Free check
Paste an offer, a message, a wallet address, a transaction or a website link. See which known risk indicators it matches and how strong each one is. Results are information to help you decide, not a verdict.
Open blockchainfraud.org →Check any crypto wallet, offer or message before you send money.
Clear results in seconds: what was found, how strong it is, and what could not be checked. Every paid check is recorded on our own blockchain, so anyone can verify it.
Wallet check for apps and AI agents
Before paying a wallet: pass, review or block against the OFAC, EU and UK sanctions-list addresses and an open scam-address list, with a signed receipt. Paid in USDC, no account.
Use it on PayAPI Market →UnyKorn Chain
Our own blockchain, built in Rust on the Polkadot SDK. Every paid check is fingerprinted onto it, and a daily checkpoint is written to Base, a public network we do not run.
Open the chain explorer →Services and prices
Verdict API
Pass, review or block for a wallet or counterparty, with a signed receipt. Your first call is free; after that $0.02 per call in USDC over x402, no account.
How to call it →Counterparty report
A written report on one counterparty: the entity, its people and its wallets screened against the sources named, with every source and date shown.

One deal room, unlimited documents. Each document is hashed, witnessed on the rail, anchored to UnyKorn Chain every 15 minutes and timestamped on Bitcoin.
