Brazil’s B3 stock exchange has launched options on bitcoin, ether (ETH) and solana (SOL) futures, expanding its regulated crypto derivatives lineup. The contracts began trading on July 6, according to CoinDesk, citing a B3 circular. The offering includes call and put options on bitcoin futures denominated in Brazilian reais, while ether and solana futures are denominated in U.S. dollars. The options settle into the underlying futures contracts rather than the tokens, and B3 said they do not involve custody or transfer of spot cryptoassets.
