Summary

Sinbad.io was a Bitcoin mixing service that operated from October 2022 until its seizure by U.S., Dutch, and Finnish law enforcement in November 2023. OFAC designated it a key money-laundering tool of North Korea's Lazarus Group, which used it to launder proceeds from multiple major crypto hacks including Axie Infinity's Ronin Bridge and Atomic Wallet. On-chain analytics firms assessed it to be highly likely a rebranding of Blender.io, the first crypto mixer ever sanctioned by OFAC.
