Wallet due diligence means screening a crypto address's on-chain history for AML and sanctions red flags before transacting; Plastron provides that wallet-level due diligence free across seven EVM chains as an informational signal.

Due diligence in crypto means knowing who and what you are transacting with before the transaction happens. In traditional finance, counterparty due diligence is built into every business relationship — banks screen clients, brokers screen customers, and businesses verify their trading partners. In crypto, the pseudonymous nature of blockchain transactions means that due diligence requires a different set of tools: instead of checking a company registration or running a background check, you need to analyze the on-chain transaction history of the wallet address you are dealing with. The need for crypto due diligence arises in a wide range of situations. An OTC desk accepting a large ETH payment needs to confirm the sending wallet does not have sanctions or mixer exposure before crediting the trade. A DeFi protocol considering whitelisting a wallet for governance participation may want to screen it for darknet or fraud links. A business accepting cryptocurrency payments from a new customer should check whether the customer's wallet carries any AML flags before completing the transaction. An individual receiving a large payment to a personal wallet should understand whether the sender's address introduces any exposure before moving those funds to an exchange. In all these cases, the due diligence workflow is the same: scan the counterparty wallet, review the risk report, and make a documented decision about whether to proceed. Plastron makes this workflow available for free, covering the full spectrum of AML risk categories for any Ethereum address.
