Do Kwon, the wanted South Korean founder of the failed cryptocurrency Terra, denied on Sunday he was on the run after the Singapore police said he was not in the city-state as had been believed.

Kwon's whereabouts have been thrown into question ­after the Singapore Police Force statement late Saturday, and his tweets did not reveal where he was.

The collapse of Terraform Labs in earlier 2022 wiped out about $40 billion of investors' money.

A South Korean court on Wednesday issued an arrest warrant for Kwon.

Early Sunday he said on Twitter, "I am 'not on the run' or anything similar," but did not reveal where he was.

"For any agency that has shown interest to communicate, we are in full cooperation and we don't have anything to hide," he said.

"We are in the process of defending ourselves in multiple jurisdictions... and look forward to clarifying the truth over the next few months."

The 31-year-old was earlier believed to be in Singapore, where in August he gave his first media interview since the crypto operator folded in May.

Kwon's Terra/Luna system disintegrated in May, with the price of both tokens plummeting to near zero, and the fallout hitting the wider crypto market. Its collapse sparked more than $500 billion in losses.
