"On December 8, 2020, a donor sent 28.15 BTC — worth approximately $522,000 at the time of transfer — to 22 separate addresses in a single transaction. Many of those addresses belong to far-right activists and internet personalities", the data firm said in a blog post on Thursday evening.
Chainalysis named Nick Fuentes, a prominent right-wing personality who was pictured outside the Capitol building during the riot, as the largest single recipient of funds.
According to the analytics firm, the donor was a computer programmer based in France who has since died.
"We have also gathered evidence that strongly suggests the donor was a now-deceased computer programmer based in France", Chainalysis said.
