Crypto exchange SwissBorg said about 192,600 SOL ($41.5 million) was stolen from an external wallet used exclusively for its SOL Earn strategy on Monday. The exploit stemmed from a partner's compromised application programming interface (API), a mechanism that allows software systems to communicate with one another, affecting a single counterparty, the exchange said in a post on X. It was not a hack of the SwissBorg platform.
