Ripple Inc., a startup behind the XRP cryptocurrency, agreed to invest up to $50m in MoneyGram in a deal that stands to rank among the first crypto-based company investments in a major US publicly-listed firm.

Ripple agreed to buy $30m worth of MoneyGram shares and warrants to buy stock at $4.10 a share, nearly triple the Monday closing price of $1.45 a share. The deal includes additional warrants for up to $20m worth of additional newly issued stock, also at $4.10 a share, over the next two years at MoneyGram’s discretion.
