333 new addresses hit sanctions lists

A fresh OFAC and EU batch of 333 sanctioned crypto addresses landed since the last update, mostly unattributed chain and Solana.

Between the previous run and today, 333 cryptocurrency addresses newly appeared on the sanctions lists WalletDNA screens against. By issuing authority, OFAC added 327 of these addresses and the EU added 6. The combined list WalletDNA tracks now holds 969 addresses in total.

By chain, the breakdown is 163 addresses of unknown chain, 156 SOL, 7 BTC, 5 ETH, 1 LTC, and 1 XRP. WalletDNA infers chain from address format rather than from any chain label in the OFAC or EU source data, since the issuing authorities do not always state which chain an address belongs to.

What this means for screening work

A batch this size, and this heavy on unknown-chain and Solana addresses, is a reminder that sanctions data does not arrive pre-sorted. If your screening pipeline assumes every address comes tagged with a chain, or filters out anything that isn't BTC or ETH by default, you can miss additions like this one until they're stale.

• 327 of the 333 additions are OFAC listings, 6 are EU listings.
• 163 addresses lack a stated chain and were classified by format inference, not by the source authority.
• 156 additions are SOL addresses, the largest single labeled chain in this batch.

Chain labels here are inferred from address format. Treat the 'Unknown' bucket as unresolved, not as a separate category of risk.

What to actually do

Pull the current OFAC list from the Sanctions List Service or the community-maintained OFAC sanctioned digital currency addresses repository, and cross-check the EU Financial Sanctions Files if your exposure touches EU-linked counterparties. Re-run any wallets or counterparties you've already screened, since a clean result from your last check does not hold against additions made since then.

For the examples published in this batch, several are Ethereum-format addresses listed under the EU designation and others are Bitcoin-format addresses listed under OFAC. Confirm chain and listing authority against the primary source before you act on any single address, rather than relying on inferred formatting alone.

WalletDNA's sanctions screening pulls from OFAC and EU list updates like this one, so you can check an address against the current combined list without rebuilding the comparison yourself.
