantee of safety, legality, ownership, or compliance status.
The Blockchain Address Analyzer is a free blockchain address checker for anyone who wants to verify a recipient, investigate activity or review a counterparty before sending funds. Paste an address, get an evidence-based risk and activity overview, and keep your wallet disconnected. It is built by Cryptnox for practical crypto security hygiene.
Use the tool as a quick crypto address lookup before you send funds, accept a payment, review a counterparty or investigate unfamiliar activity. It does not require a wallet connection and your browser talks only to Cryptnox’s backend.
The analyzer gives a structured overview of what public data says about an address. It is designed for fast triage, not for replacing block explorers or making legal, compliance or ownership conclusions.
For EVM addresses, the analyzer checks 12 networks from one box: Ethereum, Base, BNB, Arbitrum, Polygon, Optimism, Avalanche, Linea, Scroll, Gnosis, Celo and Mantle. That makes it easier to see whether the same address has meaningful activity across networks without repeating the same lookup many times.
Bitcoin, XRP Ledger and TRON addresses are detected and analysed as single-network checks. You can use it to check an Ethereum address, check a Bitcoin address, check a TRON address or review an XRP Ledger address before taking the next step.
The tool is a multi-network risk-and-activity overview. For deep transaction inspection, it links out to the relevant block explorers so you can examine the original public records directly.
The Risk score is an evidence-based estimate, not a verdict. A low score does not prove that an address is safe, and a high score does not prove wrongdoing. It simply summarises the risk signals the analyzer found in public blockchain network and block-explorer data.
Each heuristic is shown with the on-network evidence that triggered it, so you can see why the signal appeared. Examples include unusual activity patterns, possible spam or airdrop tokens, address type, transaction behaviour and counterparty patterns.
The optional AI summary is generated only from the structured facts already collected by the analyzer. It is there to make the findings easier to read; it does not invent missing data or replace your own judgement.
Many users run a quick check before sending funds to a new recipient. It is a simple step that can reveal whether an address has activity, whether it appears across networks, and whether any visible signals look unusual.
Checking an address is good transaction hygiene. The other half is protecting the keys that authorise your transactions. The analyzer is independent of any wallet and works on public addresses, but secure self-custody matters when it is time to sign.
The Cryptnox hardware wallet is a Swiss-engineered contactless NFC smart-card wallet. Private keys are generated and kept inside a certified EAL6+ secure element, so they never leave the card.
It supports Bitcoin, Ethereum, XRP, TRON and 1000+ EVM networks through the Cryptnox Wallet app and WalletConnect. Use the analyzer to review addresses before you act, and use dedicated hardware security to keep signing keys isolated.
Yes. The analyzer is read-only and never touches your funds, private keys or seed phrase. You paste a public blockchain address, and the tool analyses public data without connecting to your wallet.
The tool is free to use and does not require a wallet connection. It only needs the public address you want to check, and your browser communicates with Cryptnox’s backend rather than calling block explorers directly.
You cannot prove that an address is a scam from a single lookup. The analyzer highlights evidence-based risk signals such as unusual activity, suspicious-looking token noise or notable counterparty patterns. Treat the result as an informed warning system, not a final judgement.
For EVM addresses, it checks Ethereum, Base, BNB, Arbitrum, Polygon, Optimism, Avalanche, Linea, Scroll, Gnosis, Celo and Mantle. It also detects and analyses Bitcoin, XRP Ledger and TRON addresses as single-network checks.
No. A low risk score only means the analyzer did not find strong risk signals in the public data it reviewed. It does not guarantee safety, legality, ownership, future behaviour or compliance status.
Address poisoning is a tactic where an attacker tries to make a lookalike address appear in your transaction history, hoping you will copy the wrong recipient later. Before sending, compare the full address and use a crypto address checker to review whether the address context matches what you expect.
The analyzer uses public blockchain network data and public block-explorer data through Cryptnox’s backend. It does not ask your browser to connect directly to explorers, and it does not use private wallet data.
Cryptnox builds free, browser-based security tools alongside its hardware. If you are verifying ownership or testing keys, these may help:
Reviewing an address is good transaction hygiene; protecting your signing keys is the other half. The Cryptnox hardware wallet is a Swiss-engineered, contactless NFC smart card that keeps your private keys inside a certified EAL6+ secure element — they never leave the card.
