After Three Arrows Capital failed to make the required payments on its loan of 15,250 Bitcoins (BTC-USD) and $350M USD Coins (USDC-USD), crypto broker Voyager Digital (OTCQX:VYGVF), which backed that loan, has officially issued a notice of default to the troubled crypto hedge fund, according to a release dated Monday. The default notice came after Voyager (OTCQX:VYGVF) had disclosed loan exposure of more than $660M to Three Arrows Capital, which suffered massive liquidations after its crypto bets broke down. In addition, Voyager (OTCQX:VYGVF) said it has used up $75M of the $200M credit line extended by Alameda to facilitate customer orders and withdrawals amid turbulent market conditions. Voyager (OTCQX:VYGVF) also said it had approximately $137M of cash and owned crypto assets on hand as of June 24. "We are working diligently and expeditiously to strengthen our balance sheet and pursuing options so we can continue to meet customer liquidity demands," said
