Coinone employees "admit to facts" in case regarding token listing bribes
A lawyer for a broker and the former director of the South Korean cryptocurrency exchange Coinone have told a court that their clients "admit the facts of the prosecution". The director, "Mr. Jeon", is accused of accepting more than ₩2 billion (~$1.5 million) in bribes in exchange for listing shady tokens on the exchange. In one case, the exchange was the only platform to list a token called "Furiever Coin", which has been linked to a kidnapping and murder investigation in Seoul.
Four executives were arrested in connection to the investigation in April, under suspicion that they had received ₩2.4 billion (~$2.2 million) in bribes in exchange for listing dozens of coins.
Coinone is one of the most popular South Korean cryptocurrency exchanges. In July 2022, it was among the seven exchanges raided by Korean authorities in the wake of the Terra/Luna collapse, as the country began applying harsher scrutiny to crypto platforms.
Crypto payments firm Unbanked to shut down
The US-based crypto payments and custody platform Unbanked announced in a blog post that they will be shutting down services. The company was founded in 2018, and claimed they wanted to provide regulated, on-shore services to US-based companies hoping to engage with crypto. As is common with blockchain company shutdowns these days, they blamed US regulators. Referring to their choice to build the company in the US, they wrote: "We unfortunately learned... taking this path lead [sic] to a lot of wasted time and excessive costs. To state it bluntly, US regulators are actively trying to stop companies (banks and fintechs) from supporting crypto assets – even when the companies are trying to do it correctly and by the book. Their efforts are working and ultimately limited Unbanked’s ability to raise capital and run a self-sustaining business."
However, Unbanked also let on that their closure was more related to an investment falling through than to any regulatory issues. The company wrote that a $5 million investment was never delivered, and that the company had "exhausted all options" funding-wise.

Transactions stuck on Multichain blockchain bridge due to "force majeure"
The Multichain blockchain bridge, formerly known as Anyswap, encountered an apparent issue as users' funds were delayed for over 24 hours in getting to their destination. Some reported delays since as far back as May 21. The delay was blamed on a backend upgrade "taking longer than expected". Multichain later tweeted that "some of the cross-chain routes are unavailable due to force majeure, and the time for service to resume is unknown". They also announced that they would compensate affected users.
Meanwhile, rumors swirled that the Multichain team had been arrested by Chinese police, though there doesn't seem to be much corroborating evidence of this.
The issues and the rumors sparked a drop in token price of around 30%. Several large parties also appeared to distance themselves from the project and its token, including the Fantom Foundation, which withdrew 449,740 MULTI (~$2.4 million) in liquidity on SushiSwap.
On May 31, Multichain issued a statement that "we are currently unable to contact CEO Zhaojun and obtain the necessary server access for maintenance", and wrote that even more bridges were being impacted by the same issues as in the previous week.
