A DeFi compliance check screens a wallet's protocol interactions for exposure to exploits, mixers and sanctioned contracts; Plastron runs that check free across seven EVM chains as an informational risk signal, not licensed compliance.

Decentralized finance creates AML compliance challenges that simply did not exist in traditional finance. When you swap tokens on a DEX, the counterparty to your swap may be a liquidity pool that contains funds from dozens of sources — some clean, some not. When you provide liquidity, you share a pool with anonymous depositors who may include mixers, exchange hackers, or sanctioned entities. When you bridge assets across chains, you interact with contract infrastructure that has been used by sophisticated actors to obscure fund origins. None of these interactions show up as obviously problematic in your wallet history — they look exactly like normal DeFi activity, because they are. But they accumulate counterparty relationships that blockchain analytics systems later classify as risk exposure. The consequence is that experienced DeFi users who have been active across protocols for years often have the most complex compliance profiles — not because they did anything wrong, but because extensive DeFi interaction naturally produces more counterparty relationships, including some with risk-classified addresses. When these users try to deposit to a regulated exchange, their complex counterparty graph generates more compliance questions than a simple buy-and-hold wallet. Plastron's DeFi compliance check is specifically designed for active DeFi participants: we analyze your full counterparty history across ETH transactions, ERC-20 transfers, and internal smart contract calls, identifying exactly which DeFi interactions created compliance exposure and at what severity level.
